Simplocaria

Simplocaria species are pill beetles, characterized by their compact, rounded body form that allows them to conglobate (roll into a ball). As members of the tribe Simplocariini, they can be distinguished from related genera within Byrrhidae by specific morphological features of the tribe, though precise diagnostic characters for the genus require examination of detailed morphological traits not specified in available sources.

Forest habitats, as documented for Simplocaria metallica in northern Alberta, Canada. The genus appears to be associated with northern forest ecosystems.

Recorded from Denmark (DK), Norway (NO), and Sweden (SE) in GBIF distribution records. Simplocaria metallica specifically documented from northern Alberta, Canada. The genus likely has a Holarctic distribution given these records.

Pill beetles in this genus exhibit conglobation behavior—rolling into a compact ball when disturbed, a defensive adaptation common to the family Byrrhidae.
