Urocerus augur (Klug, 1803)

Urocerus augur

Very similar to the common Urocerus gigas, but the yellow behind the eyes is more extensive and the hind tibia black in at least the apical half. In the female the ovipositor is longer being about as long as the forewing.

Urocerus augur larvae feed in the timber of coniferous trees and take 2 to 3 years to mature.
