ID pointers: Highly variable, a high proportion are blackish melanic forms and obscurely marked. Bright individuals can show a large white cross band on trailing edge  bordered by a solid black bar. Because this species, along with Rufous and Tawny Marbled Minors, are so difficult to separate, conclusive ID can only be determined by examination of the genitalia. However there are features across the three species that can act as a guideline. In general Marbled is generally larger with an angular forewing shape and typically has the most contrasting black and white forewing pattern.
