Dichotomous table for leafminers

1a larva mines from a case, and makes fleck mines => 2

1b the larva does not mine from a case => 3

1c galls, etc => Tables for all parasites per species

2a mouth angle 90°, making the case standing perpendicularly on the leaf: Coleophora saturatella

2b mouth angle c. 45°, case standing obliquely on the leaf: Coleophora trifariella

3a the mine contains (almost) no frass => 4

3b clear amounts of frass in the mine => 5

4a the larve lives in the mine, and ejects almost all frass: Micrurapteryx kollariella

4b the larva does not live in the mine (but rather between two leaves sandwiched upon each other) and mines from the outside: Mirificarma cytisella

5a tentiform mine: Phyllonorycter staintoniella

5b flat blotch mine: Leucoptera heringiella

Not included in the key: Oryxolaemus flavifemoratus; Phytoliriomyza variegata (improbable).
