Brief Summary
provided by Catalog of Hymenoptera in America North of Mexico
Subgenera have frequently been recognized in this large genus, but Bohart and Menke believe that on morphological grounds it is preferable to recognize only species groups. This concept is substantiated by a consideration of the ethology, for clearcut differences have not been demonstrated for the several species groups. These wasps nest in the soil, usually constructing multicellular nests, some nesting gregariously, others are solitary. The prey consists of Diptera and, frequently, each species has preferences for flies belonging to one or another suborder or section.
