thing that happens is all of the drone's blood in his body rushes to his endophallus which causes him to lose control over his entire body. His body falls away, leaving a portion of his endophallus attached to the queen which helps guide the next drone in the queen. Honey bee queen breeders may breed drones to be used for instrumental insemination or open mating. A queen mating yard must have many drones to be successful. In areas with severe winters, all drones are driven out of the hive in the autumn. A colony begins to rear drones in spring and drone population reaches its peak coinciding with the swarm season in late spring and early summer. The life expectancy of a drone is about 90 days. Although the drone is highly specialized to perform one function, mating and continuing the propagation of the hive, they may have other purposes. All bees, when they sense the hive's temperature deviating from proper limits, either generate heat by shivering, or exhaust heat by moving air with their wings—behaviours which drones share with worker bees. Behavior Drones do not exhibit typical worker bee behaviors such as nectar and pollen gathering, nursing, or hive construction. While drones are unable to sting, if picked up, they may swing their tails in an attempt to frighten the disturber. In some species, drones buzz around intruders in an attempt to disorient them if the nest is disturbed. Drones fly in abundance in the early afternoon and are known to congregate in drone congregation areas a good distance away from the hive. Mating and the drone reproductive organ The drone endophallus is designed to disperse a large quantity of seminal fluid and spermatozoa with great speed and force. The endophallus is held internally in the drone. During mating, the organ is everted (turned inside out), into the queen. The eversion of the endophallus is achieved by contracting abdominal muscles, which increases hemolymph pressure, effectively "inflating" the endophallus. Cornua claspers at the base of the endophallus help to grip the queen. Mating between a single drone and the queen lasts less than 5 seconds, and it is often completed within 1–2 seconds. Mating occurs mid-flight, and above ground. Since the queen mates with 5–⁠19 drones, and drones die after mating, each drone must make the most of his single shot. The drone makes first contact from above the queen,
