Forewing: a broad outwardly oblique white transverse band that crosses from a little beyond the basal third of the costal margin to the dorsum, its outer half hyaline (glass like), followed by a hyaline triangular area that does not reach the costa or the termen but is traversed by conspicuously black veins.

Underside similar, but the ground colour opaque brownish black; a broad outwardly ill-defined earthy-grey streak along the base of the wings produced slightly down the dorsal margin of hindwing and along the costa of the forewing; the oblique white band on the hindwing joined by a cross sinuous short white line from the dorsal margin to its apex; below this latter a number of irregular white spots on the tornal area.

It is also found in Thailand, Laos, Vietnam, southern China, Kampuchea, Malaysia, Indonesia, Brunei, and the Philippines.

The larva in later instars becomes apple green, darker on the back, with three narrow yellow stripes on the seventh to tenth segments, and a buff line just above the legs from head to tail.

It is only 22 mm long and the colour varies from yellow green on young growth, to emerald on mature leaves.
