Bee Knowledgeable Answers: The Rise of a Queen

There are always plenty of questions about the bees that are left behind in the hive, the other half of the colony. They cannot survive without a queen to lay eggs, so what happens?
Let’s find the answers to the questions that are raised about the birth and first month of life for a virgin queen honeybee.

1) How is a new queen made?
You should know the answer to this one. We covered it in April in Bee Knowledgeable: Swarming and in May’s Bee Knowledgeable: Royal Jelly.
When the colony becomes overpopulated and a natural swarm is necessary, the workers prepare for it. As part the colony gets ready to take off with the old queen, the workers start a few new queens developing. They do this by moving some eggs to queen cups and supply plenty of royal jelly. By the time the colony swarms and the old queen leaves, new queens are almost ready to hatch.

2) If there is more than one new queen, what happens?
(This one’s for you, Jordan)
There can only be one queen in the colony at a time. It is her pheromones that keep the colony happy. In our example of a swarm, there are several virgin queens about to hatch. Usually, the first queen that emerges will go around to the other queen’s cells and sting the un-hatched queens through their cell wall, effectively killing her rivals. If more than one queen hatches at the same time, they will fight to the death.
The pheromones of the victorious queen will now start to permeate the hive. Her scent will become stronger once the virgin queen has mated and then workers will take care of her. In three to four days after hatching she will leave the colony for her mating flight.

3) What happens on a mating flight?
Drones will leave the colony in the early afternoon to spend time in a “drone congregation” area. This is, as it sounds, one area where drones from nearby colonies will go and hang out. They wait for a chance to mate with a new queen.

Three to four days after emerging from her cell, a virgin queen will take off on a mating flight. We believe she uses her sense of smell to find a drone congregation area.  She will mate with 12-15 drones. If the weather permits, she might go everyday for several days. She will store the sperm from this mating flight to produce fertile eggs for the rest of her life. Having mated with several drones, she can ensure genetic diversity in the brood she produces.

The mating flight takes place in the air. The very large eyes of the drone bee serves to help him spot the queen and maneuver around her. If the mating is successful, the drone’s reproductive organ will be left inside the queen. Part of the drone’s abdomen will also be torn out. He will die soon after mating, having helped ensure the continuation of his species.
