Biology.
The larva was described by Gardner (1947) and illustated by Kuroko &
Lewvanich (1993). It is a slender spindle shape, tapering at each end. The
colour is a darkish, olive green-brown, with a conspicuous pale yellow stripe
along each side that extends from the head to the anal prolegs, which are
splayed out behind. Kuroko & Lewvanich noted two forms of the larva: olive,
greyish brown with a white stripe; green with a yellow stripe. All the prolegs
have expanded plantae to give them a T-shape, and, of the abdominal ones, those
on A4 are moderately reduced and those on A3 strongly so.
The host
plants listed by Robinson et al. (2001)
are all from the Sapindaceae: Dimocarpus, Litchi,
Nephelium.
However, there is also a record from Euphorbia (Euphorbiaceae) in Hong Kong (unpublished IIE
records).
