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.
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.
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. [41]
Pill millipedes are relatively short-bodied compared to most other millipedes, with only eleven to thirteen body segments, [2] and are capable of rolling into a ball when disturbed, as a defense against predators. This ability evolved separately in each of the two orders, making it a case of convergent evolution, rather than homology.
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 ]
Like members of the woodlice family Armadillidiidae, armadillids are capable of enrolling into a sphere (conglobation), and are commonly known as pill bugs. [4] [5] Some species, however, have secondarily lost their conglobation ability. For example, a species exist in which the males lack the inner face of the coxal plates and are therefore ...
