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.
