Davey, P., 2009: A rare species confined to south-east England plus outlying colonies in Worcestershire and south Wales, the larva feeding on fungi growing on fallen and rotten trees and stumps. In Dorset, the moth has been seen on five occasions at light traps: Rooksmoor, on 23 July 1997 (P Davey), Harman's Cross, on 20 July 1991 (B Withers), Ferndown, on 21 July 1997 (R Cook), Verwood, on 4 August 2004 (S Palmer), Alderholt, on 23 July 2008 (T Morris). Dispersal from colonies in Hampshire or Surrey was likely for the 1997 and 2004 examples and massive immigration from abroad coincided with the observation of the 2008 example. However, targeted searches for the highly cryptic larvae on fungi growing on fallen rotten birch trunks within dry woodland on sandy soils in the east of the county in late spring and early summer may well prove productive, particularly as the species appears to have extended its range westwards into the New Forest in recent years.
