Identification
Distinguished from other Aristotelia by the specific arrangement of white fasciae and metallic silvery-bluish iridescent on the forewings. The combination of an oblique white fascia from the wing base, a middle costal white dash, and a larger white dash at the costal cilia—each continued by metallic scales—is diagnostic. The small size (10.5-11.5 mm wingspan) and western North American distribution further aid identification. Similar species in the may share general pattern elements but differ in the number, position, and extent of white markings and metallic scaling.
