2a corridor ends upon a thick vein; from there the larva continues as a borer => 3
2b corridor not ending upon a vein => 4
3a larva a maggot: Phytomyza rufipes
3b larva with chitinised head: Ceutorhynchus pallidactylus
4a corridor pinnately branched, main branch overlying the midrib: Liriomyza strigata
4b corridor not pinnate, not associated with the midrib => 5
5a mine full depth; larva with chitinised head => 6
5b mine upper- or lower-surface; larva a maggot => 7
6a mine < 1 cm; larva, with thoracic feet, later lives free: Plutella xylostella
6b mine > 1 cm; larva, without thoracic feet, remains in the mine until close to pupation: Ceutorhynchus minutus
7a frass in discrete grains; puparium in the mine in a, usually lower-surface, pupal chamber: Chromatomyia horticola
7b frass, at least partly, in strings; pupation outside the mine: Liriomyza bryoniae
8a a blotch overlying the midrib, initially elliptic, later widening => 9
8b no association with the midrib => 10
9a frass powdery, in blackish-green clouds: Scaptomyza flava
9b frass partly in black strings: Liriomyza xanthocera
10a mine < 1 cm; larva with thoracic and abdominal feet, lives later free: Plutella xylostella
10b mine > 1 cm; larva with thoracic feet only, remains in the mine until close to pupation: Phyllotreta nemorum
Not included in the key: Aulagromyza mamonowi.
