A honey bee colony’s ability to survive the winter depends on their food stores of honey. Once the colony begins to run out of honey, the worker bees force the useless drones from the hive, to maintain the food store.

As temperatures drop, the honey bee workers form a cluster around the queen and brood, keeping them warm. Bees on the inside of the cluster can feed on the stored honey. If surrounding temperatures rise, the bees on the outside of the group separate a bit, to allow more air flow. As temperatures fall, the cluster tightens, and the outer bees pull together.

As it gets colder, the worker bees actively ...
