Bumblebee

Bumblebees are large, fuzzy bees in the genus Bombus, found mainly in temperate regions of the Northern Hemisphere.

Bumblebees are large, fuzzy bees in the genus Bombus, found mainly in temperate regions of the Northern Hemisphere. They are important pollinators of wild plants and crops, and many species are in decline because of habitat loss, pesticides, disease, and climate change. In Canada, bumblebees are important pollinators in agricultural regions and natural habitats, and some Canadian species have experienced population declines.

Taxonomy and appearance

Bumblebees belong to the genus Bombus in the bee family Apidae, order Hymenoptera. They are typically robust, hairy insects with rounded bodies and bold colour patterns, though species vary in size and markings. They are distinguished by their fuzzy bodies, black-and-yellow coloration, and loud buzzing flight. There are more than 250 species.

Habitat and distribution

Bumblebees are found mainly in temperate climates of the Northern Hemisphere, with some species also present in other regions. They are well adapted to cooler conditions and can forage at lower temperatures than many other bees. Their habitat includes temperate regions, especially the Northern Hemisphere.

Behaviour and life cycle

Bumblebees are social insects that live in colonies. Bumblebee colonies usually include a queen, workers, and males. Colony members feed on nectar and pollen, and the lifespan of workers is short, often measured in weeks. Unlike honeybees, bumblebees do not produce honey in large storeable amounts.

Ecological importance

Bumblebees are major pollinators of wild flowers and many crops. Their ability to buzz pollinate makes them especially valuable for plants that require vibration to release pollen. They are important pollinators for wild plants and agricultural crops such as tomatoes, blueberries, and squash.

Conservation

Many bumblebee species are facing population decline. Commonly reported pressures include habitat loss, pesticide use, disease, and climate change. Some species are declining in Europe, North America, and Asia. Conservation status varies by species; many are threatened or declining.
