The forewings are grey with a large prominent buff patch at the apex. As the thoracic hair is also buff, the moth resembles a broken twig when at rest. The hindwings are creamy-white. This moth flies at night in June and July and sometimes comes to light, although it is not generally strongly attracted. 1. \n* The flight season refers to the British Isles. This may vary in other parts of the range.
