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
Southern Britain, very local.
Reported in Cornwall in the Victoria County History (Clark, 1906) but only twice in the
following decades: in a Gorse Ulex spp. hedge at Tintagel (Butler, 1909) and commonly at Gwithian Dunes in 1934 by R.T. Bannister. More recently it has been discovered in the sand dune systems at Rock and Harbour Cove (Alexander, 2002). Subsequently seen at Rock on two occasions in 2005 by Ian McClenaghan.
Habitat & Ecology
Appears to favour unimproved grasslands on dry freely-draining soils, the adult having a partially subterranean habit in the friable topsoil, and may specialise in feeding on root aphids.
Development pressure on sand dunes.
The two dune areas are protected from development.
