   moscafly, L. musca. Cf. {Musket}.] (Zo["o]l.)
   Any one of various species of gnats of the genus {Culex} and
   allied genera. The females have a proboscis containing,
   within the sheathlike labium, six fine, sharp, needlelike
   organs with which they puncture the skin of man and animals
   to suck the blood. These bites, when numerous, cause, in many
   persons, considerable irritation and swelling, with some
   pain. The larv[ae] and pup[ae], called wigglers, are aquatic.
   [Written also {musquito}.]

   {Mosquito bar}, {Mosquito net}, a net or curtain for
      excluding mosquitoes, -- used for beds and windows.

   {Mosquito fleet}, a fleet of small vessels.

   {Mosquito hawk} (Zo["o]l.), a dragon fly; -- so called
      because it captures and feeds upon mosquitoes.

   {Mosquito netting}, a loosely-woven gauzelike fabric for
      making mosquito bars.
