5b composite leaf case => 6
6a case rather slender, rear end bent downwards: Coleophora ballotella
6b case squat, straight: Coleophora mareki
7a mine upper- or lower-surface, greenish when lighted from behind; larva a maggot => 8
7b mine full depth, whitish when held against the light; larva with recognisable head => 10
8a blotch. prededed by a long, slender corridor (may be obliterated by the later blotch, but usually still visibile then in the frass pattern, when lighted from behind): Amauromyza labiatarum
8b corridor from start to end => 9
9a mine pinnately branched, the main branch overlying the midrib; frass in strings: Liriomyza strrigata

12a transparant blotch; most frass deposited in the centre of the mine: Dibolia depressiuscula
12b gallery: Apteropeda globosa & orbiculata

13b pinacula black => 14
14a larva: behind/below the anus a chitinous comb: Cnephasia asseclana
14b anal comb absent: Cnephasia stephensiana
