Some species have long legs as well. The common locust borer and several related species are chestnut brown with bright yellow stripes and mimic a wasp. The larvae are white, segmented worms, with slightly enlarged, round heads. They lack visible legs. Larvae bore under the bark of trees into the wood.
Some species are very destructive.
Adult clear-wings mimic wasps in color and hovering behavior. The larvae are white, legless worms that resemble round-headed wood borers. Clear-wing borers, however, do not have enlarged, rounded heads. The larvae bore into roots, stalks, branches and trunks of many species of trees and shrubs. Visuals associated with this text.
