2a mine in the end a large blotch; larvae mine all their life => 3
2b mine small, very irregular; older larvae live free, among spun leaves => 4
3a mine contains no frass: Micrurapteryx kollariella
3b mine contains much frass: green at first, then black, in concentric arcs: Leucoptera laburnella
4a larva: pinacula colourless (but the base of the setae themselves black): Cnephsia incertana
4b pinacula black => 5
5a larva: below/behind the anus a chitinous comb: Cnephasia asseclana
5b no anal comb present: Cnephasia stephensiana
6a corridor that more or less closely follows the leaf margin until the leaf tip, then suddenly widens into a blotch (unusual species on this hostplant) => 7
6b mine not hook-like => 8
7a corridor very closely following the leaf margin; secondary feeding lines conspicuous: Agromyza demeijerei
7b corridor loosely following the leaf margin; no secondary feeding lines apparent: Agromyza johannae
8a corridor from start to end => 9
8b corridor, widening into a blotch => 12
9a puparium in the mine, in a, usually lower-surface, pupal chamber: Chromatomyia horticola
9b larva leaves the mine before pupation through a semicircular exit slit => 10
10a corridor pinnately branched, main branch overlying the midrib: Liriomyza strigata
10b corridor little branched, not associated with the midrib => 11
11a frass in two rows of grains or strings: Lyriomyza bryoniae
11b frass in a broad green central band: Liriomyza congesta
12a frass powdery, in green clouds along the margins of the mine: Scaptomyza graminum
12b frass in big black grains, partly hanging together in pearl chains: Liriomyza xanthocera
