Davey, P., 2009: A local species in England and Wales, the larva feeding on common mouse-ear (Cerastium fontanum) and field mouse-ear (Cerastium arvense). In Dorset, this handsome day-flying species is widespread but local and usually at low density but potentially under-recorded due to its small size and to its similarity, at least on the wing, to day-flying Pyrausta micromoth species. It tends to occur in unimproved grassland, on verges and in gardens on all soil types, where common mouse-ear is abundant. A strong colony of the moth has taken up residence at a site in the process of being reverted from improved to unimproved chalk grassland by the National Trust on the Kingston Lacy estate: Shapwick, roughly one hundred present in sunshine on 12 May 2002 (P Davey), fifty in sunshine on 14 May 2003 (P Davey, C Manley). An alternative foodplant for the species, field mouse-ear, was once widespread in short turf on chalky soils and on heathland tracks. However, the plant has declined significantly, for example it has disappeared from Parley Common, a locality once colonised by the moth, and remains only on ancient earthworks in the far north-east of the county.
