A bee is an insect with complex eyesight. It has five eyes: two multi-faceted large eyes and three simple eyes, which are located on the back of the insect's head.

Instructions

Step 1

The compound eye is about 6000 small independent ocelli (facets). Bees need these eyes in order to identify places where they can collect nectar, to navigate outside the nest. Bees need simple eyes for orientation inside the hive. Drones have up to 8000 facets, and their eyes are even more complex, since the drones must track the uterus during mating flight.

Step 2

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

Step 3

Experiments with bees were carried out by scientists in various conditions, as a result, it was found that the bee's eye perceives shorter light waves than the human eye. Bees not only see in the red to violet range, they also see ultraviolet waves.

Step 4

Based on this, we can draw conclusions - bees see more shades than people, and flowers that seem the same to us are distinguished by insects. In any case, flowers that are white for humans, for bees, have different shades. However, scientists have found that bees do not distinguish between red, and it could be assumed that shades of red seem black to them. But everything is not so simple, red color, if you look at it more closely, has some part of blue undertones, and blue bees see well. It turns out that if a person could see flowers as bees see them, they would seem much more beautiful to him. That is, the poppy flower for the bee is not red, but "ultraviolet".

Step 5

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

Step 6

However, the bee can only distinguish large objects. Despite the fact that she herself is tiny, when compared with a person, her eye is not able to perceive small details. A person sees objects 30 times smaller than those that a bee can see.
