Davey, P., 2009: A declining species in south-east Britain, now restricted to a handful of counties in south-east England and East Anglia, the larva feeding on the flowers and seeds of herbaceous plants. In Dorset, there is slim evidence to support a resident status for this species. Any colony that was once established has long been extinguished by the loss of unimproved herb-rich grassland habitat on chalky soils since the Second World War. The following record was from a typical habitat for the species: Badbury Rings, (S Scarsdale Brown). Core habitat at the site is now just 25 hectares in extent, it has become isolated by the surrounding grassland that has for a long time now been improved. The Marbled Clover and the Shoulder-striped Clover2402 were separated into two distinct species in 1938, and records prior to this date were all referred to as Marbled Clover Heliothis dipsacea.

Diagnostics include: dark basal streak absent; inner edge of dark median band meets basal edge of forewing almost at a right angle, not 45 degrees.

All records below refer to immigrant moths seen at light unless otherwise stated; the majority backtrack to central northern Europe. The second example in 1995 was disturbed from its preferred unimproved herb-rich chalk downland habitat, but was probably a remnant from the notable immigration a week earlier which yielded the example trapped at Arne; no other moths have been seen on Melbury Down either before or since: Dorchester, at light on 16 June 1951 (Dr A Lisney), Scar Bank, at light on 6 August 1934, 14 August 1947, 26 July 1948, 19 August 1949 (A Russell), Melbury Down, by day on 9 August 1995 (P Davey), Arne, at MV on 1 August 1995 (B Pickess) - see Portland2099 account for weather map, West Moors, at MV on 8 August 1997 (B Baker).
