19 (see text) Pemphredonidae is a family of aphid wasps formerly treated as the subfamily Pemphredoninae.

[5] As with all other apoid wasps, the larvae are carnivorous; females hunt for prey on which to lay their eggs, mass provisioning the nest cells with paralyzed, living prey that the larvae feed upon after hatching from the egg.

[citation needed] As Pemphredoninae, this taxon was previously divided into four tribes: Entomosericini, Odontosphecini, Psenini, and Pemphredonini.

Phylogenetic analyses to resolve the paraphyly of Crabronidae through erecting additional families also found the Pemphredoninae to be polyphyletic.

[1] Two fossil wasp genera from the Weald Clay were originally considered to possibly be in the Pemphredoninae.
