The length of the forewings is 5.6–6 mm (0.22–0.24 in). The forewings are uniform lustrous, brownish grey, with scattered ochreous scales and a weak indication of two linear rust coloured stigmata in the cell. The hindwings are pale grey.[3]

The larvae feed on Atriplex portulacoides and Atriplex halimus. They mine the leaves of their host plant. The mine is blotchlike and most frass is ejected through a small opening in the mine. Larvae may leave the mine and restart elsewhere. Pupation takes place outside of the mine. The larvae are yellowish grey with three reddish brown length lines and a light brown head.
