In Hampshire and on the Isle of Wight locally common on downland amongst Yellow Rattle and less so in acid woodland where the foodplant is Common Cow-wheat, and occasional elsewhere. Wingspan 20-26 mm. The most likely confusion species is Algedonia terrealis, which see for differences. Larva feeds on Yellow-rattle and Common Cow-wheat.
