A small dark deer fly with mostly blackened wings and green iridescent eyes. It is an aggressive daytime biter commonly encountered near wooded wetlands.
Did You Know?
It is most active during overcast humid days and tends to bite repeatedly if swatted away without being killed.

A major vector of African trypanosomiasis (sleeping sickness). Unique among flies for giving live birth to a single large larva nourished internally with a milk-like substance.
