What is the temperature in a bee hive all year?

Answer 1

Most social insects, such as wasps and bumlebees die out at the onset of winter, and the queens will hibernate at very low body temperatures (just above freezing). During the colony cycle, however, the temperature of the brood can be much higher than the ambient temperature, more than 30oC. It only helps workers that need to be about 20oC to fly. If they cool down they are able to shiver to warm up to flight temperature.

More impressive is the honeybee, who's colonies live year round. They do not produce young in the winter, but huddle together for warmth. Even in the middle of winter, the temperature in the huddle will not drop below 30oC, and when the colony has brood, the brood temperature will not vary more than human body temperature: between 36 and 38 oC.
