Queen bee, worker bee and drone

Queens (perfect females)

  • The queen honeybee is the product of a fertilized egg, as are all females in the hive, however, the queen receives a special diet throughout larval Queen Bee photolife. That diet consists of royal jelly for the first 3 days and a modified jelly thereafter, and it takes 16 days to produce a queen from an egg. The queen bee is the biggest bee in the hive, mostly due to her elongated abdomen (for egg laying). She is the sole source of replacement bees for the many that die daily from a variety of causes (old age, predation and disease). And how many eggs the queen lays varies dependent on her age, health, and available clean and empty cells within the hive. She mates with a variety of drones during her maiden flights (mating does not occur within the hive), and can store enough sperm in her spermatheca1 to last her lifetime. Normally there is one queen in a hive but there can be exceptions and a queen may live 2 or more years.

Worker bees (imperfect females)

  • Worker bees are all females. They spend the first few weeks of their lives tending brood2 then shift jobs to foraging for food. It takes 21 days for an egg to develop into a worker bee and she can live, during foraging time 6 to 8 weeks but can overwinter in the hive. Worker bees are fed a larval diet which is deficient in some ways (from that given to the queen larva), and results in the bees sex organs not being fully developed. There are times though some worker bees may develop functioning ovaries and layWorker Honeybee unfertilized eggs (parthenogenesis) which normally will result in drone bees (this is a telltale sign of a queenless hive). Additionally, there is evidence from studies done with Apis mellifera capensis (the Cape honeybee) that a worker bee can/may become a pseudo queen and produce female offspring from diploid eggs also through a form of parthenogenesis (without mating) called Thelytoky. For additional information go here (about bees) or here (higher animals).

Drones

  • Drones are the male bees and they have no father (being the product of an unfertilized egg). They are very specialized in that they are defenseless (no stinger), do not forage (early in life are fed by workers), come equipped with very large eyes and antennae with specialized receptors enabling them to locate a queen on her maiden flight. Drone photoTheir sole purpose is to impregnate a maiden queen and if successful their reward is death (upon uncoupling they leave behind part of their anatomy which causes their demise). In areas with a prolonged winter they are evicted from the hive as the weather gets colder and they often die of predation. A drone is produced from the egg after 24 days and can live for approximately eight weeks.

Understanding the Role of the Drone Bee in a Hive

 

The drone is the only male bee in the colony. Drones make up a relatively small percentage of the hive’s total population. At the peak of the season, their numbers may be in the hundreds. You rarely find more than a thousand.

Procreation is the drone’s primary purpose in life. Despite their high maintenance (they must be fed and cared for by the worker bees), drones are tolerated and allowed to remain in the hive because they may be needed to mate with a new virgin queen (when the old queen dies or needs to be superseded).

Bee mating occurs outside of the hive in mid-flight, 200 to 300 feet in the air. This location is known as the “drone Mating Area”, and it can be a mile or more away from the hive. The drone’s big eyes come in handy for spotting virgin queens taking their nuptial flights.

The few drones that do get a chance to mate are in for a sobering surprise. They die after mating! That’s because their sex organ is barbed (like the worker bee’s stinger). An organ inside the queen called the “spermatheca” is the receptacle for the sperm. The queen will mate with several drones during her nuptial flight. After mating with the queen, the drone’s most personal apparatus and a significant part of its internal anatomy is torn away, and it falls to its death.

Once the weather gets cooler and the mating season comes to a close, the workers will not tolerate having drones around. After all, those fellows have big appetites and would consume a tremendous amount of food during the perilous winter months.

So in cooler climates at the end of the nectar-producing season, you will see the worker bees systematically expelling the drones from the hive. They are literally tossed out the door. For those beekeepers who live in areas that experience cold winters, this is your signal that the beekeeping season is over for the year.

Depending upon where you live, the calendar of events for you and your bees varies depending upon temperature ranges and the time of year.
