A black fly or blackfly [1] (sometimes called a buffalo gnat, turkey gnat, or white socks) is any member of the family Simuliidae of the Culicomorpha infraorder. It is related to the Ceratopogonidae, Chironomidae, and Thaumaleidae. Over 2,200 species of black flies have been formally named, of which 15 are extinct. [2]
The flies are pool feeders. Their saliva, which contains anticoagulants, a number of enzymes and histamine, is mixed with the blood, preventing clotting until it is ingested by the fly. These bites cause localized tissue damage, and if the number of feeding flies is sufficient, their feeding may produce a blood-loss anaemia.
The Blandford fly (Simulium posticatum) is a species of black fly. It is a biting insect found in Europe, Turkey and western Siberia. It spends its larval stage in the weedbeds of slow flowing rivers and when the fly emerges, the female seeks a blood meal before mating. It usually bites the lower legs causing pain, itching and swelling.
Usually, many bites are required before infection occurs. [7] These flies live near rivers, hence the common name of the disease. [6] Once inside a person, the worms create larvae that make their way out to the skin, where they can infect the next black fly that bites the person. [1]
