Drone
Drones are male bees. They are produced from unfertilized eggs (by parthenogenesis). They are characterized by eyes that are twice the size of those of worker bees and queens, and a body size greater than that of worker bees.Their main function in the hive is to be ready to fertilize a receptive queen. Mating occurs in flight, which accounts for the need of the drones for better vision. Although heavy bodied, drones have to be able to fly fast enough to catch up with the queen in flight. Should a drone succeed in mating it will soon die because the reproductive organ and associated abdominal tissues are ripped from the drone's body immediately after intromission occurs.
A drone is also a member of the Drones Club in the P.G.Wodehouse books, named for the fact that drones in a hive do little work.
A drone is also a term used to refer to Unmanned Aerial Vehicles.
