Davey, P., 2009: A species with a general distribution over southern Britain, the larva feeding on lichens. In Dorset, the moth occupies a range of different biotypes. It is abundant on dry heathland, locally common among sand dunes, fens, salterns and damp woods, and frequent on dry unimproved grassland on chalky soils. There are very few records from Portland and from the west Dorset coast. Although the moth is on the wing during July and August, the following were likely to have been second brood examples: Arne Wood, at MV light on 24 September 1977, 30 September 1986, 14 October 1990 (B Pickess). Recorded in 38 (95%) of 40 10k Squares. First Recorded in 1930. Last Recorded in 2019. (Data up to end 2019) |
