Leaf-mine: An initially linear mine, which at second instar develops into a large whitish blotch with conspicuous black frass. The early linear mine is frequently entirely enveloped by the blotch but is detectable by the alternate irregular strips of frass. Pupation external (Spencer, 1976: 158). The mine is illustrated in British leafminers and Nederlandse bladmineerders.
