Face fly

Face fly (Musca autumnalis), insect that feeds on the body fluids of livestock. It is speculated that the first face flies, discovered in Nova Scotia in 1952, came from Europe. The face fly can transmit diseases to horses, donkeys, and cattle. Resembling the common house fly, the face fly is different in that the larvae (maggots) develop faster than house fly maggots and are yellowish instead of white.
