2a mine very small; older larvae live free among spun leaves => 3
2b mine of normal size; older larve either in a leaf roll, or mining all its life => 4
3a pinacula colourless (but the bases of the setae are black): Cnephasia incertana
3b pinacula black: Cnephasia asseclana
4a elongated blotch; only in spring, on Campanula persicifolia: Orophia ferrugella
4b mine, at least its first part, a definite corridor: Orthochaetes insignis
5a narrow corridor, descending to the petiole, then to the bark of the stem: Ophiomyia eucodonus
5b mine larger, not leaving the lea => 6
6a pupation in the mine in a, usually lower-surface, pupal chamber: Chromatomyia horticola
6b pupation outside the mine => 7
7a branching corridor, positioned over the midrib and the more heavy lateral veins: Liriomyza strigata
7b no association with the leaf venation => 8
8a upper surface blotch, preceded by a short, narrow corridor; larvae usually communal: Amauromyza gyrans
8b corridor; larva solitary => 9
9a corridor shallow, whitish; frass in discrete grains: Phytomyza campanulae
9b corridor deeper, greenish; frass in the first section of the mine in pearl chains: Phytomyza rapunculi
Not included ih the key: Ophiomyia versera.
