It is commonly known as the acorn moth, but this can also refer to the tortrix moth Cydia splendana from Europe.

The wingspan is 15–25 mm. Adults have gray to grayish-brown forewings with a pale diffuse line bordered distally by dark band. There is also a black median dot and two black reniform dots, which form a triangle. The terminal line is composed of dark dots. The hindwings are shiny gray with dark veins and a fringe of long hair-like scales. They are on wing from April to September.

The larvae feed inside acorns and chestnuts.
