How do honeybees keep the broodnest at a steady temperature?

Honeybees maintain a precise and steady temperature in the broodnest—typically around 93–97 °F (34–36 °C)—through sophisticated behavioral regulation.12

To achieve this, the colony employs several methods depending on environmental conditions:

• Heating: When the hive is too cool, worker bees generate heat by constantly contracting their muscles. This agitation, similar to human shivering, produces body heat that warms the broodnest. During colder periods or winter, bees also form a tight cluster to conserve heat, with the queen often positioned in the warmest core section.342
• Cooling: If the nest becomes overheated, bees regulate the temperature through air-conditioning. They collect water and distribute it within the hive, then use their wings to beat and circulate air, which facilitates cooling through evaporation.21

This ability to modulate the internal environment is essential for the development of the brood and the overall survival of the colony.31
