Taken 5.v.2008, southern England on last year's Diplolepis rosae gall, about 3mm long. Is this Pteromalus bedeguaris or is it one of the other pteromalids associated with D.rosae?
Excellent - thanks We have a lot of Diplolepis rosae galls on my local nature reserve and I am really interested in the associated parasitoid/inquiline communities
