Male Horntail

Dear Roger,
This is a male Horntail in the genus
Urocerus, which we identified thanks to this BugGuide image, and there is a comment attributed to Dave Smith on that posting that states:  “Urocerus sp., male. Could be either U. albicornis or U. flavicornis. The males are difficult to separate.”  Horntails are sometimes called Wood Wasps, but they do not sting, and no male wasps are capable of stinging anyways.  Here is an image from our archives of the female Urocerus albicornis and here is an image of the female Urocerus flavicornis.  The ovipositor of the female is used to lay eggs beneath the bark of conifer trees and its appearance is responsible for the common name Horntail.
