What is this cute one? Its in fact something the cat dragged in at 8th of august last year... I think it was about 30mm. Southern norway, near mixed forest and river...

Siricidae. Urocerus gigas or a related species.

Thanks, but doesnt it have too many yellow stripes to be gigas? I have only looked online for pictures... Or is it because males and females are quite different in apperance? And if so, then this is a male? From googling it seems that could be the case...

Hi Trond,

I have to admit I know very little about Siricidae. I found on www.faunaeur.org that Sirex juvencus and Tremex fuscicornis are known from Norway. Your specimen might be a male of the latter. Maybe one of the others knows more about Siricidae!?

This link takes you to an illustrated guide (and key I think). The file is nearly 6Mb in size.......

Its a male of Urocerus (gigas), and not of Tremex. I am not the last specialist for this group, but key and photos in the web agree well. The males are marked different from the females, and in the web you always will find females. On www.galerie.hymis.de, you will find fotos of the most important species of Siricidae in Central Europe.

Regards Christian

May we use your foto for your gallery? The male still lacks.
