Diagnosis.
The contrasting black and grey forewings have a striking pattern somewhat like
that of the Bornean Anoba species, but in these it is more of a greenish brown, clearly
defined and somewhat archipelagic, with the dark bands broken by pale lines on
the veins. The distal margin in divulsa is
distinctly angled obtusely at the centre. The male antennae are serrate and
strongly fasciculate.
Geographical
range. Indian Subregion, Burma, Thailand (VK), Andamans, Borneo,
Sulawesi.
Habitat
preference. The species is uncommon in lowland forest, not recorded above
200m, and has also been taken in disturbed coastal forest.
Biology.
Bell (MS) reared the larva in India. It is cylindrical, with the prolegs on A3
absent and those on A4 half-size, compared by Bell to seal's flippers, often
held back against the ventrum. A8 is slightly tumid dorsally. The head is dark
rusty brown, mottled with green. The body is a light, ochraceous olive-green,
suffused with smoky brown everywhere except ventrally. There is a well-defined
subspiracular white band, slightly tinged yellow at each end.
The
larvae live singly under leaves, eating from the edges. Pupation is in a cell of
leaves lightly joined with silk. The pupa has no bloom. There is a high level of
parasitism by Diptera.
The host
plants recorded were Dalbergia and Pterocarpus (Leguminosae).
