    The adult moths of this species are dimorphic. The males have a wingspan of about 5 cms. The females have a wingspan of about 8 cms. Both sexes have green forewings with a broad brown band across each one, and have brown hindwings, but the males are rather paler than the females. The green colour fades to brown in Museum specimens.
