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 Bishop' s Wood, Truro. The only modern record comes from Ethy Wood, Lerryn Creek in 1983.
Habitat & Ecology
Most known sites are ancient Oak Quercus sp. woodlands, where it feeds on the microflora growing on the foliage of trees and shrubs.
Ancient woodlands now have some protection from felling, and Ethy Wood is owned by The National Trust.
