The Baronet is a reddish-yellow nymphalid butterfly with a fringe of black and white scales alternating along the edge of both wings, giving the margin a checkered look at rest.

It favours disturbed patches within forest at low elevation, where caterpillars feed on Diospyros and Shorea trees, and adults are usually seen settled on foliage rather than visiting open flowers.
