Prionyx fervens
Prionyx fervens is a solitary thread-waisted wasp in the family Sphecidae. It is a ground-nesting predator that hunts grasshoppers, paralyzes them, and provisions its burrow with living prey for larval development. The species ranges from Argentina to the southern United States, with documented nesting behavior observed in coastal southeastern Brazil.
Prionyx thomae
Prionyx thomae is a solitary, thread-waisted wasp in the family Sphecidae. It is one of seven Prionyx species in the United States, ranging from the southeastern and western U.S. south to Argentina. The species is a specialist predator of grasshoppers, paralyzing them with venom to provision underground nests for its larvae. It lacks a common English name, reflecting its limited economic importance.
