Dichotomous table for leafminers
1a blotch, no trace of a preceding corridor => 2
1b corridor, may widen into a blotch => 6

Dichotomous table for leafminers
1a blotch, no trace of a preceding corridor => 2
1b corridor, may widen into a blotch => 6
1c fleck mine; larva in a lobe case => 15
1d galls, etc. => Tables for all parasites per species
2a the blotch soons turns into an elliptic excision: Incurvaria praelatella
2b no excision is made => 3
3a mine tiny; larva yolk-yellow: Spialia sertorius
3b mine larger; larva not yellow => 4
4a on the oviposition spot, usually near the leaf margin, a shining black drop of dried secretion: Trachys fragariae
4b no such drop => 5
5a larva: no claw at the end of the feet; common species: Fenella nigrita
5b the feet end in a distinct claw; only known from Hungary on P. cinerea: Fenella arenariae
6a mine begins at a globular, shining egg shell => 7
6b no egg shell visible => 13
7a mine begins with a strongly contorted corridor: Ectoedemia arcuatella
7b initial corridor not contorted => 8
8a mine remains a gallery till the end => 9
8b gallery widens into an irregular, often large, blotch => 11
9a egg at the underside of the leaf: Stigmella thuringiaca
9b egg at the upperside (rarely underside, but the gallery then very slender) => 10
10a frass in the first section of the gallery diffuse, greyish green: Stigmella anomalella
10b frass black and granular, also in the first section: Stigmella splendidissimella
11a egg at the upperside: Stigmella poterii
11b egg at the underside => 12
12a lowland species: Stigmella aeneofasciella
12b always, or almost always, high in the mountains: Stigmella stelviana (always) & Stigmella tormentillella (almost always)
13a initial corridor short, quickly widening; mine full depth; larva with chitinised head => 5
13b initial corridor longer and/or widening more slowly; mine upper- or lower-surface; larva a maggot => 14
14a frass in the corridor part in two rows of grains; larva: rear spiraculum with 3 papillae: Agromyza idaeiana
14b initial corridor almost full of frass; rear spiraculum with 6 papillae: Agromyza sulfuriceps
15a case helicoidal; opening of the mine not neatly circular: Apterona helicoidella
15b case more or less straight; opening a perfect circle => 16
16a spatulate leaf case: Coleophora albicostella
16b lobe case => 17
17a case brown; lobes of the case cut out of the upper epidermis; mouth angle 0°-10°: Coleophora violacea
17b case whitish; lobes cut out of the lower epidermis; mouth angle 20°-30°: Coleophora potentillae
Not included in the key: Coleophora ahenella, sergiella, vitisella; Sophronia humerella; Tinagma perdicella.
