Diagnosis

See the previous species.

Taxonomic Notes

Bornean material may represent a distinct race as the forewing fasciae are weaker, more broken. However, the male genitalia are identical with those of typical pustulata from Peninsular Malaysia.

Geographical Range

Sundaland.

Habitat Preference

Generally distributed in lowland forest, the species is rarer than insularis. It has been taken as high as 1618m on Bukit Retak, Brunei.

Biology

The species has been reared by Chey Vun Khen and staff at the Forest Research Centre, Sepilok. The larva is robust, coarsely mottled pale green (more bluish grey-green in earlier instars). The spiracles are orange. There are irregular, small, black markings across the dorsum on A8. The head is rugose, dull rufous orange, marked centrally with a darker brown, inverted ‘V’. The host-plant was Acacia mangium, and the species has been reared also from Gliricidia (both Leguminosae) in Sabah.
