Taxonomic notes. Sundanian material (except Javan - ssp. stigmatica Rothschild) is
referable to ssp. strigivenata Butler: the hindwing marginal markings are
much larger than in the typical Sri Lankan and Indian race, though this is
Geographical range. Sri Lanka and India to Sundaland.
Habitat preference. This is a rare species but taken both in lowland
forest and in upper montane forest.
Biology. Bell (MS) reared the larva in S. India. The colour is a light chocolate
brown, satiny, with a black collar on the prothorax, and other segments variably
marked with black lines: dorsally at the anterior end; obliquely laterally on Al
and A7; and Al0 dorsally. Younger larvae are more brightly marked. The larva is
reclusive, feeding up slowly on young leaves. Pupation is in a semiovoid cocoon
on the soil or rotten wood.
