1a corridor < 1 cm long, full depth; larva, with feet and chitinised head, later lives free => 2
1b corridor > 1 cm, upper-surface; larva, a maggot, until pupation in the mine => 7

2a some silk is deposited in the mine, causing some contraction; larval dark => 3
2b no silk in the min that remains completely flat; larval (apart from pinacula) light in colour => 4
3a larva: pinacula colourless (the bases of the setae themselves are black) : Cnephasia incertana
3b pinacula black: Cnephasia asseclana
4a larva: with three dark,length lines => 5
4b no, or just one dark length line => 6
5a prothoracal plate shining black; first pair of thoral feet black: Agonopterix purpurea
5b prothoracal plate not entirely black; first pair of thoracic feet yellowish green: Agonopterix rotundella
6a larva: head light brown: Epermenia chaerophyllella
6b head black: Epermenia aequidentellus
7a mine entirely within the leaf => 8
7b mine runs toward a thick vein; from there the larva descends through the petiole into the root: Napomyza carotae
8a puparium formed inside the mine: Chromatomyia horticola
8b larva leaves the mine prior to pupation => 9
9a larva with frontal appendage => 10
9b no frontal appendage => 11
10a mine a gallery (very common species): Phytomyza chaerophylli
10b blotch mine (occurence on this host probably xenophagy): Phytomyza heracleana
11a larva: anterior spiraculum fist-shaped; fress partly in pearl strings; Central European species: Phytomyza mylini
11b anterior spiraculum with 1-12 papillae; frass in discrete grains; Mediterranean species: Phytomyza ferulae
Not included in the key: Liriomyza trifolii.
