This is a smaller moth than the preceding and is a leafroller on various grasses. We reared it from Panicum barbinode , Paspalum conjugatum , and Oplismenus compositus . This moth also has a wide distribution in the tropics: Africa, Asia, Japan, Borneo, Australia, Solomons, Fiji, Samoa, Society Islands, and Austral Islands, but not in Hawaii. Its work on grass was noted in 1911 by Fullaway , but its name was not determined .
