This is a collaborative project between the Phenotypic Evolution Lab and the Animal Flight Lab.. Damselflies of the genus Calopteryx are highly aerial creatures that depend on their flight capabilities for hunting, territory defense, courtship displays, mating success and predator avoidance. All these requirements put selective pressure on wing morphology, although potentially in opposing directions. While we have a good conceptual understanding of the consequences of wing shape on flight performance, few studies have shown a direct link between wing morphology, flight performance and individual fitness and survival in the field.. Our study system comprises of two sympatric damselfly species: Calopteryx splendens, and C. virgofor which previous studies suggest differential selection pressure on wing morphology by avian predators. We use geometric morphometric methods to analyze variations in wing morphology, both between and within the species, and combine these data with flight performance ...
Wing sweep differentially influenced aerodynamic performance on a per unit area basis (i.e. CV and CH). During emulated flapping, extended wings outperformed swept wings in both CV and CV:CH, whereas during emulated gliding, swept wings outperformed extended wings in CV and matched performance in CV:CH. These results provide insight into the relationship between wing posture and aerodynamic performance in raptors.. In emulated flapping flight, angular velocity of the rotating wing causes the wing tips to move more quickly than the wing roots. As aerodynamic forces vary with the square of local velocity, longer wings produce exponentially greater forces. Furthermore, local flow conditions (as indicated in the coefficients) likely change according to wing posture, and may influence aerodynamic forces. In flapping flight, extended wings had 23.1% higher CV than swept wings. Thus, in flapping, the 68% increase in peak FV from swept to extended posture is likely driven by the additive positive ...
Type Wings are non-deploying force provider wings which supply combat ready VFA, VAQ, VAW, HSC or HSM squadrons or Fleet Logistics Support (VRC) detachments to Carrier Air Wings, or combat ready VAQ, VP, HM, HSC, HSM squadrons or detachments for expeditionary land based or shipboard (non-aircraft carrier) detachment deployments. Functional Wings operate land based aircraft such as those of Fleet Logistics Support, Patrol and Reconnaissance or Strategic Communications Squadrons.. Type and Functional Wings are not assigned Tail Codes except for the Navy Reserves Tactical Support Wing which retains the code AF from its former existence as Carrier Air Wing Reserve TWENTY and Electronic Attack Wing, U.S. Pacific Fleet (VAQWINGPAC) which adopted the code NL from the disestablished CVW-15 for use by the wings land based expeditionary squadrons only. Type Wing squadrons which deploy as a part of a Carrier Air Wing wear the tail code of that Carrier Air Wing. Type Wing squadrons which do not ...

νgW is a homozygous lethal mutation killing embryos prior to formation of the syncitial blastoderm. In heterozygous condition it causes duplications of the posterior wing, ranging from very small duplications of the axillary cord and alar lobe to large duplications including much of the wing blade and the posterior row of bristles. No anterior margin structures are ever observed. The thorax is sometimes slightly abnormal, but rarely shows large duplications. The size of the wing is related to the number of pattern elements deleted or duplicated.. Heterozygous νgW flies also show homoeosis of the haltere to wing. This occurs in the capitellum, where wing blade is observed, but no wing margin structures are found. As with the bithorax (bx) mutation which transforms anterior haltere to anterior wing this aspect of the phenotype is repressed by the Contrabithorax (Cbx) mutation. The transformed haltere discs show more growth than wild-type haltere discs.. Flies heterozygous for νgW also show a ...
Butterfly wing color patterns emerge as the result of a regular arrangement of scales produced by epithelial scale cells at the pupal stage. These color patterns and scale arrangements are coordinated throughout the wing. However, the mechanism by which the development of scale cells is controlled across the entire wing remains elusive. In the present study, we used pupal wings of the blue pansy butterfly, Junonia orithya, which has distinct eyespots, to examine the possible involvement of Ca2+ waves in wing development. Here, we demonstrate that the developing pupal wing tissue of the blue pansy butterfly displayed spontaneous low-frequency Ca2+ waves in vivo that propagated slowly over long distances. Some waves appeared to be released from the immediate peripheries of the prospective eyespot and discal spot, though it was often difficult to identify the specific origins of these waves. Physical damage, which is known to induce ectopic eyespots, led to the radiation of Ca2+ waves from the immediate
The Drosophila Vestigial protein has been shown to play an essential role in the regulation of cell proliferation and differentiation within the developing wing imaginal disc. Cell-specific expression of vg is controlled by two separate transcriptional enhancers. The boundary enhancer controls expression in cells near the dorsoventral (DV) boundary and is regulated by the Notch signal transduction pathway, while the quadrant enhancer responds to the Decapentaplegic and Wingless morphogen gradients emanating from cells near the anteroposterior (AP) and DV boundaries, respectively. MAD-dependent activation of the vestigial quadrant enhancer results in broad expression throughout the wing pouch but is excluded from cells near the DV boundary. This has previously been thought to be due to direct repression by a signal from the DV boundary; however, we show that this exclusion of quadrant enhancer-dependent expression from the DV boundary is due to the absence of an additional essential activator in ...
Decapentaplegic (Dpp) is one of the best characterized morphogens, required for dorso-ventral patterning of the Drosophila embryo and for anterior-posterior (A/P) patterning of the wing imaginal disc. In the larval wing pouch, the Dpp target gene optomotor-blind (omb) is generally assumed to be expressed in a step function above a certain threshold of Dpp signaling activity. We show that the transcription factor Omb forms, in fact, a symmetrical gradient on both sides of the A/P compartment boundary. Disruptions of the Omb gradient lead to a re-organization of the epithelial cytoskeleton and to a retraction of cells toward the basal membrane suggesting that the Omb gradient is required for correct epithelial morphology. Moreover, by analysing the shape of omb gain- and loss-of-function clones, we find that Omb promotes cell sorting along the A/P axis in a concentration-dependent manner. Our findings show that Omb distribution in the wing imaginal disc is described by a gradient rather than a step

The stable states for loss-of-function or ectopic mutant clones affecting the second signaling process have been computed using constraint programming (see materials and methods). Table 1 gives the stable states for each perturbation considered.. In the simulation of a N− clone in the dorsal (flanking and boundary) cells, the wild-type stable state is lost (mutant 1 in Table 1), in agreement with the margin nicks observed in N− clones abutting the wing margin (de Celis and García-Bellido 1994; Micchelli et al. 1997).. wg− mutant discs and large clones reaching the boundary produce notches of the wing margin (Couso et al. 1994). Simulation of this genotype also results in a mutant phenotype (mutant 2 in Table 1).. Simulation of a ct− mutant disc does not lead to the wild-type stable state, but rather to an ectopic upregulation of the N ligands in boundary cells (mutant 3 in Table 1). This agrees with observations in ct− mutant discs, where there are margin nicks in the wing and ectopic ...
During flapping flight, insect wings accelerate masses of air, generating the forces necessary to support the insects weight and to perform complex maneuvers. At the same time, these ultralight airfoils (generally only 0.5-5% of body mass; Ellington, 1984b) must withstand the forces imposed upon them by the surrounding air, as well as the inertial forces caused by accelerating and decelerating their own mass up to several hundred times per second.. Insect wings perform these roles extremely successfully, despite the fact that they are largely passive structures, with no muscular control past the wing base (Wootton, 1992). Although they are strengthened by a network of tubular veins, the wings of many species deform noticeably during flight, especially during slow flight and hovering (Willmott and Ellington, 1997a). These dynamic changes in the three-dimensional shape of wings could potentially affect many aspects of force production, yet few models of insect flight have successfully ...
Insect wings are outgrowths of the insect exoskeleton. They are found on the second and third thoracic segments (the mesothorax and metathorax), and the two pairs are often referred to as the forewings and hindwings, respectively, though a few winged insects lack hindwings, even rudiments. Insect wings do not constitute appendages in technical parlance, as insect only have one pair of appendages per body segment. The wings are strengthened by a number of longitudinal veins, which often have cross-connections that form closed cells in the membrane (extreme examples include Odonata and Neuroptera). The patterns resulting from the fusion and cross-connection of the wing veins are often diagnostic for different evolutionary lineages and can be used for identification to the family or even genus level in many orders of insects. Fully functional wings are present only in the adult stage, after the last molt. The one exception is the order Ephemeroptera, in which the penultimate instar (also called ...

The wing imaginal disc of Drosophila melanogaster is a prominent experimental system for research on control of cell growth, proliferation and death, as well as on pattern formation and morphogenesis during organogenesis. The precise genetic methodology applicable in this system has facilitated conceptual advances of fundamental importance for developmental biology. Experimental accessibility and versatility would gain further if long term development of wing imaginal discs could be studied also in vitro. For example, culture systems would allow live imaging with maximal temporal and spatial resolution. However, as clearly demonstrated here, standard culture methods result in a rapid cell proliferation arrest within hours of cultivation of dissected wing imaginal discs. Analysis with established markers for cells in S- and M phase, as well as with RGB cell cycle tracker, a novel reporter transgene, revealed that in vitro cultivation interferes with cell cycle progression throughout interphase ...
In this work the numerical simulation of aerodynamic performance of low aspect ratio wings at low Reynolds numbers applicable to micro aerial vehicle is carried out. Commercial software STAR-CCM+ was used to simulate the flow and predict the aerodynamics performances of the low aspect ratio wing. Results were presented in terms of pressure coefficient distribution, flow visualization, lift and drag coefficients for angle of attacks ranging from 0˚ to 18˚ and Reynolds numbers ranging from 104 to 105 Keywords: Rectangular planform wing; Tip vortices; Flow separation . The results showed that, for rectangular planform wing, the distribution of the pressure is dominated by vortices. The results also showed the formation of tip vortices at lower Reynolds number for rectangular wing configuration. It is evident from the results that the type of wing configurations plays a very important role in delaying or preventing the flow separation.. ...

We used the UAS-GAL4 system (Brand and Perrimon, 1993) to drive expression of diβ in the wing. The expression of diβ in the whole wing pouch by using the GAL4 line CY2 (Queenan et al., 1997) produced a blister in the adult wing. Whereas this phenotype strongly resembles that of loss of integrin function, suggesting that expression of diβ in the wing was causing a dominant-negative effect (Fig. 2B), wing blistering may also result from a gain of integrin function (Baker et al., 2002). To confirm whether diβ was indeed inhibiting integrin function, we analysed whether the wing blister observed upon diβ overexpression was sensitive to mutations in the βPS subunit. If diβ was behaving as a dominant negative chimera, then reducing the endogenous integrin activity should enhance the effects of diβ overexpression. Since null mutants of the gene encoding the βPS integrin subunit (myospheroid, mys) are lethal, we used two hypomorphic homozygous viable alleles, mysB43 (Fig. 2A) (Jannuzi et al., ...
FOR every quantitative trait some set of genomic sites can yield mutational variation. The full distribution of potential effects is unknowable, since it is a function of all possible modifications; but any mutational screen can help to identify quantitative trait loci (QTL). Here we report the provisional identification of 11 loci affecting wing shape in Drosophila melanogaster, based on effects produced with high frequency by random P-element insertions.. Wing shape is the third morphological trait in Drosophila to be mapped for natural QTL (Weber et al. 1999), after bristle number (Long et al. 1995) and features of male genitalia (Liu et al. 1996). Studies of natural genetic variation in wing shape in D. melanogaster find evidence of numerous small, mainly additive effects (Weber et al. 1999, 2001), which are largely independent of sex and body size (Weber 1990; Birdsall et al. 2000; Zimmerman et al. 2000) and sometimes act in small regions of the wing (Weber 1992).. Common natural alleles ...
Background Quantitative differences between individuals stem from a combination of genetic and environmental factors, with the heritable variation being shaped by evolutionary forces. Drosophila wing shape has emerged as an attractive system for genetic dissection of multi-dimensional traits. We utilize several experimental genetic methods to validation of the contribution of several polymorphisms in the Epidermal growth factor receptor (Egfr) gene to wing shape and size, that were previously mapped in populations of Drosophila melanogaster from North Carolina (NC) and California (CA). This re-evaluation utilized different genetic testcrosses to generate heterozygous individuals with a variety of genetic backgrounds as well as sampling of new alleles from Kenyan stocks. Results Only one variant, in the Egfr promoter, had replicable effects in all new experiments. However, expanded genotyping of the initial sample of inbred lines rendered the association non-significant in the CA population, ...

Background: Natural environments fluctuate and all organisms experience some degree of environmental variance. Global climate models predict increasing environmental variance in the future. Yet we do not fully understand how environmental variation affects performance traits. Questions: Does temperature fluctuation during development affect adult size and wing shape in Drosophila melanogaster? If so, are the effects predictable? Do they depend on heterozygosity? Do fluctuations in developmental temperature affect adult physiological performance at high temperature? Methods: We tested the effect of one fluctuating (21 degrees C/29 degrees C) and several constant (21 degrees C, 23 degrees C, 25 degrees C, 27 degrees C, 29 degrees C) developmental temperature regimes on three wing morphometric traits (wing length, wing width, and wing shape) in an experiment using three inbred lines of D. melanogaster and their first-generation hybrids. We also tested the effect of fluctuating and constant ...
Boeing. has completed destructive testing on a full-scale composite wing box of the 787 Dreamliner as part of the new commercial aircrafts certification process. Successful completion of the wing box destruction test marks a major step forward in highlighting the innovation on the 787, said Mark Jenks, vice-president of 787 development. In addition to determining the strength of the structure, the test helps us verify the analytical methods we have used to calculate the loads the structure will have to carry. The wing box (pictured below) is a cantilevered beam that carries the wing to the fuselage and supports leading and trailing-edge devices, control surfaces, engines and landing gear. The test piece represents a portion of the wing section that begins at about the centre of the airplane and stops at approximately one-half of the span of the wing, or approximately 15.2m. The piece measures around 5.5m at its widest point. The upper and lower surface panels and the spars of the wing are ...
Wing deformations are a distinctive, and therefore presumably important, characteristic of insect flight. In spite of this, there are few good measurements of how the wings deform during flapping. Detailed quantitative measurements of the local three-dimensional shape of static insect wings reveal an exquisitely complex architecture (e.g. Wootton et al. 2000; Sudo et al. 2005), which is important in determining the aerodynamic properties of the wings under steady conditions (e.g. Rees 1975; Okamoto et al. 1996; Kesel 2000). However, it is not known how such static measurements relate to the shape of the wing in flapping flight, when dynamic structural, muscular, aerodynamic and inertial forces come into play (Combes & Daniel 2001, 2003a,b). At a global level, significant spanwise twist and camber have been observed qualitatively in many insects (e.g. locusts: Jensen 1956, Baker & Cooter 1979, Wortmann & Zarnack 1993; hawkmoths: Willmott & Ellington 1997; butterflies: Wootton 1993; crane flies, ...
The use of twin clones has allowed us to get a detailed insight in how ordered cell proliferation generates the shape and size of the growing wing disk. The interface between the twin clones reveals the topological position of the mother cell of both clones. It follows that for daughter single clones the mother cell is topologically located in its center. Interfaces appear everywhere in the adult wing but with shape, extent, and positions that are wing sector and initiation age specific. Frequencies and position specificities correspond to the developmentally changing location of clusters of cells in the G2 stage of the cell cycle, when the cells are sensitive to induced mitotic recombination (5, 9). Mitotic spindle orientations in the planar axis of the wing epithelium are random, but postmitotic cells allocate preferentially along the x or y axis of the wing blade (24). The shape of interfaces reflects the main orientations of successive clonal cell divisions. The fact that twin clones are of ...
The genetic basis of wing development has been well characterised for model insect species, but remains poorly understood in phylogenetically divergent, non-model taxa. Wing-polymorphic insect species potentially provide ideal systems for unravelling the genetic basis of secondary wing reduction. Stoneflies (Plecoptera) represent an anciently derived insect assemblage for which the genetic basis of wing polymorphism remains unclear. We undertake quantitative RNA-seq of sympatric full-winged versus vestigial-winged nymphs of a widespread wing-dimorphic New Zealand stonefly, Zelandoperla fenestrata, to identify genes potentially involved in wing development and secondary wing loss. Our analysis reveals substantial differential expression of wing-development genes between full-winged versus vestigial-winged stonefly ecotypes. Specifically, of 23 clusters showing significant similarity to Drosophila wing development-related genes and their pea aphid orthologues, nine were significantly upregulated in full

Naomi Pierce and PhD candidate, Richard Childers teamed with researchers at Columbia University to examine the wings of Lepidoptera. Butterfly wings contain a matrix of living cells whose function requires appropriate temperatures. However, given their small thermal capacity, wings can overheat rapidly in the sun. The team analyzed wings across a wide range of simulated environmental conditions and found regions containing living cells are maintained at cooler temperatures.
The focus of this research proposal is the investigation of the aeroelastic effects of a flexible lift augmentation system (LAS) wing. This research involves characterization of the forced vibration response of a wing appendage used to augment short field take off and landing (STOL) operations. Although flutter theory is now well understood, the LAS presents the complications of a highly deformable airfoil shape as well as larger structural damping values compared to metal wings. The proposed research will involve derivation of the equations of motion aided by experimental data from nodal excitation of the wing; stiffness and rigidity modeling from static wing loading and collection of flight test data to characterize the potential flow around the membrane wing. The knowledge gained from this research will be of critical importance in assuring the safety of flight by identifying the critical flutter speeds, as well as establishing a good basis for the structural design of future lift augmentation

When making hot wings, I like to deviate in two distinct ways from the standard way of cooking the wings. After seasoning the wings with salt, pepper, onion powder, garlic powder, and paprika, I line them on a baking rack over a baking sheet and back them in a 375® oven for 30-40 minutes, flipping them over around 15 to 20 minutes into the baking. While the wings are baking, I mix three different hot sauces (regular, chipotle and green jalapeno) with a tablespoon of butter and cook on the stove until well combined. I never measure how much of each I put into the sauce, but Ive ordered them based on which one has the most to which has the least amount added to make the sauce delicious. If i had to guesstimate a ratio, I would say 80% regular, 15% chipotle and 5% green jalapeno. Once the wings have cooked through, I basted them in the sauce at least 2-3 times and baked for an additional 5 minutes between each basting. Each time you make them, these wings taste different every time I make ...
When youre a wing lover, some wings stay in your memory for a while as being exceptional. A few years ago I went to the Sunset Grill & Tap and I still remembered those wings. They had a particularly sweet taste that was reminiscent of fresh peppers and other flavors. So I was anxious to try them again while in Boston last Saturday for a little day trip to the New England Aquarium. The Sunset is best known for its formidable beer selection - 112 on tap and 100s more in bottles. A beer lovers dream come true. But the food is pretty impressive too. Especially the wings…. These are great wings. A little nontraditional in their recipe, but hot, saucy, spicy, and perfectly cooked. The wings are average size and cooked to an ideal doneness and crispiness. Theres also a good serving of them as well. However, its the sauce that makes the difference here. The sauce is thick and flavorful. Theres a lot more going on in here than margarine and Red Hot. Theres flecks of peppers visible in the sauce ...
Lepidopteran insects present a complex organization of appendages which develop by various mechanisms. In the mulberry silkworm, Bombyx mori a pair of meso- and meta-thoracic discs located on either side in the larvae gives rise to the corresponding fore- and hind-wings of the adult. These discs do not experience massive cell rearrangements during metamorphosis and display the adult wing vein pattern. We have analysed wing development in B. mori by two approaches, viz., expression of patterning genes in larval wing discs, and regulatory capacities of larval discs following explantation or perturbation. Expression of Nubbin is seen all over the presumptive wing blade domains unlike in Drosophila, where it is confined to the hinge and the wing pouch. Excision of meso- and meta-thoracic discs during the larval stages resulted in emergence of adult moths lacking the corresponding wings without any loss of thoracic tissues suggesting independent origin of wing and thoracic primordia. The expression ...

The results of the research were startling. Other free-flying creatures, including other types of insects, lack the unique type of mechanism observed, so the wing design of the butterfly was totally unexpected. During an upward stroke, the optimized design of the flexible wings produces a specialized cavity that creates an air-filled pocket. As the wings continue to compress, the air is forced out like a jet engine, propelling the butterfly forward. The downward wing stroke has yet another purpose: stabilizing the flight pattern and keeping the butterfly in the air. Not only does this mechanism allow for efficient flight, but it also allows for rapid takeoff when the butterfly needs to escape a predator ...

Mature male Calopteryx japonica damselflies have dark-blue wings, due to darkly coloured wing membranes and blue reflecting veins. The membranes contain a high melanin concentration and the veins have a multilayer of melanin and chitin. Female and immature C. japonica damselflies have brown wings. We have determined the refractive index of melanin by comparing the differently pigmented wing membranes and applying Jamin-Lebedeff interference microscopy. Together with the previously measured refractive index of chitin the blue, structural colour of the male wing veins could be quantitatively explained by an optical multilayer model. The obtained melanin refractive index data will be useful in optical studies on melanized tissues, especially where melanin is concentrated in layers, thus causing iridescence.

National Chicken Wing Day is fast approaching and on July 29th and there is no better place to celebrate than at Anchor Bar, the birthplace of the Original Buffalo Wing (Pictured: Teriyaki Sesame Wings). Since 1964, Anchor Bar has been serving up their signature Buffalo wings that Teressa Bellisimo created on a whim. After her son Domenic and friends stopped by looking for a late night snack, Teressa took chicken wings, usually meant for the stock pot, fried them up, and coated them with a now famous special sauce to create the one and only Buffalo Wing.. As a result of that night, in 1977 Buffalo Mayor, Stan Makowski, proclaimed July 29th as National Chicken Wing Day. ...
Research Focus: Because of a large gap in the fossil record, a debate on the origin of insect wings has roared on for more than 200 years between two competing hypotheses: tergal or pleural origin. Recent molecular evidence has provided support for a dual-origin of insect wings. I aim to investigate the contribution of two distinct wing serial homologs to ectopic wing formation in the red flour beetle Tribolium castaneum, to further inform the dual-origin hypothesis of insect wings. Tribolium castaneum is an emerging model system which has been shown to bare two distinct wing serial homologs on the wingless first thoracic segment (T1), one tergal and one pleural, maintained in the ancestral state by the Hox gene Sex combs reduced (Scr). Partial disruption of Scr function reveals that both of these distinct wing serial homologs contribute to the formation of the ectopic wing that subsequently develops on T1. I utilized FAIRE-seq to chemically isolate and sequence potential enhancers for the wing ...

Furin is an evolutionarily conserved proprotein convertase (PC) family enzyme with a broad range of substrates that are essential for developmental, homeostatic, and disease pathways. Classical genetic approaches and in vitro biochemical or cell biological assays identified that precursor forms of most growth factor family proteins are processed by Furin. To quantitatively assess the potential role of Furin in cleaving and modulating intercellular dispersion of a Drosophila signaling protein, we developed a simple assay by combining genetics, ex vivo organ culture, pharmacological treatment, and imaging analyses. The protocol herein describes how to ex vivo culture Drosophila wing imaginal discs expressing a fluorescently tagged Drosophila Fibroblast Growth Factor (FGF, Branchless/Bnl) over a long period of time in the presence of Furin inhibitors and monitor the cleavage and intercellular dispersion of the truncated Bnl parts using microscopy. Although the assay described here is for assessing the
Monarch butterflies who have dark orange wings fly further than those with light orange wings, a new study has revealed.. Previous work has shown that monarch colouring is intended to warn their predators about their bitter taste and toxicity, and that migratory butterflies are darker coloured than non-migratory ones, suggesting an association between darker colour and increased fitness.. The current work, led by Andrew Davis of the University of Georgia, provides further evidence for this association.. The researchers tested 121 captive monarchs in an apparatus called a tethered flight mill, where they can quantify butterfly flight speed, duration, and distance, and found that those with darker orange wings overall flew longer distances than those with lighter wings.. Butterfly researchers dont often look closely at colour variation between individuals of the same species. The results of this project will pave the way for a new line of inquiry into the significance of butterfly wing colour, ...
The evolution of the haltere has provided flies with the capacity to monitor inertial forces separate from the aerodynamic forces produced by the wings. However, only two insect orders, Diptera and Strepsiptera, possess such structures [14]. The vast majority of insects instead possess the antecedent structures of halteres: an additional pair of wings. Thus, how most flying insects collect information about their body dynamics through mechanosensory structures is a long-standing problem in insect flight control. Although recent evidence suggests that the antennae of the hawkmoth Manduca sexta detect Coriolis forces and aid the animal in maintaining flight stability [15-18], the use of antennae as putative inertial sensors does not preclude other structures from serving a similar role.. Since halteres are evolutionarily derived from wings, the wings of all insects might be capable of providing information about body rotations. Indeed, recent electrophysiological and behavioural evidence suggests ...
Mimicry where warning signals in different species evolve to look similar has long served as a paradigm of convergent evolution. However, little is known about the genes that underlie the evolution of mimetic phenotypes nor to what extent the same or different genes drive such convergent evolution. Here, we characterize one of the major genes that controls mimetic wing pattern evolution in Heliconius butterflies. Mapping, gene expression, and population genetic work all identify a single gene, optix, that controls radically variable red wing patterns across multiple species of Heliconius. Our results show that the cis-regulatory evolution of a single transcription factor can repeatedly drive the convergent evolution of complex color patterns in distantly related species, thus blurring the distinction between convergence and homology.. ...
Most insects use a method that creates a spiralling leading edge vortex. These flapping wings move through two basic half-strokes. The downstroke starts up and back and is plunged downward and forward. Then the wing is quickly flipped over (supination) so that the leading edge is pointed backward. The upstroke then pushes the wing upward and backward. Then the wing is flipped again (pronation) and another downstroke can occur. The frequency range in insects with synchronous flight muscles typically is 5 to 200 hertz (Hz). In those with asynchronous flight muscles, wing beat frequency may exceed 1000 Hz. When the insect is hovering, the two strokes take the same amount of time. A slower downstroke, however, provides thrust.[6][7] Identification of major forces is critical to understanding insect flight. The first attempts to understand flapping wings assumed a quasi-steady state. This means that the air flow over the wing at any given time was assumed to be the same as how the flow would be over ...

Seasonal polyphenism demonstrates an organisms ability to respond to predictable environmental variation with alternative phenotypes, each presumably better suited to its respective environment. However, the molecular mechanisms linking environmental variation to alternative phenotypes via shifts in development remain relatively unknown. Here we investigate temporal gene expression variation in the seasonally polyphenic butterfly Bicyclus anynana. This species shows drastic changes in eyespot size depending on the temperature experienced during larval development. The wet season form (larvae reared over 24 degrees C) has large ventral wing eyespots while the dry season form (larvae reared under 19 degrees C) has much smaller eyespots. We compared the expression of three proteins, Notch, Engrailed, and Distal-less, in the future eyespot centers of the two forms to determine if eyespot size variation is associated with heterochronic shifts in the onset of their expression. For two of these ...

In our study, we investigated if and how proprioceptive feedback influences the rhythm of the myogenic wing beat oscillator. We concentrated on mechanosensory input from the halteres - specialized „gyroscopic sensory organs of flies. The halteres are known to activate the motor neurons of miniscule steering muscles, which in turn modulate the motion of the wings. In our experiments [2], tethered flying fruit flies (Drosophila melanogaster) were vibrated by a piezoelectric actuator to stimulate the haltere mechanosensory pathways. We used a laser Doppler interferometer to measure the vibrations of the tether resulting from the superposition of the piezo-delivered stimulus and the flys wing beat. We determined the phase relationship between the wing motion and the mechanical stimulus in each wing stroke and applied an automated synchrogram analysis [3] to detect entrainment and higher-order synchronization. The flies synchronized with the stimulus for specific ranges of stimulus amplitude and ...
The butterfly wing can seemingly thank two specific genes for the intricate and colorful patterns that adorn it and help it mate and survive.
The rich, shimmering colors of some butterfly wings are produced not by pigments, but by a special geometric formation of cells, a new study suggests.
Abstract The infrared (ATR-FTIR) and Raman spectroscopy was used for the structural characterization of honeybee wings. Protein, chitin, and lipid characteristic spectral features were detected using both methods. The protein secondary structure was predominantly composed of the β-sheet molecular conformation with β-turns or coil contributions. The vibration modes of the side-chain aromatic amino acid residues (tyrosine, phenylalanine, tryptophan) occurred in the wing spectra. The results of discriminant analysis showed that the infrared spectroscopy of the wing in combination with a multivariate analysis seemed promising for a resolution of the chemical structure of the wings based on lipid, proteins, and chitin content.

Coco Cream and Smoked Fish Wing Bean Stew-The wing bean is a climbing herbaceous legume and although all parts of the plant are edible, it is grown mostly for its green pods and beans. Wing bean seeds (or WBS) have a nutritional value similar to that of soybeans containing about 30-32% of protein and 16% of oil. They are also high in phosphorus, calcium, magnesium, iron and B-vitamins. It was also found WBS have hypotensive properties and may contribute to the cardio-vascular health due to high content of monounsaturated oleic acid. Wing beans are relatively hard to cook and just like soybeans they should be heat treated to eliminate any anti-nutritional factors like the trypsin inhibitor which hampers digestion. By presoaking the beans in a soda & salt solution this may reduce the cooking time.

Butterfly wings may rank among the most delicate structures in nature, but they have given researchers powerful inspiration for new technology that doubles production of hydrogen gas - a green fuel of the future - from water and sunlight.. The researchers presented their findings in San Diego on March 26 at the American Chemical Societys (ACS) 243rd National Meeting & Exposition.. Tongxiang Fan, Ph.D., who reported on the use of two swallowtail butterflies - Troides aeacus (Heng-chun birdwing butterfly) and Papilio helenus Linnaeus (Red Helen) - as models, explained that finding renewable sources of energy is one of the great global challenges of the 21st century. One promising technology involves producing clean-burning hydrogen fuel from sunlight and water. It can be done in devices that use sunlight to kick up the activity of catalysts that split water into its components, hydrogen and oxygen. Better solar collectors are the key to making the technology practical, and Fans team turned to ...
Abstract: Dragonfly wings, which consist of the veins and membranes, are highly specialized flight organs adapted to cope with the individual flight behavior of each dragonfly. Therefore, it is important and necessary from a bionic view that the investigation on microstructure of elements how to affect their mechanical behaviors. In this study, we focus on effects of microstructure on mechanical characteristics of dragonfly wing vein. These results indicate that the microstructure of vein is a complex sandwich structure due to being obviously superior to one typical material, which consists of chitin shell and protein meat with some fibrils. This sandwich structure can be subjected to the rather greater bending loading and torsional deformation based on the von Mises stress and flexural deformation analysis of finite element method (FEM). They assist us to understand and design the new high strength-to-weight ratio of composite materials or structure. Accepted by Composites Science and ...
Irregularity of the size and distribution of nanostructures on the surface of the butterfly wing causes low reflection of light at all view angles. (Photo: Radwanul Hasan Siddique, KIT). For research into this so far unstudied phenomenon, the scientists examined glasswings by scanning electron microscopy. Earlier studies revealed that regular pillar-like nanostructures are responsible for the low reflections of other animals. The scientists now also found nanopillars on the butterfly wings. In contrast to previous findings, however, they are arranged irregularly and feature a random height. Typical height of the pillars varies between 400 and 600 nanometers, the distance of the pillars ranges between 100 and 140 nanometers. This corresponds to about one thousandth of a human hair.. In simulations, the researchers mathematically modeled this irregularity of the nanopillars in height and arrangement. They found that the calculated reflected amount of light exactly corresponds to the observed ...
