    oestrus ovis
    [ noun ]
    larvae are parasitic on sheep
    <noun.animal>


    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.

    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}.

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

    OEstrus \[OE]s"trus\, n. [L., a gadfly; also, frenzy, fr. Gr. ?
    gadfly; hence, sting, fury, insane desire, frenzy.]
    1. (Zo["o]l.) A genus of gadflies. The species which deposits
    its larv[ae] in the nasal cavities of sheep is {[oe]strus
    ovis}.

    2. A vehement desire.

    3. Specifically: (Physiol.) The periodical sexual impulse of
    animals; the period during which female animals are most
    receptive to males; heat; rut.
    [1913 Webster +PJC]
