In Minnesota, there is one described species within the genus Paranthidium—Paranthidium jugatorium.  This species nests in pre-existing cavities belowground such as empty ground nests of other bees or burrows of other insects. To help form the nest structure, females collect plant resins to bind together soil particles, particularly in sandy soils. 

​

Paranthidium jugatorium has a broad robust form, dark eyes, shaded wings, and a black integument with yellow markings on the head, thorax, and abdomen. This genus/species has an arolium (pad) between the tarsal claws, one characteristic to differentiate it from bees in the genus Anthidium. The forewing has two submarginal cells, and the second recurrent vein extends considerably beyond the second submarginal cell. The yellow bands on the abdomen are interrupted in the middle and occur in the middle of the tergites. Females collect pollen on hairs on the underside of their abdomen and are specialists (oligoleges) of late summer-blooming plants in the family Asteraceae such as Helianthus, Rudbeckia, and Heliopsis. Paranthidium jugatorium ranges in length from 6 to 11 mm (0.24 to 0.43 inches).
