Cerceris clypeata
weevil wasp
Cerceris clypeata is a solitary weevil wasp in the family Crabronidae, found in North America. Males exhibit probable marking behavior on grass stems and vegetation using cephalic gland secretions, a trait rarely recorded in this genus but common in the subfamily Philanthinae. The species is closely related to other Cerceris wasps that specialize on particular prey groups, though specific prey associations for C. clypeata remain undocumented.
