Armadillidium is a genus of the small terrestrial crustacean known as the woodlouse. Armadillidium are also commonly known as pill woodlice, leg pebbles, pill bugs, roly-poly, or potato bugs, and are often confused with pill millipedes such as Glomeris marginata. They are characterised by their ability to roll into a ball ("volvation") when disturbed.
Armadillidiidae is a family of woodlice, a terrestrial crustacean group in the order Isopoda. Unlike members of some other woodlice families, members of this family can roll into a ball, an ability they share with the outwardly similar but unrelated pill millipedes and other animals. This ability gives woodlice in this family their common names of pill bugs or roly polies. Other common names include slaters,potato bugs, butchy boys and doodle bugs. Most species are native to the Mediterranean Basin, while a few species have wider European distributions. The best-known species, Armadillidium vulgare, was introduced to New England in the early 19th century and has become widespread throughout North America.

Porcellio montanus is a species of woodlouse in the genus Porcellio belonging to the family Porcellionidae that can be found in Czech Republic, France, Italy and Switzerland. Only one subspecies have been recorded, Porcellio montanus alpivagusVerhoeff, 1928.

Porcellionides approximatus is a woodlouse that is endemic to Crimea, Ukraine.
Armadillidae is a family of woodlice, comprising around 80 genera and 700 species. It is the largest family of Oniscidea, and one of the most species-rich families of the entire Isopoda. Armadillids generally have a strongly convex body shape, with some rather shallowly convex. Like members of the woodlice family Armadillidiidae, armadillids are capable of enrolling into a sphere (conglobation), and are commonly known as pill bugs. Armadillids differ from the Armadillidiidae in that the antennae are fully enclosed within the sphere.
Scleropactidae is a family of woodlice, with a predominantly Gondwanan distribution. It contains the following genera:
Suarezia is a genus of woodlice, in the family Scleropactidae, containing the two species Suarezia differens and Suarezia heterodoxa, both of which are endemic to Madagascar.
Niambia is a genus of woodlice in the family Platyarthridae. There are at least 20 described species in Niambia.
Rhyscotus is a genus of armadillo woodlice, land crustacean isopods of the family Rhyscotidae. It was first described in 1885 by Gustav Budde-Lund.
Armadilloniscus is a genus of woodlice in the family Detonidae. There are more than 30 described species in Armadilloniscus.
