Eudonia is a large and widespread genus in the grass moth family (Crambidae), subfamily Scopariinae. There is no common name for the roughly 250 species placed here; new species are still being described regularly. Although the genus was proposed early in the 19th century, many of these moths were for a long time retained in Scoparia, the type genus of the subfamily and a close relative of Eudonia. A few small genera have been proposed for separation from Eudonia, but given the size of this group this is not particularly convincing; thus, all are retained here pending a comprehensive phylogenetic review.
