Looks a lot like the common species Chrysis impressa, the only that isnt a good fit I can find is the apical teeth on tetgite 3, but then these wasps vary quite a bit

Paolo, thanks for the information. I have Ancistrocerus in my garden but I don't know which species. They are not ease/impossible to id from pics.

Yes, recently Parn et al. (2015) suggested Ancistrocerus claripennis , Ancistrocerus parietinus and Ancistrocerus trifasciatus as possible hosts. You can find some additional distributional data in Paukkunen et al. 2014, whereas an illustrated key of the North European species is next to come. You c...

Dear Jonas

thanks for these interesting pictures.
