Leaf-mine: A mine with several creases in lower epidermis. On thinner leaves, such as crab-apple, the upper surface may be arched to form a tube (British leafminers).

Lower surface tentiform mine with a yellow-green epidermis that has a few folds. Pupation within the mine. The pupa is amber or chestnut brown, and lies in a white cocoon. Generally the frass is accumulated in a corner of the mine, but sometimes a small quantity is incorporated in the wall of the cocoon (Bladmineerders van Europa).

Larva: Details unknown.

Pupa: The pupa is illustrated in Bladmineerders van Europa.

Adult: The adult is illustrated in UKMoths. The male genitalia, but not the female genitalia (check for update) are illustrated by the Lepidoptera Dissection Group.

Comments: Records in literature from other plant genera, such as Amelanchier, Cotoneaster, Crataegus or Mespilus germanica are either dubious or concern exceptional observations (Triberti, 2007a) (Bladmineerders van Europa).

Hosts elsewhere:
