How many eyes does a dragonfly have, what kind of eyes do dragonflies look like?

Dragonflies have 1 pair of compound eyes, each of which is composed of many small eyes, and the compound eyes are composed of about 28,000 small eyes.

Dragonflies are the insects with the most eyes in the world. Dragonflies have large, bulging eyes that take up the majority of their heads, they have excellent eyesight, and they can look up, down, forward, and backward without having to turn their heads.

Each eye is a small camera, and the surrounding objects are constantly ingested to form images. It can see things up to 6 meters. The whole compound eye is spherical, and its curved surface can take care of all directions, and the dragonfly's large head can rotate freely, so that the dragonfly's field of vision is very wide.

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 the speed of the target object can be determined after processing. This makes them masters of insect catchers in the insect world. Its chewing mouthparts are well-developed and powerful.

Dragonfly has 1 pair of compound eyes, but each compound eye is composed of many small eyes, generally a compound eye has more than 28,000 small eyes, dragonfly is the insect with the most eyes in the world, dragonfly eyes are large and bulging, occupy the vast majority of the head. Dragonflies are carnivorous insects, they prey on flies, mosquitoes, leafhoppers, midges and small butterfly moths and other agricultural, forestry and animal husbandry pests, is beneficial to humans a class of important natural enemy insects, and "dragonflies point to water" is the biological characteristics of dragonflies to lay eggs in water.

<> dragonfly's big eyes are made up of 10,000 to 28,000 small eyes. This is the most common in insect festivals, so it has particularly good eyesight among insects, and can see clearly five or six meters away. Dragonfly eyes appear round and large, taking up almost 2 3 of the area of its head.

Moreover, the dragonfly eye has a very interesting function: the upper part of the whole eye is responsible for seeing distant objects, and the lower half is responsible for seeing near objects, and this division of labor makes it suitable for predation, both near and far, timely and accurate. But if you quickly shake the upper part of the dragonfly's eyes, it will be dizzying and easy to catch, which is also the weakness of the dragonfly's eyes.

Dragonfly eyes are particularly sensitive to moving objects and can determine the direction and speed of prey based on the direction and time it takes for small flying insects to move from one eye to another. When an object suddenly appears, it takes seconds for the human eye to see the outline, while it takes less than seconds for a dragonfly to see clearly. So, it's easy for dragonflies to catch their prey.

Dragonflies come in a variety of colors, including red, yellow, black, grass green, and flower colors. The dragonfly is a flying insect that can be compared to the speed of the women's 100-meter sprint world champion and the speed of a running train.

The dragonfly's long wings, which support its body smoothly, fly freely, and even the wind will not make it shake. Above the leading edge of each wing, there is a beautiful thickened section of skin, biologically called a wing nevus or wing eye, which plays a role in smooth flight.

The flight speed is 50 70 kilometers per hour. Its long-range flight is even more amazing. There is a dragonfly that travels from the east coast of England to France.

There is also a species of sea dragonfly that can fly to Japan from near the equator. Australian sea dragonflies can fly from the Australian mainland to 500 kilometers from the mainland to cruise in the sea, a round trip is 1,000 kilometers. Therefore, the ability of dragonflies to fly is very famous in the insect world.

According to this revelation, people add a counterweight to the two wings of the aircraft, so as to avoid the accident that the aircraft often fails to control and even breaks the wings due to violent vibration when flying at high speed.

The eyes of insects are unique, and almost every one of their eyes is made up of thousands of small hexagonal eyes arranged in close proximity. Each small eye has its own system, each with a refractive system and sensory cells, and all have vision, this peculiar eye is called "compound eye" in zoology.

The compound eyes of dragonflies are the largest and most in the insect kingdom, accounting for 2 3 of the total area of the head, up to about 10,000 birds, 10 times that of ordinary insects, and the structure is very peculiar: the upper part looks at the distance, and the lower part looks close. In this way, when it catches small insects in the air, it can be handy, and it will never miss.

Summary. Hello dear, dragonflies have 10,000 eyes, dragonflies have 28,000 small eyes in each compound eye, and there are 10,000 glasses in two compound eyes. The dragonfly in nature is a compound eye, the compound eye of the dragonfly is the largest and most in the insect world, accounting for 2 3 of the entire head, and the two large compound eyes of the dragonfly are composed of 28,000 small eyes, so there are 10,000 dragonfly eyes, which is 10 times that of ordinary insects.

It is the animal with the most eyes in the world, and I hope it can help you <>
