17b mine contains obvious amounts of frass => 24
18a the larve lives in the mine till just before pupation; no silk on the plant in the vicinity of the mine: Micrurapteryx kollariella
18b the larvae live shorter or longer outside the mine, producing external silk => 19
19a the young larvae live in (small) mines; later they live free among spun leaves => 20
19b the larve live between leaves spun together, make holes in their epidermis and cause fleck mines (perhaps only facultative miners): Mirificarma cytisella; Syncopacma albipalpella, Syncopacma suecicella
20a larvae darkly coloured, greenish to greyish-black => 21
