Ever wonder how bees stay warm in the winter? It’s kinda cool:
In the winter, honeybees cluster together in a ball roughly the size of a basketball. By flexing their wing muscles (the same muscles they use to fly), they are able to generate warmth and hold the cluster at about 85-90 degrees. The bees take turns shifting from the inside to the outside of the cluster so that everyone can stay warm. The queen is always kept at the center of the cluster.
