Leaf-miner: 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 pupariria cannot be distinguished from those of the very common Euleia heraclei (Bladmineerders van Europa).

Larva: The larvae of flies are leg-less maggots without a head capsule (see examples). They never have thoracic or abdominal legs. They do not have chewing mouthparts, although they do have a characteristic cephalo-pharyngeal skeleton (see examples), usually visible internally through the body wall.

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

Puparium: The puparia of flies are formed within the hardened last larval skin or puparium and as a result sheaths enclosing head appendages, wings and legs are not visible externally (see examples).

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).
