Oestrus ovis
Gadfly Gad"fly` (g[a^]d"fl[imac]`), n.; pl. {Gadflies}. [Gad + fly.] (Zo["o]l.) Any dipterous insect of the genus {Oestrus}, and allied genera of botflies. [1913 Webster]

Note: The sheep gadfly ({Oestrus ovis}) deposits its young in the nostrils of sheep, and the larv[ae] develop in the frontal sinuses. The common species which infests cattle ({Hypoderma bovis}) deposits its eggs upon or in the skin where the larv[ae] or bots live and produce sores called wormels. The gadflies of the horse produce the intestinal parasites called bots. See {Botfly}, and {Bots}. The true horseflies are often erroneously called gadflies, and the true gadflies are sometimes incorrectly called {breeze flies}. [1913 Webster]

{Gadfly petrel} (Zo["o]l.), one of several small petrels of the genus {Oestrelata}. [1913 Webster]
