Thanks Alex!

C. indigotea always have four abdominal teeth, while this specimen obviously have three, so I guess thats a confirmation

Thanks for your reply Alex! The only other possibility for the Netherlands seems C. indigotea. And I don't think that is the case. So thanks for your confirmation.

The tridentate apical tergum is unique to the genus Trichrysis, atleast in northern/middle europe, which removes C. iris, Spinolia ... other blue-green chrysidids. The most common species is the ubiquitous T. cyanea, but there are more species in the genus outside northern europe, I'm not ...

Thank you for any hints.

Regards
