The first joint of the antennae is greatly expanded and forms a white "eyelid" over the facets, otherwise the antennae are brownish and about 4/5 as long as the forewing. The head, forebody and forewing are white, the hind body greyish-brown, the hind wing light brown. Meyrick-The forewings are white with an oblique rather dark fuscous streak from middle of costa, and another from middle of dorsum. A fuscous ill-defined subapical fascia is followed by two darker costal strigulae and there is a minute black apical dot. Hindwings fuscous.
The moths fly from June to July depending on the location.
