Dichotomous table for leafminers
1a corridor or blotch => 2
1b fleck mine => 13
1c galls, etc => Tables for all parasites per species
2a mine full depth; larva with chitinised head => 3

3a the larvae mine only briefly, later they live free among spun plant parts => 4
3b the larve mine till shortly before pupation => 8
4a the mines contain silk => 5
4b no silk in the mine => 6
5a larva: behind/below the anus a chitinous comb: Cnephasia asseclana
5b anal comb absent: Cnephasia stephensiana
6a larva whitish, with several reddish length lines e wittig, een aantal roodachtige lengetelijnen: Syncopacma cincticulella
