The orientation of bees in flight mainly uses the signs on the ground, the position of the sun and polarized light. The identification of nests near the nest door mainly depends on the color, mark and smell of the nest door. When bees are far away from the hive, the general direction of the hive is mainly determined by the position of the sun and the polarized light emitted by the sun on cloudy days, while the location of their hive is mainly found by closely combined and continuous ground signs, such as Woods, highways, rivers and so on. The use of ground markers is the result of bee learning and memory, which is the fundamental reason why new bees are easy to get lost in their nests. When bees fly near the hive, they will use their own identification marks and different colors around the hive to fly to the door of the hive. Use the different smells of bees to find your home accurately.
