Distribution:

The typical subspecies is known only from Europe, where it has been found in central Europe, Italy, Albania, Romania, Bulgaria, as well as in the north-western and central part of European Russia (Karsholt & Nieukerken 2010). Vertically, the taxon has been documented from the colline level up to at least 1000 m a.s.l. (Kurz & Kurz 2010).

The animals are gregarious and live locally at the edges and outskirts of woodland, as well as on clear-cuttings, rich in tall-herb vegetation and bushes. They are especially found at the edge of spruce forests. Imagines are day-active and fly in one generation in July (Kurz & Kurz 2010).

Diagnosis:

In Europe, the species is unmistakeable due to markings and colouration of the forewing upperside.
