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 ]
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.
Pill bugs in the family Armadillidiidae are able to form their bodies into a ball shape, in a process known as conglobation. Conglobation has evolved independently in several families; this behaviour is shared with pill millipedes (which are often confused with pill bugs), [ 7 ] armadillos , cuckoo wasps , and some extinct trilobites . [ 8 ]
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]

The good news for the milkvetch plant is that they usually need wildfire to sprout — meaning dormant seeds now have a massive new habitat for a new crop of the rare shrub.
Armadillidium nasatum occurs in patches in southern England, with concentrated areas in its range and sporadic occurrences in Ireland. [2] It lives in dryer areas than most woodlice, is synanthropic, and is frequently found in non-inhabited areas such as railway lines and industrial waste ground. [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 ...
