Butterwort Catches Insects
The Common Butterworts belongs to the 'fly-paper' group of carnivorous plants. As the habitat where it grows is so poor in nutrients it has developed its art in catching insects. Butterwort has sticky leaves which catch and digest insects.
The leaves curl over insects and glands on the leaf secrete enzymes which digest the soft parts of their prey.
The leaves of the butterwort are green or yellowish in colour. The leaves are thick and covered in glands which give off a slight smell which attracts the prey. The leaves also curl upwards slightly to try to avoid it's prey being washed off by the rain.
The insect lands on the leaf of the butterwort and becomes stuck on the glands. The leaf may curl over slightly in an attempt to increase the surface area contact with the insect.
The prey are small flying insects whose wings catch in the slimy substance on the leaves. The insects are probably dead by then, having died of suffocation when their respiratory spiracles became glued up. |

Crawling insects can normally escape this sticky end however. begin the slow process of digesting them with the help of acid-containing glands. The insects are probably dead by then, having died of suffocation when their respiratory spiracles became glued up.
The leaves once having caught the insects are actually discarded - especially if they have been successful in catching a lot of insects.
