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.
