Distribution and Habitat

Apparently very rare in Britain, it is known from a handful of southern coastal sites from Devon to Norfolk. However, it has proved extremely elusive, even at known sites, and is certainly very under-recorded.

Specimens have been collected from between the high water mark and the storm drift line on unvegetated or sparsely vegetated shores composed of shingle or sand, either in pit-fall traps or clinging beneath strandline driftwood. At Cole Point, Essex, it was found with Trichoniscus pusillus, Philoscia muscorum, Porcellio scaber and Armadillidium album (Gregory etal. 2001).

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