Ypthima impura, the impure ringlet (known in Afrikaans as the vuil-ringetjie), is a butterfly of the family Nymphalidae. It is found in most of Sub-Saharan Africa.

Adults are on wing year round with peak in early summer and autumn in southern Africa. [3] The butterfly usually has three ocelli on the underside of their hindwing, although these may not appear during the dry season. [4]

The larvae feed on Poaceae grasses. Larvae have also been reared on Ehrharta erecta . [5] Females are usually more sedentary than males, with stouter abdomens. [6]
