Cydia deshaisiana or jumping bean moth is a moth from Mexico that is most widely known as its larva, where it inhabits the carpels of seeds from several species of the shrub genus Sebastiania (S. pavoniana or S. palmeri). These seeds are commonly known as Mexican jumping beans. The larva may live for months inside the bean with varying periods of dormancy.It eats away the inside of the bean, making a hollow for itself. If the seed is cut, the larva will repair the hole with silk. The small, jawless silver and gray-colored moth will live for only a few days.
