Davey, P., 2009: A locally frequent species in England, Wales and southern Scotland but scarce elsewhere, the larva feeding on yew (Taxus baccata), norway spruce (Picea abies), douglas fir (Pseudotsuga menziesii), pine (Pinus spp.), oak (Quercus spp.) and birch (Betula spp.). In Dorset, the moth is common very locally in mixed woodland containing norway spruce or douglas fir. The moth has been noted in very small numbers in 'pure' oak woodland where there is negligible conifer, such as Yellowham Wood, Piddles Wood and Holt Forest. The following light trap records refer to singletons trapped well away from woodland habitat, suggesting occasional medium-range dispersal: Walditch, on 12 July 2002 (M Parsons), West Bexington, on 6 August 1997 (R Eden), Shapwick, on 27 July 2002 (P Davey), Durlston, on 29 July 2004 (C Manley).
