Early instars of this Caterpillar green with a pale brown head, a black forward curving tail spike, and a finely broken white stripe along each side.
Later instars become dark grey, speckled with pale dots, and have a green and/or orange circle around each spiracle edged below by a pale streak. The tail spike develops a pale yellow granulation, and still curves upward in the later instars.
The caterpillar has been reported to feed on various plants from RUBIACEAE, including :
The caterpillar grows to a length of about 7 cms. Pupation occurs in a loose cocoon amongst the ground debris. The pupa is brown with a row of dark spots along each side, and an incomplete black line along the back and the underside. The pupa has a length of about 4.5 cms.
The adult moths have brown forewings with a faint sinuous pattern. The hindwings are dark brown, each with a pale line along the costa, and a broad diagonal yellow band. The body is brown with a bunch of hairs on the tail. The wingspan is about 5 cms.
The eggs are pale yellowish green, and oval with a length of about 1.5 mms. The eggs are laid singly on the undersides of foodplant leaves.
The species is found as the subspecies corythus across south-east Asia, from the Cocos Islands to New Caledonia, including
The adults of subspecies approximans T.P. Lucas, 1891 can be distinguished from the other subspecies as the hindwing yellow band does not reach the costal pale line, and the tail tuft has orange hairs.
This subspecies occurs in Australia in
