Pristiphora glauca - Glaucous Larch Sawfly
Pristiphora erichsonii

This species is so similar to Pristiphora wesmaeli that adults cannot often be distinguished. Even the genitalia are hard to distinguish. The earlier emergence of adults and earlier larval feeding period is thought to be a more reliable method of distinguishing between the two species.

Pristiphora glauca larvae feed on European larch and Japanese and Dahurian larch where introduced.
