Moved from Orthopelmatinae.

Moved from Ichneumon Wasps.


Wing venation seems to suggest this could be a male of Tersilochinae. Barycnemis harpura (Schrank) is an associate of Diplolepis rosae and occurs in North America as well as Europe.

Thanks, Bob.
That's great to know. Wondered if it might be an ichneumon.

Probable ID
Dr. Klaus Horstmann informs me that the association of Barycnemis harpura with Diplolepis rosae is 200 years old and has not been substantiated. He suggests that the specimen is more likely to be a species of Orthopelma, as those are known parasitoids of Diplolepis. The species Orthopelma mediator (Thunberg) has been commonly reared from D. rosae in Europe and this page has photos and a discussion of the biology. The species has been recorded from British Columbia. Additional photo of the male of Orthopelma mediator.
