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.
Porcellionidae is a terrestrial family of the order Isopoda.
Oniscoidea is a superfamily of isopod crustaceans, which includes most of the land-living woodlice. It includes the "common woodlouse", Oniscus asellus, in the namesake family Oniscidae.
Haplophthalmus is a genus of woodlice in family Trichoniscidae. It contains 47 described species, of which two are listed as vulnerable species on the IUCN Red List – Haplophthalmus abbreviatus and Haplophthalmus rhinoceros.
Porcellio is a genus of woodlice in the family Porcellionidae. These crustaceans are found essentially worldwide. A well-known species is the common rough woodlouse, Porcellio scaber.
Soteriscus is a genus of woodlice in the family Porcellionidae found in Macaronesian islands and adjacent parts of Europe and Africa. It contains the following species:
Trichoniscidae are a family of isopods (woodlice), including the most abundant British woodlouse, Trichoniscus pusillus. Most species of woodlice that have returned to an aquatic or amphibian way of life belong to this family. Several species from the following genera live in water and on land: Titanethes, Cyphonetes, Alpioniscus, Scotoniscus, Bureschia, Brackenridgia, Mexiconiscus, Trichoniscoides, Cretoniscellus, Balearonethes and Cyphoniscellus.
Trichoniscus is a genus of woodlice. It contains over 100 species, including the common pygmy woodlouse, Trichoniscus pusillus:
Porcellionides is a genus of woodlice in the family Porcellionidae. It includes the following species :
Styloniscidae is a family of woodlice, including the following genera:
Platyarthridae is a family of woodlice, containing the following genera:
Porcellio dilatatus is a species of woodlouse in the genus Porcellio belonging to the family Porcellionidae. This species is widespread in Europe, and has also been introduced to North America from Western Europe. They are 15 millimetres (0.59 in) long, are brown coloured and striped. They can be found feeding on alder leaves, but mostly feeds on organic food substrates, such as lettuce in the wild. It also feeds on inorganic metal salts.
Trachelipus is a genus of woodlice in the family Trachelipodidae, containing the following species:
Porcellio zarcoi is a species of woodlouse in the Porcellionidae family that is endemic to Madeira.
Metatrichoniscoides nemausiensis is a species of woodlouse in the family Trichoniscidae that is found in France.
Metatrichoniscoides fouresi is a species of woodlouse in the family Trichoniscidae that is found in France.
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:
Huntonia is a monotypic genus of isopods belonging to the family Philosciidae. The only species is Huntonia montana.
Laureola is a genus of woodlice, a land crustacean isopod of the family Armadillidae.
