Hi, yesterday I've found my first Bibio leucopterus in the garden on a daisy.
Determined by the Verbeke-key (hopefully correct):

8-9 mm, wing-membrane heavily smoky - appear brownish to blackish;
Veins also strongly pigmented...
crossvein r-m slightly longer than basal radial vein R2-5.

Yes, it is a paradox, female leucopterus has actually black wings ...
