flytrap \fly"trap\ (fl[imac]"tr[a^]p), n.
   1. A trap for catching flies.
      [1913 Webster]

   2. (Bot.) A plant {(Dion[ae]a muscipula)}, called also
      {Venus's flytrap}, having two-lobed leaves which are
      fringed with stiff bristles, and fold together when
      certain sensitive hairs on their upper surface are
      touched, thus trapping insects that light on them. The
      insects so caught are afterwards digested by a secretion
      from the upper surface of the leaves. The plant is native
      to North and South Carolina, growing in bogs.
