Question: Do bees hibernate?

Roberto answered on 11 Nov 2018:

Well, t really depends on the species of the bees you are talking about. Bumblebees and solitary bees they hibernate as a single queen bee. In this case, all the bee colony die out before winter and the fertile queen bee goes into a sheltered place (ground, rocks, walls) and hibernates to survive the winter.
Honeybee, instead, does very differently. The colony does not die before the winter but increase the number of bees just to provide enough individuals to survive the cold winter. So, during the winter they form a very tidy cluster inside their nest to keep the place and themselves warm enough (like the penguins do during the winter). They are not hibernated, only very slow because of the cold, and if a bee abandons the cluster in a very cold day, she will die of cold. They can only fly during the winter during the warmest hours of the day only if the temperature is above 11 degrees.
