The forewings are dark purplish-brown, streaked and flecked with white and ocherous especially. A streak extends from the base nearly to the apex, just within the costal margin of which the prevailing hue is ocherous, mixed with white. A white costal spot at the beginning of the costal cilia, and an opposite dorsal one, both small. The hindwings are pale ocherous-brown.

The larvae feed on the leaves of Robinia pseudacacia. They have been observed feeding within the mines of Macrosaccus robiniella, but also feed externally.[3] Young larvae are green with darker green longitudinal markings and a shining black head. Older larvae are pale brown with two dark brown longitudinal stripes and a row of dark brown spots.[4]
