bombyliids

Bombyliidae is a large family of flies commonly known as bee flies or bombyliid flies. These insects are characterized by their stout, often hairy bodies and long, slender proboscis, which they use to feed on nectar. Their appearance can be quite diverse, with many species mimicking bees and wasps in coloration and shape, a form of mimicry that helps protect them from predators.

The larvae of bombyliid flies are typically parasitic or predatory, often developing in the egg masses or nests of other insects, such as grasshoppers, solitary bees, and wasps. This parasitic lifestyle plays a significant role in regulating populations of their host species. Adult bombyliids are important pollinators, visiting a wide variety of flowers to collect nectar, and in the process, transferring pollen.

Bombyliid flies are found worldwide, with the greatest diversity in arid and semi-arid regions. They are often observed hovering in sunny areas, darting rapidly from flower to flower. Their flight can be very agile, allowing them to maneuver effectively to collect food and avoid threats. The family Bombyliidae is divided into numerous subfamilies and genera, reflecting the extensive evolutionary diversification of this group.
