The forewing is elongate and the ground colour is golden ochreous with some white scales at the base. The hindwings are pale greyish and slightly shiny. Adults are on wing from early January to mid-March and from early June to mid-August. The larvae feed on Eriosema psoraleoides, Rhynchosia confusa and Rhynchosia nitens.
