Davey, P., 2009: A double-brooded species that is resident in East Anglia on the Breck and on coastal sand-dunes, otherwise a very rare immigrant, the larva feeding abroad on wild thyme (Thymus polytrichus), field bindweed (Convolvulus arvensis), trefoils (Lotus spp.) and knotgrass (Polygonum spp.). The moth is widespread across Europe, colonising unimproved open grassland habitat. In Dorset, the following record suggests that the Tawny Wave was once resident in the far north-east of the county, in habitat similar to that found in the Breck district where sand or leached soil overlies chalk: Cranborne, bred from larvae found feeding at night on lady's bedstraw (Galium verum) (F Haynes per W Parkinson Curtis). This unusual geology still supports ideal habitat on Martin Down on the Hampshire side of the Dorset border, but matching habitat on the Dorset side of Bokerley Dyke has long since been obliterated by the plough.
These records refer to immigrants trapped at light: Portland, on 12 August 1994, 18 August 2002 (M Cade), Scar Bank, on 21 August 1935 and on 22 August 1935 (A Russell), Studland, on 7 August 1969 (Ent Rec 82:31), Iford, on 5 August 1994 (M Jeffes).
