A black fly (sometimes called a buffalo gnat, turkey gnat, or white socks) is any member of the family Simuliidae of the Culicomorpha infraorder. They are related to the Ceratopogonidae, Chironomidae, and Thaumaleidae. Over 1,800 species of black flies are known (of which 11 are extinct). Most species belong to the immense genus Simulium. Most black flies gain nourishment by feeding on the blood of mammals, including humans, although the males feed mainly on nectar. They are usually small, black or gray, with short legs, and antennae. They are a common nuisance for humans, and many US states have programs to suppress the black fly population. They spread several diseases, including river blindness in Africa (Simulium damnosum and S. neavei) and the Americas (S. callidum and S. metallicum in Central America, S. ochraceum in Central and South America).

Famous quotes containing the words black and/or fly:
“Richard. Give me a calendar.
Who saw the sun today?
Ratcliffe. Not I, my lord.
Richard. Then he disdains to shine, for by the book
He should have braved the east an hour ago.
A black day will it be to somebody.”
—William Shakespeare (1564–1616)
“The son will run away from the family not at eighteen but at twelve, emancipated by his gluttonous precocity; he will fly not to seek heroic adventures, not to deliver a beautiful prisoner from a tower, not to immortalize a garret with sublime thoughts, but to found a business, to enrich himself and to compete with his infamous papa.”
—Charles Baudelaire (1821–67)
