Davey, P., 2009: The commonest heathland macromoth species in Britain, the larva feeding on heather (Calluna vulgaris) and bell heather (Erica cinerea). In Dorset, the moth is abundant on heathland. In favourable years trap totals are large, for example, 5000 at Furzebrook in 1972 and 2400 at Matchams in 1986. There are many observations of short or medium-range dispersal away from heathland, see also the Narrow-winged Pug1846 account. Interestingly, colonisation away from heathland has been observed in Europe for this species.
