The wingspan is 28–36 mm. The ground colour of the forewings is greyish green, with a reddish tinge. The central band is dark and may be replaced by dark wavy crosslines. The forewings have a pointed shape. This is a very variable species. The larva is very long and slender, the thorax slightly less thin, the anal points well developed. It is green, the thorax with a red dorsal line, abdomen with a red dorsal spot on each segment, the legs and anal points tipped with red. The pupa is slender, yellow-brown with a delicate purple bloom, dotted with black; cremaster darker.[1][2]
Similar species: Adults are similar in appearance to the autumn green carpet (Chloroclysta miata) but C. miata has a pale central band, grey hindwings and no red tinge.
