This Caterpillar starts of as one of a row of eggs. The eggs are oval, and have a diameter of about 0.5 mm. The eggs are white or pale green.
The young caterpillars are yellow and have stiff hairs all over.
Later instars become olive green with tubercles (scoli) each of which has a cluster of short stiff hairs. The scoli are also green except in the 3rd instar, in which they become red.
The caterpillars have been found feeding on the foliage of a variety of trees such as :
The caterpillars can grow to a length of about 10 cms. The caterpillar pupates in a stiff oval cocoon on the food plant or nearby structure.

However, the wings often have grey areas, which may extend across the whole of the upper surface of the wings. The moth typically has a wingspan of 14 cms.
The species occurs in
