Hello,
I observed this Bibio the 30th of April in the north of France, approximately 8 mm. I think of a male of
Bibio anglicus but hesitate a lot with
Bibio marci,
I don't know how to differentiate them with certainty ?
Cordially Maxime

The wing venation excludes B. marci, however, the spur on front tibia suggests leucopterus. Did you consider this species ?

No I didn't know this species. Do you have documents illustrating these
Bibio like the wing venation… for me to learn ?

Please check Sundews recent post for a link to Verbeke (1971). Another option is Frreman & Lane in Handbook British Insects, or my own masterpiece (ahum) from 1997, in dutch.

Thank you very much for your documents, so for this Bibio, we can conclude in
Bibio leucopterus ?

To me, it remains unclear. The wing seems too dark for leucopterus and the front spurs seem ok in one pic, but not ok in the other.

ICertainly not
leucopterus, which has wings clearly whitish in male. I would rather incline for
anglicus (but with a question mark...)
