Unlike other bees, honeybees do not hibernate during cold weather. They make it through cold Northern winters by feeding on stored supplies and sharing their body heat, clustering together in dense packs. Honeybees are part of the family Apidae. Socialization is most advanced among honeybees. As new, young queens are about to emerge into an established hive, half of the colony leaves with the old queen and clusters on a nearby bush or tree while scout bees search for a new home. When the scouts appear to agree on a new location, the swarm departs. Meanwhile, at the old next, the first queen to emerge disposes of the other queens before they have a chance to emerge. Within a few days, the virgin queen will fly to where drones assemble and mate with between six and 12 drones.
