This Bibio came to light at the Island of Gotland, in the Baltic Sea, Sweden. It was the 23 of September 2022.
Could it be Bibio Longipes.

I am very thankfull for help.

Thanks in advance
Stefan Risberg

Hi Stefan, I think it's B. clavipes:
The pterostigma seems to be limited by the subcosta and the wings are not hyaline but more milkwhite.

IDing from picture can be very tricky. Especially, since the degree-of -milkyness on the wing depends on angle of view and hence can be very obvious in the field and very deceiving in one still.

I couldn’t / wouldn’t make the call here.

Thank you Eric and Theo for your reply.
I have a Photo from another angle and the wings look milky to me. So likely Clavipes.
