Convergent Weevil Wasp
Cerceris convergens is a fascinating solitary hunting wasp commonly found in arid western landscapes, including the Mojave Desert. Female wasps dig intricate burrows in sandy or loose soil, immobilizing snout beetles and weevils with precise stingers to provide fresh food for their developing larvae.
Life Cycle: Females excavate subterranean tunnels in well-drained soils, provisions individual cell chambers with paralyzed weevils, lays a single egg per cell, and seals the nest. Larvae feed on the paralyzed beetles before spinning cocoons to overwinter and pupate.
Size 0.35 to 0.55 in (0.9 to 1.4 cm)
Sexual Dimorphism: Females feature specialized clypeal structures and modified mandibles for digging and prey transport, while males are slightly smaller with distinct yellow facial markings and prominent antenna segments.
Metamorphosis: complete (egg, larva, pupa, adult)
Cerceris convergens is a solitary crabronid wasp uniquely adapted to the arid washes and sandy soils of the southwestern deserts. Found at elevations ranging from 1,100 ft (335 m) to 6,800 ft (2,072 m), female convergent weevil wasps build underground nests where they store paralyzed weevils to sustain their offspring.
