They remain absolutely motionless and the liquid in their body slows slowly and carefully. Therefore, it does not start the crystallization process that promotes freezing. However, it you were to touch or move a supercooled insect, it might instantly freeze solid. Other insects synthesize and concentrate an antifreeze called glycerol, which lowers the freezing point of water. Another method some insects have developed as a defense against the cold is to produce heat in the abdomen.
Honeybees act together to generate heat.
In the core of the colony, the bees are producing heat and rotating with the bees on the edge of the core. It is fascinating how insects have adapted to surviving winter conditions. To plants, winter is a time of drought. The leaf is the center of food production. With the lower temperatures of falling winter, the food manufacturing process stops or becomes less efficient.
