You may think that it's terrible to eat animal plants. In fact, it's all due to our fear of unknown things that we don't understand. Maybe you don't know that there are many insect eating plants around you, but you don't pay attention to them. If you try to understand them, you may be surprised. Let's take a look at some common insectivorous plants.
There are also insect eating species in plants. What is insect eating animal? Insect eating plant is a kind of autotrophic plant that can capture and digest animals to obtain nutrition (non energy). Most of the prey of insectivorous plants are insects and arthropods. It grows in poor soil, especially in areas lacking nitrogen, such as acid marshes and rocky desertification.
Insectivorous plants, which can attract and catch prey, produce digestive enzymes and absorb nutrients, are distributed in 21 genera of 10 families, with more than 630 species. In addition, there are more than 300 genera of plants with insect catching function, but they do not have the ability to digest prey, so they can only be called insect catching plants. Some pitcher plants can occasionally prey on small mammals or reptiles, so insectivorous plants are also called carnivorous plants. What are the insectivorous plants?
The fly catcher (Dionaea) belongs to the family Caesalpiniaceae, only one species in the genus, namely, Dionaea muscipula, but there are many cultivated varieties, native to the state of Carolina in the United States, most of which are in wetlands or swamps. The trap of flycatcher has the ability of activity, and the process of catching is very interesting. It is loved by people, and has become the most favored insectivorous plant species in China. The catching process of flycatcher is probably the most peculiar among all insectivorous plants, with the most complicated mechanism. The predatory structure of the flytrap is a clip formed by a left right symmetrical leaf. The clip like structure is specialized from the leaf. As for the structure connecting the leaf of the insect catcher, it is the petiole. The outer edge of the trap is lined with prickly hairs. At first glance, they are sharp and can stab people, but in fact, these hairs are very soft. The function of these hairs is to prevent captured insects from escaping. 2. Maogaocai
One of the plant insectivorous plants of the genus Caesalpinia, which belongs to the family Caesalpiniaceae. There are about 100 species of plants of the genus Drosera, which are distributed in Oceania, North Africa, Europe, America, Southeast Asia and Australia, and a few in the cold zone. There are six species in China. Except one species in Northeast China, the others are all in coastal areas such as provinces, regions and Taiwan Province to the south of the Yangtze River. It is also a carnivorous plant. There is an obvious stem in the caesalpine, and there is a small glandular hair in the stem. Glandular hair can produce a kind of viscous liquid. This kind of viscous liquid is used to catch insects. 3. Pitcher
Pitcher is a famous tropical insectivorous plant. Its main producing area is tropical Asia. The cage grass has a unique organ to absorb nutrients - the worm catcher. The worm catcher is cylindrical, and the lower part is slightly expanded. Because the shape is like a cage, it is called the cage grass. Hainan, the birthplace of China, is also called Lei Gong pot, which means it is like a wine pot. This kind of plant is called insectivorous plant, which does not directly absorb and produce the nutrients needed to maintain life from soil and other inorganic communities, but relies on catching insects and other small animals to make a living. There are nectaries in the larval sac of pitcher grass that can secrete nectar to attract insects. After insects enter the larval sac, the lid of the sac is not closed as people think, but the inner wall of the sac is very smooth, so it can prevent insects from climbing out. 4. Sargassum
Sarracenia belongs to the genus Sarracenia in the family Sarracenia, which is native to Western Europe, North America and Mexico. Because they can secrete digestive fluid in their tubular leaves, mixing 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. The anatomical structure of Sargassum odoratum is a perennial herb. From the growth point of the underground stem, a rosette like leaf grows. The leaves are divided into two parts: the one with insect filling function and the one without insect filling function. 5. Felt moss
Felted moss is a kind of thatch, mainly grows in the sandy acid soil in the humid and swampy area. The flowers are small, white or light pink, with a diameter of 1.25 cm at most. The leaf margin is flat, and the surface of the leaf is covered with a layer of glandular hair. The gland secretes a kind of slime that attracts insects. When the insects are attracted to eat, they are caught by the curving hairs on the leaf surface, and then the leaf mat rolls, After digesting the enzyme, the leaves open again. 6. Catching insects
The insect catcher is a small insectivorous plant with soft temperament. Its leaves are as beautiful as a blooming flower. The leaves are covered with glands that can secrete mucus. When there are small insects near, they can stick the insects like sticky paper, digest and absorb them. The colorful flowers of cordiery are easy to attract insects. When the flying insects fall on the leaves, they will be stuck by mucus. Of course, the stuck insect is not willing to be caught, it will struggle desperately, so the leaf edge will curl inward and wrap it inside, unable to escape. In this way, insects fall into the clutches of corydalis. 7. Nutria
The most representative aquatic plant in the genus nutriaria. The plant is emerald green or yellowish green. It has a soft and thin main stem axis of more than 100 cm long, and then branches from both sides of the stem axis and beautiful pinnate lobes grow in the branches. The color of its feeding sac is usually green to yellow green, which can catch and digest microorganisms in water. Because its pinnate, needlelike leaves are dense and slender, and the grass is beautiful, it is very suitable to be used as a kind of nutria for waterscape, but when planting, we must try to fix the bottom stem. It can adapt to the environment of aquarium and grow rapidly. In a short time, aquarium may be full of aquarium, so it must be pruned regularly. 8. Miandiluo
It is the whole plant of broccoli in the family of maogao. It 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. A family of dicotyledonous plants of the subclass gymnospermae. 9. Soil bottle grass
Earth bottle grass: also known as Australia bottle grass. The only species of cephalotaceae, native to southwest Australia. Herbs perennial, with short woody underground stems. The flower is light yellow, and its lower leaves are bottle shaped, used to catch insects. Passive bag trapping. The capsule lid does not move. The bag and cover are purple red in strong sunlight, and the transparent window on the bag cover attracts insects. There are glands inside the bag, and the bag mouth is slippery. Insects can easily fall into the bag when staying on the outer edge of the bag mouth. They are drowned by the liquid in the bag and digested and decomposed by the digestive liquid. 10. Ear digging grass
Ear digging grass, synonymous with Yuncao, maoyecao (native grass of Southern Yunnan), wild tobacco, wild thinking grass (convenient formula for plants and plants), wild tobacco (classified herbal nature), inverted pot (empirical identification method for shape of traditional Chinese Medicine), golden ear (records of Sichuan Traditional Chinese Medicine), wild sunflower, liushicao, maoyeyuncao, and wild Chaoyang stalk (Yunnan Traditional Chinese Medicine). It is the whole grass of the Compositae. It is an annual herb. There are no obvious creeping branches and leafy organs on the underground branches; the whole plant has no green leaves and does not support photosynthesis; the insect catcher is located on the leafy organs and creeping branches, spherical, flattened and feeds on micro animals in wet land. Racemes on the ground, bracts brownish red, flowers yellow. It often grows on wet grass. There are many provinces in Southeast and southwest China.
