Apioceridae

Apioceridae, commonly known as bloom flies or flower-loving flies, is a small family of flies in the order Diptera. They are characterized by their relatively large, robust bodies and their habit of visiting flowers, where they feed on nectar. The family is found primarily in arid and semi-arid regions of North and South America, with a few species extending into Australia. There are currently around 120 described species within the Apioceridae family.

The adult bloom flies are typically medium to large-sized flies, with a stout build and often brightly colored bodies, although some species are more somber in appearance. Their antennae are short and aristate. The larvae of Apioceridae are predaceous and are thought to develop in the soil, feeding on insect larvae and other soil-dwelling invertebrates. The life cycle and larval development of most species remain poorly understood due to their subterranean habits.

Apioceridae are often observed basking on the ground or on vegetation, and their flight is usually direct and strong. Their association with flowers is a key characteristic, hence their common name. While they are not considered economically significant, their role in pollination and as predators in their ecosystems is of ecological interest. Research on this family continues to expand our knowledge of their distribution, behavior, and evolutionary relationships.
