Bees per Hive with Queen

Bee Population per Hive (Single Queen)

A honey bee colony is a matriarchal superorganism built around one egg-laying queen. How many workers it carries at any moment tracks how much brood is being raised: N = laying_rate × worker_lifespan × survival. At the height of the season the queen lays 1,500–2,000 eggs per day, while adult workers only live 4–6 weeks in summer. An established colony usually runs 40,000–60,000 workers, anywhere from a few hundred to a few thousand drones, and a single queen.

The queen herself lives 2–3 years, sometimes as long as 5, and she is the colony’s only fertile female. She mates just once, taking 10–20 drones on a single mating flight and tucking their sperm away in her spermatheca. Workers nudge her laying rate up or down by how much royal jelly they feed her, and they build or tear down queen cups whenever supersedure or swarming is on the horizon.

Applications

Beekeepers size up the population to know when to add supers (the honey boxes that go on once foragers start crowding the brood chamber), to catch a colony that has gone queenless (eggs and capped brood drop off), and to judge whether a hive is healthy enough before signing pollination contracts. A frame of capped brood throws off roughly 6,000–8,000 new workers as it emerges.

FAQ

How do workers communicate forage location? They use the waggle dance, which Karl von Frisch worked out (Nobel Prize in Physiology or Medicine, 1973). The angle of the waggle against the vertical points to the direction of the food relative to the sun, and how long the waggle runs tells the others how far away it is.

What happens if the queen dies? The workers notice within hours, since the queen pheromone fades, and they raise emergency queens from young worker larvae fed nothing but royal jelly. A new mated queen is up and running in 21–28 days.

Why are drones present only seasonally? Drones do no foraging and no upkeep around the hive, so they get thrown out before winter to stretch the stores. The colony only rears them again in spring, when there are queens to mate with.
