Asiloidea

Asiloidea is a superfamily of flies belonging to the order Diptera. This group, often referred to as bee flies and their relatives, is characterized by a diverse range of adult morphologies and larval habitats. The superfamily is primarily composed of two major families, Bombyliidae and Asilidae, though several other smaller families are also included. Bombyliidae, the bee flies, are well-known for their stout, hairy bodies, which often mimic bees and wasps, a form of Batesian mimicry. They are typically nectar feeders and play a role in pollination. Asilidae, the robber flies, are predatory insects with a robust build and strong legs, adapted for catching other insects in flight. Their larvae are often found in soil or decaying organic matter, where they prey on other invertebrates. Other families within Asiloidea include Scenopinidae (window flies), Therevidae (stiletto flies), and Apioceridae (flower-mimicking flies), each with distinct ecological roles and life histories. The classification of Asiloidea is based on shared morphological features, particularly those of the adult insect, and has been further refined through molecular phylogenetic studies. These flies are found worldwide in a variety of habitats, from deserts to forests.
