Hello,
This one is very small (Approx 4-5 mm). Looks like a Gymnosoma, but is it possible to find out which one ?

Thanks for your help

It's hard to gauge scale ... and the distinction between Cistogaster and Gymnosoma is the length of the antennae (which we can't see in this photo). But I'd guess that it is most likely to be Cistogaster globosa (male) but it might be Gymnosoma nitens as an outside bet :)

Do you have any photos showing the antennae?

Hello Chris
Thanks, I believe you're right and it's Cistogaster. My only picture showing the antennae is lousy (to say the least) but it seems to show they are indeed rather short

Yes, I agree - those antennae are short ... the abdominal markings also match male Cistogaster globosa better :)
