Why do bees know where nectar is?

The spectrum seen by bees is different from that seen by humans. They can't see red light (they may call what we call red light "yellow light"). However, they can see ultraviolet rays with shorter wavelengths and can accurately distinguish ultraviolet rays from various shades of white and gray. For them, ultraviolet light is a very bright color, sometimes called "bee purple". Just because bees can see ultraviolet rays and flowers can reflect ultraviolet rays in the sun, they can also attract bees.

Second, bees have "radar"

Bees' tentacles always swing two whiskers up and down from left to right, just like two antennas and radars, always receiving electric waves and tracking targets. This is because the antenna is an important sensory organ of bees, which has the functions of smell and touch. There are countless sensory organs on the antenna, which are connected with many nerve endings in the sensory fossa, and they are directly connected with the central nervous system. When stimulated by the outside world, the central nervous system can dominate insects to carry out various activities. The antenna of bee belongs to knee-shaped antenna, and its olfactory fossa is mainly distributed at the front end of antenna whip joint. With the help of tentacles, bees can smell the fragrance of various flowers and find nectar.

Conclusion: The detective bees in Bees used radar to find the honey source for the first time, and then told their companions through dance that finding the same honey source again was a comprehensive application of radar and bee purple. God's creation is always fair. It's interesting to throw red and make up for ultraviolet rays.
