China has found the smallest dragonfly individual in the world, what is its growth environment?

Dragonflies are insects that are often seen in everyday life. But in our country, the smallest dragonfly in the world has been found, and its length is only 15-16 millimeters, which is about the same as people's fingernails. This species of pygmy Xiaoqing population is found in the Jinkouhe area of Leshan, Sichuan, which is a canyon mountain area, the mountain range is about 3,000 meters high, but at an altitude of 500 to 800 meters, it belongs to the tropics, because of the isolation of the mountains, so that the population of pygmy Xiaoqing has no way to breed with other dragonflies, so they can only evolve independently, forming this tiny size.

1. China found the world's smallest dragonfly among the insect specimens in the Chengdu Huaxi Museum, there is a kind of dragonfly specimen that is particularly eye-catching, their size is very short, the male dragonfly has a body length of only millimeters, and the female has a length of 16 mm, of which the smallest male dragonfly is not more than 15 mm long. If one compares the smallest dragonfly on a finger, it is the size of a fingernail. You know, if you compare the torso of the body, the body of the longest variety, Lucretia Giant Damself, can be as long as a centimeter.

This dragonfly is the smallest species of dragonfly and is called Pygmy Xiaoqing. It is also the smallest dragonfly species in the world.

Second, the unique geographical environment caused by the dwarf Xiaoqing is recognized by experts as the smallest dragonfly species in the world, they mainly live in Southeast Asia and southern China, and belong to the "dwarf" among the dragonfly species. According to Zhao Li, the director of the museum, this kind of pygmy Xiaoqing is now known to everyone to live in the northernmost region of China, and this species is a species that has evolved separately. Because in the Jinkou River in Leshan, Sichuan, its earth is a high mountain valley area, and the surrounding mountains of the canyon are as high as 3,000 meters, but at the bottom of the canyon at an altitude of 500 to 800 meters, it belongs to the isolated tropical climate.

Therefore, due to the barrier of high mountains, these dragonflies cannot reproduce with outside races, so they can only evolve independently into the current small population.

Because of the unique geographical environment of this alpine valley, this species of pygmy Xiaoqing has no way to communicate with dragonfly species in other regions, so it can only evolve independently, and it does not evolve gradually, so it has formed a population of pygmy Xiaoqing that is different from other dragonflies that people see now。I have to say that everything in the world has its reason for existence, and nature is very great. Now people have found more than 5,000 species of dragonflies in the world, and nearly 1,000 species have been found in China, which can be said to be the country with the largest number of dragonfly varieties in the name.

China has found the smallest dragonfly individual in the world, and its growth environment is also very rich in water resources in some relatively humid paddy fields, and the temperature is relatively high.

Our country has found the smallest dragonfly individual in the world, and its growth environment is like this, he likes to live in a hot environment, and it is because of this special environment that it will evolve into such a dragonfly.

Its growing environment is actually a little different from that of ordinary dragonflies, and it belongs to a relatively hot area.

China has found that the smallest dragonfly individuals in the world grow in high mountains and valleys, and it is precisely because of this special geographical environment that they can evolve into such small individuals.

Based on the special structure of the dragonfly's "compound eye", human beings invented phased array radar. As the speed of the aircraft continues to increase, the wings of the aircraft are shattered due to violent shaking. After research, scientists found that the dragonfly has a slightly heavier object at the end of its wings, which keeps the plane balanced.

Dragonflies have a lot of flying stunts. In flight, they often take turns vibrating their forewings and hindwings, and suddenly they glide with their wings straight. Occasionally, only the front wings vibrate, while the back pair of wings are calmly extended.

Dragonflies can not only fly forward, but also backwards.

They vibrate their wings and stay in the air for a short distance, even when hunting prey, and they can fly vertically for short distances. However, when flapping their wings, they can also experience harmful flutter. Nature has given them the means to eliminate this harmful phenomenon.

It is not difficult to find that above the leading edge of each wing of the dragonfly, there is a thickened dark cuticle - the wing eye (wing nevus), which is their special device to eliminate the hidden danger of flutter. Although dragonflies will not lose their ability to fly if they remove their wing eyes, it will affect the correctness of wing vibration, making their flight wobbly and floating like "drunks".

People were inspired by this, and an invention was made to prevent flutter. A weighting device is placed on the leading edge of the wing end of the aircraft (the simplest is to weld a lead weight) and harmful vibrations are eliminated.

There are more than 5,000 species of dragonflies, but they vary greatly in size. The largest dragonfly in the world is the Australian dragonfly at 12 centimeters in length, and it is also the fastest flying insect in the world. The smallest dragonfly in the world is the small pygmy dragonfly that will be introduced in this article, with a body length of less than 2 centimeters.

This dragonfly has a bright body color, especially for males, and looks very pleasing to the eye.

As its name suggests, the baby dwarf is the dwarf of dragonflies, the smallest of the dragonfly species found so far, with adult males generally around millimeters in length and females generally around millimeters. The males and females of this dragonfly have different body colors, with males having bright red bodies including their eyes, and females being yellowish-brown.

They are mainly found in Australia and many countries in Southeast Asia, and can also be found in Guangdong, Zhejiang, Hong Kong and Taiwan, where they prefer to inhabit grassy wetlands, rice paddies or ponds.

Unlike most dragonflies that are highly skilled at flying, the baby pygmy dragonfly is not very good at flying, so it has a small range of activities, concentrating on a small area in a suitable location for feeding and breeding. Although they have a petite body size that is easy to hide, they are easy to spot by eaters due to their bright body color, especially in males, and the obvious contrast to the environment in which they are active.
