The larvae feed on false-brome (Brachypodium sylvaticum), wood small-reed (Calamagrostis epigejos), upright sedge (Carex stricta), tufted hair-grass (Deschampsia cespitosa) and tall fescue (Festuca arundinacea). They mine the leaves of their host plant. Larvae can be found from autumn to June. The species overwinters within the mine.
