Pristiphora abietina (Christ, 1791)

Pristiphora abietina - Pristiphora abietina group

In the female the basal part of the sawsheath is parallel sided when viewed from above and the sides of the 9th tergite alongside the sawsheath are dulled by microsculpture between the punctures. This species is smaller than the similar Pristiphora compressa. The ovipositor is longer than the four basal tarsal segments and longer than the middle tibia.

Pristiphora abietina larvae feed on norway, sitka and other spruces and have been locally destructive in the past.
