Overwinters as an adult. They are attracted to light and to sugar and may be seen on Ivy blossom in the autumn or Sallow catkins in spring.
Note can be confused with the Chestnut but that species is generally paler and with a more rounded wing tip. In Dark Chestnut the wing tip is somewhat hooked, but difficult to see that on worn specimens.
