The wingspan is about 5 mm.[3] Adults are brilliantly shiny with an orange forewing marked with transverse silvery-white bands that are narrowly edged with black along their basal margins.[4]

The larvae feed on Robinia species, including Robinia hispida, Robinia neomexicana, Robinia pseudacacia and Robinia viscosa. They mine the leaves of their host plant. The mine has the form of a yellowish blotch mine. The mine usually occurs on the upperside, but occasionally on the underside, of the leaflet. It is nearly circular in its early stages, but later in development, it becomes irregular in shape.
