  1. Dragonfly's mating is also carried out on flight. The male dragonflies use the hook -shaped object at the end of the abdomen to seize the neck of the female dragonfly; the female dragonfly bends from the bottom to the front, the reproductive hole is connected to the storage sperm organs below the second section of the male dragonfly abdomen, and the male dragonfly is inseminated. The female dragonflies lay their eggs into the water, and most of them use the tail to touch the water surface when flying, and lift the eggs. The so -called "dragonflies" we have commonly used is its performance when spawning.

    The dragonflies (scientific name: Dragonfly), alias, lights, ants, dragon family, family animals, pupae. Common dragonflies such as blue faces are distributed in Zhejiang, Sichuan, Guizhou and other provinces. Long moles and greenflies are distributed in North China. The jade belt dragon is only distributed in Beijing, Jiangsu, and Fujian.
    The dragonfly is generally larger, wings are long and narrow, 3 single -eye, 1 pair of tentacles, thin and shorter, chewing mouth, slender abdomen, flat or round cylindrical, the end has anal attachment, the end has anal attachment, the end has anal attachment, the end has anal attachment, the end has anal attachment. Fine and weak, there are thorn. The larvae (lady) develops in the water. It is generally molted with rectal tracheal gills in the water. Generally, it takes more than 11 or more. It takes 2 or more than 2 years to climb the water along the water plants, and then the final molting feathers into adults.

    Dragonfly

    A dragonfly discovered in India is only two types of dragonflies classified as the purpose of wings. Large insects are also the most primitive insects in wingedian. Wings are developed, and the front and rear wings are long and narrow; the head can rotate flexibly, with short tentacles, and developed eyes. There are three monocular, and the chewing portion is powerful and powerful. The male mate is located on the abdomen two and three verses. Instead of perverted, larvae "water" lives in water and prey with a strong face. Both adults and larvae are carnivorous and eat more pests. There are about 4,500 species.

    The general body size, long and narrow wings, membrane, mesh wings are extremely clear, and the flight ability is very strong. It can reach 10 meters per second. Sometimes you can return to fly back. During the rest, the two wings are flat on both sides, or stand on the back. The front wings are not similar to the posterior wings, and the posterior wings are often greater than the front wings. The front edge of the wings, near the top of the wings, each with a winged mole, which is rectangular or square, which can maintain the regularity of the wings and prevent injuries from tremor. The head can rotate flexibly, with 1 pair of compound eyes, large, accounting for about 1/2 of the head, which is composed of more than 28,000 small eyes. Visual is extremely sensitive, 3 single -eye; 1 pair of tentacles, thin and short; chewing port. The abdomen is slender, flat, or a cylindrical shape, with anal attachment at the end. Film and weak, with hook thorns, can capture pests when flying in the air. Before the rain, please fly round trips at a low altitude. The end of the male and female is also carried out in the air. When most females are flying on the water, they "point" the eggs in the water multiple times, and some also insert the abdomen into the shallow water to produce eggs under the water. Anemone water, breathe with rectal tracheal gills in water. Generally, it is necessary to molt more than 11 times. It takes 2 or more than 2 years before climbing out of the water on the water plants, and then turns into adults through the final molting feathers. Anemia can prey in water or other small animals in water, and sometimes the same type is also disabled. In addition to a large amount of mosquitoes and flies, adults can also prey for pests such as butterflies, moths, bees, etc., which is really a pest.

    M common dragonflies such as blue faces are mostly distributed in provinces such as Zhejiang, Sichuan and other provinces; long moles and greenflies are distributed in North China; Yellow Dragon Dragons are distributed in many provinces; In Beijing, Jiangsu and Fujian provinces.

    The dragonfly flys quickly, some flying speed can reach 100 kilometers per hour, and it can stop in the air short. It cannot change the direction flexibly when it is flying. When resting, the wings are still extending, that is, the wings cannot be folded, so there must be a considerable space for the place where the stay is, mostly on the branches or leaf tops.

    The mating of the dragonfly is also carried out in flight. The male dragonflies use the hook -shaped object at the end of the abdomen to seize the neck of the female dragonfly; the female dragonfly bends from the bottom to the front, the reproductive hole is connected to the storage sperm organs below the second section of the male dragonfly abdomen, and the male dragonfly is inseminated. The female dragonflies lay their eggs into the water, and most of them use the tail to touch the water surface when flying, and lift the eggs. The so -called "dragonflies" we have commonly used is its performance when spawning.

    The dragonflies (leaves one text)

    dragonflies, no long feathers, thin and transparent wings are enough to divide the world with small birds of flesh and blood.

    The soaring function of Dragonfly is far better than birds.

    The body shape is very similar to the aircraft created by humans.

    The dragonfly used to be a large family. It is also closest to our human beings. It is on the road and freely shuttle and stop in the countryside. Once upon a time, it also hid with the little urchins in front of the house in front of the house.

    The dragonfly is beautiful and cute! Dragonfly is simple and hardworking!

    The dragonfly a little water with a trembling figure is "producing eggs". The instinct of fertility continues, it is also so rhythmic and wonderful. In between, any praise will be inferior to it. As a result, we should thoroughly rehabilitate the traditional "dragonfly water".

    . Unfortunately, our good desire may be a empty words, and the lack of human morality is written!

    In you, with the rapid growth of humans, the variety of the Dragonfly Family is extinct one after another or is extinct ... In our living area, how many dragonflies are left to dance with us. On our heads, you can still see a few dragonflies hovering. Poor dragonflies are killed in catastrophic "pesticides" in the magic weapon of human beings. How many years can the surviving survivors spend more years in a harsh environment?

    If the butterfly is dying, there are moths are close relatives. The moths are changed by insects, and the vitality of the worms is particularly strong. The "pesticide" of our human beings is helpless. This bug seems to kill more and more. If the dragonfly dies, it seems that there is nothing to replace it. In terms of its wings, the wings of the dragonfly are unique. In contrast, dragonflies can be regarded as replica of human aircraft.

    This and mantis hiding in the grass, the time of jumping and crawling is small and short, and the shape of its wings is different from that of the dragonfly. The wings of the cicada are the most similar to the dragonfly, but its short figure is far as long and beautiful as the dragonfly. The mosquito flies and the ugly face should not be compared with the dragonfly. Only this dragonfly flew silently from morning to night, and it can bear the heat of the sun, and there is no need to drink water to drink tea. The camel living in the desert must also worship it.

    The mating map of the dragonfly is an extremely wondering geometric body. The arc ring made of two tails has a simple mystery and mystery. The most tacit combination, they can still turn up and down, glide forward, and rush left and right. The planes that we humans imitate cannot reach such artistic height.

    Sadly, the dragonfly sacrificed in the next batch of glory in the next batch of human prostitution. Its repeated poisoning and extinction are inseparable from the credit of mosquitoes. The brigade of the Dragonfly Family can contend with ants, but now it is rare than birds, which is really distressed!

    It in my small collection cabinet, a precious dragonfly specimen is saved: tentacles.

    The biggest feature of tentacles is that the head minister has a pair of tentacles. This pair of tentacles are about length as its body, which is harder. I clearly remember that when I caught it on the mountain, my whole body was dark red. The whole body was more petite than the common dragonflies, and it was alive like a "Xiuzhen woman" in the kingdom of dragonfly.

    This tentacles have been collected for ten years. I use paper and transparent tape to position it in a transparent plastic box. And protect its intact corpse and quality. I am also a part of human beings. I have a deep crime to it. I have the right to write a few words as our confession and memorial!

  3. Is doing business.
    The dragonfly is carnivorous insect. They prey on a variety of pests such as flies, mosquitoes, leaf cicadas, crickets, and small butterfly moths. Dragonfly is a type of important natural enemy insects that are beneficial to human beings. "Dragonfly" is the biological characteristics of the dragonfly produced in the water. Its larvae (lady) live in water, and the period of life varies from type. Flying is generally 2 years, and some of them have 3 to 5 years. [3] It can be used to monitor environmental pollution and have medicinal, consumption, ornamental value. The back of the back wings is slightly larger than the front wing base, and the wings veins are slightly different. During the rest, the four wings opened, flattened on both sides. The insect is short and thick, with rectal gills, no gills.
    The 3 general subjects including Flying Flying, Dafeng General Section, and Dragon General Section, a total of 11 subjects. Flye and dragon family are the most common, and they are widely distributed throughout our country. Types of Chinese dragonflies: Needham (1930-1932) In the "Chinese Dragonfly Handbook" and subsequent bookings, there are 283 types of dragonflies in my country. Hu Jingfu (1935) In the "Chinese Dragonfly List", the Chinese Dragonfly had 87 genus 308 species. Sui Jingzhi and Sun Hongguo (1986) The book "Chinese Said Dragonfly", with the Chinese dragonfly specimen collected by the Institute of Animal Research of the Chinese Academy of Sciences at the time, described 208 Chinese dragonflies.
    Davies et al. (1984--1985) "World Dragonfly Type List" is considered to be the most complete list of dragonflies around the world today. It includes more than 5,600 known dragonflies around the world. Among them, there are only more than 250 types of knowledge in China. Zhao Xiufu (1990) The Spring Flying Category of China describes 145 species of China Spring Fields 22.

  4. The egg breeding of the dragonfly and the larvae of the hatching are in the water, and they usually have dragonflies mating, but they are all carried out on the water.
    The dragonflies will mate together when it rains, so that the chance of survival in the larvae will be much higher. This is also the long -term survival habit of species
    The dragonfly is the most eye insect in the world. Dragonfly's eyes are big and drum, occupying most of their heads, and each eye has countless "small eyes". These "small eyes" are connected with sensor cells and nerves. The size, their vision is excellent, and they can also look up, down, forward, and backward without having to turn their heads.
    The dragonfly is different from many other insects. Its eggs are hatched in the water, and larvae also live in the water, so it is actually spawning. The female dragonflies lay their eggs into the water, and most of them use the tail to touch the water surface when flying, and lift the eggs. The so -called "dragonflies" we have commonly used is its performance when spawning. The egg's egg is yellow.

  5. Dragonfly's mating is also carried out on flight. The male dragonflies use the hook -shaped object at the end of the abdomen to seize the neck of the female dragonfly; the female dragonfly bends from the bottom to the front, the reproductive hole is connected to the storage sperm organs below the second section of the male dragonfly abdomen, and the male dragonfly is inseminated.
