Leaf-mine: Young larvae make small, full depth blotch mines, almost without frass. Older larva live externally on the plant under a light web (Bladmineerders van Europa).

Initially forms a small blotch mine and may later feed in a slight web. In coastal areas may continue mining throughout the larval stage (British leafminers).

Larva: Head black; pothoracic shield also, divided by a light line. Body translucent yellow-green with a darker dorsal line and black or brown spots. The black head distinguishes the larvae from those of E. chaerophyllella (see Hering, 1957a) (Bladmineerders van Europa). The larvae are also described by Sterling (2004).

Pupa: Details unknown.

Adult: The adult is illustrated in UKMoths. The male and female genitalia are illustrated by the Lepidoptera Dissection Group.
