Armadillidium (/ ɑːr m ə d ɪ ˈ l ɪ d i ə m /) 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.
This ability gives woodlice in this family their common names of pill bugs [1] or roly polies. [2] Other common names include slaters , potato bugs , butchy boys , [ 3 ] and doodle bugs . [ 4 ] Most species are native to the Mediterranean Basin, while a few species have wider European distributions.
Additionally, pill bugs have a thorax consisting of 7 body segments, 5 abdominal segments, and a pleotelson, while Glomeris millipedes lack a visually defined thorax and have 12 body segments total. While the uropods of pillbugs are relatively quite small, flipping a pill bug over will reveal the small uropod overlapping the pleotelson. [ 40 ]
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. [ 2 ]
Philoscia muscorum, the "common striped woodlouse" or "fast woodlouse", is up to 11 mm (0.43 in) long, with a greyish-brown, mottled, shiny body, [10] and long legs, which allow it to move quickly. It is more common in the south of the British Isles, but can be found up to the north coast of Scotland.
Oniscidea (commonly known by a variety of names including woodlouse, pillbug, slater, roly-poly, potato bug, et al.) serve as hosts. Infection is associated with decreased responsiveness in the host, increased mortality and the emergence of an iridescent blue or bluish-purple colour due to the reflection of light off a paracrystalline ...
The giant isopods are noted for their resemblance to the much smaller common woodlouse (pill bug), to which they are related. [3] French zoologist Alphonse Milne-Edwards was the first [4] to describe the genus in 1879 [5] after his colleague Alexander Agassiz collected a juvenile male B. giganteus from the Gulf of Mexico.
Armadillidium depressum, the southern pill woodlouse [5] is a large, relatively common British species of woodlouse characterized by its "splayed" appearance. Description [ edit ]
