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
Widespread in the British Isles but appears rather localised in distribution.
Reported in the Victoria County History (Clark, 1906) from Falmouth. The only modern record comes from remnant old heather around the boulder fields on Carn Galver, Zennor in 2007.
Habitat & Ecology
Feeds on the microflora encrusting the branches and foliage of trees and shrubs, including dwarf shrubs such as heather.
Burning of old heather.
Carn Galver is owned by The National Trust.
