What does it mean when bees "bee-fan"?

The term "bee-fan" refers to the behavior of bees collectively vibrating their wings in unison to create airflow within the hive. This action is essential for regulating the internal temperature, especially during hot days when the hive can become overheated. By fanning, the bees increase air circulation and help to cool the hive, thereby maintaining a suitable environment for the queen, brood, and stored food.

This behavior is particularly crucial during the heat of summer or in warmer climates, as it helps to stabilize the temperature at which brood development can occur and protects the hive's stored honey and pollen from heat damage. In contrast, while swarming preparation, communication, and cleaning are important bees' activities, they do not specifically involve the behavior of fanning, which is exclusively linked to temperature regulation.
