Habitat
The habitat consists of marshes and pondsides.Food
The larvae feed on ''Nelumbo lutea'' and ''Polygonum'' species. Young larvae attach themselves to the leaf by a thin silken strand. Full-grown larvae feed under a loose silk net, and roll the leaves. They then tunnel into the leaf petiole and form a burrow where pupation takes place. The larvae have a pale greenish-yellow body and a brownish head.References:
