It is one of the largest species of its genus, with a wingspan of 35 to 70 millimetres. The upperside of the male is dusky orange yellow with a moderately broad blackish brown marginal band crossed at the apex by yellow veins, while the female is somewhat brighter red with large yellow spots in the dark marginal band. The butterfly flies from May to July and the larvae feed on Astracantha and Astragalus species. Ten subspecies are listed, each tied to a region from Greece, Turkey and Lebanon to the Russian Caucasus, Turkmenistan and several parts of Iran.
