Why do bees go out after dark in such cold weather?

Cold weather and low temperature in the hive are not good for bees, because bees are warm animals, and their body temperature changes with the temperature of the surrounding environment. The clever little bee came up with a special way to resist the cold. When the temperature in the hive is as low as 65438 03℃, they are close to each other in the hive and form spherical clusters. The lower the temperature, the closer the colony is, which reduces the surface area and increases the density of bee colony to prevent excessive cooling. According to the measurement, in the coldest time, the temperature in the bee ball can still be maintained at around 24℃. At the same time, they also use more honey and exercise to generate heat to raise the temperature in the hive. In cold weather, the surface temperature of the bee ball is lower than the center of the ball. At this time, the bees on the surface of the bee ball drill to the center of the ball, while the bees in the center of the ball move outward. They took care of each other, changed places repeatedly and spent the cold winter. How do they eat honey stored in beehives during wintering and balling? Smart bees have their own tricks. They don't need to break up the spheres and climb out to eat separately, but pass them on to each other to get food. This can keep the temperature in the ball constant or change little, which is conducive to safe wintering.
