Ciao

Lars!

thanks for your nice pictures. Your specimen is a female belongin to the genus Hedychrum.
It can be the female of Hedychrum nobile or H. niemelai, but I cannot tell you which one based on the picture.

Cheers
Paolo

I think it is a Hedychrum species, but not nobile/niemelai or rutilans. Female?
Location: southern part of Holland, nature reserve on Achillea, rather large and robust behind.

Dear Rolf :welcome: You're right and your specimen belongs to the genus Hedychrum Latreille. It can be the female of Hedychrum nobile (Scopoli) or Hedychrum niemelai Linsenmaier. They are both known from Denmark. Unfortunately, I cannot ID for sure ...

... specimens by photos. The only way is that you collect more female specimens and examine the shape of the last sternite. Often H. nobile and H. niemelai fly together in the same site. Therefore you should collect more specimens. In my experience, the larger specimens are always only H. nobile ...

Hello,

Yesterday I found some chrysidids within a Cerceris arenaria colony. After some research I think it should be Hedychrum nobile or H. niemelai. However, I can't find what the differences are to distinguish both species. So it would be great if someone could help me with that.

Jeroen!

You're absolutely right. It is not possible to ID this male specimen from the picture.

My personal feeling (based on the robust habitus) is that could be H. nobile, but this ID is not confirmed.

Cheers
Paolo

I fear that there is no way to be sure of which one this was. But you're the experts.
Anyone?

It was photographed in the Netherlands (Nijmegen) on June 20.

Thanks!
Jeroen
