Diagnosis. This is one of the smaller Bornean species, all of which have a paler,
more variegated upperside: the wings below are strongly fasciated with black,
the postmedials in the male having components elongated into striae. The
submarginals below are more continuous, enclosing the postmedial spots: in the
other smaller species the submarginals are more broken.
Dissection of male and female genitalia is recommended: the male has a
rather ovate, uniformly setose valve, the female a sclerotised patch basal in
the bursa additional to the signum which is broad, rather than a narrow band.
Geographical range. Indo-Australian tropics from the Indian Subregion to
Queensland and New Caledonia.
Habitat preference. Only one Bornean specimen has been located, from near
Pontianak in Kalimantan. No altitude data are given.
Biology. Bell (MS) described the biology in S. India. The eggs are laid singly on
the leaves, twigs and axils of the host-plant, and the young larvae prefer to
feed on young leaves.
The larva is cylindrical, narrowing slightly at each end. The head is
very slightly and broadly bilobed, wider than T1, and yellow-green in colour.
The body is a rosy pinkish green, variable in shade, with a white, longitudinal
dorsolateral line and a pale band in the spiracular region.
Young larvae sit on the edges of leaves in a variety of postures, older
ones being more on the underside and eating holes in the lamina. The pupa is
formed in a slight silken cell in a rolled leaf edge.
The host-plants recorded were Ardisia and Embelia (Myrsinaceae).
