Davey, P., 2009: This sub-species is widespread across central and eastern parts of England and south-east Wales, the larva preferring meadow vetchling (Lathyrus pratensis) and red clover (Trifolium pratense), but also eating other vetches and peas. The moth is local in Dorset, and tends to be associated with meadow vetchling growing along railway and road-side embankments on chalky soil, and within unimproved grassland chiefly on ill-drained clay soil, but also along the coast, however colonies are rarely large. The adult is on the wing at the same time as the Five-spot Burnet ssp. palustrella170. Narrow-bordered Five-spot Burnet and Five-spot Burnet ssp. decreta170 colonies co-exist at Kingcombe, Rooksmoor and Pamphill. An example of ab. citrina, a form where the red colouration is replaced by yellow, see illustration, was found paired with a typical-form male on the Monkey Jump roundabout in Dorchester by Dave Foot on 21 June 2003.
