Bees, those happy little social animals, are actually hiding a fair amount of unpleasant behavior in their hives. For example, where the queen bee becomes too old, she is chased through the hive by other female bees until they kill her. Pretty much everyone knows that drone bees only mate and die. But did you know why? It's because their genitals explode during mating. Sad, but necessary if the drone is to set up a genital plug to prevent other drones from inseminating the queen. Ewww.
