It is found from western Europe east through the Palearctic (northern Asia Minor, southern Siberia, Middle Amur, Primorye, Sakhalin, Kunashir, Zhejiang) to Korea and Japan.
The length of the forewings is 15–17 mm. Both wings dark brown grey, with the costa of the forewing and the fringes light bright yellow, especially in the female. The ground colour is often more or less lightened with ochreous, sometimes almost clay-colour (ochreola Hbn.), or nearly whitish (helveola Ochs.) or of an indefinite intermediate shade (luteola Hbn.). In pavescens Butl. from Hokkaido (Island of Yezo), the wings are dirty greyish yellow; the hindwing lighter.
