Honeybees are a highly fascinating, remarkably organized society. Typically, they live in colonies which consist of a queen, hundreds of drones and 20,000 to 80,000 female worker bees. A bee colony is known as a super-organism as no single bee can survive on its own. There is division of labor and every bee must carry out their own duties and co-operate with one another for survival. The following lists the roles and responsibilities of bees in a hive.
The queen is the only fertile female in the colony. It is the only member that is able to lay fertilized eggs. The queen bee continually emits pheromones, a bee perfume that only the bees in the hive can smell. These pheromones keep the female workers sterile and also act as a signal to assure all the bees in the colony that the queen is alive and all is well in the hive. It is believed that this unique scent provides the colony a sense of identity and personality. The queen mates early in life, stores up millions of sperm within her body, and fertilizes her eggs as and when needed. She is capable of producing up to 2,000 eggs within a single day. To produce drones, she lays unfertilized eggs. A queen bee lives for 3- 5 years. However, when it falters in her egg-laying performance, the hive will start looking for a replacement and feed royal jelly to a developing larva.
Worker bees constitute the largest population in the colony and are all females. They are unable to produce fertilized eggs, however if there is no queen, they sometimes lay unfertilized eggs, which become male drones. Each worker bee, guided by a biological clock, assumes different responsibilities and performs specific job duties as she reaches a certain age. Below are the different jobs and roles of the worker bees.
When they are about fourteen days old, the worker bees leave the nest at sunrise as foragers and visit the flowers four to five-kilometer radius from the hive in search of nectar, water, pollen and propolis. They can make about ten trips a day, each one lasting about an hour and return to their hive at sunset. At this final phase of life, at the age of 6 - 8 weeks, most worker bees will die in the field. During the winter, bees stop flying, hibernate in their hives and live on stored honey from fall to the next spring.
When the worker bees are a little older, they become in charge of removing dead bees and disposal of the corpses to a place as far from the hive as possible. Diseased or dead broods are also quickly removed by the undertakers before becoming a health threat to the colony.
Worker bees that are about 12 days old are mature enough to begin secreting and producing beeswax , the material for the construction of comb. The wax flakes they produce help with the building of new wax comb and in the capping of ripened honey and cells containing developing pupae. The bee must consume large amounts of food (honey and nectar) to produce these wax flakes. In 1999, Thomas Hales produced a 19-page mathematical proof that of all the possible structures such as rectangles, squares or triangles, honeycombs use the least amount of wax and are the most efficient and practical structures in nature . As Charles Darwin put it, the honeycomb is a masterpiece of engineering and is "absolutely perfect in economizing labor and wax."
Guarding the hive is the last task of a worker bee before venturing out to the fields. The guards inspect every bee that returns to the hive for a familiar scent. Only members of the hive are allowed to enter. Bees from other hives are occasionally allowed in when they bribe the guards with nectar. These "foreigners" steal some honey and pollen and leave. The guard bee also looks out for any crack through which a robber bee or intruder might enter the hive. These worker bees also defend their colony against other insects. When their stingers are used to attack the intruders, they tear their abdomen and die as a result. They also emit an alarm pheromone from a gland near their stingers to alert other bees on any impending danger.
