  8. A queen honeybee (Apis mellifera) has a special sack that she stores the sperm from her mating flight(s). She determines the gender of an egg by either fertilizing it or not at the time that the egg is laid. A fertilized egg produces a female worker bee, or another queen if the larva is fed royal jelly; an unfertilized egg produces a male drone bee. **A male honeybee does not have a father.** This is called haplodiploidy and isn't unique to the honeybee. All insects in the order of Hymenoptera are subject to this. You can associate this order with the Greek root word hymen, or membrane, and their membranous wings. Other members of Hymenoptera include wasps, ants, and other bees. *I'm a hobby beekeeper. Save the honeybees.
