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
Restricted to a few sites across England, where it has become increasingly scarce.
A single old record from Isles of Scilly (F. Holme, 1845).
Habitat & Ecology
Favours dry sandy situations, such as sand dunes and heaths.
Agricultural intensification; abandonment of rough grazings, leading to coarsening of the vegetation; development pressure on ' waste' land.
Much of the coastal sand dunes and sandy heathland is now protected within SSSI.
Development in the islands is controlled by the Duchy of Cornwall.
