The honey bee colony

A honey bee colony is not really a collection of individuals. It behaves more like a single living thing — a superorganism — in which thousands of bees co-operate so closely that the colony, not the bee, is the unit that survives, reproduces and overwinters. A lone worker dies within days; the colony can persist for years.

Understanding this is the foundation of good beekeeping. When you open a hive, you are reading the state of one organism: its population, its food stores, its health and its mood. Openbeehive helps you record what you see so that pattern emerges over time.

The three castes

A colony contains three kinds of bee, each with a distinct body, lifespan and job.

Caste	Number in colony	Develops in	Lifespan	Role
Queen	1 (normally)	~16 days	1–5 years	Lays eggs, holds the colony together with pheromones
Worker	10,000–60,000+	~21 days	6 weeks (summer), 4–6 months (winter)	All other work
Drone	0–several thousand (seasonal)	~24 days	A few weeks	Mating only

The queen

There is usually one queen per colony. She is the only fully developed female and the mother of nearly every bee present. In her prime she can lay up to 1,500–2,000 eggs a day — more than her own body weight.

The queen is not a ruler. She does not direct the colony; instead she binds it together chemically. Her queen mandibular pheromone signals to the workers that the colony is "queenright", suppressing the rearing of new queens and the development of laying workers. When that signal fades — because she has died, is failing, or the colony has grown too large for her scent to reach everyone — the workers respond by raising a replacement.

A queen mates only once in her life, over a few days early on, storing sperm for the rest of her years. In Openbeehive you can record each queen, her marking colour and year, and her origin. See Queens.

:::tip Queen marking Queens are often marked with a coloured dot following the international colour scheme, which records the year she was born. See Queen marking colours. :::

Workers

Workers are females whose reproductive development was switched off by their larval diet. They do everything except lay eggs and mate, and a worker's job changes with her age in a rough progression known as temporal polyethism:

• Days 1–3 — cleaning cells.
• Days 3–12 — nursing: feeding larvae and the queen.
• Days 12–18 — building comb, storing and ripening nectar, receiving foragers' loads.
• Days 18–21 — guarding the entrance.
• Day ~21 onwards — foraging for nectar, pollen, water and propolis until she dies, often literally worn out in the field.

This schedule is flexible. If a colony loses all its foragers, young bees mature faster; if it loses nurses, older bees can revert. The colony self-regulates.

Drones

Drones are male. They have no sting, do not forage and do not work in the hive. Their single purpose is to mate with virgin queens from other colonies, which they do in flight at drone congregation areas. A drone that mates dies in the act.

Drones are a seasonal luxury. Colonies rear them in spring and summer and evict them in autumn, when feeding non-productive mouths through winter would be wasteful. A laying-worker or drone-laying queen colony that produces only drones is a colony in trouble.

The brood nest and comb

At the heart of the hive is the brood nest: the area of comb where the queen lays and young bees develop. It is kept remarkably warm and stable — around 35 °C — by workers clustering and shivering their flight muscles.

Comb is built from wax secreted by glands on the workers' abdomens and shaped into hexagonal cells. The same comb serves several uses, arranged in a recognisable pattern:

• Brood in the centre, in a domed shape across several frames.
• A band of pollen ("bee bread") around the brood.
• Honey stored at the top and outer edges, capped with wax when ripe.

Brood develops through three stages: egg (3 days), larva (fed by nurses, then capped), and pupa (sealed in its cell until it emerges). Learning to read the brood pattern — solid and even versus patchy — is one of the most useful inspection skills. Record what you find in Inspections.

The annual population cycle

A colony's size rises and falls with the seasons, tracking the availability of forage.

• Late winter — the queen begins laying again; a small cluster starts to grow.
• Spring — explosive build-up; the population can multiply several times over. This is also swarming season, the colony's natural reproduction.
• Summer — peak population and the main nectar flow; honey is stored rapidly.
• Autumn — laying slows, drones are evicted, and the colony rears special long-lived "winter bees".
• Winter — no flight, no brood (or very little); the cluster lives on stored honey.

How a colony communicates

With no central control, the colony co-ordinates through chemistry and movement.

Pheromones are chemical messages. The queen's pheromone signals her presence and health; alarm pheromone (smelling faintly of bananas) recruits guards to a threat; brood pheromone tells nurses there are larvae to feed; the Nasonov scent helps lost bees find the entrance and helps a swarm regroup.

The waggle dance is how a forager tells her sisters where to find food. On the vertical comb she runs in a figure-of-eight, waggling along the central run. The angle of that run relative to straight up encodes the direction of the food relative to the sun; the duration of the waggle encodes the distance. It is one of the few known symbolic languages outside humans.

How honey is made

Honey is the colony's stored fuel. Foragers collect nectar — sugary water from flowers — in a special honey stomach. Back at the hive they pass it mouth-to-mouth to house bees, adding enzymes that begin converting the nectar's complex sugars into simpler ones.

The house bees then spread the nectar in cells and fan it with their wings, driving off water until the moisture content drops to around 18–20%. At that point it is stable and will not ferment, and the bees cap the cell with a wax lid. That capped, ripe honey is what beekeepers harvest the surplus of. See Honey harvest and record yields in Harvests.

How a colony overwinters

In cold climates the colony does not hibernate and does not heat the whole hive. Instead the bees form a tight winter cluster around what brood there is. Bees on the outside form an insulating shell; those inside generate heat by shivering, and the whole cluster slowly rotates so no bee stays cold for long. The centre may hold near 35 °C even when it is freezing outside.

The cluster runs entirely on stored honey, eating its way slowly upward through the combs over the months. Two things decide whether it survives: enough stores in the right place, and a population of healthy winter bees. This is why autumn feeding and varroa control matter so much.

:::caution Winter losses are real Even healthy-looking colonies can die over winter from starvation, disease or a heavy mite load entering autumn. Going into winter strong and healthy is far more important than any midwinter intervention. See Varroa and Feeding. :::

:::note Regional variation Colony behaviour varies with climate and subspecies. The cycle above describes a temperate-climate colony; in warmer regions brood rearing may never fully stop, and timings shift accordingly. Always calibrate to your own location and local mentors. :::
