This Caterpillar is initially green with blue-green eyespots ringed with yellow outlined in brown, one on each side of each of the first and second abdominal segments. Initially the caterpillar has a pale green straight tail spike.
In later instars, the tail spike becomes red.
Mature instars often become brown, and the tail spike becomes black with a white tip and curved backwards.
This species is the only one in SPHINGIDAE with caterpillars that have two equally sized eye spots each side of the abdomen.
The caterpillars have been found feeding on various species of ARACEAE, including :
The pupa is rather long and thin. It is mottled brown with dark rings around the abdominal segments.
The adult moths of this species are plain brown, with a few faint dark dots. The moths have a wingspan of about 7 cms.
The abdomen of the adult moths has hardly any lateral striation which distinguishes them from the very similar species Theretra latreillei. The adults may be nearly indistinguishable, but of course the Caterpillars are easily distinguished, having two eyespots each side, whereas Theretra latreillei caterpillars have only one.
The eggs are spherical and off-white. They are laid singly on the upper surface of leaves of a foodplant.
The species may be found in:
and also in Australia through
