General Description
provided by University of Alberta Museums
A medium size moth (forewing length about 33 mm) with light and dark reddish brown forewings. The subterminal area in particular is usually lighter brown, and is crossed by poorly defined jagged light and dark lines. The orbicular and reniform spots are well defined, with the area before and between them blackish. The basal dash-claviform spot is prominent and filled with black scales. Hidwings brown. Very similar to and often confused with A. obliqua, which is slightly larger, darker, and less streaky appearing. Specimens of vancouverensis and obliqua are difficult to separate, and are frequently found misidentified in collections.
