In males, the hindwing is 42 to 45 mm in length and the total body length ranges from 46 to 49 mm. The thorax and eyes of the male are orange-brown. The abdomen is also orange-brown, but has black markings near the end (segments four to ten). The hindwing base is yellowish brown but there is an irregular brown band running for a short distance from the inner margin, parallel to and just in from the hind margin. The female has a similar appearance, but with less dark markings at the abdomen.
