It may resemble several of the other Incurvaria species, but differs from these in that the wings are somewhat narrower, the colour paler and the pale spots at the trailing edge of the forewing less distinct.

The head is covered with long, erect, yellowish hair-like scales, and appears rather disheveled.

The larva is whitish with a yellowish-brown head and greyish-brown dorsal plates on the three leading body joints.

Forewings shining prismatic fuscous; a yellow-whitish dorsal spot before middle, and an indistinct dot before tornus.
