European honey bee (Apis mellifera) Drone.
Drones are the male bees of the colony. Since they do not have ovipositors, they also do not have stingers. Drone honey bees do not forage for nectar or pollen. In some species, they are suspected of playing a contributing role in the temperature regulation of the hive. The primary purpose of a drone bee is to fertilize a new queen. Multiple drones will mate with any given queen in flight, and each will die immediately after mating; the process of insemination requires a lethally convulsive effort. Drone honey bees are haploid (having single, unpaired chromosomes) in their genetic structure and are descended only from their mother, the queen. They truly do not have a father. In essence, drones are the equivalent of flying gametes. In regions of temperate climate, the drones are generally expelled from the hive before winter and left to die of cold and starvation, since they are unable to forage, produce honey, or take care of themselves.
