2a mine full depth; larva with thoracic feet and chitinised head => 3
2b mine upper- or lower-surface; larva a maggot => 7
3a mines small and of indefinite shape; older larvae live free among spun leaves => 4
3b mine not unusually small, a gallery or bloch, or larvae feeding from a silken tube => 6
4a larva: pinacula colourless (the bases of the setae themselves are black) : Cnephasia incertana
4b pinacula black => 5
5a larva: behind/below the anus a chitinous comb: Cnephasia asseclana
5b anal comb absent: Cnephasia stephensiana
6a initially a hair-thin corridor along the leaf margin; later full depth blotches are made from the leaf margin: Bucculatrix cristatella
6b larva makes blotch mines from a silken tube, covered with sand grains: Scrobipalpula psilella
7a short gallery that seems to end upon a thick vein: Ophiomyia curvipalpis
7b not so => 8
8a secondary feeding lines conspicuous: Trypeta zoe
8b no secondary feeding lines => 9
9a frass in discrete grains; pupation in the mine, in a, usually lower-surface, pupal chamber: Chromatomyia cf. syngenesiae
9b prior to pupation the larva leaves the mine through a semicircular exit slit; frass at least partly in strings => 10
10a mine extends from the leaf basis; frass in strings; larva: rear spiraculum with met 9-13 papillae: Liriomyza strigata
10b mine extends from the leaf tip; frass in pearl chains and discrete grains; rear spiraculum with 18-20 papillae: Phytomyza pullula
10c“small brown mine” in Anthemis tinctoria; rear spiraculum with 6-9 papillae: Liriomyza centaureae
10d frass in strings; rear spiraculum with 3 papillae: Liriomyza ptarmicae
Not included in the key: Scrobipalpa montella (mine not described).
