This species is believed to be restricted as a native to the coasts of south and eastern
England from Dorset to North Norfolk (Cope & Gray, 2009). Our populations are not a vast
distance from the East Anglian coast and have found an alternate niche on sparsely
vegetated substrates associated with old clay and gravel workings.
