How do bees regulate the temperature within the hive?

Bees use a combination of fanning their wings and clustering to effectively regulate the temperature within the hive. When the hive becomes too warm, worker bees will fan their wings to create airflow, which helps to circulate air and evaporate excess moisture. This action cools the hive, much like a natural air conditioning system. Additionally, bees will cluster together to generate and maintain warmth when needed, particularly in colder temperatures.

This dual strategy of fanning and clustering allows bees to maintain a stable internal environment crucial for the health of the colony and the development of brood. In contrast, simply moving to cooler areas or using water to evaporate are limited methods and not the primary means by which bees maintain hive temperature. Sealing the entrance is typically a behavior employed during colder months to retain warmth but does not actively aid in cooling the hive. Therefore, the chosen method of fanning and clustering stands out as the most effective way for bees to manage their hive temperature.
