The Venus Flytrap (also Venus's Flytrap or Venus' Flytrap), Dionaea muscipula, is a carnivorous plant that catches and digests animal prey—mostly insects and arachnids. Its trapping structure is formed by the terminal portion of each of the plant's leaves and is triggered by tiny hairs on their inner surfaces. When an insect or spider crawling along the leaves contacts a hair, the trap closes if a different hair is contacted within twenty seconds of the first strike. The requirement of redundant triggering in this mechanism serves as a safeguard against a waste of energy in trapping objects with no nutritional value.
Dionaea is a monotypic genus closely related to the waterwheel plant and sundews, all of which belong to the family Droseraceae.

Famous quotes containing the word venus:
“In the drawing room [of the Queens palace] hung a Venus and Cupid by Michaelangelo, in which, instead of a bit of drapery, the painter has placed Cupids foot between Venuss thighs. Queen Caroline asked General Guise, an old connoisseur, if it was not a very fine piece? He replied Madam, the painter was a fool, for he has placed the foot where the hand should be.”
—Horace Walpole (17171797)
