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 and eastern Britain, but with very few recent
Known from one old record on north coast: Newquay, 1880, E.D. Marquand.
Habitat & Ecology
Favours sparsely-vegetated ground on dry freely-draining calcareous soils and presumably a species of wind-blown shelly sand vegetation; probably feeds mainly on seeds.
Development of sand dune systems and coastal cliff lands for recreation; coarsening of vegetation through lack of grazing and/or trampling, with consequent loss of open sandy areas; coastal protection works.
Much of the more sensitive coastline is now protected by SSSI designations. This species is listed on the UK BAP Priority Species list (2007).
