Identification
The combination of small size (14 mm wingspan), dark purplish-black forewings with satin lustre, and presence of bluish-white microscales visible under magnification distinguishes this from many . The variable pale forewing markings—when present—provide additional diagnostic characters. The strong purple reflections on the hindwings are notable.
