Apart from being significantly larger than workers, the roles that queens perform is very different from that of other members of the colony.
In a colony of 50,000 bees, there will be only 1 queen,
and perhaps around 300 drones (males) and the rest will be female worker
In an active colony of honey bees, then depending on age, workers perform a range of activities.
The role of worker honey bees includes:
The role of drones is to mate with honey bee queens from different hives.
Despite the difference between herself and the female workers, what may surprise many is that she is produced from eggs that are in every way identical to those eggs producing workers. The difference, however, is that larvae of potential queens are fed only a special substance called ‘royal jelly’.
About a week after a new queen emerges from her cell, she will take several flights in order to mate. She may mate with as many as 20 drones, all while in the air! (The drones, unfortunately, die after mating). However, when the honey bee queen returns to lay her eggs, she will only rarely leave the colony after that. Inside her, she will have enough sperm (which she stores in her sperm pouch – or spermatheca), so that she may continue to fertilise her eggs for the rest of her life.
When she returns to the colony from her nuptial flight, and now impregnated, the workers begin fussing over her. They feed her so that her abdomen swells, and lick her – a process which transfers a chemical (pheromone), used to regulate the colony.
Pheromones are produced by the drones and workers, as well as the queen, who produces a ‘queen pheromone’. The queen pheromone encourages workers to tend to her and the brood, whilst at the same time, inhibits the production of more queens.
So efficient is the pheromone for
communicating within the colony, that if the queen is removed from a
hive, within 15 minutes, all of the bees will know about it, and will
frantically begin the task of creating a replacement!
When colonies become very large so that workers cannot (due to the distance between themselves and the queen), detect the queen pheromone, then this encourages part of the colony to create a new queen.
A new colony will then be formed.
However, it is the ‘old queen’ that will leave to find a suitable new nest, rather than the new one!
This initiates 'bee swarming'. A clump of workers surrounding a queen honey bee might be seen resting temporarily on a tree branch or post whilst 'scout bees' are looking for a suitable place for a permanent nest. You can read more about this fascinating event by clicking on this link.
Honey bee queens live much longer than workers and drones. (You can learn more about this by reading about the honey bee life cycle).
If the queen performs well in the colony, she will probably live two or three years, but possibly as many as four or five. However, if she produces too few eggs, she may be replaced by a new queen. The new queen will be pampered with food and affection, whilst the old queen is left to waste away.
