1c larva lives in a transportable case, makes fleck mines => 2
1a larva not only mines the leaves but also bores in the stem, causing the top of the plant to wilt: Delia echinata
1b larva exclusively in the leaves => 3
1c galls, etc. => Tables for all parasites per species

2a mouth angle ± 90°, case stands perpendicular to the leaf: Coleophora saponariella
2b mouth angle ± 30°, case stands obliquely on the leaf: Coleophora nubivagella
3a frass sparingly, mostly in fine grains; mine a blotch, preceded by a short corridor (often overrun by the growing blotch); blotch without side branches: Amauromyza flavifrons
3b frass abundant, in strings or coarse grains; mine a corridor or a blotch with side branches => 4
4a primary blotch with side branches or lobes: Liriomyza xanthocera
4b corridor (rarely a secondary blotch) => 5
5a a pinnately branched corridor, its main axis overlying the midrib: Liriomyza strigata
5b corridor little branched, not pinnate, not associated with the midrib: Liriomyza bryoniae
Not included in the key: Scaptomyza graminum.
