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 across Europe to Russia, but known in Britain mainly from large ancient oak woods in Hampshire, Wiltshire, Sussex and Kent (Waring & Townsend, 2003). Recently found in North Devon (McCormick, 2001) and so could occur in woods in north Cornwall.
Single specimens recently recorded from Cornwall only from one site at Herodsfoot
(Smith, 1961) and again in 1969 (Smith, 1997). This small, inconspicuous species may still be present here but overlooked, although moth trapping in this area has failed to produce more records.
Habitat & Ecology
The adult inhabits woodland where the larvae feed on Oak Quercus spp. and Beech
Fagus sylvatica .
