Melete lycimnia, the common melwhite, primrose flag or lycimnia white flag, is a butterfly in the Pieridae family. It is found from Texas in the United States to Bolivia. The habitat consists of lowland rainforests. The wingspan is 52–56 mm (2.0–2.2 in). The appearance of the adults depends on the subspecies and ranges from a white ground colour, narrow black borders, and a yellow spot at the base of the hindwings (M. l. peruviana) to primrose yellow, with wide brown borders (M. l. lycimnia). In all subspecies, females are more yellowish. The larvae probably feed on Loranthaceae species.
