At what temperature do honey bees cluster to maintain hive warmth in winter?

Honey bees cluster to maintain hive warmth during winter at approximately 93°F (34°C). This temperature is crucial for their survival as it allows the bees to keep the brood and queen warm while the outside conditions are cold. In winter, bees gather in a tight cluster, forming a spherical shape, and vibrate their bodies to generate heat. This clustering behavior enables them to create a microenvironment within the hive that stays at this optimal temperature.

Maintaining this temperature is vital for the bees' metabolism and overall hive health. If the temperature drops significantly below this level, it can jeopardize the survival of the colony. Therefore, the choice of approximately 93°F reflects the physiological needs of the bees in cold conditions, highlighting their communal efforts to ensure the hive remains warm and functional during winter months.
