This pest damages banana and plantain crops. Adults are butterflies and moths with sizes ranging from 8 to 10 cm. The forewings are dark brown, with a white or yellow band near the wingtip, and two small white spots. Hind wings are dark brown with reddish tones.
Male Opsiphanes show two hairy tufts, not so females. Spots on the ventral section resemble eyes. Adults spend the day on rejected fruit or rotting bunches feeding on their sugary substances
Larvae look for dry places to form chrysalis, which are kidney-shaped and yellowish-green when recently formed, and turn light brown shortly before the butterfly emerges. They also show a small silver area on the sides, near the end of the body.
When 5 to 8 larvae appear in the middle third of the leaves, or when more, then 20% of the leaf surface has been eaten.
The vast majority of the bananas currently grown and consumed were not conventionally bred but are selections made over probably thousands of years from naturally occurring hybrids. Cultivated bananas are very nearly sterile and as a consequence are not propagated from seed but rather through vegetative propagation, primarily suckers as well as more recently micropropagated or tissue cultured bananas. These factors, very old selections, near sterility and vegetative propagation, mean that these bananas have not been genetically improved either for resistance or improved quality and are becoming increasing in affected by serious pests and diseases.
