Western Honey Bee

Apis mellifera

Also known as European Honey Bee, Honningbie

One of the world's most important managed pollinators. Through pollination, the honey bee is linked to the reproduction of many wild plants and to the production of a large share of the crops people eat — connecting nature directly to the food system.

Among the most important managed pollinators worldwide.Links wild-plant reproduction to human food production.Colony works as a single 'superorganism'.Not at risk of extinction as a managed animal — but bee health is under pressure.
Why this matters

By pollinating crops and wild plants, the honey bee supports food production — and through it, part of the human food system.

Species

Human Translation

A social insect that lives in colonies of a queen and thousands of workers. It is both a wild species and the most widely managed pollinator on Earth.

03

Conservation

IUCN Status
DDData Deficient
Population Trend
Mixed — managed colonies are widespread; wild status unclear
Wild Population
Tens of millions of managed colonies worldwide; truly wild/feral numbers are poorly known.
Main Issue
Pressures on bee health and on the pollination service — not extinction of the managed species.
Human Translation

Data Deficient means there isn't enough data on wild populations for a full assessment. As a managed animal the honey bee is not at risk of extinction — but the health of colonies and the pollination they provide are under real pressure.

04

Distribution

Native Range
Europe, Africa and western Asia.
Current Range
Now found on every continent except Antarctica, largely through managed beekeeping.
Human Translation

Originally from the Old World, honey bees are now kept almost everywhere people farm.

05

Biology

Length
Workers ~12–15 mm
Weight
About 0.1 g per bee
Lifespan
Workers weeks to months; a queen can live several years
Diet
Nectar and pollen from flowering plants
Key Food
Nectar, Pollen
Reproduction
Eusocial: a single queen lays the eggs for an entire colony; new colonies form by swarming.
Behaviour
  • Lives in large cooperative colonies
  • Communicates food locations via the 'waggle dance'
  • Forages across wide areas for nectar and pollen
  • Stores honey as a food reserve
Human Translation

A honey bee colony works as a single superorganism. While foraging for food, bees move pollen between flowers — which is the pollination other plants and crops rely on.

06

Ecological Intelligence

Ecological Role
Keystone pollinator and mutualist linking plants to reproduction.
Keystone
Widely treated as a keystone mutualist for the breadth of plants it pollinates.
Trophic Level
Primary consumer (feeds on nectar and pollen)
Human Translation

Mutualist = two species that benefit each other; bees get food while plants get pollinated. This links the honey bee to both wild plant reproduction and human food production.

Threats & Solutions

Threat → Category → Driver
Threats
Pesticides
Pollution · Pesticide Use

Some pesticides are associated with harm to bees even at sub-lethal doses.

ConfidenceHigh
Parasites & Disease
Disease · Introduced Pests & Pathogens

The Varroa mite and associated diseases are a leading cause of colony losses.

ConfidenceHigh
Forage Loss
Habitat · Intensive Agriculture

Intensive single-crop farming reduces the varied flowers bees need across the season.

ConfidenceMedium
Climate Change
Climate · Global Warming

Shifting seasons can desynchronise bees from the flowering they depend on.

ConfidenceMedium
Solutions
Pesticide Reduction

Cutting and better-targeting farm chemicals that harm pollinators.

Cutting and targeting harmful pesticides directly reduces exposure.

Pollinator Habitat

Restoring wildflowers, hedgerows and margins for pollinators to feed.

Restoring wildflowers and margins gives bees season-long forage.

Diverse Farming

Mixed crops and flowering plants instead of single-crop fields.

Mixed cropping rebuilds the varied food supply pollinators need.

Bee Health Management

Managing parasites and disease to keep colonies healthy.

Managing Varroa and disease keeps colonies viable.

Scientific Monitoring

Tracking populations so decisions are based on real data.

Tracking colony health and wild pollinators closes data gaps.

Climate Action

Cutting greenhouse-gas emissions — the only thing that addresses the root of sea-ice loss and climate pressures.

Limiting warming reduces disruption to flowering and foraging.
