Leaf-mine: A large blotch, yellow or brown, preceded by a short corridor that in the end mostly is completely overrun. Generally several larvae share a mine. Especially in fresh mines the green primary and secondary feeding lines are well visible. Pupation outside the mine.

Hering (1957a) warns that the mines cannot be separated from those of the rare Cryptaciura rotundiventris (Bladmineerders van Europa).

Mine is deep and leads to a blotch, which is usually coloured yellow or brown (British leafminers).

Larva: Mandibles with two 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: 60). The puparium is illustrated in Bladmineerders van Europa.

Comments: Peucedanum ostruthium is treated as Imperatoria ostruthium (Masterwort) by Stace (2010).
