How do bees see
The bee is an insect with a complex vision. She has five eyes: two multi-large large eyes and three simple eyes that are on the occipital part of the insect's head.

A complex eye is about 6000 independentsmall eyes (facets). These eyes are needed by the bees in order to identify the places where it is possible to collect nectar, to navigate outside the nest. Simple eyes for bees are needed for orientation inside the hive. Drones have up to 8000 facets, their eyes are even more difficult, since drones must track the uterus during the mating flight.

Faceted vision is also called mosaic, since the final image that the bee receives is composed of individual images obtained by each facet.

Experiments with bees were conducted by scientists in variousconditions, it was eventually found that the eye of the bee perceives shorter light waves than the human eye. Bees are seen not only in the range from red to violet, they see and ultraviolet waves.

Proceeding from this, it is possible to draw conclusions - beessee more shades than people, and flowers that seem identical to us, insects distinguish. In any case, flowers, white for man, for bees have different shades. However, scientists have established that red bees are not distinguishable, and it could be assumed that the shades of red appear to them black. But everything is not so simple, the red color, if you look closely at it, has some of the blue halftones, and the blue bees see well. It turns out that if a person could see flowers as they are seen by bees, they would seem to him much prettier. That is, the poppy flower for the bee is not red, but "ultraviolet".

Bees distinguish up to 200 flashes of light per second, inwhile man - only 20. This makes it possible for bees to communicate with each other, they actively move into the hive, quickly move their paws and wings, while the person does not notice these movements, and the bees see them distinctly. This helps the bees to sit unmistakably even on a rocking flower, clearly defining the distance to it.

However, the bee distinguishes only large objects. Despite the fact that she herself is tiny, if compared with a man, her eye is not capable of perceiving small details. A person sees objects 30 times smaller than those that a bee can see.
