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
Formerly widespread across southern Britain but has become increasingly scarce in
Found at the cliff bottom at St. Loy, West Penwith, in 1936 by R.T. Bannister, and also an older record from Cubert in 1911 by A.J. Allen. Discovered at Dannonchapel in 2005.
Habitat & Ecology
Sandy or gravelly soils, usually on heathland.
Agricultural intensification along the cliff tops and inland heaths; abandonment of rough grazings, leading to coarsening of the vegetation; development pressure on ' waste' land.
Maintain rough grazings on unimproved land and protect from commercial pressures. A Priority Species under the UK Biodiversity Action Plan.
