[1] It is found in most of Europe (except the Iberian Peninsula and most of the Balkan Peninsula), [2] east to the Russian Far East (Amur, Sakhalin) and Japan. [3] It is also found in North America, including Alberta, Arizona, Manitoba, Michigan, Oklahoma and Ontario. [4]
The wingspan is 18–23 mm. [5] The forewings with apex slightly produced; brown, posteriorly whitish-sprinkled, terminally suffused with white; a broad snow - white pointed median longitudinal streak from base, not reaching second line, lower edge with a projection in middle; second line angulated, silvery - white, anteriorly dark-edged; a triangular white subapical spot; several terminal longitudinal black marks; cilia metallic. Hindwings are grey. [6] See also Parsons et al. [7]
Adults are on wing from July to August in generation per year. [8]
The larvae feed on grasses, possibly including Deschampsia flexuosa .
