Drones are fertile male honey bees, and they are vital for the survival of honey bee colonies. Their primary role is to mate with a receptive queen honey bee, in order to ensure future generations of honey bees, and indeed, expansion and creation of new colonies.
I've heard it said that drones don't do much because (say some):
The fact is:
Drones perform precisely the role that nature gave them, and as such, they are a vital part of the honey bee colony.
In addition, understanding of the broader role of the drone within the bee colony is increasing with further scientific research.
Below, you can read about the importance of honey bee drones.
10 Fast Facts About Honey Bee Drones

WACKY FACT ABOUT DRONES: A honey bee drone has no father, but he does have a grandfather! |
Drones are 'haploid',
having been reared from an unfertilised egg. As a result, a drone has only
half the
chromosomes of a worker bee or queen bee - the drone has 16 chromosomes, workers
and queens have 32. (That honey bee drones are haploid was first
discovered in 1845 by a Polish apiarist, named Jan Dzierżon - often
described as the "father of modern apiculture" - see History Of Beekeeping).
Being haploid means that drones can have a grandfather and grandsons, but a drone cannot have sons!
To explain further:
Drones come from unfertilized eggs (they are 'haploid'), meaning that no male (drone) was needed in order for the queen to produce more males - in other words, they are formed without a male 'parent'. (In fact, at various times, female worker bees can and do also create drones, despite the fact that they do not mate with males - they are referred to as 'Drone Laying Workers').
But what about the queens - the mother of all the drones?
In order for a queen to produce new queens, eggs must be fertilized, for which drone bees are necessary. This means that the queen (the "mother" of the drone), has a "father" - obviously a drone. This means that any drones produced by the queen, actually have a "grandfather" (i.e. the "father" of the queen) - more specifically, a "maternal grandfather" (the father of the queen).
Put yet another way and more succinctly:
The queen who laid the drone eggs, is the offspring of
an egg fertilized by a drone (male). Drones themselves, however, are
the offspring of eggs that have not been fertilized by a male, and they are therefore, fatherless.
This scenario, whereby offspring are reared from unfertilized eggs, is referred to by biologists as ‘parthenogenesis’.
Each honey bee colony will produce several hundred drones (in contrast with the thousands of workers).
On warm and sunny afternoons during the mating season, sexually mature
drones, fly out of the nest (or hive) and congregate with other drones
high in the
air, to form a cloud of bees. There may be as many as 11000
drones from up to 240 different colonies (5).
These clouds of drones can measure between 30 and 200m in diameter, and be located 10–40 m above ground (6).
About one hour after the peak of drones’ departure from the hives,
virgin queen will also leave her hive for her nuptial flight, and join the drone congregation (7).
As soon as a virgin queen enters the congregation of drones, groups of drones are
attracted to her, first by olfactory cues (pheromones), and at shorter
range by visual cues.
Drones follow the virgin queen in a comet-like swarm each competing to approach and mate with the queen (8).
Usually, a queen mates within 15–30 minutes, and with just 10–20 of the thousands of drones, and each drone that mates with the queen will die after mating (9). This happens because the drone’s reproductive organs are torn away from its body, whilst the queen flies off, with the drones genitalia attached to her.
Drones may live for just a few short weeks with drones that mate with queens having shorter lives since they die after mating. However, it is also possible they may live up to 90 days(3).
They are expelled from their colonies by the end of summer, but in any case, by the end of autumn, there will be few or no drone bees around.
Unlike workers, the drone cannot sting.
