The wings of both males and females are tawny yellow. However, the wings of females are more yellowish then males. Male wings are darker towards the tips and transparent or clear towards their base. The veins on the leading edges or both wings, or costal veins, are pronounced with a darker stigma (prominent wing cell) two-thirds out from the thorax. The wings of the males have six enclosed cells on the front wings (Goulet and Hüber 1993). The tegula (a hardened plate at the base of the front wing) does not completely cover the base of the wing.
