The caterpillars of this species are found in great 

 quantities on the leaves of a species of Datura, the eggs 

 being deposited in clusters of about two hundred on the 

 underside of the leaves. The caterpillar is quite smooth, 

 with a velvety black skin and a red head.

When full-fed the caterpillar becomes suffused with a 

 greenish tint, and hangs itself up by the tail to undergo 

 pupation. The chrysalis is a very compact and neat one. 

 It is of a semi-transparent brown colour, thickly dotted 

 with black.
