Davey, P., 2009: A species found mainly in south-east Britain, more coastal elsewhere but largely absent from Scotland, the larva feeding on restharrow (Ononis spp.). In Dorset, the moth is at low density along the coastal belt. The records listed below refer to occasional singletons that turn up inland. These may either be wanderers from the coast or originate from colonies on what remains of unimproved grassland on chalky or clay soils inland where common restharrow (Ononis repens) is still found. The national norm is for a single brood in June and July, but the moth has occasionally been noted as early as the first week of May and as late as the last week of August in Dorset. This suggests a bivoltine cycle in favourable years, as happens on the Continent.
