It does look like a dragonfly in it's Nymph stage. If it is, when it emerges from the water it will attatch it's self to a stable leaf/twig/stem etc and metamorphose just as a butterfly to change into it's adult form

its a parasitic wasp belonging to this superfamily. I'll post some more once I have checked it out. Cheers!

Re: Philotrypesis

Thanks for your help! It was actually caught in a malaise trap in Berkshire. Does this effect your Philotrypesis ID?

It's kind of puzzling, since Philotrypesis live in figs, as parasitoids of agaonid fig wasps, neither of which occur naturally in the UK. Do you know of anyone with a fig tree locally or importing fig fruits?

Silwood Park

There are a number of biologists at Silwood Park field station who study parasitic wasps, possibly it escaped from their labs?

I don't know of any fig trees

I don't know of any fig trees on Silwood campus, so I guess that is a possibility! I'll find out if it could be a rogue wasp or if there is a fig tree nearby and let you know.

Thanks again
