Overview

Distribution

Range Description

This species is known from southern England, Andorra, Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Ireland, Italy, Latvia, Liechtenstein, Luxembourg, Netherlands, Norway, Poland, Portugal, Russian Federation, Slovenia, northern Spain, southern Sweden, and Switzerland.

It is known in Ireland only from limestone bluffs in the gorge of the River Blackwater at Carrick-a-Brick Castle near Fermoy, East Cork. Its status as a native is questionable according to Kerney (1972), who failed to find living material during a visit to the site in 1971 (Byrne et al. 2009).

Habitat and Ecology
In Britain the lapidary snail is known mostly from limestone rocks and quarries. Elsewhere it is mainly in hedgerows and woods on well-drained, chalky soils (Byrne et al. 2009). On the continent, it is found in rock crevices, on stone walls, in mature forests, and hedges. It seems not to be bound to limestone rocks here.
