I saw these two specimen of Bibio sp. on the light-tower near my house in south-west of Germany on 09th may in the night.
The size of the male was about 7 mm, the female about 10 mm.
May ID possible?
Thanks and best regards

Hi Ulrich, I'm quite sure, that the female is B. varipes (the abdomen must be yellow ventrally). Unfortunately I cannot see the colour of the hair on top of the male's thorax - if it's black, it may be the male reticulatus. Bibio are tricky and it's easier if we see dorsal and lateral views.

Greetings, Eric

Thank you, Eric! Looking at all my pictures of the male one I think the hairs on the top of the thorax actually are black.
