The Venus Flytrap, Dionaea muscipula is a small, carnivorous plant that catches and digests insects. The plant's leaves (terminal lobes) have tiny hairs, which trigger the trap to close when an insect comes close.
The trapping mechanism is so specialised that it can distinguish between living prey and non-prey stimuli such as falling raindrops.
These are treated as house plants here in the UK and many people keep them in the hope they will keep flies at bay.
Venus flytraps like to be kept moist.
Always use rainwater or filtered water rather than tap water.
Keep out of direct sunlight.
Please note that these plants are small, they are naturally low-growing and not huge traps as some people imagine!
