Flytrap \Fly"trap\, n.
   1. A trap for catching flies.

   2. (Bot.) A plant {(Dion[ae]a muscipula)}, called also
      Venus's flytrap, the leaves of which are fringed with
      stiff bristles, and fold together when certain hairs on
      their upper surface are touched, thus seizing insects that
      light on them. The insects so caught are afterwards
      digested by a secretion from the upper surface of the
      leaves.
