Diagnosis. The unusual wing shape and lineated grey facies are unmistakable.
range. Oriental tropics to Sulawesi.
Habitat preference. The species is uncommon, all recent material being
taken in lowland alluvial forest regenerating on abandoned farmland near Long
Melinau during the Mulu survey.
Biology. Bell (MS) observed the biology in S. India. The larva is fusiform, the
head heart-shaped, but rather square. The colour is green, with thick dorsal,
and dorsolateral to spiracular, longitudinal white bands. The tubercles of the
setae are black, sometimes tinged violet. The anterior hairs of T1 are yellow.
The pupa is stout, boat-shaped, the cremaster triangular with a stout shaft
bifid at the extremity.
The larvae live on the undersides of leaves, stretched out, though with
the thoracic segments contracted. They fall to the ground on a silken thread
when disturbed. Pupation is in a slight silken cocoon with particles, either
near the ground or in a rolled leaf.
The host-plants are Bajanella and other Bignoniaceae.
