Horse fly are member of insects on the family Tabanidae (order Diptera), but more specifically any member of the genus Tabanus. These stout flies, as small as a housefly or as large as a bumblebee, are sometimes known as greenheaded monsters; their metallic or iridescent eyes meet dorsally in the male and are separate in the female. Gad fly, a nickname, may refer either to the fly’s roving habits or to its mouthparts, which resemble a wedge-shaped miner’s tool.
