Calletaera postvittata (Java)

This species is similar in facies to subgravata Prout but smaller, usually lacking a hindwing discal spot and having the hindwing postmedial distinctly dark brown and broadening gradually towards the dorsum. The general coloration is more beige. The male genitalia have more massive ornamentation of the aedeagus and a straight, rather than angled, ventral arm to the valve.

Geographical range. Indian Subregion, Taiwan, Sundaland.

Habitat preference. The type is from Sarawak, but no recent material has been located. Sumatran material is from the lowlands.

Biology. The larva was described by Bell (MS). It is of typical geometrid form. The head is dirty yellowish white, suffused and spotted with pinkish brown. The body is dull, more or less smooth, a delicate light grass green that is lined or banded longitudinally with broken whitish lines bordered with pinkish brown; the green is obscured by such lines everywhere except around each spiracle and in the subspiracular region.

The young larvae are very thin, active, living on the undersides of leaves. The mature larva lives stretched along twigs or branches, often subtending the angle formed by a petiole and twig, well camouflaged. The larvae may feed and rest along the edges of leaves in intermediate stages. Young leaves are favoured for feeding. Pupation is in a light cocoon incorporating particles of substrate in a crevice or on the ground.

The host-plant is Memecylon (Melastomataceae).
