Leaf-mine: A large blotch, yellow or brown, preceded by a short, in the end mostly unrecognisable corridor. Generally several larvae in the mine. Especially in fresh mines the green primary and feeding lines area well marked. Pupation outside the mine. Mines and puparia cannot be distinguished from those of the very common Euleia heraclei (Bladmineerders van Europa).

Larva: Posterior spiracules each with three bulbs; mandibles with two large teeth (Bladmineerders van Europa).

Puparium: Yellow; anterior spiracle openings arranged in large arcs, not elevated on a fan-like structure; posterior spiracles each with a central opening of similar size to the lateral openings (White, 1988).

Comments: Records on Arctium and Heracleum [Asteraceae] require confirmation (White, 1988).
