Venus Fly Traps are the classic carnivorous plants which trap insects using its hinged leaves. They need to be constantly damp and if grown in a pot then they need to stand in a dish of about 1cm of water all the time. They must have very bright light and do well on a sunny windowsill. Keep cool during the winter otherwise the plants will gradually decline. Venus Fly Traps will not tolerate hard water and should be watered with rain water or soft water. Their use in the terrarium is limited as they need to be damp all the time, but in a palludarium they are ideal growing near the water, providing the light is bright enough.
