[3] Androniscus dentiger is a small woodlouse, at only 6 mm (¼ in) long, and is characteristically pink or orange in colour, with a yellow stripe along the midline of the dorsal surface,[4] which divides in two towards the animal's tail.

[5] In the British Isles, A. dentiger is found in a wide variety of habitats, including coastal areas, gardens, old quarries[4] and caves.

[6] It lives where there is a significant amount of lime available, and is reported to show a preference for Anglican churchyards over Catholic ones because the older, Protestant churches used ox-blood mortar.

[7] In the south of its range, A. dentiger is primarily troglobitic, with populations in different cave systems being genetically isolated by the lack of migration between caves.

[9] In North America, A. dentiger is only known to occur in greenhouses.
