Key characteristics

  • A large glossy, globular shell
  • Ground colour varies greatly, from yellow through brown to red or pink with up to five dark spiral bands or none

18-25 mm.

World Distribution

Unlike the very similar Cepaea hortensis, which is circumpolar, this species is confined to central and western Europe south to the Mediterranean. Distribution type: European Southern-temperate (83).

Irish Distribution

Frequent throughout but most abundant in coastal localities, particularly dunes.

Ecology

  • Mostly in shaded, rocky or humanly disturbed habitats such as gardens .
  • Can be sparsely distributed on acid soils where shells are thin and fragile
  • Most abundant and well developed on coastal dunes
  • Generally prefers sheltered dry places

Red List status
