Subject: Looks like a Rose Sawfly BUT…….
Geographic location of the bug: Five Ashes, East Sussex, UK
Time: 03:21 AM EDT
I, at first, thought this must be an Ichneumon wasp because of what appears to be very long antennae and ovipositor, but the coloration exactly matches a Rose Sawfly. Any help gratefully received.

This is definitely a parasitoid, not a Sawfly. We suspect it is a Braconid, a family closely related to the Ichneumons. Here is an Alchetron page with some similar looking Braconids, and Alamy has a nice image. We are reluctant to speculate on a species, but if you find out any additional information, please give us an update.
Many thanks Daniel. You are totally on the right track. I now think it’s likely to be Atanycolus sp.
Best wishes, Nigel.
