European Honey Bee
Apis mellifera 2014-10-20 The queen stores sperm from her (deceased) drones in her body and can fertilize eggs as she lays them. Fertilized ones become female workers, the ones you see buzzing around flowers during the day. Unfertilized eggs become male drones, which mate with virgin queens to begin new colonies, then die. Queens are just workers that were given a special diet of royal jelly all through their immature stages. All larvae are fed royal jelly at first, before being switched to honey and pollen, but if a female is fed royal jelly past a certain point in her life cycle, she is transformed, gremlin-like, into a queen. These virgin queens then take off along with some drones to begin a new colony elsewhere.
