Distinguished from similar Hedya by the combination of a square (not rounded) basal black spot and the broad white cross-band on the forewing. The white band has been likened to bird droppings, a possible form of protective mimicry. The light-grey cross-band between the basal spot and wing tip provides additional diagnostic separation from .
