Swarming is the process by which a new honey bee colony is formed when the queen bee leaves the colony with a large group of worker bees. In the prime swarm, about 60% of the worker bees leave the original hive location with the old queen. This swarm can contain thousands to tens of thousands of bees.
A honey bee colony can contain up to 60,000 bees at its peak. It takes a lot of bees to get all the work done. Nurse bees care for the young, while the queen's attendant workers bathe and feed her. Guard bees stand watch at the door.
