Horntail

Dear Lamont,
This is a Giant Wood Wasp or Horntail in the genus Urocerus, and based on images and sighting information on BugGuide, we believe it is Urocerus flavicornis.  The ovipositor at the end of the abdomen indicates that this is a female.  The female uses her ovipositor to deposit her eggs beneath the bark of trees and the larvae that hatch bore in the wood.
