Honeybees choose their queen through a precise biological process driven by worker bees, royal jelly, pheromones, and specialized queen cells. When a hive needs a new queen because of aging, swarming, or sudden loss, workers select very young larvae and feed them exclusively on royal jelly, triggering queen development. The surviving virgin queen then defeats rivals, takes mating flights, and becomes the colony’s only fertile female, ensuring hive survival through collective intelligence.
