The descriptive text, below the map, is from the Cornish Red Data Book (2009). The map on this web page depicts the organisms distribution and shows the records made pre-2000 and those made since.
Range & Status
Modern records are almost entirely confined to sites in south-west England and the heaths of Dorset and the New Forest, Hampshire. It utilises a variety of habitats including coastal landslips, unimproved cliff tops, sandy heathland, sand pits and sandy beaches. It has been recorded from numerous Cornish sites, both north and south coasts, in some of which the populations are quite large. Work for the Provisional Atlas' has revealed that it is more common and widespread than previously thought, at least so in Cornwall, where there are in excess of 12 post-2000 sites.
