Davey, P., 2009: A widespread species in south-east England, more local elsewhere, the larva feeding on the flowers of common milkwort (Polygala vulgaris) and possibly lousewort (Pedicularis sylvatica). In Dorset, the moth occupies three biotypes. It is locally abundant on dry unimproved short-turf grassland on chalky soil - in these situations the foodplants are common milkwort and chalk milkwort (Polygala calcarea). It is locally frequent on sandy soil where heath milkwort (Polygala serpyllifolia) grows in woodland rides, plantations or among heather. The third habitat is found at Powerstock Common, where milkwort occurs on the grassy embankments of an old railway line cut into clay soil. The moth is double brooded in the county, with the peak of the second brood more than three times larger on average, than the peak of the first. It is active during the day, particularly in sunshine and is easily disturbed from its resting-place on the ground. It also flies at night and in fact more than half of the county's records originate from light traps. On these occasions it is often noted some distance away from core habitat.
