Might be confused with L. marginata but this is a smaller species and the lateral bands are thinner and higher on the back forming conspicuous 'tram-tracks' across the mantle to the tail. The predominant ground colour has yellowish or pinkish undertones. Increasingly common, especially in urban areas.
55-70 mm.
Indigenous in Spain and the Balearic Islands but spread by human activities to many other parts of the world including North America, Africa, Australasia and the British Isles.

First recorded in the British Isles in 1948 when specimens were collected at the Palm House in Belfast Botanic Gardens (Quick, 1960). Comparatively recently (since about 1980) it began to naturalise in gardens in the vicinity of Dublin, since when it has spread explosively in natural and semi-natural habitats, mainly gardens or other disturbed places but increasingly under bark on trees in woodland.
