Invertebrate Iridescent Virus 31
''Invertebrate iridescent virus 31'' (IIV-31), also known informally as isopod iridovirus, is a species of invertebrate iridescent virus in the genus ''Iridovirus''. Oniscidea (commonly known by a variety of names including ''woodlouse'', ''pillbug'', ''slater'', ''rolly-polly'', ''potato bug'', et al.) 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. Taxonomy In earlier centuries, blue individuals of otherwise drab oniscidean species had been discovered. They were sometimes interpreted to be new subspecies and were described as such: ''Ligidium hypnorum coeruleum'' Lereboullet 1843 and ''L. hypnorum amethystinum'' Schöbl 1861 (in reference to cerulean and amethyst, respectively). In 1980, the first research was published showing that the phenomeno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Porcellio Scaber
''Porcellio scaber'' (otherwise known as the common rough woodlouse or simply rough woodlouse), is a species of woodlouse native to Europe but with a cosmopolitan distribution. They are often found in large numbers in most regions, with many species (shrews, centipedes, toads, spiders and even some birds) preying on them. Taxonomy One subspecies, '' Porcellio scaber lusitanus'', is currently recognized. Two other subspecies were historically deemed valid but are no longer recognized. ''P. s. americanus'', described in 1932, was considered endemic the Americas. ''P. s. japonicus'' was described in 1928 and believed to be endemic to Japan. Both subspecies were synonymized with the nominate in 2020. Distribution ''Porcellio scaber'' is found across Central and Western Europe. In the United Kingdom, it is one of the "big five" species of woodlice. It has also colonised North America, South Africa and other regions including the remote sub-Antarctic Marion island, largely th ...

Porcellionides Pruinosus
''Porcellionides pruinosus'' is a cosmopolitan woodlouse that is native to Europe, and is suspected to consist of very closely related species. Ten subspecies are recognised. The species carries ''Wolbachia'' endosymbionts, which is an alpha-proteobacterium that is known to modify the reproduction of their crustacean hosts by inducing cytoplasmic incompatibility or feminisation. See also *List of woodlice of the British Isles Woodlice are the most species-rich group of terrestrial crustaceans.

''Porcellionides pruinosus'' as a pet Since it is easy to keep, the species is bred as a food source for pets or as a pet itself. There are now numerous color forms such as "Orange", "Powder Orange", "White Out", "Oreo Crumble", "Red Koi" and "Powder Blue", although this is the nominate form. Some cultivate ...

Porcellio Laevis
''Porcellio laevis'' (Common name, commonly called the swift woodlouse, dairy cow isopod, or smooth slater in Australia) 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. This species of woodlice is distinctively large, appearing up to 20mm long with a smooth dorsal surface. The males can be identified by their long, spear-shaped uropods. ''Porcellio laevis'' has a smooth dorsal surface, which separates its visually from many other species of the Porcellio genus. It is commonly kept as a pet due to its somewhat easy care requirements and the variety of color morphs available. The species is easy to keep and can be easily established in a terrarium within a few weeks. "Dairy cow isopod" is a commonly used name for a readily available piebald strain of the species.

Porcellio Dilatatus
''Porcellio dilatatus'' ( Commonly known as the Giant canyon isopod) 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 long, are brown coloured and striped. They can be found feeding on alder leaves, but mostly feeds on organic food substrates, such as lettuce (''Lactuca sativa'') in the wild. It also feeds on inorganic metal salts. Pests The species are considered to be house pests, that can be found in greenhouses, seed boxes, and flower pot A flowerpot, planter, planterette or plant pot, is a container in which flowers and other plants are cultivated and displayed.

Porcellionidae
Porcellionidae is a terrestrial family of the order Isopoda. This family contains 530 species, found on every continent except Antarctica. The ventral plate of the thoracic exoskeleton flare out slightly over the legs. This "flare" is called the ''epimeron''. The uropods, antenna-like structures at the back of the specimen, are flattened out and spearlike, and extend beyond the last exoskeletal plate. Genera The family contains 19 genera, and two further genera (''Inchanga Inchanga is a village in KwaZulu-Natal, South Africa, approximately halfway between Durban and Pietermaritzburg.

Philoscia Muscorum
''Philoscia muscorum'', the common striped woodlouse or fast woodlouse, is a common European woodlouse. It is widespread in Europe, the British Isles and is found from southern Scandinavia to the Ukraine and Greece. It has also spread to Washington and many states in New England, also the mid-Atlantic states of Pennsylvania and New Jersey, as well as Nova Scotia.
