  Pseudothyris sepulchralis, the mournful thyris, is a species of day-flying moth in the family Thyrididae and can be found throughout North America. They have a flight duration of 2–3 weeks. The adults are rarely found on flowering plants for feeding.
  
  ## Description
  
  The larva is about 18 millimetres (0.71 in) in length. As an adult, its wingspan is around 15–23 millimetres (0.59–0.91 in) and its body is black with white spots and marks.
  
  The larvae feed on Smilax species.
  
  ### Pupae
  
  The larva cuts an almost perfect circle into a leaf, before rolling itself in it, creating a pouch shaped cocoon and hibernating in it until the following year.
