Welcome Markus!

Sorry for the delay, I just saw your post.

Yes, you're fully right,

It is more difficult to identify a specimen based on its size if it is about 6 mm, because you can always find small specimens of [i] H. nobile. [/ i]

thanks Paolo!

I'll see if I can make a post with more pictures.

cheers,
Nick

The question on hairs is only for sex ID, if they are erected, then they are males (nobile, niemelai, gerstaeckeri ), if they are lying down the specimen is a female. If the female is green, in central Europe we have only gerstaeckeri ...
