Davey, P., 2009: A local species confined to south-east England, the larva feeding on sheep’s fescue (Festuca ovina). In Dorset, the moth occurred at a single site, Parkstone golf links, more then sixty years ago. There were no further records until 1979 when a singleton was trapped on Studland. A second individual followed in 1982, this time on Portland, and a further four moths were trapped in early August 1994, three at Christchurch and one at Gaunts Common. Colonies were then detected across the Poole Basin subsequently.
At the present time, the species is well established very locally on dry heathland sites, where fine-leaved sheep’s-fescue (Festuca filiformis) and bristle bent (Agrostis curtisii) are potential host food plants. Conservation agencies should include this species in habitat management plans for sites containing dry heathland. The species has a partial double-brood, the first brood nearly six times larger on average than that of the second.
