Dragonfly, invertebrate, Insecta, order Odonata, Asteroptera A general name for insects. Generally, the body shape is larger than that of Xi, with long and narrow wings, membranous, and extremely clear reticular wing veins. The vision is extremely sensitive, with 3 single eyes; 1 pair of thin and short antennae; chewing mouthparts. The abdomen is elongated, flat or cylindrical, with an anal appendage at the end. The legs are thin and weak, and have hooks on them to catch pests while flying in the air. The larvae of the water hyacinth breathe through the rectal trachea and gills in the water. Generally, it needs to molt more than 11 times, and it takes 2 or more years to climb out of the water along the aquatic plants, and then undergo the final molt to emerge as an adult. Larvae can prey on larvae or other small animals in the water, and sometimes cannibalize their own kind. In addition to large numbers of mosquitoes and flies, adults can also prey on butterflies, moths, bees and other pests, and are indeed beneficial insects.

The general name for all insects of the order Odonata. Including the familiar dragonflies and damselflies. The larvae are called nymphs, are completely aquatic, and have completely different shapes and habits from the adults. The morphology of various larvae varies greatly. Adult insects have two pairs of narrow and transparent wings of equal length, with a network of veins, and there are often wing nevus on the front edge of the wings near the top of the wings. Chewing mouthparts are well developed. The chest is arranged obliquely, and the front chest is small and mobile.
The legs are close to the head (to facilitate hunting). The abdomen is elongated. The compound eyes are prominent and the antennae are small and not obvious. Although the structure of the adult insects is quite the same, their sizes vary greatly. The wingspan is generally 5 centimeters. Dragonflies dance on lotus leaves
From the smallest 1.8 centimeters (0.7 inches) to the largest 19.3 centimeters (7.5 inches). Dragonflies are the insects with the most eyes in the world. The dragonfly's eyes are large and bulging, occupying most of the head, and each eye is composed of countless "small eyes". These "small eyes" are connected to photoreceptor cells and nerves, and can distinguish the shape of objects. For their size, they have excellent eyesight and can look up, down, forward, and backward without turning their heads. In addition, their compound eyes can measure speed. When an object moves in front of the compound eye, each "small eye" reacts in turn, and after processing, the moving speed of the target object can be determined. This makes them the masters of insect hunting.
Edit this section for distribution
Common dragonflies such as blue-faced dragonflies are mostly distributed in Zhejiang, Sichuan and other provinces; green dragonflies with long moles are distributed in North China; yellow dragonflies are distributed in many provinces across the country ; The Jade Belt Dragonfly is only produced in China and is mainly distributed in Beijing, Jiangsu, Fujian and other provinces and cities.
Edit this paragraph about literary and artistic works
The famous poet Yang Wanli of the Song Dynasty wrote a poem "Little Pond" with dragonflies as the theme: "The spring is silent and cherishes the trickle, and the shade of the tree shines on the water and loves the clear and soft water. Little Pond" The lotus has just revealed its sharp corners, and a dragonfly has already stood on it." Zhu Xuanxian, an outstanding artist in modern times, created the Chinese painting "Little Lotus Revealing Its Pointed Corners" based on this, which vividly and vividly reflects the poetic and picturesque atmosphere composed of dragonflies, nature and people.
Edit this paragraph’s living habits
Dragonflies generally fly around ponds or rivers, and their larvae (larvae) develop in the water. Predatory, adults prey on flying insects in flight. Mosquitoes and other insects are harmful to humans. Dragonflies (edited by Su Zhihe)
[1] However, they have a wide range of food habits, so they cannot be relied on to specifically prevent and control certain insect pests. No more than 5,000 species are known. The larvae breathe through gills. It is often motionless, and when prey approaches, it shoots out its curling lips to capture it. Molts 8 to 15 times during development. The number of molts varies within and between species. There is no pupal stage. A few minutes after hatching from the egg, the sheath-like skin of the first instar larvae splits, releasing the spider-like second instar larvae. The early instar larvae feed on aquatic animals such as small crustaceans and protozoa; The insects feed on chironomid larvae, aquatic beetles and snails, and even small fish. Wing buds appear early and grow as the number of molts increases. By the time the larvae reaches the last instar, the organs of the adult worm have formed in their bodies. After a few days, the larvae crawl out of the water, shed their skin and emerge as adults (eclosion). The largest dragonflies usually leave the water after sunset and take off before sunrise, so their emergence is rarely seen. Smaller species emerge during the day. The newly emerged adults have soft bodies, immature reproductive systems, and undeveloped color. One of its first activities was flying out of the water. The life of an adult insect is divided into two stages: one is the pre-reproductive period, which lasts about 2 days to 2 weeks, depending on the species and climate; the other is the reproductive period, which lasts about 1 to 6 weeks. Feed actively during the first stage and stay away from water. The second stage begins with sexual maturity, when the dragonfly flies to a mating site (usually a pond or river where eggs can be laid). The males arrive a little earlier, take up a position along the river bank or water surface, and defend their territory like birds do, driving away other intruding males. If a female flies close to or into the area, the male will attempt to mate with her. A few species perform courtship displays before mating. The mating posture is unique. The male uses the gripper at the end of the abdomen to hold the female's head or chest, and uses its movements to induce the female to bend her abdomen forward and contact the mating organ at the base of the male's abdomen. When mating, they usually land on the ground, but it can also be done in the air. Mating lasts from seconds to hours. The female lays eggs immediately after mating, or several hours or days later. There are two ways of laying eggs. Species with well-developed ovipositors lay their eggs in or on water or plant tissue above the water. Some climb to the surface of the water to lay eggs, and can be immersed in water for more than an hour. Species without ovipositors wash their eggs from the end of the abdomen and drop them on the water. Several species lay their eggs in flowing water, but have adhesive or entangled devices that prevent them from being swept downstream. Adults need warm climate, food and water suitable for laying eggs to reproduce. Fish and birds will prey on dragonfly larvae, and the larvae will also eat each other. When fledging, they may be preyed upon by birds and small crocodiles. However, the adults are almost harmless to enemies after leaving the place where they emerge. They fly quickly and flexibly and can avoid almost all enemies. Most species in temperate areas overwinter as larvae. The larval stage can last for 1 to 5 years, and the adult stage only lives a few weeks. Emerging adults vary in color, ranging from metallic to pink. Compared with other insects, they are large, with some having a wingspan of 16 centimeters (about 6 inches), and even the smallest species has a wingspan of 2 centimeters (0.8 inches). In addition to being extremely agile flying animals, they are also among the fastest insects. Dragonfly wing muscles function best when it's warm, and if it's cool, the insect often flaps its wings to generate heat before actually taking off. The dragonfly's speed and agility make it the most efficient flying predator. Prey is usually small flying insects, but some dragonflies often eat up to 60% of their body weight in prey. Young dragonflies—called larvae, which undergo a hemi-metamorphosis of incomplete metamorphosis, sometimes called larvae—are aquatic, as specialized predators in the water as adults in the air. Functionally wingless larvae are often mottled or dull in color, matching the color of sediment or aquatic vegetation in their environment.
Their protruding eyes are similar to those of adults, but they have striking anatomy that adults lack. This is called a "mask" and is a fusion of the larvae's third pair of mouthparts. The mask was disproportionately large and tucked under the head and throat when not in use. At the end of the mask is a set of tooth-like clips used to catch prey such as worms, crustaceans, tadpoles, and small fish. Different types of dragonfly larvae are called larvae, burrowing worms, cryptozoans or pinworms respectively - their body shape, metabolism and respiration depend on the micro-habitat in which they live. Larvae from water or water Libellula forensis, a species of dragonfly.
The eggs crawl out from the side, and there are three ways to produce eggs. Some species lay their eggs in plant tissue, while others adhere to the bottom layer of surface water or on top of it. Eggs may also fall from the abdomen or be washed into the water. The larvae use gills in their rectum to absorb oxygen from the water. The abdomen sucks water in and presses it out through the anus. Water may be vigorously expelled in this manner, creating a jet-propelled method of escape. Solid waste is also discharged in this manner. As the larvae grows, it sheds its skin, and its future wings first become apparent about halfway through the larval growth period. These elytra then rapidly enlarge during the subsequent molt. Finally, the larvae crawl out of the water (sometimes at night) and undergo a final molt to become adults, leaving behind a skin (molt) that is the shell of their former body. Dragonfly mating also takes place in flight. The male dragonfly uses the hook at the end of the abdomen to grasp the female dragonfly's neck; the female dragonfly's abdomen bends forward from bottom to connect the genital pore to the sperm storage organ under the second segment of the male dragonfly's abdomen, and then the male dragonfly performs insemination. Why do dragonflies touch water with their tails? The dragonfly is different from many other insects in that its eggs hatch in water and its larvae also live in water, so when it touches water, it actually lays eggs. Female dragonflies lay eggs in the water. Most of them touch the water with their tails while flying and expel the eggs. The common so-called "dragonfly touching water" is its performance when laying eggs. Dragonfly eggs are yellow. Dragonfly Spots Water

Dragonflies can be divided into the suborder Hyoptera of dragonflies and the suborder Homoptera of damselflies. The Japanese giant green and the only two species of dragonflies found in India are classified into the suborder Mesopterygium, which are also very primitive insects in the suborder Pterozoa. The dragonfly has well-developed wings, and the front and rear wings are equally long and narrow; the head can be flexibly rotated, the antennae are short, the compound eyes are well-developed with three single eyes, and the chewing mouthparts are powerful. The male copulatory apparatus is located on the second and third abdominal segments of the abdomen. Incomplete metamorphosis, the larvae "water flies" live in the water and hunt for food with their extremely developed faces. Both adults and larvae are carnivorous and eat many pests. There are about 5,000 species, about 300 species in China. There are many common dragonflies: such as Biwei dragonfly, yellow dragonfly and long-leaf dragonfly. These three kinds of dragonflies basically represent various families of the order Odonata, that is, they represent Large dragonflies, medium dragonflies and damselflies. They are generally larger in size, with long and narrow wings, membranous, and extremely clear meshed wing veins. They have strong flying capabilities, up to 10 meters per second. They can turn suddenly, go straight into the sky, and sometimes fly backwards. When resting, the wings are spread flat on the sides or upright on the back. The forewings and hindwings are not similar, and the hindwings are often larger than the forewings. There is a wing nevus on the front edge of the wings near the top of the wings, which is rectangular or square in shape, which can maintain the regularity of the vibration of the wings and prevent breakage due to tremors. The head can rotate flexibly. It has one pair of large compound eyes, accounting for about 1/2 of the head. It is composed of more than 28,000 small eyes. It is the animal with the most "eyes" in the world. The vision is extremely sensitive, with 3 single eyes; 1 pair of thin and short antennae; chewing mouthparts. The abdomen is elongated, flat or cylindrical, with an anal appendage at the end. The legs are thin and weak, and have hooks on them to catch pests while flying in the air. Like to fly back and forth at low altitude before it rains. Male and female mating also takes place in the air. Most female insects "point" their eggs in the water multiple times while flying on the water, and some insert their abdomens into shallow water to lay eggs at the bottom. The larvae of the water hyacinth breathe through the rectal trachea and gills in the water. Generally, it needs to molt more than 11 times, and it takes 2 or more years to climb out of the water along the aquatic plants, and then undergo the final molt to emerge as an adult. Larvae can prey on larvae or other small animals in the water, and sometimes cannibalize their own kind. In addition to large numbers of mosquitoes and flies, adults can also prey on butterflies, moths, bees and other pests, and are indeed beneficial insects.
