The following description of the caterpillar and chrysalis is given
by Stoll:--“The head of this beautifully coloured caterpillar is dull
yellow, with two short rays and small spots of black. The head is
furnished with two long black spines garnished with short stiff hairs.
The first five segments of the body are reddish-brown, spotted with
black. The belly is white, and the anterior legs black. The rest of the
body is reddish-brown; but from the sixth to the eleventh segment, the
back is of a beautiful yellow, and bordered on the sides with short
black and white rays. The back is armed with four long spines, the last
of which, placed on the eleventh segment, is curved backwards, and
very similar to the horns with which most of the caterpillars of the
Sphinges are provided. The intermediate and posterior legs are yellow.
It feeds on the leaves of the Cashew tree (_Anacardium occidentale_),
and transforms into a perpendicular chrysalis of a yellow colour,
spotted with black, garnished with black spines on the head, thorax,
and back. When the butterfly is about to appear, the yellow colour
changes into white.[35]”
