Why do bees fan their wings inside the hive?

Bees fan their wings inside the hive primarily to help cool the hive. This behavior becomes essential during hot weather, as it helps regulate the internal temperature of the hive. When bees fan their wings, they create airflow, which promotes evaporative cooling. This process lowers the temperature within the hive, ensuring the colony remains comfortable and the brood develops properly.

In addition to cooling, fanning also plays a role in drying nectar as it helps with moisture evaporation, but the main function in this context is temperature regulation. The ability to maintain a stable environment is crucial for the health of the hive and the productivity of the colony.
