The drone bees are the only male bees of a colony of honey bees. They can be easily identified from the workers, first of all by the pair of large bulging compound eyes. Furthermore, they are larger than the workers yet smaller than the queen. Also, there are fewer males in the hive in comparison to the workers and are rarely seen outside of the hive except in mating season where they seek out a young queen to mate with. As many as 20 or more males will mate with a virgin queen during her nuptial flight when he will perish in the act.
