What is so special about the eyes of bees, and why are they called thousand eyes ?

Everyone knows that pilots wear special black glasses before they take to the skies. Not only is it cool, but it also has a lot of features. And we bees also have a pair of sunglasses.

But this pair of sunglasses is innate. This is also very powerful for the eyes of bees, but unfortunately such powerful eyes are short-sighted. What the hell is going on?

Why do bees have black eyes? Bees fly at high speed for a long time, so they have a pair of eyes with a deceleration function, just like the glass windows on the Chinese Harmony train, or the glass windows on airplanes, which are made of special glass materials. The main effect is to slow down the amount of information that people receive from external objects when driving at high speeds, so that we will not get dizzy when we look out at high speeds.

The same goes for bees. His eyes have a good deceleration function and can move freely in nature without fainting. The faster you move, the clearer you can see, and the farther you can see, like a pair of "clairvoyance". But this deceleration function is a bit difficult when he is slow, like a person's myopia.

All the same, a little blurry. That's why when we stand still, bees always turn around and don't know what they're doing. In fact, they can't see us clearly because they're short-sighted.

Once you run, he will chase you. The reason why bees have completely black eyes is that bees have to face harsh sunlight when flying in the air, and long-term exposure to strong light can cause eye burns and blindness, so they evolved a pair of all-black eyes, which are as cool as wearing sunglasses.

The compound eyes of bees are not exactly the same. It is known that the compound eyes of bees grow on the sides of the head, but among the three species of bees, the male compound eyes are larger and connected, and the worker bee.

and queen bee compound eyes are smaller and separated. A bee's compound eye can't rotate like our eyes, but thousands of tiny eyes in a bee's compound eye can pass in different directions, so we don't think bees can't see behind them. It can be said that the compound eyes of bees cannot be rotated, but the field of vision is not small.

So, how do bees use these little eyes to get the job done? In fact, the compound eyes of bees are mainly used to observe distant objects, and when collecting honey, they can judge the location of flowers, the color and shape of flowers.

In a previous article, the bee tribe once said that bees build nests, partly during the day, but from above, compound eyes can't complete their work at night, and it seems that bees should also have a kind of eye, which is specially used to cope with night work. Not bad! Bees also have a third type of eye, which is the monocular that we often hear about.

Bees have three eyes, each of which is independent. It is located in the center of the bee's head and is distributed between the two compound eyes, forming a triangle.

Here, many friends may have guessed the effect of bee monoclenity, not bad! That's the night vision feature. The monocular vision of bees is not as good as that of the compound eye, but the vision is weaker, but there is one function that is stronger than the compound eye, and that is photosensitivity.

The bee's single eye can clearly perceive the intensity of light, so it is useful when observing objects in close proximity. For example, bees rely on one eye to complete their work at night, and at the same time, the single eye of bees can assist compound eyes.

Mainly because the eyes of bees can focus light, and they can play a very key role in many things.

Because the eyes of bees are compound eyes, when looking at things, it is like the feeling of having many screens put together, so it has such a title.

As you can see from the high-speed display, there are many small eyes on the bee's eyes that are refracted by thousands of eyes, so it will have the title of a thousand eyes.

This is because the bee eye has a very special structure, and it can see far away in terms of vision, and can see things from a long distance.

It is because the eyes of bees can observe relatively distant places in a short distance, and in this case, they can also know some surrounding dangers in time, so it has such a name.

Bees have a pair of compound eyes and three single eyes. The compound eyes are on both sides of the upper part of the head, and the single eye is in the middle of the top of the head, arranged in a triangular shape. Outwardly observed, worker bees.

There are 5 eyes, but in fact, each compound eye is made up of 4000-5000 small eyes.

A trace amount of chemical information released by bee glands is called pheromones.

Also called exohormones.

Transmission by air or contact between individuals is a kind of "language" that can be understood by the receiving individual, acting on behavioral or physiological responses.

Mainly dances, the most typical being the round dance and the tail swing dance. The dancer is the scout bee of the gathering bees, and the stage is the nest spleen in the nest that is perpendicular to the ground. The dance of the scout bee is selected according to the direction and distance of the nectar source detected.

If the scout bee finds the nectar within 100 meters of the hive, it dances like this: when the scout bee returns to the hive with the nectar it collects there, it first stays quietly on the hive for a while, then slowly spits out the nectar and holds it to its mouth, where its companions suck it out with their beaks.

Bees have a pair of compound eyes and three single eyes.

A bee's compound eye is not simple, consisting of thousands of small eyes. In fact, the compound eyes of bees are not exactly the same. The compound eyes of the bee grow on both sides of the head, but among the three types of bees, the compound eyes of the male peak are larger and connected, while the compound eyes of the worker bee and the queen bee are smaller and separate.

The compound eyes of bees are not like human eyes that can be turned, but the thousands of small eyes in the compound eyes of bees can be used in different directions. Compound eyes are mainly used for long-distance objects, and can judge the position of the flower and the color and shape of the flower when collecting honey.

The bee has three monoculars, each of which is independent and sits on the ** of the bee's head, distributed in the middle of the two compound eyes, forming a triangular shape. The role of the monocular is the night vision function.

The single eye of the bee can clearly feel the intensity of the light, so the single eye comes in handy when the object is close to the eye, for example, the work of the bee at night depends on the single eye to complete, and the single eye of the bee can also assist the work of the compound eye.

In addition to a pair of compound eyes, bees have three single eyes, which form a triangular arrangement with the two compound eyes to sense changes in luminosity and the direction of the light source, forming a rough image. A bee's eye is made up of about 5,000 small eyes, each of which has a set of light-collecting and light-sensing systems. The light collection system can form an image, and only the light parallel to the axis of the small eye can reach the visual column, that is to say, each visual column can only accept one light point of the object, and many felt light points form a "mosaic image", just as many light points with different light and darkness constitute the image on the TV phosphor screen.

The higher the number of eyes, the smaller the area of the eyes, the denser the light spots, and the clearer the image.

A bee's eye is called a visual apparatus: it is made up of 1 pair of compound eyes and 3 single eyes. The compound eye is made up of a number of sensory units (microphthalmia). Each eye in the compound eye is composed of 8 photoreceptor cells arranged in a radial pattern.

Worker bees have about 5,000 small eyes per compound eye, queen bees have about 4,000 small eyes, and drones have about 8,000 small eyes.

Fortunately, the institutional reform of the same person clothes just now.

2 compound eyes, 3 single eyes, a total of 5.
