Stem boring species of weevil weevils. Medical search. Frequent questions

However, a group of scientists recently shed light on a lesser-known but highly diverse group of pollinators that often remain hidden in plain sight - weevils, specifically, long-snouted beetles. (earth.com)
Beetles, with about 400,000 species recognized by scientists, represent the largest group of animals in the world. (earth.com)

a) The larva of any one of numerous species of boring beetles, esp. (freedictionary.org)
Wood fretter (Zo['o]l.), any one of numerous species of beetles whose larv[ae] bore in the wood, or beneath the bark, of trees. (wordaz.com)
Adult beetles cause damage by feeding on fruits, flower buds and leaves depending on the species. (koppert.com)
Buprestidae is a family of beetles known as jewel beetles or metallic wood-boring beetles because of their glossy iridescent colors. (wikipedia.org)
