Horse flies and deer flies [a] are true flies in the family Tabanidae in the insect order Diptera. The adults are often large and agile in flight. Only female horseflies bite land vertebrates, including humans, to obtain blood. They prefer to fly in sunlight, avoiding dark and shady areas, and are inactive at night.
The life of the parasite can be traced through the black fly and the human hosts in the following steps: [13] [14] A Simulium female black fly takes a blood meal on an infected human host and ingests microfilaria. The microfilaria enter the black fly's gut and thoracic flight muscles, progressing into the first larval stage (J1.).
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]
Tabanidae—horse and deer flies The Brachyceran infraorder Tabanomorpha is a small group that consists primarily of two large families, the Tabanidae (horse and deer flies) and Rhagionidae (snipe flies), and an assortment of very small affiliated families, most of which have been (or could be, or sometimes are) included within the Rhagionidae.
Before heading outdoors in Fort Worth, here’s what to know about this biting pest.
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.
Black flies often don't respond to bug spray, so plan accordingly and wear lightweight, long-sleeved clothing if you venture out to this area. Related: 14 Budget-Friendly Places for Whale Watching ...
