How much below zero will freeze bees to death

What is the suitable temperature for bees?

Generally speaking, a temperature between 15°C and 25°C is a suitable temperature for bees. Bees are not thermostatic animals. The climate has a great impact on bees. The severe cold in winter is quite detrimental to the survival of bees. Fortunately, bees have honeycombs to provide shelter from wind, rain and warmth. ; When the outside temperature is as low as 8℃, the muscles on the bee’s feet begin to freeze slowly. In this case, it can be regarded as a critical point of clumping; when the outside temperature is as low as 13℃, some older people Bees can leave the nest, but they can’t stay for too long, because if it takes too long, the wings of the bees will become stiff and unsuitable for flying; when the temperature is 14～15℃, the bees can fly normally in the outside world. The ability to fly will also be enhanced; when the temperature is higher than 28°C, its flight ability begins to decay; when the temperature exceeds 40°C, the bees almost stop flying and can go out to collect water at most.

So how much temperature will freeze bees to death?

If the outside temperature is below minus 5°C for a long time and the bees are not in the colony, they will soon be frozen to death. Of course, this temperature value is not absolute, because different bees species have different cold tolerances. , Such as the northeast black bee and the Changbai mountain bee are relatively hardy species. A single bee cannot leave the colony. The bees that leave the colony will soon be frozen to death without the protection of the colony’s strength, but if they stay in the hive, the bees will not be easily frozen to death. Because the beehive is a relatively confined space, its space is small, and it can shelter the bees from wind and rain. The bee colony "hugs and warms" in the beehive, and the bees will survive the severe winter smoothly under the power of the colony.
