Wingspan 45-60 mm. Flies from early June to mid-August in one generation A butterfly flies in 2 generations when the year’s first newly emerged adults (1st generation) bring a new “brood” (“children”) capable of flight into the world in the same year. With 3 generations there are “grandchildren” as well in the same year. The number of generations determines in how many months of the year we can see the butterfly.. Seen in the clearings of the plantation and on the neighbouring fallow fields, as well as on the dike. The flight is handsome and gliding. Not fussy about flowers but seems to prefer Thistles. The eggs are laid on Wild Pansy and various violets. Overwinters as a caterpillar. The species is rare and declining, but the population here seems stable.
