Davey, P., 2009: A local species in southern England, the larva feeding in the cones on the seeds of Norway spruce (Picea abies), and on pine seeds (Pinus spp.), at least on the Continent. Infested cones become stunted and fall from the tree before achieving full growth. In Dorset, the moth is very local and mostly at low density.

Many (light trap) records hale from heathland localities on sandy soils where mature scots pine (Pinus sylvestris) and lodgepole pine (Pinus contorta) grow and where Norway spruce is largely absent, and the moth has recently been bred from fallen scots pine cones (M Parsons): Morden Bog, two on 7 July 1999, 6 July 2000 (P Davey), 12 July 2000 (Dr P Sterling), Gore Heath, on 12 July 1999 (Dr P Sterling), Wareham Forest, on 3 July 2006 (M Parsons), Canford Heath, on 22 July 2000 (P Sharp) and 18 July 2006 (M Parsons), Ferndown, on 2 August 1991 (R Cook), Town Common, on 2 August 1996 (P Davey). However, localities where Norway spruce trees grow also host the moth: Buzbury Camp, bred from Norway spruce cones from a wood, and Badbury Rings, bred from spruce cones from a wood, entirely destroyed about 1940 (S Scarsdale Brown), Gaunts Common, at MV light on 6 June 1992 (P Davey), Chedington Woods, eight at MV light on 14 July 2007 (P Davey). A potential second brood example was trapped following the warm summer of 2006: Chedington Woods, at MV light on 28 September 2006 (P Davey).
