Davey, P., 2009: A species that was formerly resident in Britain, the larva feeding internally on spruce (Picea spp.) cones. This huge Pug has undergone a dramatic decline in Britain, possibly due to the harvesting of spruce as a crop before maturation, and the consequent lack of mature cone-bearing trees. In Dorset, spruce tends to be harvested in this way, and the tree has never been native. The sole historical colony on record was from Purbeck at the start of the twentieth century: Norden Copse, male flushed from fir on 19 July 1902, female on 23 July 1902 (Reverend E Bankes), Norden Plantation, female flushed from fir on 2 August 1902 (F Hanbury), in flight at 8:40pm on 17 July 1905, two males flushed from fir on 18 July 1905, two males in flight at 8:45pm and 9:15pm, respectively on 20 July 1905, male in flight at dusk on 31 July 1905, male at rest on rush stem at dusk on 31 July 1905, male beaten from scotch fir on 25 July 1906, and Scotland, disturbed on 15 July 1905 (Reverend E Bankes). More recently, moth research in a wood full of Norway spruce in the west of the county, has revealed a colony: Chedington Wood, at MV light on 14 Jul 2007 and two on 1 July 2008 (P Davey et al). It is recommended that groups or groves of mature cone-bearing Norway Spruce be retained to support the Cloaked Pug colony in Chedington Wood.

Elsewhere, the following records are of immigrants: Puddletown, at MV light on 4 July 2003 (H Wood Homer), Higher Hyde, two at MV light on 7 July 2001 (Mark Forster et al).
