Davey, P., 2009: A local species in Britain, the larva feeding on birch (Betula spp.), bilberry (Vaccinium myrtillus), bog myrtle (Myrica gale), and heather (Erica spp.). In Dorset, the moth is common very locally in situations where bog myrtle occurs, chiefly in alder-swamps, bogs and marshes on sandy soil across the Poole basin. The moth may occasionally be found at rest on the trunks of isolated heathland birches or pines. Much of the moth's wetland habitat falls within existing conservation areas; it is recommended that this species be included in management plans for mire habitat containing bog myrtle. The following light trap records are of singletons encountered well away from core habitat suggest occasional short-range dispersal: Bere Wood, on 11 April 1977 (BW), Shapwick, on 7 May 2000 (P Davey), Ashington, on 12 May 1990 (J Fradgley), Wimborne, on 19 April 1985 (M Brooks), Brownsea Island, on 27 April 1967 (A Bromby).
