Western honey bee

Apis melliferaEusocial, colony survives the winterStores a harvestable surplus

The bee behind essentially all the world's honey, and the one most people mean when they say 'bee'. Apis mellifera is a perennial eusocial insect that overwinters as a living cluster rather than dying back each year — which is the whole reason it stores honey in quantity, and therefore the reason it was ever domesticated. It is native to Europe, Africa and western Asia and has been carried by people to every continent except Antarctica.

Can it sting?

Workers can sting, and the sting is barbed: it lodges in mammalian skin and tears free from the bee, which then dies. This is genuinely suicidal defence and it is specific to defending the nest against large animals — a foraging honey bee on a flower has no interest in stinging and normally will not. The barb does not catch in insect cuticle, so a bee fighting a wasp stings repeatedly and survives. Queens have a smooth sting and use it only against rival queens. Drones have none.

How to recognise it

A slim, amber-and-brown striped bee about 12-15 mm long, with a distinctly wasp-waisted look compared with a bumblebee. Workers are noticeably less hairy than bumblebees, and the abdomen is banded rather than furry. Colour varies widely by subspecies: Italian bees (A. m. ligustica) are markedly yellow, while the northern European dark bee (A. m. mellifera) is close to black.

  • Slim, banded abdomen with visible amber and brown stripes rather than a coat of fur.
  • Pollen carried as a single flattened pellet on the outside of the hind leg — visible from several feet away, and the single most reliable field mark.
  • Flies with the legs tucked up; hoverflies hang motionless in mid-air in a way honey bees never do.
  • Two pairs of wings, hooked together in flight. Hoverflies and other true flies have one pair, and short stubby antennae.

Body length 1017 mm (typically 13 mm).

Biology

Social organisation

Eusocial, colony survives the winter

Overlapping generations, division of labour, and a colony that persists through winter as a cluster. Honey bees, and the reason they store honey at all.

Colony size at peak
20,00060,000 individuals
Colony lifespan
Indefinite. A colony is a continuous entity that can persist for many years, replacing its queen as needed, even though no individual worker lives more than a few months.
Winter
The colony forms a tight cluster and generates heat by shivering its flight muscles, holding the core near 20 °C even in hard frost and considerably warmer when brood is present. This is metabolically expensive and is paid for by eating stored honey — which is precisely what the honey is for.

Nesting
Wax comb in a cavity

Wild colonies choose enclosed cavities — hollow trees above all — of roughly 30 to 60 litres, preferably several metres up with a small entrance. They build vertical wax combs from scratch rather than using existing structure. Managed hives are an imitation of the tree cavity, with the combs made removable.

Lifecycle

  1. EggLaid singly, upright, in the base of a cell. A laying queen can produce more than a thousand a day at the height of the season, exceeding her own body weight.About 3 days for all castes.
  2. LarvaA legless grub, fed constantly by nurse bees. All larvae receive royal jelly at first; the ones that keep receiving it become queens. Caste is a consequence of diet, not of the egg.Roughly 5-6 days before the cell is capped.
  3. PupaSealed under a wax capping while the adult body is assembled.Development from egg to adult takes about 16 days for a queen, 21 for a worker and 24 for a drone.
  4. Adult workerWork is organised by age rather than assignment: cell cleaning first, then nursing brood, then wax building and food handling, then guarding, and finally foraging outside for the last week or two of life. The order is flexible — a colony that loses its foragers can push young bees forward and reverse the sequence.About six weeks in summer, when foraging wears them out. Winter bees are physiologically different and live for months.

Where it lives and what it does

Habitat
Extraordinarily adaptable: woodland, farmland, heath, scrub, gardens and dense cities. A colony needs a cavity, water, and forage within roughly 3 km, though bees will fly considerably further when they must.
Distribution
Native to Europe, Africa and western Asia, with around 30 recognised subspecies adapted to conditions from Norwegian winters to Saharan margins. Introduced by people to the Americas, Australia, New Zealand and across Asia, and now present nearly worldwide.
Behaviour
The famous behaviours are all consequences of being a perennial colony that must feed itself through a season when nothing flowers. Foragers recruit nestmates to a food source with the waggle dance, encoding direction relative to the sun and distance in the duration of the waggle run. Swarming — the colony's method of reproduction — sends roughly half the workers off with the old queen, and the swarm chooses its new home by a scouting-and-quorum process that is a genuine collective decision rather than a leader's choice. Colonies also thermoregulate the brood nest to within about half a degree, fanning to cool and clustering to warm.
Pollination role
The most important managed pollinator in world agriculture by volume, precisely because a colony can be moved, is available in enormous numbers, and will work almost any crop. That generality is also its limitation: honey bees have short tongues and cannot reach deep flowers, they will not work in cold or wet weather when bumblebees will, and they cannot buzz-pollinate at all — so tomatoes, blueberries and cranberries are served far better by others. A landscape with honey bees and nothing else is not a well-pollinated landscape.

High in aggregate because of sheer numbers and manageability, rather than high per visit. Several wild bees deposit more pollen per flower visit on the crops they specialise in.

What it forages on
Strongly flower-constant: an individual forager works one species per trip, which is exactly what makes it useful as a pollinator. It favours shallow, open flowers accessible to a short tongue and large concentrated patches over scattered ones.

Honey

Stores a harvestable surplus

A strong colony can produce well beyond its own winter requirement in a good year, and the surplus is what a beekeeper takes. The colony's own need in a temperate climate is on the order of 15-25 kg of stores to reach spring; anything above that is negotiable.

Relationship with people

How people interact with it
Kept for at least 4,500 years and probably longer — Egyptian relief carvings show organised beekeeping in the third millennium BCE, and honey hunting from wild colonies is far older still. The relationship is genuinely domestication-adjacent rather than domestication: managed honey bees remain fully capable of living wild, swarms leave and establish themselves without help, and there is no bred dependency on people of the kind cattle or wheat show.
Management
Managed at every scale from a single garden hive to migratory operations of tens of thousands of colonies moved between crops. Keeping honey bees is agriculture, not conservation — a point the pollination section takes some care over, because adding hives to a landscape adds competition for the wild bees already in it.
Conservation
Not a threatened species. Managed colony numbers globally have risen over recent decades, even as colony losses in particular regions and years have been severe. The threats that matter to honey bees are Varroa destructor and the viruses it transmits, poor forage in intensive farmland, and pesticide exposure — but conflating honey bee health with pollinator decline is the single most common error in public discussion of bees.
