Brief biography of a dragonfly

However, in life this is not so, since the flying "windmen" have amazing abilities and help a person, destroying blood -sucking insects. Observation of the behavior of the dragonfly is akin to meditation, as this completely captures, hypnotizes, allows us to abstract from the world around him. Since the insect is widely used, you can see a dragonfly in a variety of corners not only of Russia, but also to planets.

Dragonfly under a microscope watching a dragonfly, sometimes it seems that this is a drone launched by aliens to observe the inhabitants of the Earth. Large eyes resemble television cameras, the body serves as an antenna for the transmission of the television signal, silent wings provide secrecy. The course of the course is not limited. At least, this gives an impression when you see how easily, tired, the insect from place to place flies without tired.

The body of a dragonfly consists of a head, chest, abdomen and wings. A strong chitin cover serves as armor. The insect head is disproportionately large, which is usually associated with a great mind. It is able to turn along the longitudinal axis into degrees. However, this is also available to a person. Eyes have a complex facet structure. They consist of 28 thousand elements.

Some are responsible for the perception of color, others for the shape of the object. If you look closely, in the front of the head you can see the forehead and lips that cover the mouth gap. Dragonflies have jaws with sharp teeth that it easily grind food. The chest is divided into three parts, each has a pair of legs, and the middle and back are still equipped with vapors of wings.

Since the front and rear wings work independently of each other, this provides high flight speed and excellent maneuverability. The dragonfly has four wings. They are thin chitin planes covered with a network of thin veins. Dragonflies can make up to 15 waves wings per second! Try to do the same with your hands, and you will understand how difficult it is. The legs of dragonflies consist of several parts.

The top is a funny name of the basin. Below is a vertluoga, even lower - the thigh, then the lower leg, and the structure completes the structure. All parts are interconnected by mobile hinges. The legs cover small spikes. With such a complex device, a dragonfly used limbs mainly for planting. They can use the first pair of legs instead of hands, grabbing prey.

We go from the chest to a long abdomen, which resembles a long stick of a round section. The abdomen is divided into ten segments. On the sides of each segment are the respiratory holes - the sparks. There are also reproduction organs. The entire color palette was used for the painting of dragonflies. The body can be black, red, yellow - whatever! A real combination of any colors, but not more than three.

There are species with colored spots and stripes.

The wings are usually transparent, but they are with colored shades - blue, red, greenish. In any case, the dragonfly seems to be a real artistic masterpiece. The dimensions of dragonflies can fluctuate wide. The body length of the most tiny does not exceed 15 millimeters when wingspan is wings. The largest grow to millimeters and have a wingspan millimeter. These are real giants in the kingdom of dragonflies.

As a rule, they live in South America. From eggs to imago, mating in dragonflies occurs directly in flight. The process can last from seconds to three hours. The female lays eggs under water. To do this, she has to dive to a depth of one meter! Eggs are attached to underwater plants or coastal silt. If a chicken is immediately hatched from the chicken egg, then the dragonfly passes three life cycles.

The first is the stage of the egg. In different types, it can be round or oval, and also have different colors. One dragonfly can at once postpone half a thousand eggs! There are those who in a couple of months lay up to 3 thousand eggs. The reason for the wastefulness is easily explained - a quarter of eggs dies from extreme temperatures, poor ecology, predators and parasites.

Egg ripening is significantly different in different types and can fluctuate from several weeks to nine months. A larva appears from the egg, which vaguely resembles an adult individual, but without wings. Larvae live in water, breathe gills. They easily tolerate freezing and drying of the reservoir, literally reviving when water appears. The appearance can differ greatly in different types of dragonflies.

The most amazing thing is that the larvae have perfectly developed all the senses - vision, smell, touch. The stage of the larva can last from three months to six years. The end of the cycle is the Imago - an adult stage of the development of the dragonfly, when it has wings. But first, larvae should get used to the ground lifestyle, because they are creatures from the underwater world.

With great caution, the larvae rise to the surface of the water along the stems of aquatic plants and learn to breathe air. In the early days, the adaptation process lasts several hours. Then the larvae remain on the surface for several days.And only fully accustomed to another world, they get ashore, are freed from the shell and turn into a dragonfly! From this moment, a completely different life begins.

Planet Dragonfly World Dragonfly is unusually diverse. According to zoologists, there are more types of these flying insects, and every year this figure increases by a couple of dozen species. Dragonflies are found on almost all continents. The exception is only Antarctica. Scientists have found that the northern border of the habitat is a conditional line, where the air temperature is stable for three months.

Among the species there are real record holders that live in vast territories, including a variety of natural zones. For example, the imperator patroller can be seen both in South Africa and near the polar circle in Europe. But the winner in this nomination is not a imperator, but a red-haired wanderer, which is found everywhere except Antarctica! In the Himalayas she was seen at a height of meters, where life is virtually impossible.

This is the only type of dragonfly that populated the island of Easter. But the most amazing thing is that the Red -haired tramp was first inhabited by the Bikini Atoll after the atomic bomb was blown up on the island! It seems that this type of dragonfly could take root on Mars. For dragonflies, the main thing is the presence of water. Without it, the life of the larva is impossible.

Ponds, lakes, rivers, streams, ditches - all this can be a welcome home. The paradox is that dragonflies are not at all in Lake Baikal. There are types of larvae that can live only in running water, others prefer stagnant, swamp, the third give mineralized water so that there are more alkalis in it. There are those who are used to basking in thermal springs so that the water temperature is at least 50 degrees.

There are dragonflies that develop in rain water, accumulating in large leaves of tropical plants. The primacy of the variety of species is held by the Indo-Malay zone, which includes the territory of South and Southeast Asia. Next is Neotropic - South and Central America. The three leaders completes Afrotropic and Australia. The Arctic, on the contrary, is characterized by the minimum number of dragonflies.

It is too cold for them there. Life on hunting for most of his life is a dragonfly in flight in search of food. Insects are divided into two groups - with two pairs of the same wings and with two pairs of different wings. They are called equally winged and diverse. The former are poor pilots. They flutter slowly and try not to fly away far from the reservoir.
