Arthropods of the class ARACHNIDA, order Araneae. Except for mites and ticks, spiders constitute the largest order of arachnids, with approximately 37,000 species having been described. The majority of spiders are harmless, although some species can be regarded as moderately harmful since their bites can lead to quite severe local symptoms. (From Barnes, Invertebrate Zoology, 5th ed, p508; Smith, Insects and Other Arthropods of Medical Importance, 1973, pp424-430)

Hypersensitivity in the anterior median eye of a jumping spider. (1/701)

Changes in sensitivity of the photoreceptor cells of the anterior median eye of the jumping spider Menemerus confusus Boes. et Str. have been studied by recording electroretinograms (ERGs) and receptor potentials. The amplitudes of the responses (ERGs and receptor potentials) increase during repetitive stimulation, with a maximum increase at 3-5 s intervals. The sensitivity of the photoreceptor cell is greater for about 60 s following illumination (maximum magnitude at 3-5 s) than it is during complete dark adaptation. This phenomenon, which we call 'hypersensitivity', is lost within one day following surgery in physiological saline. Upon loss of hypersensitivity, the sensitivity decrease during light adaptation is greater than for the normal eye and the small increase of sensitivity following the onset of illumination observed for the normal eye is lost.  (+info)

Purification from black widow spider venom of a protein factor causing the depletion of synaptic vesicles at neuromuscular junctions. (2/701)

The aqueous extract of the venom glands of black widow spiders was fractionated on a column of Sephadex G-200 and then on a column of DEAE-Sephadex A-50 pH 8.2. A protein fraction was obtained that caused a great increase in the frequency of occurrence of miniature end plate potentials at the frog neuromuscular junction, and caused swelling of the nerve terminals and depleted them of their vesicles. The fraction consists of a least four protein components that are similar in their molecular weights (about 130,000) and isoelectric points (ranging from pH 5.2 to 5.5) and are immunologically indistinguishable. It contains no sugar residues and has little or no lipolytic or proteolytic activity. The fraction is toxic to mice and is different from the fractions that act on houseflies, the crayfish stretch receptor and the cockroach heart. It seems pure enough to warrant a detailed study of its site and mode of action.  (+info)

Sexually transmitted chemical defense in a moth (Utetheisa ornatrix). (3/701)

The arctiid moth Utetheisa ornatrix is protected against predation by pyrrolizidine alkaloids (PA) that it sequesters as a larva from its food plant. Earlier work had shown that males transmit PA to the female with the sperm package and that the female bestows part of this gift on the eggs, protecting these against predation as a result. We now show that the female herself derives protection from the gift. Females deficient in PA are vulnerable to predation from spiders (Lycosa ceratiola and Nephila clavipes). If mated with a PA-laden male, the females become unacceptable as prey. The effect takes hold promptly and endures; females are unacceptable to spiders virtually from the moment they uncouple from the male and remain unacceptable as they age. Chemical data showed that the female allocates the received PA quickly to all body parts. We predict that other instances will be found of female insects being rendered invulnerable by receipt of sexually transmitted chemicals.  (+info)

Voltage-activated potassium outward currents in two types of spider mechanoreceptor neurons. (4/701)

We studied the properties of voltage-activated outward currents in two types of spider cuticular mechanoreceptor neurons to learn if these currents contribute to the differences in their adaptation properties. Both types of neurons adapt rapidly to sustained stimuli, but type A neurons usually only fire one or two action potentials, whereas type B neurons can fire bursts lasting several hundred milliseconds. We found that both neurons had two outward current components, 1) a transient current that activated rapidly when stimulated from resting potential and inactivated with maintained stimuli and 2) a noninactivating outward current. The transient outward current could be blocked by 5 mM tetraethylammonium chloride, 5 mM 4-aminopyridine, or 100 microM quinidine, but these blockers also reduced the amplitude of the noninactivating outward current. Charybdotoxin or apamin did not have any effect on the outward currents, indicating that Ca2+-activated K+ currents were not present or not inhibited by these toxins. The only significant differences between type A and type B neurons were found in the half-maximal activation (V50) values of both currents. The transient current had a V50 value of 9. 6 mV in type A neurons and -13.1 mV in type B neurons, whereas the V50 values of noninactivating outward currents were -48.9 mV for type A neurons and -56.7 mV for type B neurons. We conclude that, although differences in the activation kinetics of the voltage-activated K+ currents could contribute to the difference in the adaptation behavior of type A and type B neurons, they are not major factors.  (+info)

Effects of size, motility and paralysation time of prey on the quantity of venom injected by the hunting spider Cupiennius salei. (5/701)

Previous experimental studies have shown that neotropical wandering spiders (Cupiennius salei) inject more venom when attacking larger crickets. It has been postulated that this is a consequence of predator-prey interactions during envenomation, which increase in intensity with the size of a given prey species. The present study was designed to test this hypothesis using anaesthetized crickets of different sizes that were moved artificially. Cupiennius salei was found (1) to inject more venom the greater the intensity of the struggling movement of the crickets (prey size kept constant); (2) to inject more venom the longer the duration of the struggling movement of the crickets (prey size and intensity of movement kept constant); and (3) to inject equal amounts into crickets of different size (duration and intensity of movement kept constant). These results indicate that C. salei alters the amount of venom it releases according to the size and motility of its prey. Venom expenditure depends mainly on the extent of the interactions with the prey during the envenomation process, whereas prey size is of minor significance. The regulation of venom injection in concert with behavioural adaptations in response to various types of prey minimizes the energetic cost of venom production, thus increasing the profitability of a given prey item.  (+info)

Inhibition of glutamate uptake by a polypeptide toxin (phoneutriatoxin 3-4) from the spider Phoneutria nigriventer. (6/701)

Glutamate concentration increases significantly in the extracellular compartment during brain ischaemia and anoxia. This increase has an important Ca(2+)-independent component, which is due in part to the reversal of glutamate transporters of the plasma membrane of neurons and glia. The toxin phoneutriatoxin 3-4 (Tx3-4) from the spider Phoneutria nigriventer has been reported to decrease the evoked glutamate release from synaptosomes by inhibiting Ca(2+) entry via voltage-dependent Ca(2+) channels. However, we report here that Tx3-4 is also able to inhibit the uptake of glutamate by synaptosomes in a time-dependent manner and that this inhibition in turn leads to a decrease in the Ca(2+)-independent release of glutamate. No other polypeptide toxin so far described has this effect. Our results suggest that Tx3-4 can be a valuable tool in the investigation of function and dysfunction of glutamatergic neurotransmission in diseases such as ischaemia.  (+info)

The mechanical design of spider silks: from fibroin sequence to mechanical function. (7/701)

Spiders produce a variety of silks, and the cloning of genes for silk fibroins reveals a clear link between protein sequence and structure-property relationships. The fibroins produced in the spider's major ampullate (MA) gland, which forms the dragline and web frame, contain multiple repeats of motifs that include an 8-10 residue long poly-alanine block and a 24-35 residue long glycine-rich block. When fibroins are spun into fibres, the poly-alanine blocks form (&bgr;)-sheet crystals that crosslink the fibroins into a polymer network with great stiffness, strength and toughness. As illustrated by a comparison of MA silks from Araneus diadematus and Nephila clavipes, variation in fibroin sequence and properties between spider species provides the opportunity to investigate the design of these remarkable biomaterials.  (+info)

Spider hemocyanin binds ecdysone and 20-OH-ecdysone. (8/701)

Fluorescence quenching studies and binding experiments with [(3)H]ecdysone reveal that the respiratory protein, hemocyanin, of the tarantula Eurypelma californicum binds ecdysone. The binding constant for ecdysone ranges between 0.5 and 5 mM, indicating a low affinity binding. However, it is comparable with those found for the ecdysone binding to hexamerins from insects. Based on a comparison of sequences and x-ray structures of arthropodan hemocyanins, we propose an evolutionary conserved hydrophobic pocket in domain 1 of the hemocyanin subunit that may bind ecdysone.  (+info)

Spider major ampullate silk is a promising biomaterial, combining high strength and elasticity (Gosline et al., 1986). Furthermore, silk is biocompatible (Allmeling et al., 2006; Gellynck et al., 2006). Potential applications range from artificial tendons and ligaments (Kluge et al., 2008) to microspheres for drug delivery (Lammel et al., 2008). However, large amounts of spider silk are hard to obtain. Researchers are therefore working to produce synthetics fibers based on spider major ampullate silk (Vendrely and Scheibel, 2007). However, in contrast to most known materials, silk supercontracts under mild conditions (when humidity rises above ∼70%) (Work, 1977). During supercontraction, water infiltrates the silk and causes it to shrink, up to half its dry length (Work, 1977). This process also generates high stresses if the fiber is restrained. Supercontraction could play a critical role in the production of dragline silk by spiders by allowing spiders to tailor silk properties (Guinea et ...
Cupiennius salei is a large spider with distinct sexual dimorphism. The females are relatively larger than the males, measuring up to 3.5 cm in body length, with a 10 cm legspan. The dorsal side of the body is chocolate-brown with small, lighter spots on the abdomen and many darker longitudinal stripes, particularly on the carapace. The ventral side is red-orange with thick black central region under the abdomen. Males measure up to 2.5 cm long and have very long and thin legs. The males are much lighter in colour than the females. They are distinct, with conspicuous palpal bulbs.[6] Cupiennius salei have one pair of principal eyes and three pairs of secondary eyes located on the prosoma (the anterior end of the head) and they are colour blind.[7] Being adapted to nocturnality, their visual capability is reduced and they rely on their tactile sensation to detect movements or vibrations in their environment.[6] Under laboratory conditions, females make cocoons every three to four weeks, each ...
The Central American hunting spider Cupiennius salei, like most other spiders, has eight eyes, one pair of principal eyes and three pairs of secondary eyes. The principal eyes and one pair of the secondary eyes have almost completely overlapping visual fields, and presumably differ in function. The retinae of the principal eyes can be moved independently by two pairs of eye muscles each, whereas t ...

With would-be goblins and ghosts set to drape those huge fake spider webs over doorways and trees for Halloween, scientists in Wyoming are reporting on a long-standing mystery about real spider webs: It is the secret of spider web glue. The findings are an advance toward a new generation of biobased adhesives and glues green glues that replace existing petroleum-based products for a range of uses. A report on the study is in the October issue of ACS Biomacromolecules, a monthly journal.. Omer Choresh and colleagues note that much research has been done on spider web silk, which rivals steel in its strength. However, scientists know comparatively little about web glue, which coats the silk threads and is among the worlds strongest biological glues. Past studies revealed that spiders make web glue from glycoproteins, or proteins bits of sugar attached.. The scientists analyzed web glue from the golden orb weaving spider, noted for spinning intricate webs. They identified two new ...
Spider silk has the potential to be a useful biomaterial due to its high tensile strength and elasticity. It is also biocompatible and biodegradable, making it useful for wound dressings and sutures, tissue and bone scaffolds, vessels for drug delivery, and ligament and tendon replacements. In some studies where spider silk has been used to grow cells, the silk has promoted more cell growth than the control. However, it is difficult to obtain the high volume of silk needed for these undertakings on a large scale. Spiders are territorial and cannibalistic, so they cannot be easily farmed. Therefore, spider silk proteins are frequently produced in other organisms. E. coli is often used for spider silk production due to the relative ease of gene manipulation and the cost effectiveness of large-scale fermentation. However, due to the large protein size of the spider silk and the repeating amino acid motifs, there are some challenges with production in E. coli. Metabolic modeling is a way to model the
This study documents the effect of body mass on the size and strength of draglines produced by the orb-weaving spider Araneus diadematus and the jumping spider Salticus scenicus. Silk samples obtained from individuals spanning the range from first-instar juveniles to gravid adults were tested to determine both the properties of the silk material and the strength and static safety factor of the draglines produced by each individual spider. Analysis of material properties indicates that the tensile strength and extensibility of the silks employed by each species are identical over the entire size range of the species. Analysis of the breaking forces for individual draglines, however, indicates that the draglines scale allometrically with the spiders body mass. For Araneus, breaking force (N) scales with body mass (kg) as Fmax=11.2M0.786, and the static safety factor (SBW=Fmax/Mg) scales as SBW=1.14M-0.214. For Salticus, Fmax=0.363M0.66 and SBW=0.037M-0.34. Thus, static safety factors decrease as ...
e investigation of arthropod populations in typical farmland will clarify and encourage the conservation value of these communities and will also contribute towards the development of more sustainable agricultural practices. The habitat preferences of Lycosa hilaris Koch (Lycosidae) and some of the environmental factors that may influence this species have been studied. Lycosa hilaris was chosen for this study as it has been reported as having a wide distribution in many natural ecosystems in New Zealand. Pitfall trapping was carried out over a period of four months (September 1999 to December 1999) to sample L. hilaris from four different habitats on a typical sheep farm in Canterbury, New Zealand. A total of 1549 spiders were captured. Adult male spiders were the most abundant, followed by females and juveniles (78.4, 18.6, and 3 percent, respectively). The total number of spiders caught in pitfall traps was lowest in September and December. Habitat preference was studied by examining, a) ...

Wolf spiders are much maligned, but magnificent and beneficial neighbors of mankind. Theyll eat your brown recluse spiders for you, if you will only let them do so.
In Drosophila, the T-box genes optomotor-blind (omb) and H15 have been implicated in specifying the development of the dorso-ventral (DV) axis of the appendages. Results from the spider Cupiennius salei have suggested that this DV patterning system may be at least partially conserved. Here we extend the study of the DV patterning genes omb and H15 to a representative of the Myriapoda in order to add to the existing comparative data set and to gain further insight into the evolution of the DV patterning system in arthropod appendages. The omb gene of the millipede Glomeris marginata is expressed on the dorsal side of all appendages including trunk legs, maxillae, mandibles, and antennae. This is similar to what is known from Drosophila and Cupiennius and suggests that the role of omb in instructing dorsal fates is conserved in arthropods. Interestingly, the lobe-shaped portions of the mouthparts do not express omb, indicating that these are ventral components and thus may be homologous to the ...
While there is little information specific to the mating habits of thin-legged wolf spiders, mating habits for wolf spiders (Lycosidae) in general are known. Males typically mount females so that they are facing opposite directions. Females must twist and invert their abdomen so that males can reach around to the ventral side of their abdomen. Males use their pedipalps to transfer sperm into the females epigynum. Thin-legged wolf spiders mate in May and June, after sub-adults that overwintered have molted into their reproductive phase. Mating may reportedly last about 60 minutes in this species. While the catalysts of mate attraction are unknown in this species, females from other wolf spider species, including other species of Pardosa, use pheromones or other chemicals to attract males. Contact pheromones are often used; males detect these pheromones with chemoreceptors on their forelegs and palps. Visual and vibratory cues may also be used. (Buddle, 2002; Jiao, et al., 2011; Stratton, et al., ...
Apparently, you dont need Kevlar to stop bullets. Human skin combined with spider silk-infused goat milk can do the job just as well. Dutch scientists recently brought this combination to life, pushing the limits of science. The project is called 2.6 g 329m/s which is the standard weight and velocity that a Type 1 bulletproof vest can protect against.. Spider silk might not seem like much, but its the toughest of all the silks in existence. Its many times stronger than steel, and its the toughest natural protein fiber. With that much strength, spider silk is capable of a great many things. And when woven together, it could even stop bullets. Jalilia Essaidi thought that perhaps there could be one less layer between the person and the spider silk. Why not combine spider silk with human skin? (It isnt that simple, and the experiment did not include a person.) Theoretically, though, the spider silk protein could take the place of keratin which is responsible for the toughness of human skin. ...
Left. A web casting spider with net in relaxed condition. Right. Net casting spider with web expanded or stretched by spider. Images courtesy of Peter Chew, Brisbane Insects.. MANAGEMENT AND CONTROL OF SPIDERS. The first consideration in spider control is to determine whether or not the spiders are living indoors. Most of the domestic spiders are small in size (usually 1/4), uniformly colored (pale yellow, tan or gray), and not hairy in appearance. The one large spider that occurs indoors is the daddy-longlegs spider. Those spiders, which are casual invaders, and which would normally reside outdoors, are usually large (1/2 or more), hairy, distinctly patterned (even brightly colored), and usually jump or run quickly.. General sanitation, both indoors and outdoors, is very important in spider control. Clean up all woodpiles, rocks, trash, compost piles, old boards, and other debris. Exercise caution when working around any materials that have been stockpiled for any length of time. All ...
Habronattus is a diverse clade of jumping spiders with complex courtship displays and repeated evolution of Y chromosomes. A well-resolved species phylogeny would provide an important framework to study these traits, but has not yet been achieved, in part because the few genes available in past studies gave conflicting signals. Such discordant gene trees could be the result of incomplete lineage sorting (ILS) in recently diverged parts of the phylogeny, but there are indications that introgression could be a source of conflict. To infer Habronattus phylogeny and investigate the cause of gene tree discordance, we assembled transcriptomes for 34 Habronattus species and 2 outgroups. The concatenated 2.41 Mb of nuclear data (1877 loci) resolved phylogeny by Maximum Likelihood (ML) with high bootstrap support (95-100%) at most nodes, with some uncertainty surrounding the relationships of H. icenoglei, H. cambridgei, H. oregonensis, and Pellenes canadensis. Species tree analyses by ASTRAL and SVDQuartets gave

Diffraction patterns of N. pilipes and Cyrtophora draglines resemble each other. Crystals of two kinds are identified in these draglines; one is aligned parallel to the silk direction and another is less oriented. The less oriented crystal in Cyrtophora dragline is aligned better than that in N. pilipes dragline, ...
The use of functionalised recombinant spider silk as a sustainable advanced biomaterial is currently an area of intense interest owing to spider silks intrinsic strength, toughness, biocompatibility and biodegradability. This paper demonstrates, for the first time, the site-specific chemical conjugation of different organic ligands that confer either antibiotic or fluorescent properties to spider silk. This has been achieved by the incorporation of the non-natural methionine analogue L-azidohomoalanine (L-Aha) using an E. coli methionine auxotroph and subsequent copper catalysed azide-alkyne cycloaddition (CuAAC) or click chemistry functionalisation of 4RepCT3Aha. The 4RepCT3Aha protein can be modified either prior to, or post fibre formation increasing the versatility of this approach as demonstrated here by the formation of silk fibres bearing a defined ratio of two different fluorophores uniformly distributed along the fibres. Silk decorated with the fluoroquinone family broad spectrum ...

Jumping spiders (Salticidae) are easily distinguished from other spiders by their four big eyes on the face and four smaller eyes on top of the head. Around the world there are probably more than 5000 species of jumping spiders.. Jumping spiders are charming spiders that look up and watch you. Their excellent vision allows them to hunt much as do cats, spotting prey from long distances, creeping up then pouncing using their jumping ability. Although a jumping spider can jump more than thirty times its body length, none of its legs has enlarged muscles. The power for jumping probably comes from a quick contraction of muscles in the front part of the body increasing the blood pressure, which causes the legs to extend rapidly much as in the toy frogs that hop when you squeeze a bulb.. Their vision also allows communications by visual means, such as the elaborate courtship dances that males perform. Salticids are perhaps as old and diverse as mammals, though not many humans know their world. Many ...
Spiders are generally good to have around, as they help minimize the population of harmful insects. The problem arises, however, when they negatively affect humans. The mere sight of a spider can be a real scare for some people. Aside from that, many spiders do bite humans and are poisonous, so it is a good idea to have a pest control company address your spider infestation.. Several spiders pose a serious threat to humans. The two that are the deadliest to humans in the United States are the Black Widow and the Brown Recluse. Since a few people die each year from the bite of either of these two spiders, its extremely important for any person who is bitten by one of these spiders to seek treatment immediately. In some cases, hospitalization may be necessary.. The Black Widow spider can be easily recognized because she is black with a red hourglass on the underside of her abdomen. The male is considerably smaller than the female, and he has a body up to half an inch long. The Black Widow ...
FUKUOKA-A venomous spider endemic to Australia has established colonies across Japan after apparently being brought in on cargo containers.. The red-back spider was first identified in 1995 in Takaishi, Osaka Prefecture, experts say, and by Oct. 1 the spider had reached 22 prefectures, the majority of them in western Japan.. In September, a spider bit a woman in her 80s from the Higashi Ward of Fukuoka city. She suffered breathing difficulties.. While the spiders are not aggressive, the female spider has a virulent poison that can cause spasms and fever. Deaths have been recorded in Australia.. I have become more aware of whether there are spiders in areas where children play, said Mikiyasu Koga, 44, who was recently taking his 4-year-old daughter to a park on Higashi Wards Island City.. Japans Environment Ministry has said the red-back spider is often found near Japanese ports. Officials believe it originally arrived aboard cargo..

How adults influence their childrens views on spiders, will greatly affect how their children treat spiders when they grow up. We can teach them about the spiders important role in the ecosystem around the house, in agriculture, and in the wild. If it wasnt for spiders, the insects that we dont like would take over the world by eating our crops, forests, and spreading disease. Yet, in conventional agriculture, farmers still use broad spectrum pesticides that kill both pests and beneficial animals. Homeowners even spray and squash spiders, even though spiders help keep mosquitoes away from their front porch, flies and moths from entering their home, and caterpillars off their vegetables. With more songs like Spiders by Bruce Haack, childrens books about spiders, and education, spiders can take back their reputation, and get the respect they deserve ...
In addition to preserving spiders anatomy in very fine detail, pieces of amber show spiders mating, killing prey, producing silk and possibly caring for their young. There seems to be an evolutionary trend towards a reduction in the amount of sticky silk used, leading to its total absence in some species. [46][58], Many of the family Theraphosidae, which includes tarantulas and baboon spiders, have urticating hairs on their abdomens and use their legs to flick them at attackers. Australian funnel web spiders are a promising source, as most of the worlds insect pests have had no opportunity to develop any immunity to their venom, and funnel web spiders thrive in captivity and are easy to milk. [70] However, a laboratory study showed that spiders reduce the building of these decorations if they sense the presence of predators. AM (anterior median) The construction of cobwebs is less stereotyped than that of orb-webs, and may take several days. Misumena vatia for instance can change its body ...
Arachnophobia anyone?. Thats the question YouTube user Danny Ford asked when he posted the video online. We got a bit of a surprise when I squashed it with a broom as hundreds of baby spiders came crawling out of the mother.. The mother wolf spider was found in Hallett Cove, South Australia, and those babies didnt crawl out of her, they climbed off of her. When the spiderlings hatch, they climb on the mother's abdomen and spend their first days there before dispersing, arachnologist Norman I. Platnick told National Geographic. So these spiderlings were on the mother, and did not crawl out of her. Wolf spiders are doting mothers that carry a nursery on their abdomen. And with so many little spiderlings clinging to her every move, its a good thing she has eight eyes-four on the top row, and two rows with two eyes each beneath that. In the video below, a man crushes the mother spider with a broom and her babies scatter off in all directions. ...

Spiders represent one of the most studied arachnid orders. They are particularly intriguing from a cytogenetic point of view, due to their complex and dynamic sex chromosome determination systems. Despite intensive research on this group, cytogenetic data from African spiders are still mostly lacking. In this study, we describe the karyotypes of 38 species of spiders belonging to 16 entelegyne families from South Africa and Namibia. In the majority of analysed families, the observed chromosome numbers and morphology (mainly acrocentric) did not deviate from the family-level cytogenetic characteristics based on material from other continents: Tetragnathidae (2n♂ = 24), Ctenidae and Oxyopidae (2n♂ = 28), Sparassidae (2n♂ = 42), Gnaphosidae, Trachelidae and Trochanteriidae (2n♂ = 22), and Salticidae (2n♂ = 28). On the other hand, we identified interspecific variability within Hersiliidae (2n♂ = 33 and 35), Oecobiidae (2n♂ = 19 and 25), Selenopidae (2n♂ = 26 and 29) and Theridiidae (2n♂ =
This beautiful spider is a Golden Orb Weaver in the family Nephilidae (formerly grouped under the Araneidae and Tetragnathidae). The genus is Herennia, and it has an Australasian distribution (India to the Solomon Islands). This is a very small genus with only 11 known species, usually referred to as Coin Spiders, most of which have been described only within the last decade. The island of Java apparently has two species; H. multipuncta is widespread throughout South and Southeast Asia and H. etruscilla is endemic to Java. There are several online images of H. multipuncta and they dont match the one in this post. The definitive paper on the genus is A Revision of Herennia (Araneae: Nephilidae: Nephilinae), the Australasian coin spiders by Kuntner (2005), in which both the detailed descriptions and photos of H. etruscilla provide a very good match to Mohamads spider. The unique webs are referred to as ladder webs and if you are interested in learning more you can check out another paper by ...
Spiders Hide in the DuskIf you know my work, you know that I sneak a spider and a web into many of my creations. I am in awe of the beauty of a spiderweb, but deathly afraid of real-life spiders! In recreating a spiderweb, I try to capture the beauty of the delicate woven structure. However, when I embroider the spider, I try to create a more whimsical version to somehow confront my fear!The project above is one that I designed for my latest book, Beaded Embroidery Stitching. It can be found on page 102.

If he manages to successfully approach the female, the male will insert one of his pedipalps into the female, release his sperm and then-die. (See Male Spiders Give Back Rubs to Seduce Their Mates.). While the males heart is technically still beating-which it will continue to do for up to two hours-he lies immobile and helpless. This give the female ample opportunity to liquidize her mate, squirting out digestive enzymes onto the male for easier eating. This creates a sloshy milkshake, and thats what gets sucked in, Schwartz said.. Not only does it satiate the female, it may prevent her from mating with another male and possibly birthing the rival spiders offspring.. Genital Mutilation. During copulation, the male spider can also lose parts of his genitalia. When the bulb carrying a male spiders sperm expands, it often gets broken off inside the female. This creates a plug that prevents the female from mating again, and ensures that the males sperm will fertilize as many eggs as ...
The spider expertly generates, and eventually releases, tension by waiting for prey in the corner of its triangular shaped web where main radial threads converge with its body. Its body acts as a link between an anchor line connected to cross threads and a trap line connected to the main triangle of the web. In preparing for action, the spider moves backward along the anchor line in a unique leg-over-leg motion that pulls the springy web taut, loading it with immense energy over multiple tightening cycles. When a prey lands on the web, the spider releases its grip on the anchor line, and both the spider and web instantly surge forward. The action also causes multiple lines of spider silk to slam into and fully entangle the prey. Any further forward movement ceases as slack is removed from the anchor line caused by the spider squeezing its internal spinnerets so that no more silk is produced. If the prey is exceptionally large or vigorous, the spider can repeat its unique actions multiple times ...
Thread- and cable-like objects are ubiquitous in our daily environment, and usually fastened to structures and buildings by cumbersome mechanical attachment devices like hooks, clamps, knots and screws. To find better attachment solutions for technological applications, animal models may reveal novel mechanisms of how to attach material to substrates. For example, orb-web spiders are both climbers and architects using silk cables with fascinating elegance and efficiency. A crucial part of both abseiling and web building is the attachment of the main silk thread (the dragline) to substrates, which is performed with remarkable speed and without any pre-preparation or penetration of the substrate. For substrate attachment spiders use numerous short glue-coated nanofibres drawn from the piriform glands [1,2]. Both the dragline-producing major ampullate gland and the piriform gland ducts lead to nozzle-like openings, the spigots, located on the paired anterior lateral spinnerets. In order to attach ...
lt of his research, that it would not be possible to make it by taking it directly from spiders. This being the case, scientists then came up with the idea of the production of artificial spider silk as an alternative. But, before that, it was necessary for the researchers to find out how the spider produces the silk. This took quite a few years. The zoologist Vollrath discovered an important part of the method in his later work. The spiders method is remarkably similar to the process used to manufacture industrial fibers such as nylon: spiders harden their silk by acidifying it. Vollrath concentrated his work on the garden cross spider known as Araneus diadematus and examined a duct through which the silk flows before exiting. Before entering the duct, the silk consists of liquid proteins. In the duct, specialized cells draw water away from the silk proteins. Hydrogen atoms taken from the water are pumped into another part of the duct, creating an acid bath. When the silk proteins make ...
Since early times the sound production by stridulation in spiders has attracted the attention of arachnologists (POCOCK, 1895 a, b) . As in insects, these organs consist of two opposite surfaces which rub one against the other, which are located in several parts of body of the spider (UETZ & STRATTON, 1982). LEGENDRE (1963) attributed to Westring (1843) the first description of a feature with such probable function in Theridiidae, but the first audible sound was reported for spider by WOOD-MASON (1876) for the Indian theraphosid Chilobrachys stridulans (Wood-Mason, 1875). Up to now, several features were described and classified in tarantulas as stridulatory organs (for revisions see CHRYSANTHUS, 1953; LEGENDRE, 1963; UETZ & STRATTON, 1982). In fact, these organs were widely used in the systematics of Theraphosidae (POCOCK, 1895 a, b, 1897, 1899; SIMON, 1903; PÉREZ-MILES et al., 1996; SCHMIDT, 1999, 2000). The tarantulas present high diversity of such features among the spiders, but the ...

In truth, spiders are not intentionally harmful to humans. Most spider bites occur when humans accidentally trap or brush up against a spider and receive a defensive bite. On rare occasions, spiders may have a serious lapse in judgment and bite a human finger (or other body part) mistaking it for a caterpillar or other such prey. Even then, most spiders are too small and not capable of breaking the skin with their fangs, or their venom too weak to be dangerous to humans. Simply put - most spider bites are accidental, harmless and require no specific treatment.. Still, that is not enough to stop spiders from having a bad reputation. It is common for any unexplained skin irritation to be called a spider bite. In fact, most skin lesions and symptoms that are attributed to spiders are rarely actually due to a spider bite. Research has shown that 80 percent of presumed spider bites are actually bites from other insects, or due to skin infections such as MRSA (a resistant staph infection).. Yet, ...
The pathophysiology of a spider bite is due to the effect of its venom. A spider envenomation occurs whenever a spider injects venom into the skin. Not all spider bites inject venom - a dry bite, and the amount of venom injected can vary based on the type of spider and the circumstances of the encounter. The mechanical injury from a spider bite is not a serious concern for humans. Some spider bites do leave a large enough wound that infection may be a concern. However, it is generally the toxicity of spider venom that poses the most risk to human beings; several spiders are known to have venom that can cause injury to humans in the amounts that a spider will typically inject when biting. Only a small percentage of species have bites that pose a danger to people. Many spiders do not have mouthparts capable of penetrating human skin. While venoms are by definition toxic substances, most spiders do not have venom that is toxic to humans (in the quantities delivered) to require medical attention. Of ...
Related narrative: Brown Recluse Spider Bite. Ten thousand spider bites are reported in the United States yearly. Most spiders produce venom which incapacitates prey and is not a defensive mechanism. Human envenomation is usually an incidental result of disturbing the spider. Few spiders have fangs robust enough to penetrate human skin or venom toxic enough to cause necrosis. The common names of the 7 spider families endemic to the US that are a potential threat to humans are the brown recluse/fiddle back, hobo, wolf, fishing, green lynx, running and jumping spiders. Only the first two have venom potent enough to cause death in humans. Black widow bites cause erythema and edema, but not skin necrosis.. Spider bite is rarely suspected as the cause of lesions; it is even more unusual that the spider brought in for positive identification. Spider bites are most commonly single and on an extremity (95%) in one series. Confidence in the diagnosis is graded as putative, presumptive, probable or ...
Sometimes, in the middle of the camping night with friends or relatives, you start feeling itching and notice redness on your leg, arm, or face. The first guess - an insect bit you. But what kind? If it was a big annoying mosquito then nothing is wrong. But what if your peaceful trips destroyer was a brown recluse spider or some of his more dangerous and poisonous friends? In this case, you need to learn how to distinguish the bad spider bites in order to seek a medical assistance for preventing the serious health dangers. What is a spider bite? Before treating a spider bite or arachnidism (as doctors call it) results from the bite of a spider. No surprises, so far. However, there are more than 40.000 different spider kinds in the United States and that is the catch. Almost all types of spiders have fangs and venom but only a few dozens of them can poison an adult human being to death. The nastiest spider types you need to avoid are the brown recluse, hobo, camel spiders and black widow. The first
According to the crypsis hypothesis, the ability of female crab spiders to change body colour and match the colour of flowers has been selected because flower visitors are less likely to detect spiders that match the colour of the flowers used as hunting platform. However, recent findings suggest that spider crypsis plays a minor role in predator detection and some studies even showed that pollinators can become attracted to flowers harbouring Australian crab spider when the UV contrast between spider and flower increases. Here we studied the response of Apis mellifera honeybees to the presence of white or yellow Thomisus spectabilis Australian crab spiders sitting on Bidens alba inflorescences and also the response of honeybees to crab spiders that we made easily detectable painting blue their forelimbs or abdomen. To account for the visual systems of crab spiders prey, we measured the reflectance properties of the spiders and inflorescences used for the experiments. We found that honeybees ...

Spider Bites in Children Facts about spider bites: Most of the 20,000 species of spiders found in the United States are poisonous, but their fangs are too short or too fragile to break through human skin. The bites of most spiders cause only minor, local reactions, although a deadly reaction can occur. In the United States, the two spiders that can cause serious problems are the black widow and the brown recluse spiders (sometimes called the violin spider). Both of these spiders are found in warm climat...

1. Agonistic display among adult male Schizocosa crassipes (Walckenaer), the brush-legged wolf spider, was described. These stereotyped displays are observed exclusively during male-male encounters. 2. The presence of conspicuous black tibial brushes on the males' forelegs, coupled with movements and/or postures of the forelegs, suggests a visually-mediated communication system. 3. R-type factor analysis of the agonistic behaviors treated as variables resulted in four factors which accounted for 74.3% of the variance. These factors were interpreted as

Two major hurdles face the production of recombinant spider silk protein (rSSp) based materials. First, the production of sufficient quantities of rSSp has proven difficult due to their highly repetitive nature and protein size (|250kDa). Secondly, rSSp and native silks are practically insoluble in water based solutions, necessitating the use of harsh organic solvents that can remain in the material after production. While others are working on solving production problems, this dissertation demonstrates a novel aqueous solubilization method that is rapid (|1|minute) and results in near 100% solubilization of the rSSp. From this new solubilization method films, foams, gels (hydrogels and lyogels), adhesives, coatings and fibers have been produced as well as the previously unreported sponge. All of these novel materials were derived from entirely aqueous solutions with and without minor additives to influence the final physical state of the rSSp.

Black Widow Spider venoms contain toxins that attack our nervous system (neurotoxins), usually by interfering with nerve impulse transmission, so disrupting many of the bodys functions. In extreme cases, this can result in death due to respiratory or circulatory failure.. The widow spiders characteristically spins tangled webs, which look similar to spun cotton candy. Their webs are usually built in or beneath objects close to the ground such as under porches, under foundations of buildings, the lose bark of trees, and in basements. The bite of the black widow is painful and may cause death if medical attention is not sought immediately. Venom. The venom of this spider is highly neurotoxic and respiratory failure can occur if appropriate medications are not administered at once. Fortunately, the black widow is shy and does not bite without great provocation. The spider normally resides in an coarse, irregular web. The adult female spider will bite if she feels her young are in danger. If bitten ...
A new study published in the journal Functional Ecology demonstrates that low-level exposure to organophosphate insecticides can alter the individual behavior of jumping spiders, an important beneficial predator in agricultural systems. Young jumping spiders were collected from orchards and raised in the laboratory. Spiders behaviors including hunting ability were quantified before and after exposure to the organophosphate insecticide phosmet. Repeatability or the consistency of behavior in a particular scenario for individual spiders was also measured for spiders exposed to the insecticide and those that were not. While exposure to low levels of the insecticide did not change the average behavior between spiders that were exposed and the control group, there was a significant change in the behavior of individual spiders after exposure, with repeatability decreasing by 23% and different behavioral traits altered between male and female spiders.. ...
What Causes Spider and Varicose Veins?. Spider veins and varicose veins are generally not considered a serious health issue but there are good reasons to try and avoid them. Asides from the fact that they can be indications of underlying venous disease, spider and varicose veins are generally unsightly.. Varicose veins are larger and generally develop in the legs while spider veins are smaller and typically visible on the leg and in the face. But what cases these two similar problems? There are a number of factors that predisposes humans to spider and varicose veins and we will discuss the notable ones briefly.. Heredity Spider and varicose veins have been found to be hereditary in nature. If you have ever had any issue that required vein surgery or have a family history of varicose veins and/or blood clots, there are chances that you will develop spider or varicose veins in the future.. Obesity Obesity has also been linked to spider and varicose veins. If you are currently overweight or obese, ...
So far the largest sequence information could be obtained for flagelliform silk from Nephila clavipes (Figure 2B). This flagelliform silk protein is translated from a ~15.5 kb mRNA transcript originating from a 30 kb Flag locus [9, 23]. The coding sequence is divided into 13 exons. The NR amino-terminal region is split between exons 1 and 2. All of the other exons are found to encode exactly one repeating unit, built from the described motifs (Figure 2B). The final exon 13 in addition includes the NR carboxyl-terminal region.. On the basis of several studies, the major categories of peptide motifs in spider silk proteins have been assigned structural roles [24-28]. The GPGXX motif has been suggested to be involved in a β-turn spiral, probably providing elasticity, based on structures of comparable proteins [29-32]. If elasticity is due to GPGXX β-spirals, then this motif should be found in the more elastic silks. Flagelliform silks, which show the highest elasticity with more than 200 %, ...
Discussion. Our study demonstrates three patterns of clinical effects after definite bites by white-tail spiders (L. cylindrata or L. murina), but no necrotic ulcers. The circumstances of bites were characteristic, with most being in the warmer months in southern Australia, indoors, in the evening and at night.. Considerable mythology has arisen in Australia and around the world regarding spider bites,3,18 related to attribution of clinical effects without confirmation of bite or spider identification. No previous study has both followed up patients and had spiders expertly identified.. For studies of spider bites it is imperative that there is a clear history of a bite, which will almost universally be indicated by pain or discomfort at the time.13 The spider must be collected immediately at the time of the bite, and identification must be by an expert because misidentification is not uncommon, particularly by healthcare workers.19 Without this unbroken chain of causality, clinical effects ...

SNS 217 Spider Mite Control 32 oz SNS 217 Spider Mite Control 32 oz (SNS217-32 oz) SNS-217 Spider Mite Control is made up of 100% pure Rosemary botanical extracts. The botanicals are all food grade GRAS (generally recognized as safe) materials. How It Works Spider mites destroy plant cells by sucking out their contents and SNS-217 s unique formula works by providing a barrier which is harmless to the plant, but fatal to the mites. The natural salts from fatty acids derived from Rosemary extracts disrupt the insect cell structure and permeability of its membranes. Cell contents then leak from damaged cells and the spider mites quickly die Some of the components of SNS-217 are also absorbed by the plant and then suppress the life cycle of the mites. SNS-217 Spider Mite Control kills the spider mite eggs as well by coating the eggs with a oily shield that disrupts the respiration to the egg; therefore no hatching will occur, they will just dry out. Our Product has been tested in our lab on delicate new

Spiders and Harvestmen. Spiders and harvestmen belong to the group (class) of invertebrates, collectively known as the Arachnida, which comprises eleven orders, of which there are four native to the UK and Yorkshire. These are the mites and ticks (Acari), false-scorpions (Pseudoscorpiones), spiders (Araneae) and harvestmen (Opiliones).. The recorders have a particular interest in, and are capable of identifying spiders and harvestmen. The former can be distinguished from harvestmen in having two obvious body segments: the cephalothorax (head) and abdomen, whilst harvestmen have a single body part. Furthermore, harvestmen have two eyes, normally raised on an ocularium (turret) which can be furnished with spines. Spiders, either have six, or more normally, eight eyes. Both of course, have eight legs.. Nationally, there are approximately 650 species of spider and 26 species of harvestmen.. For anyone interested in finding out more information on this diverse and interesting group, please visit ...
Most spider bites are not lethal to adults, but they can cause a certain amount of pain or discomfort. Infants, elderly people, and people with allergies may experience more serious side effects from spider bites. The two most poisonous spiders are the Black Widow and the Brown Recluse. Less than 5% of bites by these spiders are fatal, but it is best to see a doctor if you think you have been bitten by one.
Utahs largest non-tarantula spiders, Carolina wolf spiders are aggressive insect hunters. They are great at blending in with their environment and holding still to avoid detection. The best time to spot them is at night. Their eyes shine like stars when you shine an LED light on them. With this technique, you can spot this spider at 30 feet.. The female Carolina wolf spider is a caring mother. Shell carry an eggsac for weeks until the spiderlings hatch. If the egg sac is removed, shell carry a similar-sized object in its place. When the spiderlings emerge from the egg sac, they climb on her back and ride around for a week or so. Then they scamper off to live their own lives. Photo courtesy of Bryan Doty ...
During anesthesia, debris of skin lesions was removed. Topic treatment was initiated with triclosan antiseptic soap associated with systemic antibiotic therapy with cefalexin (30 mg/kg orally, twice per day). The possible necessity of a plastic surgical repair of the lesions was explained to the owner, but there was complete skin recovery in approximately two months.. After the owner returned home, he reported the presence of a brown spider where the animal remained most of the time. Since he brought the spider to the hospital, it was possible to confirm that it was a Loxosceles spider. However, the animal was in bad conditions of preservation, thus it was not possible to determine its species or to photograph it.. DISCUSSION Several epidemiologic advise about the prevalence of Loxosceles spiders in south and southeast regions of Brazil, including São Paulo (where this case occurred), Paraná (especially near the capital, Curitiba), Santa Catarina and Rio Grande do Sul (13, 20-22). The animal ...
Unlike many other species, male hunting spiders do not use chemical signals such as sex pheromones to attract a mate. Instead, they make their mark by uniquely exploiting a female hunting spiders interest in food. Research led by Cristina Tuni of the Ludwig Maximilian University in Munich in Germany now shows that male hunting spiders wrap morsels of food in their silk and offer these as gifts to prospective mates. The study is published in Springers journal Behavioural Ecology and Sociobiology.. Many previous studies have examined the role that sex-specific pheromones or semiochemicals play in the evolution of a spiders reproduction cycle. Pheromones can be emitted both from a spiders body and from its silk. This form of chemical messaging allows for long-distance air-borne, or direct communication between spiders, and enables them to locate a mate, distinguish between males and females, or decide on the suitability of a potential partner. Among web-building species, females living on webs ...
Common spider bites in florida - How common is it for somebody to have problems from spider bites? Not common..... But, there are some dangerous spiders out there.

When choosing a spider vein treatment, it is important to visit a comprehensive vein specialist who can assess the extent of your vein disease. The most common spider vein treatments are sclerotherapy and to a lesser extent, surface (non-surgical) laser treatment. Sclerotherapy involves the injection (directly into the spider vein) of a chemical solution that will close the offending vein, causing it to disintegrate. If underlying venous disease is present, other vein treatment methods may need to be employed.

But then again, maybe some researchers in the future can come up with proof in the future that will convince the medical community that the white tailed spider is guilty beyond reasonable doubt. Eh?.

The name Trogloraptor actually means cave robber, which is a fitting title. This spider is quite nervous and does not like the light very much. It is thought the claws on its legs are used to grab prey that happens to pass below the spider as it hangs in wait in a dark cave environment. Researchers have yet to figure out what its preferred prey is, but they suspect small flies form a regular meal. However, all Trogloraptors raised in captivity have so far died from starvation having rejected a wide variety of common insects.. The good news is, a shy spider that lives in caves and hates the light should pose no threat to the arachnophobes among us.. Read more at Scientific American and Wikipedia ...
A corrosion-resistant spinneret, suitable for spinning filaments of poly(p-phenylene terephthalamide) from a viscous solution of the polymer in 98-100 percent sulfuric acid, is prepared from a plate of tantalum alloy or stainless steel which is clad on one face with a layer of pure tantalum. A spinneret blank is formed, counterbores are drilled through the plate and partially into the tantalum layer, the blank is annealed, spinneret capillaries are formed from the counterbores through the tantalum layer to the exit face of the spinneret, the face is polished to remove protrusions, and the face is hardened by heat-treatment in nitrogen. Uniform capillaries having a diameter of about 0.002 inch (0.05 mm) and a length greater than about 0.005 inch (0.13 mm) can be formed in spinnerets without breaking tools used in their production.

The black widow spider is notoriously known to many since childhood. The males are harmless and generally smaller than the females. Males do not carry the red hour-glass shape alerting folks of the danger venomous female black widow spiders possess. Generally, black widow spiders are not aggressive, and will only bite if they have no escape and feel threatened. Not only do the females carry the distinctive red or sometimes yellow or orange hourglass shape, but they appear to be a shiny black color. The females abdomen is also rounder than the males. The black widow generally constructs her sleek and durable web, which typically measures a foot wide, in dark garages, old sheds and other structures, or other undisturbed places. If they should stick to the outdoors, you can find her nestling in abandoned animal burrows, in stumps, or behind or within woodpiles. If you are bitten by a black widow you can expect excruciating pain, swelling, redness, abdominal discomfort, headaches and sweating. ...
Spider veins and varicose veins are sometimes viewed as being unsightly and can cause some people to feel self-conscious about their appearance or even look down on themselves. Unfortunately, the effects of these conditions go beyond emotions. If you have spider veins or varicose veins (or both), you have to realize that they can lead to medical problems if you leave them untreated.. Spider Veins. Spider veins are thin, fine lines that are red or purple in color and appear just beneath the surface of the skin of your legs. Theyre not a serious medical condition, but they can cause discomfort in certain situations. They can cause you to feel a burning sensation and cause your skin to be itchy, giving you the urge to scratch it constantly. Depending on their location and your skin type, they can also be prone to bleeding, particularly when you shave your legs. Of course, if you leave them untreated, they can increase in number and become more prominent and noticeable.. Spider veins can exist on ...
You dont know when it happened, but you have blue webs running across your legs. Spider veins are popping up. These veins might be a nuisance, but you can get rid of them with a relatively simple procedure known as sclerotherapy. This spider vein treatment can help you to stop being self-conscious about your legs once again.. How Does Sclerotherapy Work?. Sclerotherapy is a common procedure that is used to treat spider veins. When you have these vein problems, valves in the veins are not doing their job. They are supposed to close after the blood passes through on the way to the heart. When you have faulty valves, they fail to close. Blood can pool in the vein as a result. In the beginning, you may only have spider veins. Over time, they will become more pronounced. To eliminate the problem, sclerotherapy is effective. A special solution will be injected into your spider vein to cause the vein to collapse and seal. In the end, blood can no longer pass through the treated vein. Your body is ...

Thats right - you can permanently treat varicose and spider veins quickly, safely, and with little to no pain.. When it comes to getting rid of varicose and spider veins for good, there are two non-surgical options in particular that provide the best results.. ...

The leukocyte migration induced by Phoneutria nigriventer spider venom (PNV) has been investigated in rats using the pleurisy model. Intrapleural injection of PNV (10-100 mug/cavity) caused a dose- and time-dependent leukocyte accumulation. the bradykinin B-2 receptor antagonist Hoe 140 (0.5 mg/kg) substantially inhibited PNV-induced cell accumulation, whereas the angiotensin-converting enzyme inhibitor captopril (2 mg/kg) potentiated by 80% this effect. the non-specific kallikrein inhibitor aprotinin and the plasma kallikrein inhibitor soybean trypsin inhibitor greatly reduced PNV-induced leukocyte migration, whereas the selective tissue kallikrein inhibitor P-ac-F-S-R-EDDnp failed to affect PNV-induced responses. Treatment of rats with capsaicin (50 mg/kg) at the neonatal stage resulted in 67% inhibition of the PNV-induced cell migration. the neurokinin NK1 receptor antagonist SR140333, but not the NK2 receptor antagonist SR48968, reduced by 55% venom-induced cell accumulation. We conclude ...
While working to improve a tool that measures the pushes and pulls sensed by proteins in living cells, biophysicists at Johns Hopkins say theyve discovered one reason spiders silk is so elastic: Pieces of the silks protein threads act like supersprings, stretching to five times their initial length. The investigators say the tool will shed light on many biological events, including the shifting forces between cells during cancer metastasis.
Famed artist, Louise Bourgeois, clearly had an interesting relationship with her mother. Her new installation at the Tate Modern, Maman (1999) is a giant 30ft sculpture made of bronze, steel and marble and was intended as an ode to my mother according to Bourgeois. Inside of the spiders immense cage-like body, lies a clutch of eggs. While the Tate describes it is a strong and warm representation of motherhood, A female spider, this spectacular arachnid alludes to the strength of the mother with metaphors of spinning, weaving, nuture and protection, the Guggenheim Bilbao, where the piece was previously exhibited states that The spider, provokes awe and fear. They go on to also suggest it represents weakness [Mamans] massive height, improbably balanced on slender legs, conveys an almost poignant vulnerability. Zooillogix offers its own interpretation, and mind you, it is just one interpretation. In our mind, the giant spider ode probably indicates that the artists mother mated with ...
It was the initial impression by those who were with the patient, as well as the EMTs, she was experiencing an anaphylactic reaction to a spider bite. Although it is true, the most common allergens causing systemic anaphylactic reactions include drugs, peanuts, tree nuts, insect venoms, foods, radiocontrast media, allergen immunotherapy injections, and latex. In addition, Hymenopteran (winged insects, such as sawflies, wasps, bees and ants) stings alone are responsible for most arthropod related deaths and usually result from the development of hypersensitivity following repeated exposure to venom. The question that needs to be asked is what types of reactions do spider bites in North America cause. Spiders belong to the order Araneae, which are airbreathing arthropods that have eight legs and chelicerae with fangs that inject venom. There are two spiders of immediate concern in North America, The black widow spider, Latrodectus mactans, and the brown recluse spider, the most famous of which is ...

  • Like arrow-shaped micrathenas, the Australian spiders are "sit-and-wait" predators that ensnare prey in large webs. (
  • Black widow spiders spin their webs outdoors in secluded areas and generally live under rocks, fallen trees, woodpiles, basements, and crawlspaces . (
  • To quantify the rate in which prey can escape the web, we will allow spiders to build webs on a standard substrate, and then remove them from the web. (
  • We will program 'virtual webs' in which simulated spiders can respond to simulated prey hits (with parameters based on the lab study above). (
  • They are lightweight, almost invisible, highly extensible and strong, and of course biodegradable: the threads spiders use to build their webs. (
  • Day 3: Why Do Spiders Spin Webs? (
  • Day 4: Do All Spiders Spin Webs? (
  • Instead of making webs to catch prey, wolf spiders are solitary hunters that depend on their terrific eyesight to hunt their prey at night. (
  • Silk is used by spiders to make webs, construct egg sacs, line nests, wrap captured prey, or construct "balloons" with which to travel on air currents over large distances. (
  • While it is true that spiders will rush across their webs to investigate a vibration, this is just a natural hunting reaction to disturbance and should not be interpreted as aggressive behavior. (
  • According to Sewlal, these arachnids "are called wandering spiders because they do not build webs but wander on the forest floor at night, actively hunting prey. (
  • We see other native spider in the vicinity of the Joro webs, even built on the edge of the webs," he says. (
  • spider webs can clog a fuel vapour vent hose in some 2010 to 2013 Kizashi cars, cutting off air flow. (
  • Thousands of spiders are spinning webs across parts of Australia that are dealing with severe flooding. (
  • Keep in mind, all spiders do not use webs. (
  • Spiders such as the wolf spider and the jumping spider have no use for webs. (
  • Wolf spiders are a common spider that are notable for not spinning webs. (
  • It is slightly erratic in appearance and made with stronger silk than most other spider webs. (
  • Of the 50,000 known spider species, just one or two hunt as a group, with thousands of individuals spread across webs that can span several cubic metres. (
  • To better understand how this works, researchers led by Raphaël Jeanson at the University of Toulouse, France, disturbed the webs of two colonies of Anelosimus eximius, a social spider species. (
  • They mimicked the movement of prey by creating vibrations in different parts of the webs, while filming the spiders' movements. (
  • The webs of these social spiders aren't sticky, so the spiders have to act quickly to avoid their prey escaping. (
  • I tried to just use melted marshmallow for the webs but found that it was much easier to make the spider webs with a bit of water mixed with the melted marshmallow. (
  • A technique is proposed for individually marking orb-web spiders aiming at facilitating the identification of the individuals on their webs. (
  • Bright colors on the Micrathena sagittata likely help the spider attract prey while the outer spikes serve as a defense mechanism. (
  • Scientists believe this may help the spider prey on insects. (
  • A 2002 study published in the journal Ecological Entomology studied a similarly colored black and yellow Australian spider and found that its bright abdomen may help attract prey. (
  • The spiders whose colors had been thus muted were on average less successful at catching prey. (
  • Spiders are hunters, and they often use their fangs to take down their prey. (
  • Most spiders have venom to subdue their prey, but they only use it against humans if disturbed. (
  • Normally, spiders only use their chelicerae to inject venom into prey. (
  • Brief Description) Ecologically, spiders are both predators and prey. (
  • Predicting and testing effects of rhythmicity in spider behavior on prey capture within a cooperative web. (
  • This will allow us to estimate how much time after prey hits the web the spiders have to subdue it. (
  • With this system, we can test the effects of different spacing patterns (i.e. clumped, random, or uniform) and different densities of spiders on the likelihood of prey detection and time to intercept. (
  • These water spiders catch their prey by anchoring their hind legs on a stone or plant and placing their front legs on the surface, "ready to ambush," the researchers say. (
  • Spiders have a pair of hollow, fanglike mouthparts and venom-producing glands that they use to subdue their prey. (
  • Not all spiders catch their prey in the same way. (
  • All spiders, with the exception of one species, use venom to paralyze their prey. (
  • Because a spider cannot ingest solid foods, it excretes a digestive enzyme into its paralyzed prey. (
  • Many spiders learn and adapt to the habits of their prey to make catching them easy. (
  • Most spiders feed on other invertebrates, while other very large spiders prey on animals such as birds. (
  • The researchers studied spider response to a simulated predator and also prey attack response (to vibration). (
  • Instead, they hunt their prey with the help of excellent eyesight, which is unusual for spiders. (
  • Spiders use silk to catch prey and to anchor themselves against falling. (
  • Crab spiders capture prey by sitting and waiting for an insect or other spider to pass by. (
  • Sea spiders feed by grabbing prey with their mouthparts. (
  • Spiders that hunt in packs use web vibrations to coordinate their attacks, allowing them to kill prey hundreds of times larger than they could on their own. (
  • When prey insects land on their web, the spiders synchronise their attack, moving as one to catch animals up to 700 times heavier than an individual arachnid. (
  • Jeanson and his team then analysed the movements frame by frame, finding that the spiders pause their motion towards prey, and restart it, at the same time. (
  • The arachnids only stayed still for as long as they had to in order to distinguish the vibrations caused by their fellow spiders from those of their prey. (
  • Depending on the size of the prey - and the vibrations that the prey creates on the web - the spiders have to be more or less quiet and still in order to localise the prey without getting disturbed by the vibrations of other spiders that are moving around," he says. (
  • The spiders also synchronise when they eject an immobilising glue from their hind legs and bite their prey, injecting a venom. (
  • Say you're treating a patient with a fear of spiders. (
  • Some researchers attribute fear of spiders to an evolutionary survival instinct. (
  • Arachnophobia refers to the intense fear of spiders, or spider phobia. (
  • Both the intense fear of spiders and spiderwebs are types of specific phobias. (
  • So, in the case of arachnophobia, it's possible to have a debilitating fear of spiders due to a negative encounter with these arthropods. (
  • If you grew up with parents or other loved ones who had an intense fear of spiders, you may be at an increased risk of developing the same fears. (
  • It's also possible to experience fewer symptoms of arachnophobia as an adult if your intense fear of spiders affected you as a child. (
  • And bites by the venomous black widow and brown recluse spiders can be very dangerous to people. (
  • What do black widow and brown recluse spiders look like? (
  • Immature brown recluse spiders closely resemble the adults except for their smaller size and slightly lighter color. (
  • What are the life cycles of the black widow and the brown recluse spiders? (
  • Similar to black widow spiders, development of brown recluse spiders depends on availability of food and environmental temperature and may take from 10-12 months. (
  • Where can I find the black widow and the brown recluse spiders? (
  • However, brown recluse spiders have a distinct violin-shaped marking on their heads. (
  • The other common venomous spider is the black widow, but these are distinct from both wolf spiders and brown recluse spiders. (
  • Spiders are usually not aggressive and most bites occur because a spider is trapped or unintentionally contacted. (
  • It is important for employers to educate their workers about their risk of exposure to venomous spiders, how they can prevent and protect themselves from spider bites, and what they should do if they are bitten. (
  • Most spider bites are harmless. (
  • Occasionally, spider bites can cause allergic reactions. (
  • Spider Bites: How Dangerous Are They? (
  • What Do Spider Bites Look Like? (
  • How can you identify spider bites? (
  • Common spider bites look like any other insect bite. (
  • In North America, though, there are two other spiders whose venomous bites can be much more serious--even deadly in some rare cases. (
  • You'll learn more about these two spiders later, and what to do if one bites you. (
  • What are the symptoms of spider bites? (
  • In Africa, hundreds of thousands of years ago, our ancestors lived alongside several species of venomous spiders, whose bites, even if not fatal, could incapacitate an individual for days or weeks. (
  • Wolf spider bites are not dangerous and do not usually require specific medical attention. (
  • In rare instances, a person may be allergic to spider bites. (
  • In this article, we take a look at how people can identify a wolf spider and what might happen if a spider bites them. (
  • Bites from a wolf spider and other insects are very similar, so unless a person actually sees the wolf spider biting them, they may never identify the culprit. (
  • As an article in the journal Critical Care Nursing Clinics of North America notes, spider bites may seem alarming, but in reality, they pose a minor risk. (
  • In general, wolf spider bites are rare, and people do not need to be too concerned. (
  • The vast majority of wolf spider bites do not require medical attention. (
  • Although spider bites are common in many parts of the United States, most domestic spiders are not substantially venomous to man. (
  • In 1994, poison-control center log reports compiled by the American Association of Poison Control Centers listed 9418 spider bites ( Table 1 ) (1). (
  • The majority of spiders are harmless, although some species can be regarded as moderately harmful since their bites can lead to quite severe local symptoms. (
  • Spiders belong to the order Araneae of the class Arachnida. (
  • The spider genus Loxosceles in North America, Central America, and the West Indies (Araneae, Loxoscelidae). (
  • Spiders (order Araneae) are air-breathing chelicerate arthropods that have eight legs, and chelicerae modified into fangs that inject venom. (
  • Neuroptera: Chrysopidae), spiders (Araneae), and Zelus armillatus (Lep. (
  • Spiders are Arachnids, a group that also contains mites, ticks and scorpions. (
  • Spiders are arachnids. (
  • While it's not uncommon for people to dislike arachnids or insects, phobias of spiders can have a far more significant impact on your life. (
  • Except for mites and ticks, spiders constitute the largest order of arachnids, with approximately 37,000 species having been described. (
  • While this trip to Honduras was the first time the amphibian specialist has seen this spider species, arrow-shaped micrathenas can actually be found throughout North America and are even widespread in the U.S. They can be hard to spot though-these spiders are small. (
  • But unlike spider species in which the female kills the male,the male fishing spider appears to expire from internal causes. (
  • Trapdoor spiders are reluctant travellers, but millions of years ago one species appears to have made an epic journey from Africa across the vast Indian Ocean to call Australia home. (
  • There are roughly 40,000 different spider species around the world. (
  • They have also observed species in three more spider families catching fish in a lab. (
  • Wolf spiders may be tough hunters, but they're not without predators, including some species of hunting wasps. (
  • Spiders generally live for only one or two years, but a few species can live as long as 5 to 20 years. (
  • Phoneutria nigriventer, a species of Brazilian wandering spider, in an "armadeira" threat display. (
  • There are nine species of Brazilian wandering spider, all of which are nocturnal and can be found in Brazil. (
  • Research into one species of Brazilian wandering spider, Phoneutria boliviensis , revealed that these spiders eat a mix of arthropods and reptiles. (
  • So far, they seem to be able to coexist with other orb-weaving spider species and don't seem to have affected larger animals. (
  • The Tooth Cave spider is a very small, slender spider species. (
  • Conservation efforts are underway to protect the habitat of the Tooth Cave spider and other endangered species . (
  • As with many animal species, the female spider is almost always than their male counterparts. (
  • Many spider species have elaborate dances and rituals that they follow before approaching a female to get her permission before getting too close. (
  • There are about 40,000 different species of spider that live in every part of the world except Antarctica. (
  • Scientists have identified more than 1,000 species (kinds) of sea spiders, but many more probably remain undiscovered. (
  • Though, I'm not sure if I can pick a favorite spider species-wise or whatever. (
  • If I were to pick a species, I think I might have to go with Wolf Spiders. (
  • Wolf spiders live mostly in forests, grasslands and woodlands and can easily be found in people's backyards. (
  • Some of the more common groups include orb weavers, crab spiders, jumping spiders and wolf spiders. (
  • Some wolf spiders will live in and defend burrows while others may roam around looking for food. (
  • Like many spiders, wolf spiders tend to avoid people but will live in and around basements, lofts, sheds, and garages. (
  • Wolf spiders are fairly large, ranging from 0.5 to 2 inches long. (
  • Wolf spiders have eight eyes, two of which are particularly large. (
  • People can sometimes confuse wolf spiders with the brown recluse spider, which is a more dangerous venomous spider. (
  • Wolf spiders seek to avoid human contact and will only bite if provoked. (
  • Wolf spiders are solitary. (
  • People should also be wary around piles of leaves, as some wolf spiders use these as a home. (
  • Wolf spiders will usually only bite people if they come into direct contact with them and feel threatened. (
  • Being careful around areas where wolf spiders might be living will reduce the risk of being bitten. (
  • Baby wolf spiders are insanely adorable and heplless. (
  • Wolf Spiders it is. (
  • Though many people are afraid of spiders, they rarely bite people unless threatened. (
  • Even the spiders that are potentially harmful are unlikely to bite unless they think their lives are in danger. (
  • You may worry that a black widow spider bite will kill you, but can it? (
  • This helps prevent infection and the development of further black widow spider bite stages. (
  • Spiders rarely bite humans. (
  • People tend to fear spiders because they believe that spiders are aggressive and seek to bite humans. (
  • What does a wolf spider bite look like? (
  • In general, a person can treat a wolf spider bite in the same way as they would treat any other minor insect bite. (
  • We also examine the treatment options available for dealing with a spider bite. (
  • Generally, a wolf spider bite is not dangerous. (
  • In the vast majority of cases, a person bitten by a wolf spider will react in the same way they would from a bite by other minor insects. (
  • But unlike Sony's movies, Marvel's Spider-Man franchise never showed how Tom Holland's Peter got that spider bite. (
  • Unfortunately, the bite of a black widow spider can be very painful and even deadly, which makes them a dangerous pest and not a creature you want around your home. (
  • Is it a spider bite? (
  • An eschar on her leg was consistent with necrosis from a spider bite. (
  • By using augmented reality as means of conducting exposure therapy, STARC researchers - including Shantanu Madaboosi, Rakesh Ramaswamy, and Lana Grasser - and STARC director Arash Javanbakht, MD , have produced compelling evidence that they can free patients of their often debilitating fears of spiders, dogs, and snakes. (
  • But the problem we had is that if someone comes to me and says they're afraid of dogs, snakes, or spiders, I don't have those in my office. (
  • A common argument suggests we are "evolutionarily programmed" to be afraid of spiders and snakes. (
  • Cultural biases facilitate fear learning, so fears of snakes, spiders, and angry people are more easy to acquire than fears of, say, mushrooms and clowns. (
  • All spiders are predators and should be considered beneficial in this role. (
  • All spiders are hunters, also known as predators. (
  • As polar ice melts, giant sea spiders lose their protection from such predators as birds and marine mammals. (
  • Huntsmen can get up to 10 inches in size, and as much as I love spiders, I'd react if I saw one one the size of a dinner plate too, dead or alive. (
  • That's another reason to love spiders. (
  • A 2019 study on arachnophobia found that patients exposed to positive media interpretations of spiders (in this case, "Spider-Man" movies) decreased their fears. (
  • En décembre 2019, la population de Wuhan, une grande ville chinoise de 11 millions d'habitants, est atteinte par une pneumonie virale extrêmement contagieuse due au coronavirus SARSCoV-2. (
  • It is also the most venomous spider in North America. (
  • The only other spider in North America that poses a medical danger to humans is the brown recluse. (
  • They are the most venomous spiders in North America. (
  • Spider silk is one of the toughest fibres in nature and has astounding properties. (
  • Scientists from the University of Würzburg discovered new molecular details of self-assembly of a spider silk fibre protein. (
  • In fact, spider silk is among the toughest fibres in nature. (
  • Today, it is possible to manufacture artificial spider silk of similar properties as the prototype, but the molecular-level structural details responsible for material properties await to be disclosed. (
  • The silk fibres consist of protein building blocks, so-called spidroins, which are assembled by spiders within their spinning gland," explains Neuweiler. (
  • This two-step process of self-assembly was previously unknown and may contribute to extensibility of spider silk. (
  • It is known that stretching of spider silk is associated with unfolding of helix. (
  • Neuweiler describes the result as "a contribution to our molecular-level understanding of structure, assembly and mechanical properties of spider silk. (
  • It may aid material scientists to reproduce natural spider silk in the laboratory. (
  • Two-step self-assembly of a spider silk molecular clamp, Nature Communications (2018). (
  • Young spiders typically climb to a high point in their surroundings with suitable air currents, spin silk threads into the air and float away like tiny parachutists. (
  • All spiders can spin silk. (
  • Different spiders use their silk for different purposes. (
  • But spiders also use their silk to fly. (
  • The spider releases silk from the end of its abdomen, and the silk increases in length as the spider waits. (
  • When the strand of silk catches enough wind, the spider lets go of its hold and the wind carries it aloft. (
  • When large numbers of spiders balloon at the same time, their silk strands may become entangled and form a large mass. (
  • The first series set in Sony's Spider-Man Universe (SSU) is Silk: Spider Society, developed by The Walking Dead's showrunner, Angela Kang, and Spider-Man: Into the Spider-Verse producers Phil Lord and Christopher Miller. (
  • In addition to the sequel to 'Into the Spider-Verse', Spider-Gwen will team up with two other female heroes, Spider-Woman (Jessica Drew) and Silk (Cindy Moon) in 'Spider-Women', to be written by Bek Smith, with Lauren Montgomery likely to direct. (
  • Using a new mathematical methodology, researchers at MIT have created a scientifically rigorous analogy that shows the similarities between the physical structure of spider silk and the sonic structure of a melody, proving that the structure of each relates to its function in an equivalent way. (
  • The study explains that structural patterns are directly related to the functional properties of lightweight strength in the spider silk and, in the riff, sonic tension that creates an emotional response in the listener. (
  • While likening spider silk to musical composition may appear to be more novelty than breakthrough, the methodology behind it represents a new approach to comparing research findings from disparate scientific fields. (
  • Such analogies could help engineers develop materials that make use of the repeating patterns of simple building blocks found in many biological materials that, like spider silk, are lightweight yet extremely failure-resistant. (
  • The best known exceptions are widow spiders (Latrodectus spp. (
  • The most likely way to experience a serious dose of venom is by squeezing the spider. (
  • Spiders such as the black widow (female only) and the brown recluse (female and male) are equipped with hollow fangs (chelicerae) that inject venom. (
  • Spiders in the Uloboridae family do not have venom glands at all. (
  • The film is out on April 1st, but Sony is dying to link the film to Tom Holland's Spider-Man and to Venom. (
  • Sony had a great year at the box office with Venom: Let There Be Carnage and Spider-Man: No Way Home. (
  • Venom 2's box office haul reached $502 million worldwide, while the latest MCU Spider-Man topped $1.8 billion so far - and the film's theatrical run isn't over. (
  • I mean, putting giant (dead) Huntsman spiders in a room you then invite spider phobic people into seems a bit cruel. (
  • The Giant Huntsman spider has a leg span of 12 inches. (
  • Helen Tanner remembers stealing glimpses of her husband, Philip ("Phil") Robinson, MBChB, PhD, associate professor at the University of Queensland, Australia, catching and rehoming huge Huntsman spiders. (
  • But if you do get bitten by a venomous spider, you will want to prepare yourself. (
  • En Algérie, le premier cas a été identifié le 25 février 2020, un plan de riposte national élaboré par le ministère de la santé a été mis en place pour affronter l'épidémie. (
  • The world spider catalog , version 12.5. (
  • Registration is free, and dedicated forums exist for the discussion of Tarantulas, True Spiders, Centipedes & Scorpions. (
  • The objectives were to evaluate insects and spiders , their ecological indices and interactions on A. mangium saplings in a tropical degraded area in recovering process. (
  • Whether or not an insect is captured or escapes when it hits a web depends on how quickly at least one spider detects it and reaches it. (
  • This particular wolf spider lives in the O. Orkin Insect Zoo at the Smithsonian's National Museum of Natural History. (
  • 7. Don't call a spider an insect! (
  • But the genetic analysis of the Australian trapdoor spider and the African Moggridgea spiders indicates they separated long after the supercontinent of Gondwana split up, but before humans arrived in Australia, which rules out human migration as the trapdoors' means of dispersal. (
  • Are All Spiders Harmful to Humans? (
  • But no spider in the world is large enough to hunt humans for food. (
  • Fleas and mosquitos are more harmful to humans, and they're some spiders' favorite foods. (
  • The black widow spider lives up to its reputation as one of the most dangerous spiders to humans. (
  • Spiders are beneficial to humans because they feed on pest insects in homes and gardens. (
  • Despite what you might see in sci-fi tales, especially this Jeff Daniels movie , most spiders aren't harmful to humans. (
  • While there are many different spiders, most are not dangerous to humans. (
  • Fortunately, sea spiders are too small to threaten humans. (
  • Other scientists say arachnophobia is a learned behavior, due to a childhood trauma or kids observing their parents and siblings getting freaked out by spiders. (
  • Arachnophobia can prevent you from participating in certain events or situations because your mind tells says you're in danger from spiders . (
  • With arachnophobia, you may not experience symptoms until you see a spider. (
  • Evidence shows that many people with arachnophobia overestimate the likelihood of encountering spiders. (
  • While Spider-Man won't necessarily help you cure your arachnophobia, seeing spiders in such a positive context could be a start in the right direction. (

  • The crab spider is one that uses ballooning to get around. (
  • All crab spiders generally resemble crabs: Their legs extend outward from the sides, and they can walk in any direction. (
  • The first pair of legs are large and powerful, as in flower crab spiders, and are covered with many tiny spines. (
  • Crab spiders can be found under bark as well as on the forest floor under leaves, rocks, and on decaying logs. (
  • Woodland crab spiders are not easily seen because of their cryptic coloration but nevertheless are fairly common. (
