Armadillidium depressum

Range & Status

Common where it occurs in south-west England and south Wales but virtually absent from the rest of Britain. Possibly expanding its range nationally, and may be an old introduction to England (Sutton & Harding, 1989 cited in Hopkin, 1991).

Regional Distribution

First recorded in Cornwall in the Mawgan area (SW72), where it was collected by R.S. Bagnall on the 14th May 1943 (Harding, 1977). The specimen which supports the first Cornish record is from a tube labelled A. vulgare (sic) in the W.E. Collinge collection and should be viewed with some degree of uncertainty. Not recorded again in Cornwall until 1989, and from then at five sites, Morwenstow, Danescombe (near Calstock), Polruan, Readymoney and Lower Predannack Cliff.

Habitat & Ecology

This species can be found at sea cliffs and a variety of ruderal habitats including gardens and in or around buildings.
