Asilidae, Assassin Robber Fly

Habitat and ecology
The Causse du Larzac is a limestone karst plateau, a habitat typical of those favoured by many species of Asilidae
Asilidae generally occur in habitats that are open, sunny and dry or even arid. They favour open or scattered vegetation, and some species even frequent bare ground. Typical habitats include savannah, forest steppe, open steppe, semi-desert, maquis shrubland, and related shrubland types such as fynbos and chaparral. Their biodiversity is lower in forested ecosystems and, where Asilidae do occur in such environments, they tend to concentrate in the glades and margins. In those conditions the interrupted canopy leaves space for various species of shrubs and herbaceous plants suited to Asilid styles of predation.
