Identification
The small size (17 mm wingspan) and bright orange coloration are distinctive features. Separation from other Schinia requires examination of genitalia or detailed wing pattern analysis. The two differ in wing margin characteristics: S. a. tenuimargo has a narrower wing margin than the nominate subspecies.
