Because wind tends to focus the floating leaf cases, hurt usually happens in patches ( Fig. five ). A youthful, vigorously expanding crop can usually recuperate from high ranges of defoliation. The moths are vibrant white with mild brown and black spots (Fig. six ). The rice caseworm is usually perplexed with its seem-alike relative Parapoynx fluctuosalis (Zeller). which does not feed on rice (Fig. seven ). Instead its larvae feed on an aquatic weed Hydrilla.

Moths are lively at evening but continue to be sheltered in the crop foliage in the course of the working day keeping absent from fowl and dragonfly predators. When disturbed, the caseworm moths fly limited distances and alight in the rice cover. Eggs are laid on the beneath surfaces of leaves drooping into the h2o. The pale, yellowish environmentally friendly eggs are laid in one particular or two prolonged rows ( Fig. 8 ).
