Prionyx is a genus of wasps in the Sphecidae family. They're known to hunt and feed on grasshoppers.
Wasps of the genus Sphex (commonly known as digger wasps) are cosmopolitan predators that sting and paralyze prey insects. Sphex is one of many genera in the old digger wasp family Sphecidae (sensu lato), though most apart from the Sphecinae have now been moved to the family Crabronidae. There are over 130 known Sphex species.
