Horn Fly

Scientific name: Haematobia irritans (Linnaeus)
(Diptera: Muscidae)

Facts: The horn fly looks like the house fly but is only about half as large. Adults have piercing-sucking mouthparts and suck blood. Adults rest with their heads pointed downward on the backs of livestock. Larvae have hooks in their mouthparts and feed in cattle manure.
