Honey Bee (Apis mellifera) – Identification, Life Cycle, Behaviour and Swarm Management

The Honey Bee (Apis mellifera) is one of the most recognisable and ecologically important insects found throughout the United Kingdom. Known for producing honey, constructing wax combs and pollinating flowering plants, honey bees contribute significantly to natural ecosystems and agricultural production. Although they are beneficial insects, their presence can occasionally become a concern when large colonies establish themselves inside buildings or other structures.

Adult worker honey bees typically measure between 12 and 15 mm long. They have brown-and-black banded bodies covered in fine hairs, two pairs of wings and specialised structures for collecting nectar and pollen. Honey bees are social insects that live in organised colonies containing a queen, thousands of female workers and male drones. Their complex behaviour includes communication through pheromones and the distinctive waggle dance.

During spring and early summer, established colonies may reproduce through swarming. This involves a queen leaving with thousands of workers to find a new nesting location. Swarms may temporarily settle on trees, fences or buildings before moving elsewhere. Occasionally, bees establish permanent colonies within roof spaces, chimneys or wall cavities.

Because honey bees are valuable pollinators, responsible management prioritises identification, assessment and relocation where practical. Understanding their biology, nesting habits and behaviour helps property owners distinguish honey bees from wasps and other insects and choose an appropriate response.

Honey Bee – Quick Facts

Honey Bee Taxonomy and Classification

The Honey Bee belongs to the family Apidae, which also includes bumblebees and several other groups of bees. It is a member of the genus Apis, whose species are characterised by highly organised social colonies and the production of wax combs.

The western honey bee has numerous recognised subspecies. The dark European honey bee (Apis mellifera mellifera) has a long history in Britain, while imported subspecies and subsequent breeding have contributed to the genetic diversity of modern managed colonies.

How to Identify a Honey Bee

Honey bees have several physical characteristics that distinguish them from wasps, bumblebees and other flying insects.

Brown and Black Banded Abdomen

Worker honey bees commonly have brown, golden-brown and dark abdominal bands. Colour varies between individuals and genetic lineages.

Fine Body Hairs

The head, thorax and abdomen are covered with fine hairs that assist in collecting pollen from flowers.

Two Pairs of Wings

Honey bees possess four wings, with the smaller hind wings linked to the forewings during flight.

Six Legs

Like all insects, honey bees have three pairs of legs attached to the thorax.

Pollen Baskets

Female workers possess specialised structures called corbiculae on their hind legs, allowing them to transport collected pollen.

Specialised Mouthparts

A proboscis allows bees to collect nectar, while their mandibles are used for manipulating wax and other materials.

Moderately Robust Body

Honey bees have a compact body shape, although they are generally slimmer and less densely hairy than bumblebees.

Honey Bee vs Wasp vs Bumblebee

Correct identification is particularly important when insects are repeatedly entering a building or gathering around a property.

Honey bees usually appear browner and hairier than common wasps, while bumblebees are typically larger-bodied and more densely covered in hair.

Physical Adaptations of Honey Bees

Honey bees possess specialised features that support efficient foraging, communication, nest construction and colony defence.

Branched Body Hairs

Fine, branched hairs trap pollen grains as bees move between flowers.

Electrostatic Pollen Collection

Electrical charges associated with bees and flowers help pollen adhere to the body during foraging.

Proboscis for Nectar Collection

The elongated mouthparts allow workers to collect nectar from flowering plants.

Pollen Baskets

Workers pack pollen onto specialised areas of their hind legs before returning to the colony.

Wax-Producing Glands

Worker bees possess abdominal glands that produce wax scales used to build honeycomb.

Defensive Sting

Female honey bees possess stings. The barbed sting of a worker can become lodged in mammalian skin, often causing fatal injury to the bee when it pulls away.

Honey Bee Colony Structure

Honey bees live in highly organised colonies in which individuals perform different roles.

The Queen

A typical colony contains one reproductive queen. Her principal role is laying eggs, while her pheromones also influence colony organisation and behaviour.

Queens are usually larger than workers and have elongated abdomens adapted for egg production.

Worker Bees

Workers are female bees responsible for most daily colony activities.

Their tasks include:

• Collecting nectar and pollen
• Feeding developing larvae
• Cleaning and maintaining the hive
• Producing wax and building honeycomb
• Regulating nest temperature
• Guarding the colony entrance
• Collecting water

Drone Bees

Drones are male honey bees whose principal reproductive function is mating with virgin queens.

They have broader bodies and noticeably larger eyes than workers.

Honey Bee Colony Size

Actual colony size varies with climate, food availability, genetics, queen performance and colony health.

Honey Bee Life Cycle and Reproduction

Honey bees undergo complete metamorphosis, developing through four stages: egg, larva, pupa and adult.

1. Egg Stage

The queen lays eggs individually within wax cells.

Fertilised eggs normally develop into female workers or queens, while unfertilised eggs develop into male drones.

Eggs generally hatch after approximately three days.

2. Larval Stage

Newly hatched larvae are fed by worker bees.

Nutrition plays an important role in determining whether a fertilised female larva develops into a worker or queen.

Future queens receive specialised feeding associated with queen development.

3. Pupal Stage

Developing bees undergo metamorphosis within capped brood cells.

During this stage, adult body structures develop.

4. Adult Stage

Fully developed bees emerge from their cells and begin performing their roles within the colony.

Honey Bee Development Times

Development times are approximate and can vary with colony conditions.

How Do Honey Bees Reproduce?

Honey bees reproduce at both the individual and colony levels.

The queen produces eggs that develop into new bees. At the colony level, reproduction occurs through swarming, when part of an established colony leaves to create a new one.

New queens typically mate during aerial mating flights with drones from surrounding colonies.

After mating, a queen may establish herself in a new colony or replace an existing queen.

What Is Honey Bee Swarming?

Swarming is a natural process through which a honey bee colony divides.

A queen leaves the original hive accompanied by a substantial number of workers.

The swarm may temporarily settle on a tree branch, fence, wall or other structure while scout bees investigate potential nesting locations.

Once a suitable site is selected, the swarm may move into a cavity where it begins constructing comb.

Swarming commonly occurs during spring and early summer in the United Kingdom.

The British Beekeepers’ Association provides guidance on recognising honey bee swarms and understanding their behaviour.

What Does a Honey Bee Swarm Look Like?

A honey bee swarm may appear as a large, dense cluster containing thousands of bees.

Common temporary resting locations include:

• Tree branches
• Garden fences
• External walls
• Hedges
• Sheds and outbuildings
• Other sheltered outdoor surfaces

Swarming bees are generally focused on finding a new nesting location rather than defending an established nest.

However, they can still sting if disturbed or threatened.

What Should You Do If You Find a Honey Bee Swarm?

If a swarm settles on your property, keep children and pets away and avoid disturbing the bees.

Do not spray the swarm with insecticides, water or other substances.

Where possible, take a photograph from a safe distance to help with identification.

The British Beekeepers’ Association swarm collector directory can help locate a volunteer beekeeper who may be able to collect and rehome an accessible honey bee swarm.

Established colonies inside buildings require a different approach from temporary outdoor swarms.

Where Do Honey Bees Build Their Nests?

Honey bees naturally favour sheltered cavities with sufficient space for comb construction and colony development.

Tree Cavities

Hollow trees provide natural nesting locations for wild-living honey bee colonies.

Wall Cavities

Bees may enter openings in external masonry and establish colonies within suitable voids.

Roof Spaces

Accessible roof voids may provide sheltered locations for colony development.

Chimneys

Disused or accessible chimneys can occasionally become occupied by honey bees.

Outbuildings

Sheds, garages and other structures may contain cavities suitable for nesting.

Managed Hives

Beekeepers provide purpose-built hives where colonies can be maintained and inspected.

Common Signs of Honey Bee Activity

Honey bee activity is often noticeable before a nest or colony becomes visible.

• Repeated flight paths: Bees travelling consistently to and from one location.
• Bees entering a building: Regular movement through gaps in brickwork, roof edges or other openings.
• Large clusters: Thousands of bees gathering temporarily during swarming.
• Wax or honey: Evidence of comb or stored honey around an established colony.
• Buzzing sounds: Persistent activity within an occupied cavity.
• Concentrated foraging: Numerous bees visiting flowering plants or collecting water.

Bees visiting flowers do not necessarily indicate that a colony is nesting nearby.

Honey Bees Nesting in Walls and Roof Spaces

Honey bees can occasionally establish colonies within structural cavities.

Unlike seasonal wasp nests, established honey bee colonies may survive from one year to the next if conditions remain suitable.

Over time, workers can construct substantial wax combs containing brood, honey and pollen.

When colonies occupy buildings, management may require specialist access, careful removal of bees and comb, and appropriate repairs.

Simply sealing the entrance while bees remain inside is not recommended.

Can Honey Bees Damage Property?

Honey bees do not normally chew through sound building materials in the way some other pests can damage structures.

However, an established colony may create problems through the accumulation of honey, wax and nesting material within a cavity.

If a colony dies or is removed without addressing the comb, remaining honey may leak or attract other insects.

Appropriate assessment is important where bees have occupied a building for an extended period.

The British Beekeepers’ Association guidance on bees in buildings explains why established colonies require specialist removal rather than ordinary swarm collection.

What Do Honey Bees Eat?

Honey bees obtain their main nutritional resources from flowering plants.

Nectar

Nectar provides sugars used as an energy source. Bees can process and store concentrated nectar as honey.

Pollen

Pollen supplies protein, fats and other nutrients required for growth and brood development.

Water

Workers collect water for colony needs, including cooling and food processing.

The availability of suitable flowering plants influences colony health, brood production and foraging activity.

How Do Honey Bees Make Honey?

Worker bees collect nectar from flowers and transport it to the colony.

Within the hive, the nectar is processed through enzymatic activity and moisture reduction.

Bees deposit the developing honey into wax cells and help evaporate excess water through ventilation.

Once sufficiently concentrated, stored honey may be sealed with wax.

Honey provides an important energy reserve, particularly when outdoor nectar sources are limited.

How Do Honey Bees Communicate?

Honey bees communicate using chemical signals, touch and specialised movements.

Pheromones

Chemical signals influence colony organisation, alarm responses, reproduction and other behaviours.

Waggle Dance

Foragers perform a directional dance that communicates information about the location of useful food sources.

Alarm Signals

Disturbed bees may release alarm pheromones that influence the defensive behaviour of nearby workers.

These communication systems allow large colonies to coordinate activities efficiently.

When Are Honey Bees Most Active?

Honey bees are primarily active during daylight hours.

Foraging generally increases during suitable warm, dry conditions when flowers provide nectar and pollen.

Spring and summer are particularly important periods for colony growth and food collection in Britain.

Activity can decline during cold, wet or windy weather.

How Do Honey Bees Survive Winter?

Honey bee colonies can survive the winter as a social group rather than relying solely on newly produced queens.

Workers form a cluster around the queen and generate heat through muscular activity.

The colony consumes stored honey to obtain the energy needed to maintain suitable temperatures.

Bees may leave the hive briefly during milder winter weather.

Why Are Honey Bees Important Pollinators?

Honey bees transfer pollen between flowers while collecting nectar and pollen.

This process supports reproduction in many flowering plants and contributes to the production of various agricultural crops.

Managed honey bee colonies can be particularly important for crop pollination where large numbers of foragers are needed.

However, honey bees are only one part of the UK’s pollinator community. Bumblebees, solitary bees, hoverflies, butterflies and other insects also provide essential pollination services.

Honey Bees and Biodiversity

Honey bees contribute to the pollination of wild plants and cultivated crops.

Their ecological relationships include interactions with flowering plants, predators, parasites and competing pollinators.

Supporting diverse habitats and flowering plants can benefit a wider range of pollinating insects.

Responsible honey bee management should consider both managed colonies and native wild pollinators.

Natural Predators and Threats to Honey Bees

Honey bees face several natural and environmental threats.

Predatory Wasps and Hornets

Some wasps and hornets prey on bees or attempt to obtain resources from colonies.

Birds

Certain birds may capture bees during flight.

Spiders

Flower-visiting bees may occasionally be caught by spiders.

Mammals

Some mammals may disturb colonies to obtain honey, brood or other food.

Varroa Mites

The parasitic mite Varroa destructor is a major concern for managed honey bee colonies.

Varroa mites feed on honey bee fat body tissue and can transmit harmful viruses.

Environmental Pressures

Food shortages, unsuitable pesticide exposure and adverse environmental conditions can affect colony health.

Do Honey Bees Sting?

Yes. Female honey bees possess stings used primarily for defence.

Workers may sting when they perceive a threat to themselves or their colony.

Unlike many wasps, a worker honey bee often cannot withdraw its barbed sting from mammalian skin without sustaining fatal injury.

Honey bees are generally more likely to defend an established colony than to sting while calmly foraging on flowers.

What Happens After a Honey Bee Sting?

A honey bee sting commonly causes immediate pain, redness and local swelling.

Some people experience a larger local reaction.

In individuals with a severe allergy to bee venom, a sting can cause anaphylaxis, which is a medical emergency.

Symptoms such as breathing difficulty, throat or tongue swelling, faintness or collapse require immediate emergency assistance. Call 999 in the UK.

For further advice, consult the NHS guidance on insect bites and stings.

What Should You Do After a Honey Bee Sting?

If a sting remains in the skin, remove it promptly without squeezing the venom sac.

Wash the area with soap and water and apply a cold compress to help reduce discomfort.

Seek appropriate medical or pharmacy advice if symptoms are severe, worsening or unusual.

If there are signs of anaphylaxis, call 999 immediately and use a prescribed adrenaline auto-injector if available, following its instructions.

Are Honey Bees Dangerous?

Honey bees are generally not aggressive when foraging undisturbed.

However, an established colony may defend its nesting area if threatened.

Sting risks can become more significant when colonies occupy busy entrances, enclosed spaces or locations frequently used by children and pets.

People with known severe bee venom allergies should take particular care around suspected colonies.

Are Honey Bees Protected by Law in the UK?

Honey bees are not subject to a blanket legal prohibition on control simply because they are honey bees.

However, pesticide use, environmental protection and the handling of colonies are subject to relevant legal and professional requirements.

Because honey bees are valuable pollinators, unnecessary destruction should be avoided and relocation considered wherever reasonably practical.

Any control decision should be based on accurate identification, the actual risk and the suitability of available management options.

Can Honey Bees Be Relocated?

Yes. Honey bee swarms and some established colonies can be relocated by appropriately experienced individuals.

Temporary outdoor swarms may be collected by volunteer beekeepers.

Established colonies inside walls, chimneys or roof voids can be considerably more difficult to remove.

Specialist removal may involve exposing the colony, transferring bees and comb, and reinstating affected building materials.

Relocation feasibility depends on access, safety and the colony’s location.

Why Should Honey Bee Colonies Not Be Sprayed Without Assessment?

Unnecessary insecticide use can kill beneficial pollinators and create additional environmental concerns.

Treating bees inside a building without a suitable plan can also leave honey and wax behind.

Remaining materials may attract other insects or create problems within the structure.

Professional assessment should consider whether the colony can be left safely in place or removed and relocated.

The British Pest Control Association’s bee management guidance discusses identification and responsible control options.

What Should You Do If Honey Bees Enter Your Property?

If bees are repeatedly entering a roof, chimney or wall cavity, avoid blocking their entrance.

Observe their activity from a safe distance and note where they are entering.

Do not attempt to dismantle building materials or remove an established colony yourself.

A specialist assessment can help establish whether the bees are temporarily investigating a cavity or have formed a permanent colony.

How to Reduce Unwanted Honey Bee Nesting

Prevention should focus on sensible property maintenance without disturbing active colonies.

• Inspect accessible exterior gaps during routine building maintenance.
• Repair damaged masonry and suitable structural openings when unoccupied.
• Maintain appropriate chimney guards and building ventilation protection.
• Investigate repeated bee entry before attempting repairs.
• Avoid blocking openings that are already being used by an active colony.
• Seek specialist advice when bees have established themselves within structural cavities.

Not every opening should be sealed, as buildings require suitable ventilation and other wildlife may also use structural spaces.

Honey Bees Around Commercial Properties

Honey bee colonies can occasionally create concerns around commercial buildings, schools, hospitality premises and other busy environments.

Potential issues include concentrated bee activity near entrances, access routes or occupied outdoor areas.

Any response should consider public safety, building access and the ecological importance of the colony.

Correct identification and appropriate specialist advice are important before intervention.
