The Grass Demon Caterpillar

It was a found on a Hedychium plant.

Soon after hatching, the caterpillar does not consume the eggshell completely and it makes itself a spacious cell and hides inside it. The caterpillar is sluggish and comes out to feed only at night. Even when disturbed it is reluctant to leave its cell.

The caterpillar is a light uniform leaf green color with a dark green pulsating line on the back and a relatively small, dark head. The full grown larva has the habit of resting with the first three segments contracted, so as to give a humped appearance. It always lies closely applied to the leaf, by turning over a triangular piece from the edge onto the upper surface over itself.
