Color and Appearance: When the wings are open, the dorsal surface forewing is primarily yellow having black bands along the edges, similar to the hind wings. The secondary wings display yellowish orange to red eyespots close to the tails, with a black pupil in each eye. The anal cell of the secondary wing is predominantly yellow. When the wings are closed, both wings look almost identical on the ventral side, except that the colors and patterns are a bit faint.
