Parancistrocerus leionotus
potter wasp, mason wasp
Parancistrocerus leionotus is a species of potter wasp in the subfamily Eumeninae. Unlike most related species in its genus, it has been documented using small cavities in rocks or concrete as nest sites rather than the more typical hollow twigs or plant stems. The species was described by Viereck in 1906 and is recognized as a valid taxon in major biological databases.
