Acrolophus popeanella is a in the Acrolophidae, commonly known as Clemens' Grass Tubeworm Moth. The was described by James Brackenridge Clemens in 1859. are small moths with distinctive dark brown wings marked with lighter brown blotches and a striped pattern near the forewing margins.

Identification
Distinguished from similar Acrolophus by the combination of dark brown wing ground color with lighter brown blotches and the striped pattern near the forewing margins.
