Horntail: Urocerus albicornis

Hi Rae Ann,
We are positively thrilled to be able to post your magnificent image of a very impressive Horntail,
Urocerus albicornis, a species with a range limited to the Pacific Northwest.  Horntails are classified in the order Hymenoptera which includes Ants, Bees and Wasps, but Horntails, which are frequently called Woodwasps, cannot sting.  The female uses her impressive ovipositor to lay eggs beneath the surface of trees or stumps, and the wood boring larvae feed on the wood.  According to BugGuide:  “hosts include fir, larch, spruce, pine, Douglas-fir, hemlock, and western red cedar.”  Of the family, BugGuide notes:  “Some are serious pests of trees and spread as larvae with lumber trade.”
