Bibio cf.
johannis male.
I don't know all the European species. In America we have dozens of species in total but only about five common and widespread spring species.

Thank you John and thank you Theo - so it's not possible to delete the "cf."?

Thank you Sundew. - As
Colobo wrote: "... the pear-shaped first tarsomere of hind leg, (...) is characteristic for this species. The black tip of hind tibia, and black tips of first and second tarsomeres of hind legs are also generally present in femoralis.", my specimen could be B. femoralis although there is no black tip of hind tibia (see also my enlargement photograph).
Otherwise my fly looks for me very similarly to the B. joannis in the gallery of Diptera (also with pear-shaped first tarsomere of hind legs).
Solution?

These little ones are tricky. I checked my photo collection, and here is a combination of males that I consider
B. femoralis and
B. johannis, but with a "cf." to be on the safe side. Without a collected specimen sent to an expert we shall never be absolutely sure in these cases, and females are still much more difficult. However, the colour of the hind leg of your male fits
B. johannis better, and the "pear" is a bit long, too, so "cf.
johannis" would indeed be the best choice.
I can live with the many "cf.s" in my photo collection! Sure, a substantiated name would be more satisfying, but compared to the knowledge of an average citizien ["Iiiieh - a biting insect - kill it!"] we are much closer to the genuine truth :D.
Best wishes, Sundew
