It is mainly found across the extreme south-east of England, but outlying populations occur elsewhere, notably Co. Dublin, Ireland and Cumberland coast, northern England. It favours disturbed habitats, whether this is on the coast (e.g. ‘soft’ slumping cliffs) or synanthropic habitats (e.g. waste ground, railway lines and gardens).

It typically takes refuge under mat-forming plants, beneath stones and dead wood, or among leaf-litter, tussocks, rubbish and other debris.

This summary is based on the detailed account in Gregory (2009).
