In the southern Europe the species is widespread from northern and central Spain to Turkey and the Caucasus.

In western Europe it prefers dry to mesophilic habitats in coastal areas, sea-cliffs, open forests, grassland, chalk downland and subalpine valleys, at an elevation up to 2,000 metres (6,600 ft) above sea level.

The forewings usually show five crimson to vermilion spots and a black basic colour, with a strong bluish or blue-green reflection.

The females are similar to males, but the top of the front wing is slightly rounded and the abdomen and the thorax are less hairy.

The caterpillars pupate in an elongated or spindle-shaped yellowish or white cocoon on grasses and other plants.
