Nepenthaceae is a kind of herbaceous plant that has the ability to prey on insects. In nature, Nepenthes often grow on their back. The structure of their leaves is complex. They are divided into petioles, leaf bodies and tendrils. The tail of the tendrils expands and rolls back to form bottles, which can prey on insects. pitcher plants have racemes of small green or purple flowers. The pitcher plant on the top of pitcher plant's leaf is a tool for catching insects. Nectar can be secreted from the opening edge and the covering surface of the bottle cap to attract insects. The mouth of the bottle is smooth. When the insect slips into the bottle, it is drowned by the liquid secreted from the bottom of the bottle, decomposes the nutrient substance of the insect body, and gradually digests and absorbs it.
Botrytis belongs to the genus Botrytis in the family botryaceae. Their tubular leaves can secrete digestive fluid, which, when mixed with the stored rainwater, can make the insects trapped in the tube fester. In other words, they use leaves to catch and digest ants, wasps and other insects. Botrytis usually uses honey to attract insects. On the insect catcher of Sargassum, there are many nectaries near the mouth of the bottle, which can secrete juice containing fructose to attract insects. When insects eat this kind of venom, they will be delirious, or paralyzed and die.
As a kind of vascular plant, Venus flytrap is a popular insectivorous plant with complete roots, stems, leaves, flowers and seeds. Its leaf is the most important and obvious part, which has the function of preying on insects. It has obvious bristles and red sessile glands, and looks like a big mouth with teeth and claws. Potted plants can be used for viewing on the window sill and balcony, or they can also be specially used for cultivation in the planting trough; flytrap is known as the natural carnivorous plant.
Plants rely on Photosynthesis of chlorophyll to produce nutrients, but a small number of plants can eat insects to absorb nutrients. This kind of insectivorous plant can catch insects, and then secrete liquid to digest and absorb the nutrients of insects.
Jindiluo is a kind of insectivorous plant, which often grows on the grassland or on the wet rock and sand. The leaves of jindiluo lie on the ground in the shape of a rosette, with broad spoon like leaves and long glandular hairs on the edge. When the insects fall in, the glandular hairs surround the insects, and the sticky glands stick the insects. The secreted liquid can decompose the nutrients such as the proteins of the insects, which are then absorbed by the leaves.
The insectivorous plants in the water are the species of Castanopsis family. Except for the inflorescence, all of Castanopsis aurea are submerged in the water. There are egg ball catching cysts on the leaf organ, which can catch tiny insects or zooplankton in the water. In summer and autumn, the inflorescence protrudes out of the water to produce yellow labiate flowers.
Earwort is a kind of insectivorous plant of castoridae, which grows in swamp and wetland. It is an annual dwarf herb with erect stem and creeping branches. The insect catcher is on the creeping branch of leaf organ. Because of its insectivore, there is no large leaf with chlorophyll, and there are several small yellow flowers on the top of the branch, and the calyx in the fruit period is enlarged and drooped in the shape of ear digging spoon.
