Crabronidae is a large family of wasps within the superfamily Apoidea.
This family has historically been treated as a subfamily in the now-defunct Spheciformes group under the family Sphecidae. The Spheciformes included well over 200 genera, containing well over 9000 species. Revision of these taxa resulted in the restriction of the Sphecidae to what was once the subfamily Sphecinae. As a result, the former Crabroninae was elevated to family status as Crabronidae. Subsequent revision has further restricted the Crabronidae. Several of the subfamilies of the Crabronidae are often treated as families in their own right, as is true of the most recent phylogenies. Of these lineages of Apoidea, only three were not included within Crabronidae in the past: Ampulicidae, Sphecidae, and Anthophila.
