No insect called a “king bee” exists in a honey bee colony. The term crops up in casual conversation and old folklore, but it reflects a misunderstanding of how bee societies work. Male honey bees are called drones, and their role could hardly be more different from what “king” implies. They do not rule, they do not guard, and they cannot sting. Their primary purpose is to mate with a queen from another colony, and after that single act, they die. Understanding what drones actually do, how they live, and why they exist reveals a story far stranger than the idea of a male counterpart to the queen.
Why Honey Bees Have No King
In many animal kingdoms, a dominant male partners with a female and both contribute to reproduction and colony leadership. Honey bees evolved along a completely different path. A honey bee queen mates not with one male but with many. She typically flies to a gathering spot, mates with a dozen or more drones from unrelated colonies, and stores their sperm for the rest of her life. Genetically diverse colonies with roughly fifteen father lines founded new colonies faster, stored more food, and survived winter better than genetically uniform colonies with just one father line.1PubMed. Genetic diversity in honey bee colonies enhances productivity and fitness This means a single “king” would actually be a liability: having one father for an entire colony’s workforce makes the colony weaker, not stronger.
The sex-determination system reinforces why males never become rulers. Female bees develop from fertilized eggs and carry two sets of chromosomes. Males develop from unfertilized eggs and carry only one set, inheriting genes solely from their mother. A drone has no father. This system means the queen controls whether an egg becomes female (by fertilizing it) or male (by leaving it unfertilized). Drones are produced when the colony needs them, usually in spring and early summer, and they are expendable by design.
What a Drone Looks Like
Drones are noticeably different from worker bees. They are stockier, with a barrel-shaped abdomen, and they lack a stinger, pollen baskets, and functional wax glands. But the most dramatic difference is their eyes. A drone’s compound eyes are enormous, meeting at the top of its head, and they are built for one job: spotting a queen in flight. The upper region of the drone eye has enlarged facets, smaller angles between visual units, and even a different set of light-sensitive pigments compared with the lower region or a worker bee’s eye.2Tissue and Cell. Functional morphology of the divided compound eye of the honeybee drone (Apis mellifera) In effect, the drone’s eye is split into a specialized upper zone tuned for detecting a small moving object against bright sky and a lower zone that resembles a worker’s general-purpose eye.
This pattern is not unique to the western honey bee. Across multiple honey bee species, drones consistently have much larger eyes with bigger dorsal facets than workers or queens. In the giant honey bee, the enlarged facets appear to be an adaptation for mating flights that happen in low light around dusk.3PubMed Central. Sex and caste-specific variation in compound eye morphology of five honeybee species The entire body plan of a drone is shaped by mating, not by hive work.
What Drones Do Inside the Hive
For most of their lives, drones stay inside the colony. They cannot forage, and they rely on worker bees to feed them. This dependence led to a longstanding reputation as pure freeloaders, but research shows that drones do contribute something tangible: heat. Honey bee brood needs to be kept at a narrow temperature range to develop properly, and drones help warm the nest. About 30 percent of drones older than eight days actively raised their thorax temperature more than a degree above their abdomen, a sign of deliberate heat generation. Even the youngest drones, which are less active heaters individually, clustered on the brood nest at roughly three and a half times the density of older drones, meaning their passive warmth still mattered.4PubMed Central. Contribution of honeybee drones of different age to colonial thermoregulation
That said, the colony clearly views drones as seasonal assets. As autumn approaches and resources dwindle, worker bees stop feeding drones and physically push them out of the hive. Recent research shows this eviction is not random. Workers selectively target drones that are lighter in weight or whose immune system has been challenged, apparently reading chemical cues on the drone’s body surface. Crucially, the unhealthy drones do not leave on their own. Workers decide who goes.5Behavioral Ecology and Sociobiology. To house or oust: Honey bee (Apis mellifera) colonies can evaluate and evict drones of low quality The colony invests in drones only as long as those drones might successfully mate and pass along good genes.
The Mating Flight and Drone Congregation Areas
A drone’s defining moment is his mating flight. Drones from many different colonies converge on specific aerial gathering spots called drone congregation areas, or DCAs. These locations tend to be reused year after year, even though the individual drones are new each season. Landscape analysis shows that the probability of a spot being a DCA can be predicted by terrain orientation, nearby urban cover, and trail density. At a 400-meter radius, combining those three features predicted about 80 percent of DCA locations.6Journal of Insect Science. Landscape analysis of drone congregation areas of the honey bee, Apis mellifera How successive generations of drones find these same spots remains one of the genuine mysteries in bee biology, since no individual drone lives long enough to teach the next generation.
Part of the answer involves pheromones. In walking-simulator experiments, drones were drawn to the scent of other drones and to 9-ODA, a component of queen pheromone. Interestingly, the full queen-mandibular-pheromone blend and the odor of worker bees had no effect on drone behavior in the same tests.7Journal of Experimental Biology. Honeybee drones are attracted by groups of consexuals in a walking simulator Additional evidence suggests that drones emit pheromones that attract still more drones, creating a self-reinforcing swarm at these sites.8Scientific Reports. Virgin queen attraction toward males in honey bees A virgin queen flying through one of these clouds mates with several drones in quick succession. Each drone that mates with her dies immediately afterward, his reproductive organs torn away during the process.
The system also serves as an inbreeding barrier. Genetic analysis of drone congregations in the stingless bee Trigona collina found that males in a single swarm came from an estimated 132 different colonies, and no drone had a genotype suggesting it originated from the colony it was gathered near.9PubMed. Genetic structure of nest aggregations and drone congregations of the southeast Asian stingless bee Trigona collina By drawing drones from a wide area and mixing them, congregation sites ensure queens mate with unrelated males.
Drone Quality and Nutrition
Not all drones are equal, and the colony’s nutritional state during spring has a measurable effect on male fitness. Colonies given supplemental sugar syrup and protein produced drones that were heavier and had larger abdomens. Colonies with no supplemental feeding produced drones with significantly less semen and lower sperm viability.10Journal of Economic Entomology. Optimizing Drone Fertility With Spring Nutritional Supplements to Honey Bee (Hymenoptera: Apidae) Colonies For beekeepers, this matters: a poorly nourished colony’s drones may successfully mate with a queen but pass along sperm of low quality, which can affect the next generation of workers.
In commercial queen-breeding operations, the question of how many drones should contribute to a queen’s sperm supply receives careful attention. Programs that use instrumental insemination can control this variable precisely, but the evidence suggests that optimizing the number of drones per queen offers only modest gains over simply ensuring a large, healthy drone population is available for natural mating.11PubMed Central. The number of drones to inseminate a queen with has little potential for optimization of honeybee breeding programs Genetic diversity across many father lines, as mentioned earlier, matters more than getting the donor count exactly right.
Why Varroa Mites Love Drone Brood
Drones are magnets for one of the honey bee’s worst parasites. Varroa mites strongly prefer to invade drone larvae over worker larvae, and the difference is dramatic: in side-by-side tests, the rate of mite infestation per cell was on average more than eight times higher in drone brood.12Apidologie. Preference for drone brood cells by Varroa jacobsoni Oud in colonies of Apis mellifera carnica This preference becomes even more pronounced when drone brood is scarce, suggesting the mites are actively seeking it out rather than simply ending up there by chance.13Journal of Insect Science. Understanding the Enemy: A Review of the Genetics, Behavior and Chemical Ecology of Varroa destructor, the Parasitic Mite of Apis mellifera
The reason likely comes down to development time. Drone brood takes about three days longer than worker brood to emerge, giving the mites extra time to reproduce inside the sealed cell. This quirk has practical consequences for beekeepers. One common Varroa management technique involves placing a frame of drone comb in the hive, letting the queen lay drone eggs in it, waiting for the cells to be sealed and infested, then removing and freezing the frame. The approach sacrifices a batch of drones but takes a significant number of mites out of the colony. It works precisely because drones, not workers, are the mite’s preferred host.
Stingless Bee Males and Their Congregations
The honey bee is not the only social bee with mass male gatherings. Stingless bees, a large and diverse group of tropical species, also form reproductive aggregations. A review of at least 65 documented stingless bee aggregations found that about 71 percent involved a single species, while 29 percent included males from two or more species showing up at the same site.14PubMed Central. An Alien in the Group: Eusocial Male Bees Sharing Nonspecific Reproductive Aggregations In these mixed-species congregations, only about 18 percent of the “alien” males were closely related to the host species, meaning most interlopers were distantly related bees that apparently stumbled into the wrong gathering.
The probability of a male stingless bee joining another species’ aggregation was estimated at roughly 21 percent, which could happen by chance alone. These findings hint that the chemical and visual cues guiding males to congregation sites are not perfectly species-specific, at least in stingless bees. The reproductive system still works because queens and drones of the right species ultimately find each other within the crowd, but the process is messier than the tidy picture sometimes painted of insect mating behavior.
Sex Mosaics and Genetic Oddities
The same reproductive system that makes drones haploid occasionally produces something genuinely bizarre: gynandromorphs, or sex mosaics. These are individual bees that contain both male and female tissue in the same body. Researchers collected 11 newly emerged bees from a single colony that appeared to be gynandromorphs. Upon genotyping, 10 of the 11 turned out to be true sex mosaics, with different body parts tracing to different paternal origins. Some individuals had tissue from as many as three different fathers, meaning multiple sperm contributed to what became a single organism.15PubMed Central. Sex mosaics in the honeybee: how haplodiploidy makes possible the evolution of novel forms of reproduction in social Hymenoptera These bees are rare and not functional in colony life, but they reveal just how much reproductive flexibility is built into the honey bee’s genetic system.
Termite Kings Are Real
If you are looking for a social insect that actually has a king, termites are the place to look. Unlike bees, termite colonies are founded by a pair: a queen and a king. The king lives alongside the queen for the colony’s entire lifespan, mating with her repeatedly over years or even decades. Both reproductive termites appear to have biological machinery that supports their remarkable longevity. In the termite Prorhinotermes simplex, researchers found that kings and queens had elevated telomerase activity in their body organs compared with workers and soldiers. Telomerase helps maintain the protective caps on chromosomes, and its upregulation in reproducing termites contrasts sharply with the pattern in most adult animals, where telomerase is suppressed in non-reproductive tissues.16PubMed Central. Long-lived termite kings and queens activate telomerase in somatic organs A termite king is a true co-ruler: he shares the queen’s chamber, contributes genetically to every generation, and lives as long as she does. Nothing in bee biology comes close to this arrangement.
Territorial Males in Solitary Bees
While honey bee drones are passive and communal, males of some solitary bee species are aggressively territorial in ways that might feel more “kingly.” Male eastern carpenter bees establish territories at nest sites, food plants, and landmarks like boulders and buildings. Each male hovers within a small space and defends a roughly 20-meter attack radius around it, chasing away other males and flying toward females, other insects, birds, and even airplanes.17Tissue and Cell. Male territoriality in the carpenter bee Xylocopa virginica virginica These males are large, loud, and intimidating to humans, but like honey bee drones, they lack a functional stinger and are harmless. Their territorial behavior is purely about access to mates, not about defending a colony or exercising authority. The “king bee” label sometimes gets applied to these conspicuous males by people who encounter them buzzing aggressively around porches and garden sheds, but the behavior is sexual competition, not governance.
Carpenter bee territoriality also illustrates how differently male reproductive strategy can play out across bee species. A honey bee drone leaves the colony, joins a congregation of thousands, and hopes to be one of the lucky few that catches a queen in midair. A carpenter bee male stakes out a patch of real estate and confronts every moving object that enters it, mating with females that pass through. Both strategies have the same evolutionary goal, but the social context could not be more different. The honey bee drone’s world is anonymous and communal; the carpenter bee male’s world is personal and combative.
