The wingspan is 33–38 mm. The forewings are bright yellow with two narrow brown fascia. The hindwings are cream coloured but are rarely seen due to the characteristic resting position (see spinach moth). The species flies at night from June to August and is attracted to light.

The larva feeds on bedstraw. The species overwinters as an egg.
