Overview
Honey bees are social, flying insects in the order Hymenoptera belonging to the genus Apis. They are one group among the many types of bee species and are distinguished by their production and storage of honey, construction of perennial colonial nests from secreted wax, and an advanced eusocial organisation. The study of bees, including honey bees, forms part of melittology; beekeeping or apiculture manages honey bee colonies for pollination and hive products.
Taxonomy and diversity
All true honey bees are members of the tribe Apini, contained within the single genus Apis. Modern treatments commonly recognize about seven living species and multiple regional subspecies, though historical classifications have varied. Only members of Apis are usually called honey bees, while other social bees such as bumblebees and stingless bees display similar but distinct social systems.
Colony structure and life cycle
A typical honey bee colony contains three castes: a single reproductive queen, thousands of non-reproductive female workers and seasonal male drones. Honey bees exhibit haplodiploid sex determination: fertilized eggs become females, and unfertilized eggs develop into males. Castes perform different duties at different ages; workers move from brood care to nest maintenance and later forage outside the nest. Queens may live for several years under favourable conditions, while workers typically live for weeks to months and drones die after mating or are expelled before winter.
Communication and navigation
Foragers communicate resource locations using a symbolic locomotor signal known as the waggle dance and rely on visual and olfactory cues to navigate. Scent plays a central role throughout colony life: glandular secretions act as social signals. For example, the Nasonov gland produces a characteristic pheromone that helps gather workers, orient nestmates and attract bees to a settled swarm.
Nesting, comb and honey production
Apis species build wax combs of regular hexagonal cells used for brood rearing and honey storage. Different species show contrasting nesting habits: some are cavity-nesters that occupy hollow trees or man-made hives, others are open-nesting and form exposed single-comb colonies. Worker bees secrete wax from abdominal glands, process nectar through enzymatic activity and dehydrate it to produce honey, which serves as an energy reserve for the colony.
Origins and fossil record
Fossils indicate Apis-like bees were present in Eurasia by the transition between the Eocene and Oligocene epochs. The early record suggests a long evolutionary history in Old World regions; the sparse fossil record in South Asia complicates precise reconstructions. No Apis species was native to the pre-Columbian New World, and only a single mid-Miocene specimen from Nevada has been identified as Apis-like in North America. The fossil and genetic evidence together point to diversification in Eurasia and Asia.
Ecological and human importance
Honey bees are key pollinators for many wild plants and cultivated crops; their pollination services underpin fruit, vegetable and oilseed production in many regions. Humans also harvest hive products such as honey, beeswax and propolis, and practise apiculture for both livelihoods and scientific study. Typical human uses include:
- Managed pollination of agricultural crops
- Production of honey and wax-based products
- Research in behaviour, genetics and ecology within melittology
Threats and conservation
Honey bee populations face multiple stresses: parasites and pathogens (notably the Varroa mite), habitat loss, pesticide exposure and nutritional deficits. Regions have reported elevated overwintering losses and episodic declines; causes are often multifactorial and remain an active area of research. Conservation and management combine habitat protection, disease control, integrated pest management and responsible apiculture to support healthy colonies.
Further reading and resources
For introductory information consult specialist literature and resources on bee biology and beekeeping. General summaries and taxonomic details are available through reputable entomological sources and regional apiculture guides. For technical and historical aspects see entries on the genus Apis, the tribe Apini, and studies of the fossil record.
Key topics to explore further include caste determination and haplodiploidy, the waggle dance and navigation, chemical ecology of pheromones, species-level diversity across Asia and Africa, and the role of beekeeping in modern agriculture. Reliable overviews discuss the fossil context from the Eocene to the Oligocene, regional species lists and recognized species and subspecies, and comparisons with other social bees such as bumblebees.
Practical beekeeping and conservation measures are informed by ecological research and local agricultural needs; interested readers should consult regional extension services and apicultural associations for applied guidance.
