Bot"fly`, n. (Zoöl.)
Definition: A dipterous insect of the family (Estridæ, of many different
species, some of which are particularly troublesome to domestic
animals, as the horse, ox, and sheep, on which they deposit their
eggs. A common species is one of the botflies of the horse
(Gastrophilus equi), the larvæ of which (bots) are taken into the
stomach of the animal, where they live several months and pass
through their larval states. In tropical America one species
sometimes lives under the human skin, and another in the stomach. See
Gadfly.
