The wingspan is 5.5-6.4 mm. The forewings are dark brown with a faint golden luster. The markings are silvery with a golden and opalescent luster. The hindwings are brownish gray. Adults have been recorded on wing from June to July.
The larvae feed on Panicum species, including Panicum dichotomum and Panicum clandestinum. They mine the leaves of their host plant. The mine starts as a narrow thread. It then enlarges into a blotch with irregularly scattered frass.[2]
