(Bibio femoralis)
Bibio femoralis is a species of fly. It was first described by Johann Wilhelm Meigen in 1838. Bibio femoralis belongs to the genus Bibio, and family Bibionidae. Bibio, March flies or St. Mark's flies, is a genus of flies (Diptera). 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).
