features
butterfly
Both sexes of Vanessa myrinna look the same. The moths have a wingspan of 56 to 60 mm and an orange-brown basic color with black spots. The apex (wing tip) of the forewings is black with white spots. In the submarginal zone of the upper side of the hind wing there is a broad, dark brown band without eye spots, which clearly distinguishes it from other species of its genus.
Aberration elymi
A rare aberration elymi is known that also occurs in other species of the genus Vanessa . This lacks the discal wing drawing, the subapical dark elements merge and it shows a row with white, submarginal spots. This aberration is likely caused by the cold during the pupal phase. She was starting as Pyrameis myrinna . eunice Hall , 1917.
