The length of the wings is 33–40 mm for males and 36–41 mm for females. The upperside of the males is dark brown, with bright sky-blue diagonal bands on the forewings and blue markings on the hindwings.
They are fast flyers and fly in an erratic fashion. They may land suddenly on leaves or on the ground if decaying fruit is present. They are also attracted to human perspiration.
