Looks a lot like C. impressa, but it's hard to say with the ignita-complex, often you have to be familiar with specimens from the area to be confident

it's a female in the ignita-group for sure, looks like on of the species with slender ovipositor. Perhaps impressa/longula/ignita s.s., hard to say for sure from just images I'm afraid

yes, that looks correct to me, but these are hard to ID definitively from just images

Belgium, 9th august 2022.
Keyed as C. impressa with "An illustrated key to the cuckoo wasps of the Nordic and Baltic countries".

New to determinating cuckoo wasps, so might be totally wrong here. So is my determination correct? I can post extra pictures on request.

Hallo Horst,

based on the colouration, I would say that your specimen is a female of
Chrysis impressa,

Cheers

Not really possible to say with these ignita-group specimens, it does not look like the true ignita to me, rather more like impressa/angustula/corusca etc

I cannot easily place this specimen, the punctures on the abdomen seems far too fine and dense for C. impressa , as does the quite narrow apical rim. The coastal location, punctuation, red sternites and white hairs makes me think of C. rutiliventris , but it seems less "particular" ...

I'm not sure about this one.

In some aspects it looks like Chrysis impressa, but I never found it alive and I don't know it's real colour in nature (I checked only a few pictures)

Maybe Alex or another friend from Central or North Europe can confirm or not.

Cheers

the abdomen strikes me more as C. impressa or C. schencki and the species close to them

Hi,

I'm not sure, I feel more confortable with C. impressa for the punctuation on T2 not so coarse, olive (?) colour on mesoscutum, first tarsomere of metatibia longer, yet the lateral margin of T3 is slighlty arcuate.

Do you have a picture of the black spots on the second sternite?
