The wingspan is 6.5-8 mm. The forewings are grey, between the fold and inner margin ochreous, and lighter grey along costa. There are W-shaped markings which are darkest along the fold and a dark dot at the end of the cell with a short dark streak which extends towards the apex. Adults have been recorded on wing in June and July.
The host plant is unknown, but might be a Tamarix species.
