Pill woodlouse  (Armadillidium vulgare)

This species is very common in the south-east of England, is found in parts of western and northern England and becomes rare in Scotland (2).

Occurs only on calcareous soils, except in coastal areas (2), and is able to withstand much drier conditions than most other woodlice (3). It shows a distinct preference for chalky or limestone sites with stony turf (2).
