Worker and Drone Bees: What the Other 99 Percent Actually Do

Open a strong hive in June and you are looking at roughly 40,000 to 60,000 bees, of which about 95 percent or more are female workers, a few hundred to a couple of thousand are drones, and exactly one is a queen. Every bee you handle on a frame, every bee that stings you, every bee at a flower, every bee fanning at the entrance is a worker. She is a fully female bee with undeveloped ovaries, suppressed by the queen's pheromone and by brood pheromone from doing the one job she is not built for.

What she can do instead is nearly everything. She has brood food glands in her head, wax glands under her abdomen, scent glands at the tip of it, pollen baskets on her hind legs, a barbed sting, a honey stomach, and a set of behaviors that switch on and off in sequence as she ages. It is more useful to think of a worker not as a bee with a job but as a bee that becomes a series of different machines across six weeks, each stage triggered by physiological changes and adjustable to colony need (Wikipedia: worker bee). If you want this material at book length and properly illustrated, The Beekeeper's Bible ($19.60) is the reference we reach for.

The queen's side of this system, how she is made and what her pheromone does to all these workers, is the companion page: queen bee biology.

This sequence, called temporal or age polyethism, is the single most useful framework for reading a colony. Approximate ages, because bees do not carry calendars.

Age (days after emerging)	Job	What you see on the frame
1 to 3	Cell cleaning	Small fuzzy bees head-down in empty cells, polishing them for the queen
3 to 12	Nurse bee	Bees head-down over open larvae, feeding brood food from head glands
7 to 18	Wax building and comb work	Festooning chains hanging across gaps, fresh white comb appearing
10 to 18	Nectar receiving, ripening, fanning	Bees passing droplets mouth to mouth, fanning at the entrance and on combs
12 to 20	Housekeeping and undertaking	Debris and dead bees carried out the entrance and dropped away from the hive
18 to 21	Guard duty	Alert bees at the entrance challenging arrivals, wings up, forelegs raised
~21 to death	Forager	Bees leaving and returning loaded with pollen or nectar, dancing on the comb

The important qualification: this is a default schedule, not a rota. Colonies adjust it aggressively. Strip a hive of its foragers, by moving it or by a pesticide hit, and nurse bees will mature early and start foraging days ahead of schedule. Flood a colony with brood and some foragers will revert, regenerating brood food glands and going back to nursing. That plasticity is why a colony survives disruptions that would cripple a rigidly organized system, and it is why a strong colony recovers from a bad week faster than you expect.

If you are teaching this sequence to a child rather than memorizing it yourself, the National Geographic Kids Bees reader ($5.57) covers the same job progression at an early reading level, and it costs less than a jar of honey.

A newly emerged worker is pale, fuzzy, unsteady, and immediately put to work on the least glamorous job in the hive: cleaning and polishing the cell she just chewed out of, and every other empty cell nearby. Cells must be scrubbed of cocoon remnants and debris and given a thin propolis varnish before the queen will lay in them. She inspects; if the cell is not ready, she moves on.

This is not busywork, it is a rate limiter on the whole colony. A queen capable of 1,500 eggs a day cannot lay 1,500 eggs a day if the young bees have not prepared 1,500 cells. When beekeepers see a queen laying below her ceiling in a strong colony, prepared comb is one of the usual culprits, along with a honey-bound brood nest.

Cell cleaning also folds into hygienic behavior, the heritable trait where workers detect, uncap, and remove diseased or mite-infested pupae. That trait is one of the most valuable things you can select for in a queen, because it works against varroa and foulbrood without a single treatment. It is a big part of why breeder stock selection matters, covered in types of honey bees.

Around day three, a worker's hypopharyngeal glands, a pair of glands filling much of her head, come online and begin producing brood food. She becomes a nurse, and for the next week or so her life is feeding larvae, up to a thousand visits per larva across its development, checking cells constantly and adjusting food to the larva's age and caste. This is where royal jelly comes from, and it is why the caste system is a nursery decision rather than a genetic one.

Nursing has a hard requirement: protein. Those glands only develop properly if the young bee eats substantial pollen in her first days. A colony without pollen income or stored bee bread cannot produce good nurse bees, and a colony without good nurse bees cannot rear good brood, whatever the queen does. This is the entire reason beekeepers feed pollen substitute in late winter and early spring, and the case for and against it is in pollen patties and substitutes.

Nurse bees also carry the highest vitellogenin load of any summer bee, a storage protein that will matter enormously later in this article. Hold that thought.

Around the second week, four pairs of wax glands on the underside of the abdomen become active, secreting beeswax as small transparent scales. Workers gather in hanging chains, called festooning, across the space they intend to fill, and build comb downward: hexagonal cells at a precise 5.4 millimeters or so across for workers, wider for drones, at an angle that keeps honey from running out.

Wax is metabolically expensive. The commonly cited figure is that bees consume on the order of six to eight pounds of honey to produce one pound of wax, which reframes a lot of beekeeping decisions. It explains why drawn comb is the most valuable asset in an apiary, why an extractor that returns comb intact is worth its price, and why a colony given only foundation in a dearth will simply not build. The extractor economics are in best honey extractors, and the foundation choice in frames and foundation.

Wax glands are also on a timer: they atrophy as the bee ages toward foraging. A colony full of old foragers and short on middle-aged bees will not draw comb well no matter how strong the flow, which is a common and confusing observation for beekeepers who split late in the season.

Middle-aged workers run the processing plant. They meet returning foragers at the entrance and take the nectar load by mouth, then work it in droplets on their mouthparts, adding enzymes and exposing it to hive air before depositing it in cells. They then run the drying operation: fanning with their wings to move air across open cells until moisture drops to roughly 17 to 18 percent, at which point the honey is ripe and gets a wax cap. The whole conversion is covered in detail in how bees make honey.

How fast foragers get unloaded is itself a colony signal. When receivers are slow, foragers reduce recruitment dancing, which throttles the whole foraging effort to match processing capacity. It is a feedback loop, not a hierarchy, and it is one of the most elegant pieces of colony organization there is.

The same age group handles sanitation. Undertakers carry dead bees out and drop them well away from the entrance, workers remove debris, and propolis is applied to seal cracks and varnish surfaces. A colony that stops removing its dead is a colony in serious trouble, which is one of the tells in how to diagnose a deadout.

Just before she starts flying, a worker does a short tour as a guard. Guards stand at the entrance in a distinctive posture, forelegs raised, antennae forward, and check every arriving bee by scent against the colony's own odor. Nestmates pass; robbers from other hives, wasps, and beetles get challenged. During a dearth, when robbing pressure spikes, the guard force expands sharply and a hive that was gentle in June becomes hard to open in August.

When a guard commits, she stings, and a worker's sting is barbed. It anchors in mammalian skin and tears free from her abdomen along with the venom sac, which continues pumping, and she dies within minutes. That suicide is only rational for a social insect defending a colony: the individual is nearly worthless, the nest is everything. The sting also releases alarm pheromone, a banana-scented signal that marks the target and recruits more defenders, which is exactly why a single sting near the entrance often becomes several. Handling that, and the first-aid side, is in the bee sting safety guide (Wikipedia: alarm pheromone).

Guards also fan Nasonov pheromone from a gland at the tip of the abdomen to guide returning foragers and, famously, to guide a swarm to a new home. A row of bees at the entrance with abdomens tipped up and wings blurring is scenting, not defending, and it is how swarm traps work at all.

At around three weeks a worker becomes a forager, and her physiology changes to match: brood food glands shrink, wax glands atrophy, flight muscles and metabolic machinery ramp up. She takes orientation flights first, those late-afternoon clouds of bees hovering and facing the hive that so often panic new beekeepers, learning the landmarks around her entrance. Then she starts flying for a living.

Foragers specialize. Most collect nectar or pollen, generally sticking to one flower type per trip, which is precisely what makes honey bees useful pollinators. Others collect water, for cooling the hive and diluting stored honey for brood food, and a few collect propolis, the sticky plant resin used as sealant and antimicrobial varnish. Water foragers are the reason a neighbor's pool becomes an issue and why a dedicated water source matters, covered in bee water stations.

Foraging is fatal work. A forager flies until her wings physically wear out, and the commonly cited figure is roughly 500 miles of flight in a lifetime. Wing wear is visible: hold a late-summer frame up and the ragged, translucent, hairless bees are the old foragers, versus the fuzzy dark young bees around the brood. She usually dies in the field, which is why colonies do not fill up with corpses despite losing a thousand bees a day.

Twenty thousand foragers searching an area of roughly 8,000 acres, with no map and no manager, is a serious logistics problem. The colony's solution is the waggle dance. A forager returning from a good source runs a figure eight on the vertical comb, and the straight waggle run in the middle carries the information: the angle of the run relative to straight up encodes the direction of the source relative to the sun's current position, and the duration of the run encodes the distance. Followers press against her in the dark, reading it by touch and vibration, and fly out (Wikipedia: waggle dance).

The dance floor works as a market. Richer sources earn longer, more vigorous dancing and recruit more foragers; declining patches stop being advertised and the workforce reallocates within hours. Layer in the unloading feedback described above and you get a self-regulating system that constantly reallocates thousands of workers toward the best available forage without anyone deciding anything.

For a beekeeper this explains a lot: why supers fill in bursts rather than steadily, why your colonies abandon your flower bed the day the basswood opens, and why a strong colony out-earns two weak ones rather than matching them. It is also the single best thing to show a child through an observation hive, which is one reason we like observation hives for teaching.

Put real numbers on the workforce and the price of honest local honey stops looking high. A forager carries tens of milligrams of nectar per trip, gathered from fifty to several hundred flowers, and burns a meaningful share of that cargo as flight fuel getting home. Nectar arrives at maybe 20 to 40 percent sugar and has to be concentrated to about 82 or 83 percent, so most of what she hauled evaporates away.

Unit	Commonly cited figure
One worker's lifetime honey production	about 1/12 of a teaspoon
Flower visits behind one pound of honey	on the order of 2 million
Flight distance behind one pound of honey	tens of thousands of miles, collectively
Honey consumed to make one pound of wax	roughly 6 to 8 pounds
Foraging radius, practical	usually within 2 miles, capable of 3 to 5
Winter stores a cold-climate colony needs	roughly 40 to 60 pounds

Two beekeeping conclusions fall out. First, harvest only true surplus: the colony banked those stores as winter fuel, and taking into the 40 to 60 pound reserve is not thrift, it is a deadout in February. The honest yield model is in how much honey per hive. Second, if you sell honey, this arithmetic is your pricing story and your best sales pitch, which is exactly how we frame it in how to sell honey.

Here is the fact that surprises even experienced beekeepers. A worker born in June lives about six weeks. A worker born in late September lives four to six months, right through the winter to the following spring. Same species, same genome, often the same mother. The difference is physiological, and it is one of the most important pieces of biology a beekeeper can understand.

Bees reared in late summer and fall, when brood rearing slows and pollen is being stored rather than consumed at full tilt, develop enlarged fat bodies and very high levels of a storage glycoprotein called vitellogenin. Vitellogenin serves as a protein reserve, supports brood food production, and is associated with immune function and resistance to oxidative stress. These so-called winter bees, sometimes called diutinus bees, are essentially built with a full fuel tank and then asked not to spend it: they do not forage hard, they cluster, they shiver to keep the colony warm, and they survive to rear the first spring brood (Wikipedia: vitellogenin).

The beekeeping implication is blunt and it is the reason August matters more than any other month. Winter bees are reared in roughly August and September. Varroa mites feed on the fat body of developing and adult bees, precisely the tissue winter bees depend on, and they transmit viruses that shorten life further. A colony carrying a high mite load in late summer rears compromised winter bees, and those bees die in January no matter how much honey is stacked above them. That is the mechanism behind the classic strong-in-October, dead-in-February deadout, and why treatment timing is the subject of its own page: when to treat for varroa (Bee Health, eXtension).

Worker ovaries are not absent, only suppressed, held down by queen mandibular pheromone and by pheromone from open brood. Remove both for long enough, typically two to four weeks of hopeless queenlessness with no young larvae, and some workers develop functional ovaries and begin laying. Because they never mated, they can only lay unfertilized eggs, which means drones, in worker-sized cells.

The signature on the frame is unmistakable once you have seen it: multiple eggs per cell, often three or four, stuck to the cell walls rather than centered on the floor, because a worker's abdomen is too short to reach the bottom. Cappings across the brood area are bullet-shaped and domed, standing proud of flat worker comb. Compare that with a drone-laying queen, who lays one egg per cell, centered and correct, and simply cannot fertilize any of them. Both produce drone brood in worker comb; only one of them can be fixed by introducing a queen.

Laying-worker colonies usually reject introduced queens, sometimes killing several in succession, because dozens of pseudo-queens now compete chemically. The honest options are all slow: repeated frames of open brood from a strong colony over two or three weeks to re-establish brood pheromone, then a queen introduction, or the pragmatic route of combining the remnant over newspaper with a queenright hive, which is how to combine two hives. The prevention is simpler than the cure: check for eggs every inspection, and never let a hive sit queenless for a month.

Now the males. A drone develops from an unfertilized egg, which means he is haploid, carrying only his mother's genes: he has a grandfather but no father, and every sperm cell he produces is genetically identical. He develops in a wider cell, takes 24 days from egg to emergence, and comes out noticeably larger than a worker, stocky and blunt-bodied, with enormous wraparound eyes that meet on top of his head and a loud, unmistakable buzz.

What he does not have is nearly everything else. No sting, so he is entirely harmless to handle and is the bee to hand a nervous visitor. No pollen baskets. No wax glands. No functional brood food glands. His tongue is too short to feed efficiently from flowers, so he is largely fed by workers or helps himself to stored honey. He does not clean, guard, nurse, build, or forage. In colony accounting he is pure overhead, and colonies carry him anyway, a few hundred to a couple of thousand in spring and summer, because the alternative is genetic extinction (Wikipedia: drone bee).

Drones mature sexually about ten to fourteen days after emerging, then fly out on warm afternoons to drone congregation areas, patches of open air where thousands of males from colonies across the landscape gather waiting for virgin queens. They come home to eat and go back out the next afternoon, a routine that lasts a few weeks.

If a drone succeeds, it is the last thing he does. Mating happens in flight, and the mechanics are violent: his endophallus everts explosively into the queen, the process is audible as a distinct pop, and he is paralyzed and falls away, leaving part of his anatomy behind as a mating sign that the next drone removes before adding his own. He dies within minutes.

Given roughly ten to twenty drones per queen and many thousands of drones per drone congregation area, the individual odds are terrible. The vast majority of drones never mate at all and die of cold or eviction instead. From the colony's perspective this is a lottery run at scale, and the entry fee is the honey those thousands of drones consumed all summer.

The queen's side of that same afternoon, the flight, the spermatheca, and the lifetime of stored sperm it produces, is in queen bee biology.

In late summer and autumn, as the flows end and the colony starts rationing for winter, the workers do the arithmetic and act on it. Drones are pushed away from stores, harassed, stopped from being fed, and finally dragged and driven out the entrance. You will find them dead or dying on the landing board and in the grass on a cool September morning. They cannot get back in, cannot feed themselves adequately, and do not survive the first hard nights.

It looks cruel and it is simply accounting. A drone eats through winter and contributes nothing, and there are no queens to mate in December. Colonies that keep drones through the winter are usually telling you something is wrong: a queenless colony, or one with a drone-laying queen or laying workers, often tolerates drones far later than a healthy hive does. Drones in a hive in December is a diagnostic flag, not a curiosity.

Come spring, the cycle restarts. Drone rearing ramping up in March and April is one of the earliest reliable signs a colony is preparing to reproduce, which in practice means preparing to swarm, since a colony will not swarm into a landscape with no drones to mate its daughter queens. Drone comb appearing at frame edges in early spring is your cue to start watching bottom bars for queen cells, and the response is how to prevent swarming.

It is easy to read the drone file and conclude he is a freeloader. That misreads the system badly. Drones are how honey bee genetics move at all. A colony's queen carries only her own line; the genetic diversity that makes her colony resilient arrives entirely through the dozen or more unrelated drones she met at a congregation area, each contributing a patriline of half-sisters with different strengths in thermoregulation, disease resistance, and foraging.

That is why local drone density is a real factor in queen quality. A queen mated in an area with many colonies gets a diverse, well-mated start; a queen flying in an isolated yard may come back poorly mated and fail within months. It is one of the strongest practical arguments for joining a local club and for keeping more than one colony, and it is the reason queen breeders manage drone-source colonies as carefully as they manage the breeder queen.

There is also a varroa angle worth knowing, because it cuts both ways. Varroa mites strongly prefer drone brood, since the longer 24-day capped period lets more mites mature. Some beekeepers exploit this with drone brood trapping, deliberately giving a colony drone comb and removing it once capped. It works as a supplementary tool and fails badly as a standalone strategy, and the honest comparison is in best varroa mite treatments.

One table to hold the whole colony in your head. For teaching it to a group, physical stages beat any chart, which is why the Safari Ltd honey bee life cycle set ($12.99) turns up on so many club outreach tables.

If you take one idea from this page, take this: the colony, not the bee, is the animal. A worker is a temporary organ that changes function as it ages and dies without consequence. The drone is a gamete delivery vehicle. The queen is reproductive tissue. What is actually alive, in the sense of persisting, learning, allocating resources, and reproducing, is the hive. Every good beekeeping decision follows from managing the superorganism rather than the insects. The vocabulary for all of it is in the beekeeping glossary, and the whole road into the hobby is how to start beekeeping.
