It needs to be supplemented with food, which can be legs or wings of some insects. But the frequency of feeding does not need to be too high. If you plant outdoors, don't worry about the lack of food. You can also add some fish with strong taste to the potted plants to attract insects, so that the flytrap will hunt and eat by itself.
It grows a trap, which is specially used to catch flies or small insects. Its clip is about 3cm long, but when the clip catches prey, if the insect is too big, it will be easy to break free. Its catching principle is that when the insect touches the sensitive part of the clip, the clip will automatically close, and the insect will struggle inside after being caught, so the flytrap will digest. After a few hours of this process, when it is digested, it will naturally open its clamp and wait for the next prey. But in general, a plant can not catch several insects, so we need to pay attention. Also need to pay attention to is, after the plant digests, need to clean its clamp, lest cause the plant not beautiful.
