Hello,

I observed this Bibio on the 13th of April in the north of France. I hesitate between Bibio anglicus and marci, I think of Bibio anglicus, do you have criteria to easily differentiate them ?

Cordially Maxime

Anglicus is half the size of marci and the wing venations differs.
I don’t expect the first anglicus before april 20th.
This looks like marci.
