Davey, P., 2009: A generally distributed single-brooded species in Britain, the larva feeding on norway spruce (Picea abies), douglas fir (Pseudotsuga menziesii), scots pine (Pinus sylvestris) and other conifer trees species. In Dorset, the moth is locally common in conifer plantations and where scots pine is self-sown on heathland. The green form of the moth, ab. prasinana, has been seen in Dorset on two occasions: Studland, 23 July 1994 (R McCormick), and Durlston, on 10 June 2006 (P Davey); a northern France source is likely for both examples. More generally, there are many instances of moths turning up in localities some distance from core conifer habitat, and medium-range dispersal or immigration is suspected for the majority. These include the following second brood examples trapped at light: West Bexington, on 25 September 1994 (R Eden), Puddletown, on 3 October 2002 (H Wood Homer), Woolland, on 17 October 1997 (P Benham).
