  The wingspan is 10–14 mm. The head is yellowish-white.

Hindwings are grey. The larva is dull whitish yellow; head and plate of 2 pale brown.
  
  Adults are on wing from May to July depending on the location.
  
  The larvae feed on Sorbus aucuparia and Malus species.
  
  The apple fruit moth, is seen to be a parasite for the apple growing communities in Finland, Norway, and Sweden. These moths are seed predators for the mountain-ash trees rowan. However, when there is a dip in the fruit produced by rowan every couple years in this region, the apple fruit moth finds a new host in the form of apples. Apples are not their desired host however and they communicate with the rowan seeds they prefer through odors.
