Davey, P., 2009: A species restricted to southern and south-western Britain, the larva feeding on lichens growing on oak (Quercus spp.), beech (Fagus sylvatica) and conifers. In Dorset, "an insect of most uncertain appearance, which occasionally occurs in large numbers." (W Parkinson-Curtis ms). The species appears to be well established within mature oak woods and conifer plantations at the present time: Yellowham Wood, six larvae in actinic light trap on 6 October 1998 (D Hallett). The moth takes to the wing above the forest canopy on sunny days, and undoubtedly disperses over short distances: Bottlebush Down, in flight five metres above ground at midday in warm sunshine over an arable field and four-hundred downwind from mixed woodland on 24 June 2003 (P Davey). Occasional light trap records of adults well away from core habitat suggest occasional medium-range dispersal too: West Bexington, a massive total of ninety-five on 1 July 2006 (R Eden), Durlston, two on 15 June 2004 (Dr J Clarke).
