The wingspan is 31–36 mm. The length of the forewings is 14–17 mm. Forewing greyish rufous, sometimes darkened with fuscous; lines and stigmata a little darker, often very obscure; hindwing orange yellow with a broad marginal black border; costal and inner margins, a submedian streak from base, and the cell blackish; fringe yellow.^[1]

The larvae feed on various grasses and herbaceous plants such as meadowsweet (Filipendula ulmaria) and common mallow (Malva sylvestris).^[2]
