The Caterpillars of this species are brown with a pair of narrow yellow lines along each side enclosing a dark brown band. The caterpillar is a pest overseas on :
and they also feed on other trees such as:
The eggs are laid on the undersides of the leaves. The caterpillar cuts a semicircular piece of leaf and folds or rolls it over to form a shelter. The mature Caterpillar often lives in this shelter by day, and feeds nocturnally.
The adult moth has a wing span of about 4 cms. The forewings are a variable blotchy brown, sometimes with a dark spot near the middle. The hindwings are brown, each with several yellow spots.
Underneath, the forewings are brown with two yellow marks on the costa under each forewing, and orange under each hindwing with a dark mark under the tornus.
The eggs are laid singly, on the underside of young foodplant leaves, often near the central vein.
The species is endemic across south-east Asia, including
The species appears to migrate with the Monsoon winds. It has recently been reported Central America and Africa, including :
It also occurs in Australia in
Efforts are being made to control the pest using :
although these may be of little value given the migratory behaviour of the moths.
