Ancistrocerus tuberculocephalus - female
The Western counterpart of the well-known A. campestris. Californian individuals have much reduced red color compared with most of those originating from the Four Corner States, a phenomenon also occurring e.g. in Polistes aurifer.
Mason Wasps sometimes take body fluids from some of the larvae they capture, severely chewing body parts in the process. Whether these damaged preys later can also serve as food for the brood is poorly known.
