Hyloniscus riparius is a species of woodlouse found in Central and Eastern Europe and subsequently introduced to North America. It is strongly associated with flood plains and can tolerate periods of up to eight weeks submerged under water. [3] In North America, it was first found at St. John's, Newfoundland in 1951, and later in New York, New Jersey, Pennsylvania and North Carolina. [4]
Armadillidium vulgare, the common pill-bug, potato bug, common pill woodlouse, roly-poly, slater, doodle bug, or carpenter, is a widespread European species of woodlouse. It is the most extensively investigated terrestrial isopod species.
Porcellionidae is a terrestrial family of the order Isopoda.
Porcellio laevis is a species of woodlouse in the genus Porcellio. As the species epithet laevis as well as the vernacular name "swift woodlouse" suggests, the species is capable of quick bursts of speed when provoked.
Trichorhina mulaiki is a species of woodlouse in the family Platyarthridae.
Eleoniscus is a genus of the small terrestrial crustaceans known as woodlice. It includes one species, Eleoniscus helenae, which is endemic to Alicante province, Spain, where it is known from two caves. It may have been extirpated from one of the two caves through the increasing urbanisation of the Macizo de Montgó.
Trichoniscidae are a family of isopods (woodlice), including the most abundant British woodlouse, Trichoniscus pusillus.
A woodlouse is a crustacean from the monophyletic suborder Oniscidea within the isopods. They get their name from often being found in old wood.
Trichoniscus pusillus, sometimes called the common pygmy woodlouse, is one of the five most common species of woodlice in the British Isles. It is acknowledged to be the most abundant terrestrial isopod in Britain. It is found commonly across Europe north of the Alps, and has been introduced to Madeira, the Azores and North America.
Ligiidae is a family of woodlice, the only family in the infraorder Diplocheta. Its members are common on rocky shores, in similar habitats to those inhabited by species of the bristletail Petrobius and the crab Cyclograpsus. The family contains these genera:
Androniscus dentiger, the rosy woodlouse or pink woodlouse is a species of woodlouse found from the British Isles to North Africa.
Armadillidium pictum is a species of woodlouse which occurs over most of Europe, except the Mediterranean Basin and Southeast Europe. In the British Isles, it is only known from a few sites, making it by some accounts, "Britain's rarest woodlouse". Since these sites are all remote from human habitation, in Cumbria and Powys, the species is thought to be native rather than introduced.
Hemilepistus is a genus of woodlice, created by G. H. A. Budde-Lund in 1879 as a subgenus of Porcellio, but raised to the rank of genus by Karl Wilhelm Verhoeff in 1930. It contains the following species:
Agnaridae is a family of woodlice. They were formerly considered part of the Trachelipodidae, but were moved from that family to Porcellionidae in 1989, and then placed as a separate family in 2003.
Platyarthrus hoffmannseggi is a species of woodlouse which is closely associated with ants' nests, particularly those of Lasius flavus, Lasius niger and species of Myrmica, where it feeds on ant droppings or mildew. It is white, 4 millimetres (0.16 in) long, and has a distinctive oval shape and short antennae. Its distribution appears to follow those of the ants with which it lives, and the British Isles are the north-westerly limit of its range. Elsewhere, P. hoffmannseggii extends south to the Mediterranean Sea. It is found outside Europe in North Africa and Turkey, and has been introduced to Australia and North America.
Trachelipus rathkii, also known as Rathke's Woodlouse, is a species of woodlouse in the genus Trachelipus. It can be found across Europe, except in the Mediterranean Basin. It has also been introduced to North America, where it can be found across most of the northern half of the United States and southern Canada.
Armadillidium klugii is a lesser-known, rare Balkan, Dalmatia-based species of woodlouse, most distinguished by its colouration which resembles the red markings of the Mediterranean black widow Latrodectus tredecimguttatus. This is probably a kind of mimicry, to ward off predators that mistake the harmless animal for a venomous spider.
Armadillidium nasatum is a large, Western European-based species of woodlouse that has been introduced to North America, along with Armadillidium vulgare also found in other parts of Europe.
Helleria brevicornis, the sole species of the monotypic genus Helleria, is a terrestrial woodlouse endemic to the islands and coastal regions of the northern Tyrrhenian sea. H. brevicornis is of interest due to its endemism, unique ecology and basal position in the suborder Oniscidea.
Invertebrate iridescent virus 31 (IIV-31), also known informally as isopod iridovirus, is a species of invertebrate iridescent virus in the genus Iridovirus. Oniscidea serve as hosts. Infection is associated with decreased responsiveness in the host, increased mortality, and most strikingly, the emergence of an iridescent blue or bluish-purple colour due to the reflection of light off a paracrystalline arrangement of virions within the tissues.
Hawaiioscia is a genus of woodlouse known from the Hawaii, Rapa Nui, and Costa Rica. The genus was originally described from Hawaii on the presence of four troglobitic species on separate islands. A species within this genus was then described from Rapa Nui which lacked troglobtic traits, but only persists in cave-dwelling relict populations. Surprisingly, another species was then described from along the Pacific Coast of Costa Rica.
