This species' common name is usefully descriptive: The forewings are dark reddish-brown marked with a prominent light orange-brown stigma and a bright white subterminal line. The hindwings are grey, darker towards the termen. The wingspan is 34-44 mm. They are attracted to light, sugar and nectar-rich flowers.
The larva is green or brown with black and yellow stripes down the side. It feeds on a wide range of plants and is occasionally a pest of cultivated tomatoes. The species overwinters as a pupa.
