Congo Floor Maggot Fly

A yellowish-brown blow fly whose larvae are unique among Diptera in being temporary ectoparasites that feed on sleeping humans. Larvae live in the dirt floors of huts and emerge at night to feed on the blood of sleeping people, then retreat into the floor. Adults do not bite.
