1.A trap for catching flies.
2.(Bot.) A plant (Dionaea 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.
