2a mine large, very transparent, not associated with the midrib => 3
2b mine smaller, brownish-opaque, often following the midrib or in a vein axil: Scrobipalpa costella
3a larva with red length lines: Phthorimaea operculella
3b larva pale yellowish green => 4
4a on Solanum dulcamara: Acrolepia autumnitella
4b on other Solanum species: Tuta absoluta
5a blotch mine => 6
5b corridor mine => 7
6a clutch size about 5: Pegomya hyoscyami
6b clutch about 11: Pegomya dulcamarae
7a frass in discrete grains; puparium in the mine, in a, usually lower-surface, pupal chamber: Chromatomyia horticola
7b frass in strings or pearl chains; pupation outside the mine => 8
8a upper-surface pinnately branched corridor, main branches overlying the major veins: Liriomyza strigata
8b corridor not pinnate and upper-surace at the same time; mostly in greenhouses => 9 **
9a larva: rear spiraculum wit 3 papillae => 10
9brear spiraculum wit ≥ 6 papillae => 11
10a corridor contorted, almost a secondary blotch: Liriomyza trifolii
10b corridor winds loosely through the blade: Liriomyza sativae
11a mine mostly in the basal part of the leaf, often in contact with the midrib, frequently between two veins; usually beginning upper-surface, becoming lower-surface further on: Liriomyza huidobrensis
11b mine randomly positioned, often crossing a vein; usually initially lower-surface, but upper-surface in the end: Liriomyza bryoniae
Not included in the key: Keiferia lycopersicella; Scrobipalpa ergasima.
** for a positive identification of these four, often very noxious species, rearing or molecular techniques may be necessary.
