Sometimes tiny convex disks marked with identification numbers ( Opalithplättchen) are used when a beekeeper has many queens born in the same year - a method that can also be used to keep multiple bees in the same hive under observation for research purposes. [15] Queen rearing [ edit ] If a queen suddenly dies, the workers will attempt to create an "emergency queen" by selecting several brood cells where a larva has just emerged which are then flooded with royal jelly. The worker bees then build larger queen cells over the normal-sized worker cells which protrude vertically from the face of the brood comb. Emergency queens are usually smaller and less prolific than normal queens. During the warm parts of the year, female "worker" bees leave the hive every day to collect nectar and pollen. While male bees serve no architectural or pollinating purpose, their primary function (if they are healthy enough) is to mate with a queen bee. If they are successful, they fall to the ground and die after copulation. Any fertilized egg has the potential to become a queen. Diet in the larval stage determines whether the bee will develop into a queen or a worker. Queens are fed only royal jelly, a protein-rich secretion from glands on the heads of young workers. Worker larvae are fed bee bread which is a mixture of nectar and pollen. All bee larvae are fed some royal jelly for the first few days after hatching but only queen larvae are fed the jelly exclusively. As a result of the difference in diet, the queen will develop into a sexually mature female, unlike the worker bees. [3] Seeley, Thomas D. (2009-06-30).

If the prime swarm has a virgin queen and an old queen, the old queen will usually be allowed to live. The old queen continues laying. Within a couple of weeks she will die a natural death and the former virgin, now mated, will take her place.
The queen bee's abdomen is longer than the worker bees surrounding her and also longer than a male bee's. Even so, in a hive of 60,000 to 80,000 honey bees, it is often difficult for beekeepers to find the queen with any speed; for this reason, many queens in non-feral colonies are marked with a light daub of paint on their thorax. [13] The paint usually does not harm the queen and makes her easier to find when necessary. As the young queen larva pupates with her head down, the workers cap the queen cell with beeswax. When ready to emerge, the virgin queen will chew a circular cut around the cap of her cell. Often the cap swings open when most of the cut is made, so as to appear like a hinged lid.

Queen cells start out as queen cups, which are larger than the cells of normal brood comb and are oriented vertically instead of horizontally. Worker bees will only further build up the queen cup once the queen has laid an egg in a queen cup. In general, the old queen starts laying eggs into queen cups when conditions are right for swarming or supersedure. Swarm cells hang from the bottom of a frame while supersedure queens or emergency queens are generally raised in cells built out from the face of a frame.

If she is unable to fly for several days because of bad weather and remains unmated, she will become a "drone layer." Drone-laying queens usually signal the death of the colony, because the workers have no fertilized (female) larvae from which to raise worker bees or a replacement queen. [9]
The term "queen bee" can be more generally applied to any dominant reproductive female in a colony of a eusocial bee species other than honey bees. However, as in the Brazilian stingless bee ( Schwarziana quadripunctata), a single nest may have multiple queens or even dwarf queens, ready to replace a dominant queen in case of a sudden death. [2] Development [ edit ] Older queen larvae in queen cell lying on top of wax comb A queen cup Queen larvae floating on royal jelly in opened queen cups laid on top of wax combVirgin queens appear to have little queen pheromone and often do not appear to be recognized as queens by the workers. A virgin queen in her first few hours after emergence can be placed into the entrance of any queenless hive or nuc and acceptance is usually very good, whereas a mated queen is usually recognized as a stranger and runs a high risk of being killed by the older workers. A special, rare case of reproduction is thelytoky: the reproduction of female workers or queens by laying worker bees by parthenogenesis. Thelytoky occurs in the Cape bee, Apis mellifera capensis, and has been found in other strains at very low frequency.

Queen rearing is the process by which beekeepers raise queen bees from young fertilized worker bee larvae. The most commonly used method is known as the Doolittle method. [16] In the Doolittle method, the beekeeper grafts larvae, which are 24 hours or less of age, into a bar of queen cell cups. The queen cell cups are placed inside of a cell-building colony. [17] A cell-building colony is a strong, well-fed, queenless colony that feeds the larva royal jelly and develops the larvae into queen bees. [18]
