My main Carnivorous plant groups

Sarracenias work by using slippery hairs to make the insect lose it's grip and fall into the tubular stem for digestion. Venus Fly Traps work by using hairs inside of the trap to sense when an insect has entered the trap so that it can encase them inside of it. Sundews work by using small droplets of a clear sticky liquid to stick their insects to them before digesting them.
