The Impure Ringlet (''Ypthima impura'', known in Afrikaans as the ''Vuil-ringetjie'') is a butterfly of the Nymphalidae family. It is found in most of sub-Saharan Africa. The wingspan is 32–36 mm for males and 34–38 mm for females. Adults are on wing year round with peak in early summer and autumn in southern Africa.〔Woodhall, S. Field Guide to Butterflies of South Africa, Cape Town: Struik Publishers, 2005.〕 The butterfly usually has three ocelli on the underside of their hindwing, although these may not appear during the dry season.〔(Subtribe Ypthima )〕 The larvae feed on Poaceae grasses. Larvae have also been reared on ''Ehrharta erecta''.〔(Swaziland National Trust Commission )〕 Females are usually more sedentary than males, with stouter abdomens.〔Willis, C. and S. Woodhall.
