Generally speaking, activities start from April to May in spring. Each queen bee builds 1 nest and lays eggs in all corners of the hive at the same time, with 1 egg in each room for 7 days. Larvae adhere to the wall with caudate groove. The queen bee feeds on all kinds of soft worms, and the larval stage is 20 days. Mature larvae spin silk and feed them in a sealed way. In autumn, there are thousands or tens of thousands of bees in 1, and they breed quickly in July and August. When the fruit trees mature, worker bees feed on juice and pulp, and then return to their nests to feed their larvae. After the new bee breeds, the old queen dies, and after the new bee and the drone mate and fertilize, they leave the nest to find a wintering place to spend the winter.
Most worker bees and drones die, and only the fertilized queen bee overwinters in tree holes, walls or cracks in rocks.
