Davey, P., 2009: A species found in all parts of Britain, the larva feeding on scots pine (Pinus sylvestris), spruce (Picea spp.) and western hemlock (Tsuga heterophylla). In Dorset, the moth is common in conifer plantation. The flight time covers four months. This is likely to be a combination of a single brood in July, plus a double brood with the first generation between early May and late June and a second from late July to mid-September. The national norm is for a single brood in northern Britain in June, and a double brood in the south. Of the four hundred and sixty-four Tawny-barred Angles trapped at Arne Wood between 1974 and 1995, 98.5% were of the typical form, and 1.5% was of the melanic form, ab. nigrofulvata. The moth is occasionally found well away from conifer habitat, and medium-range dispersal from is suspected for the following: Portland, at MV light on five occasions between 24 July and 3 August 1996, 6 July 1999, 8 July 2001, 27 June 2003, 5 July 2003 (M Cade).
