Bee reproduction is a highly organized, communal process within a beehive. It involves a coordinated effort among various hive members, ensuring the colony’s continuation and prosperity by transforming tiny eggs into adult bees that contribute to the collective well-being.
The Royal Couple
Reproduction in a beehive centers on the queen bee and male drones. The queen is the colony’s sole fertile female, responsible for laying all the eggs that will become the next generation of bees. She mates early in her life during several nuptial flights, often seeking out specific “drone congregation areas” where thousands of male bees gather.
During these flights, the queen mates with multiple drones, typically between 10 and 20, in mid-air. After each mating, the drone’s reproductive organ detaches, and the male bee dies. The queen stores millions of sperm in a specialized internal organ called the spermatheca, which can sustain her egg-laying for several years. This stored sperm allows her to control the fertilization of each egg she lays, determining the offspring’s role in the colony.
The Bee Life Cycle
Honey bees undergo complete metamorphosis, involving four distinct developmental stages: egg, larva, pupa, and adult. The entire transformation from a newly laid egg to an emerging adult bee takes a varying number of days depending on the type of bee. This journey begins when the queen lays a single, tiny egg into a hexagonal beeswax cell.
After about three days, the egg hatches into a larva. This larval stage involves rapid growth, as the larva consumes large quantities of food provided by worker bees. Once the larva has grown sufficiently, worker bees cap the cell with wax, and the larva becomes a pupa.
Within the sealed cell, the pupa transforms into an adult bee. The duration of this pupal stage varies: queen pupae develop in about 7.5 days, worker pupae in approximately 12 days, and drone pupae in around 14.5 days. Finally, the adult bee emerges from the capped cell to begin its role within the hive. The total time from egg to adult is about 16 days for a queen, 21 days for a worker, and 24 days for a drone.
Different Paths
The fate of a developing bee—whether it becomes a queen, a worker, or a drone—is determined by both egg fertilization and the type of food it receives during its larval stage. Fertilized eggs develop into female bees. These female larvae can then become either sterile worker bees or fertile queen bees.
Unfertilized eggs develop into male bees known as drones. Drones are haploid, possessing one set of chromosomes from the queen. Their genetic origin determines their sex and role: drones exist primarily to mate with a queen.
The diet provided to female larvae is the deciding factor in whether they develop into a worker or a queen. All bee larvae initially receive royal jelly, a nutrient-rich substance secreted by worker bees. However, a larva destined to become a queen is fed royal jelly exclusively throughout its larval development, while worker larvae are switched to a diet of “bee bread” (a mixture of pollen and honey) after the first few days. This specialized royal jelly diet triggers a queen’s full reproductive capabilities and larger size.
Nursery Duty
Once the queen lays her eggs, the responsibility for raising the young falls to the worker bees, specifically young “nurse bees.” These nurse bees produce food for the developing larvae. They feed the newly hatched larvae royal jelly initially.
For those larvae developing into worker bees and drones, the diet shifts to bee bread, a mixture of pollen and honey. Nurse bees meticulously feed each larva. Beyond feeding, nurse bees also maintain optimal conditions within the brood cells, ensuring stable temperature and humidity. Once a larva is ready to pupate, the nurse bees cap the cell with a layer of wax, sealing it for pupation.
