Both forewings and hindwings are light-green coloured, but fade with increasing life span to yellow-green to yellow-white.

There is an outer and a fainter inner, slightly curved and continuous, white cross line on the front wings.

The inner (antemedian) is strongly curved and usually with two small, slight teeth directed distad, the outer (postmedian) is nearly parallel with distal margin, not dentate.
