Davey, P., 2009: A widespread species in Britain, the larva feeding on birch (Betula spp.). In Dorset, the moth is common in woodland containing birch. Elsewhere, it is seen only occasionally. Two brood cycles are suspected: the main mid-May and early August double brood, where the peak of the second brood is on average, three times larger than that of the first brood, and a smaller single brood, with the main peak in June. The following singletons trapped in hot summers may have been offspring from the June brood: Arne Wood, at MV on 26 September 1983 and 14 September 1984 (B Pickess). The period of time between the respective peaks of each cycle is roughly seventy-eight days. The national norm is for a single brood in northern Britain in early June, and a double brood further south.
