Why do bees only dance eight characters?

Tell your partner where the honey source is. . . . . . Bees rely on the sun to tell their directions. During the day, the direction of bee dance changes with time. Bees are located at three points: the hive, the honey collecting ground and the sun. The hive is the vertex of a triangle, and the vertex angle is determined by two lines: one is from the hive to the sun, and the other is a straight line from the hive to the honey gathering place. The angle between these two lines is called "sun angle", which is the "steering wheel" of bees. Bees fly half a small circle to the left and half a small circle to the right. The flight path is like an "8". But sometimes bees fly from top to bottom, and sometimes from bottom to top. The angle between the flying straight line and the vertical line on the ground is equal to the angle of the sun. It is from this angle that bees decide the location and direction of honey collection.

If bees fly straight with their heads up when dancing the figure-eight dance, then the angle of the sun is zero, which means: "flying towards the sun is the direction of collecting honey."

If bees fly head-down to the ground in the "8" dance, then the angle of the sun is 180, that is, "the place where they fly away from the sun is the place where honey is collected."

If the left included angle between the flying straight line and the vertical line on the ground is 15 when the bees dance the figure of eight, it means: "Flying 60 to the left sun angle is the place to collect honey."

Interestingly, bees in different places have different "dance languages". Bees in Austria can dance the eight-character dance, while bees in Italy can also dance the round dance and the curved sickle dance.

If the weather is bad, the clouds are overcast, there is no sun, and there is no polarized light in the air, bees will lose their ability to tell the direction.
