This species of wasp preys exclusively on acorn weevils. The females dig nests in the ground where they create cells and lay a fertilized egg. Next, the female wasp goes off in search of a weevil. She stings and paralyzes her prey, and then the weevil is brought back to the nest and stuffed inside the cell where they will remain paralyzed until the wasp larva hatches. Immediately after hatching, the larva feeds on the alive, yet paralyzed weevil. Eventually, the wasp larva pupates, after which the adult form will leave the nest.
