How do Venus flytraps work?
Discover how these plants lure their prey.
Venus flytraps, like the rat-eating carnivorous plant, develop in marshy soils that are low in nutrients, so they need to find another source of food to maintain them, namely the pests that land on their leaves. These leaves are about eight to 15 cm long and are edged 'hinged' along the midline with shiny teeth around the edges. Folding and trapping is triggered by pressure on six sensitive hairs, which when stimulated will close the leaf.
In about half a second, though the actual nature of the action is still being debated. Along with these sensitive hairs, there are also glands on the leaf surface that secrete a sap that digests the body of the insect. This process takes about ten days, after which the leaf reopens.
