Bee flies are a family of true flies in the family Bombyliidae, named for their bee-like appearance. Adults typically feed on nectar and many species are pollinators, while the larvae of many species are parasitoids or predators of other insects. They are common on flowers and are found in a wide range of habitats worldwide.

Description

Bee flies are usually robust, hairy flies that resemble bees or bumblebees. Their long mouthparts are adapted for sipping nectar while hovering. Many species have stout, hairy bodies and a long proboscis for feeding on nectar, and adults often hover near flowers.

Life cycle and ecology

Adults feed mainly on nectar, while larvae often live as parasitoids or predators of the eggs, larvae, or pupae of other insects. Larvae of many species develop as parasitoids of bees, wasps, or other insects, making the family ecologically important in insect food webs.

Distribution and habitat

Bee flies occur worldwide, with many species in warm, dry regions and many tropical species. They are especially diverse in arid and tropical regions, but some species occur in temperate areas. In Canada, about 130 species are found, and they are often seen around sunny grassy areas and flowers, especially in spring.

Relationship with people

Bee flies are harmless to people and do not sting. Some species are valued as pollinators and are also noted for their bee-mimicking appearance.
