Hi Joerg, B. johannis, I think.

Hi Eric,

that was also my first thought but I can't see any black stigma so I was confused.

Hi Joerg, yes, the wings seem to be brownish and stigma is hard to see (depending on the angle?) and it's a little late for johannis, but the hairs seem to be completely black and metatarsus III distinctly thickend - that should exclude varipes.

The tibiae look awfully black to me for johannis and 25 may is very late for johannis. I would consider reticulatus.
