On the Italian Peninsula the occurrence is limited essentially to the Alps and the Apennines as far as Calabria.

In the East, the distribution area stretches over Russia and Siberia to the Russian Far East, in the South to Asia minor, Cyprus, the Caucasus, northern Iran, Northern Iraq and Afghanistan to Central Asia.

The forewing is grey, with dark dusting; base of inner margin pale ochreous; a short black basal streak and another above anal angle, often obscure.

The larvae feed on a number of plants, including oak, Rubus, Calluna and Vaccinium.
