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
Found only in southern England, south of a line from the Bristol Channel to the Wash, excluding East Anglia.
Locally common on The Lizard, with a handful of sites in West Penwith. A small isolated colony was found by Roger Penhallurick in 1980 at the Tidna valley, north of Bude, but this has not been seen since 1991.
Habitat & Ecology
As its common name suggests, this species is normally found in woodland rides, sometimes spreading to adjacent grasslands. However, this is not the case in Cornwall, where it is invariably found to be a species of open heathland, well away from woodlands.
