At what temperature range does the clustering behavior of bees begin?

Clustering behavior in bees is a critical survival strategy, particularly in cooler temperatures. This behavior typically begins at temperatures between 54 to 57 degrees Fahrenheit. When the external environment cools down, bees will cluster together to maintain warmth within the hive. By vibrating their muscles, they generate heat, which helps to keep the queen and brood warm and protected during colder weather. Understanding this temperature range is essential for beekeepers, as it helps inform management practices during temperature fluctuations to ensure the health and survival of the colony.
