Understanding Hive Hierarchy
A honey bee colony brings together thousands of individuals whose lives depend on one another. The queen produces the next generation, workers maintain the nest and gather its resources, and drones carry the colony’s genes into future generations. Understanding how these roles fit together helps explain everything from honey production to swarming and winter survival.
Although we often talk about a hive’s “hierarchy”, the queen does not issue orders. Colony organisation emerges through chemical signals, communication and the responses of individual bees to conditions around them. This article explores the western honey bee, Apis mellifera, the species commonly kept by UK beekeepers.

An established colony normally contains one laying queen, many thousands of female workers and, during the reproductive season, male drones. Their numbers change with the season, food supply and colony strength. The colony also contains brood: the eggs, larvae and pupae developing into adult bees.
The queen is a reproductive female, usually recognisable by her long, tapering abdomen. Workers are smaller females equipped for tasks such as collecting pollen, producing wax and feeding larvae. Drones are males with broader bodies and particularly large eyes that meet at the top of the head.
Strictly speaking, the colony is the community of bees, while the hive is the structure in which a managed colony lives. Understanding the colony means looking beyond the hive itself to the relationships that keep its inhabitants alive.

The queen’s role in the colony
Producing the next generation
The queen is the colony’s principal egg layer. During strong spring and summer growth, a productive queen may lay around 1,500–2,000 eggs a day, although this is a peak rather than a constant rate. Her output depends on the season, available food, space and the workers’ capacity to rear brood.
In the normal honey bee life cycle, fertilised eggs develop into females, which may become workers or queens. Unfertilised eggs develop into male drones. The queen therefore produces both the workforce that sustains her colony and males that contribute to reproduction beyond it.
Mating and storing sperm
A young virgin queen leaves the hive to mate in flight, usually with several drones over one or more flights early in her adult life. She stores sperm in an organ called the spermatheca and uses it to fertilise eggs throughout her laying life. Once established, she does not routinely leave the hive to mate again.
Mating with multiple drones gives the colony workers with different fathers. This genetic diversity creates variation within the workforce and is an important feature of honey bee biology.
Communicating through pheromones
Queens produce pheromones: chemical signals detected by other bees. These communicate information about the queen’s presence and reproductive condition. Workers attending her form a retinue, feeding and grooming her and helping distribute her chemical signals through their interactions with other bees.
Queen pheromones, together with signals from brood, help regulate worker reproduction and colony behaviour. They do not amount to instructions about which flowers to visit or which cells to clean. Those activities depend on information shared throughout the colony.
How a new queen develops
Queens and workers both develop from fertilised eggs. A queen is reared from a young female larva receiving specialised care and abundant queen food, commonly called royal jelly, in a queen cell. Nutrition and the rearing environment influence her development into a reproductive adult.
An adult worker cannot become a queen. The developmental difference is established while the bee is immature. A queen can live for several years, although colonies and beekeepers may replace her sooner.

Workers and the running of the hive
Workers make up the great majority of adult bees. Their duties change broadly with age, as their bodies develop and the needs of the colony shift. Younger workers generally work inside the nest; older workers are more likely to forage.
This is a flexible pattern. Tasks overlap, not every worker performs every job, and bees can change roles in response to shortages. A colony that loses many foragers, for example, may recruit younger bees to forage earlier.
Cleaning and caring for brood
Newly emerged workers begin with duties such as cleaning brood cells, preparing them for further use. Nurse bees feed developing larvae with food produced by glands in their heads. This care connects the queen’s egg laying to successful population growth: eggs alone cannot maintain a colony without workers able to rear them.
Workers also remove debris and dead bees. Hygienic behaviour can include detecting and removing unhealthy brood, helping limit the spread of some diseases and parasites. Its effectiveness varies between colonies, and it does not remove the need for bee health monitoring.
Building comb and processing food
Workers secrete wax from glands beneath their abdomens and shape it into comb. These cells provide space for brood and food stores. Producing and maintaining comb requires energy, so construction depends partly on suitable conditions and available resources.
Returning foragers pass nectar to other workers for processing. Enzymes and the removal of water help transform it into honey, which can be stored for later use. Pollen supplies protein and other nutrients needed for brood rearing and healthy workers.
Regulating temperature and defending the nest
Workers help keep developing brood at a suitable temperature, generally around 34–35°C. They generate heat through muscular activity and use ventilation and water evaporation to help cool the nest when needed.
Guard bees monitor the entrance and respond to intruders, including bees attempting to rob stores. Workers can sting in defence of the colony, and alarm pheromones can recruit further defenders. Defence is one part of a worker’s contribution alongside feeding, cleaning and foraging.
Collecting resources outside the hive
Foragers collect nectar, pollen, water and plant resins used to make propolis. Each serves a different need: nectar provides energy, pollen supports nutrition, water supports cooling and feeding, and propolis is used within the nest, including to seal small gaps.
Successful foragers can communicate a food source’s direction and distance through the waggle dance. Other bees combine this information with scent and their own experience to locate the resource. This allows a colony to direct more effort towards worthwhile forage without a central organiser.
