Bibio (fly)

Bibio (fly)
Bibio, March flies or St. Mark's flies, is a genus of flies (Diptera).
Biology
Bibio larvae live in grassy areas and are herbivores and scavengers feeding on dead vegetation or living plant roots. Some species are found in compost.
In some areas, Bibio flies are regular flower visitors and they are suggested to be pollinators of several plant species, such as hogweed (Heracleum sphondylium) and mouse-ear hawkweed (Hieracium pilosella).
Bibio flies also show strong sexual dichotomy, with males and females having significant differences in body morphology.
