Common on calcareous grassland, sand-dunes, farmland and open woodland throughout the British Isles. Widespread and common in Hampshire and on the Isle of Wight. Wingspan 32-40 mm. Superficially resembles Common Rustic Mesapamea secalis
and its congeners, but postmedian fascia highly dentate (sinuate in Mesapamea
), with the main confusion species either extremely rare (Dumeril's Rustic L. dumerilii
) or with a limited coastal distribution (Sandhill Rustic L. nickerlii
). Larva feeds on roots and lower stems of various grasses, including Common Couch, Red Fescue, Sheep's-fescue, Tall Fescue and some cereal crops.
