This species is so named due to the colour of the hindwings and the markings on the forewings which make it unmistakeable. There is little variation although on rare occasions the pinkish markings are replaced with yellow, or the forewing is red with a black border or the wings are completely black. Easily disturbed by day and flies in sunshine. Also flies after dark.
