Bees are a kind of social insects, which live in groups with hives as storage places. Bee colony is an independent living unit, which can thrive. A swarm of bees usually consists of three individuals with different shapes and functions, namely a queen bee, tens of thousands of worker bees and thousands of drones. They live in the same hive. Individual division of labor is different, but interdependent. Just like organisms, they can resist the cold and heat of nature. Each colony has its own unique smell, and there are strict colony boundaries between colonies. In the natural state, worker bees have the characteristics of rejecting other groups of worker bees and queen bees, and each group of worker bees and queen bees belongs to its own nest. In addition to the natural alternation of the old and new queen bees, the queen bees are also incompatible with each other. Unmanned aerial vehicles (UAVs) have no strict bee colony boundaries and can freely enter and leave different bee colonies. When honey powder and feed are in short supply, they will also be expelled by worker bees in the bee colony.
The size of a swarm of bees depends on the number of worker bees. Different kinds of bees, different seasons, different queens, different sizes of bees. An excellent Italian queen bee can maintain the number of worker bees in the bee colony as high as more than 60 thousand in the prosperous season. When reproduction resumes, the number of worker bees in poor bees can be as few as several thousand. In the prosperous season, a good queen bee can only maintain the population potential of 30,000 ~ 40,000 bees.
