A subspecies of potter wasp in the genus Zethus, distinguished by variegated coloration. As a member of the Eumeninae subfamily, it constructs mud or clay nests provisioned with paralyzed prey for its larvae. The subspecies designation indicates geographic variation in color pattern within the broader Zethus spinipes species complex.
Zopherus granicollis ventriosus
Zopherus granicollis ventriosus is a subspecies of ironclad beetle in the family Zopheridae. Like other members of the genus, it possesses an exceptionally hard, heavily sclerotized exoskeleton that makes specimens notoriously difficult to pin for museum collections.
