Genus Bibio Geoffroy, 1762

The genus is usually easily recognized by the wing venation, the shape of the anterior tibiae as well as the general habitus. Surprisingly, we still found that a number of described species belonging to this genus had been placed in other genera, and some species placed in Bibio belonged to other genera. Bibio species are present from most localities except Chadrat and Barbeiras. In some (e.g., Aix-en-Provence and Monteils) they predominate while in others (e.g. Céreste and Bois d’Asson) they are relatively infrequent.
