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 :
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. It is brown with a yellow arc or series of blotches on each hind wing.
Underneath, the forewings are brown with two yellow marks on the costa of each forewing, and orange under each hindwing with a dark mark at the tornus.
The eggs are laid singly, on the underside of young foodplant leaves, often near the central vein.
The species is known across south-east Asia, including
and has recently been reported Central America and Africa, including :
The species appears to migrate with the Monsoon winds. Efforts are being made to control the pest using :
although these may be of little value given the migratory behaviour of the moths.
