Leaf-mine: The larva feeds on hazel or hornbeam, creating blotches with intertwining threads of frass, typical of the genus (UKMoths).

Large white blotch, starting at the leaf margin. Frass in long threads. Often several larvae in a mine. Pupation outside the mine (Bladmineerders van Europa).

The mine is also illustrated in British leafminers.

Larva: White with a pale brown head; a pair of brown spots on the pronotum (Bladmineerders van Europa).

Pupa: Details unknown.

Adult: The adult is illustrated in UKMoths by Rob Edmunds (as Eriocrania chrysolepidella). The genitalia are not illustrated by the Lepidoptera Dissection Group (check for update).
