The queen is the most important bee in the colony and is very different from both other types found in a hive. The queen's job is to breed with the drones and lay eggs. It may not be much of a job, but it is through her that the colony can continue year after year. The queen lays enough eggs to keep the hive in workers for the spring and summer and also knows when to begin laying eggs again in the winter. There is only one queen per colony of bees and when she dies the worker bees will choose new worker larvae to replace her. In order for the worker larva to develop into a queen, they must be fed a special substance called 'royal jelly' which contains mandibular gland secretions from young worker bees and more honey than worker bees get. The queen also has control over the hive in that she secretes pheromones to regulate the behaviour of all the bees in the hive.
The lifespan of the bees varies greatly between different types: the queen can live anywhere from two to seven years; workers live for 30-50 days, whereas drones live for around 55 days.
