1a mine in fallen leaves: Neocoenorrhinus pauxillus
1b fleck mine => 2
1c blotch, without a trace of a preceding corridor => 4
1d corridor, may be widened at the end => 5
1d tentiform mine => 12
1e galls, etc => Tables for all parasites per species
2a case ≥ 8 mm long; almost perpendicular to the leaf surface: Coleophora hemerobiella
2b case ≤ 6 mm, obliquely on the leaf => 3
3a case yelowish to greyish, very common throughout Europe: Coleophora serratella
3b case blackish, the end reddish; species of central and outheastern Europe: Coleophora kroneella
4a mine small, pear-shaped, especially in the oldest part much blackish brown frass; larva oval, legless: Rhamphus oxyanthae
4b mine circular with redddish brown frass in concentric arcs; larva an obvious caterpillar: Leucoptera malifoliella
5a corridor very irregular, without frass: Recurvaria nanella
5b corridor regular, with obvious amounts of frass => 6
6a corridor < 1 cm, usually in a vein axil, with much frass that almost fills the entire first part of the corridor: Bucculatrix bechsteinella
6b corridor longer, with proportionally less frass => 7
7a no egg shell visible where the corridor starts; corridor long and slender, not widenend in the end, may cross the midrib: Lyonetia clerkella
7b at the start of the corridor a shining egg shell; corridor usually shorter, often more or less widened in the end, almost never crossing the midrib => 8
8a corridor ends in an almost circular blotch: Stigmella sorbi
8b corridor either only weakly widened in the end, or forming a secondary blotch there => 9
9a most of the frass coiled: Stigmella oxyacanthella
9b all frass linear or dispersed => 10
10a corridor almost not widened in the end: Stigmella magdalenae
10b corridor clearly widened in the end => 11
11a frass occupies about 1/3 of the width of the corridor: Stigmella mespilicola
11b frass occupies at least 1/2 of the corridor widt: Stigmella hybnerella
12a mine small, no folds in lower epidermis; the larva soon leaves the mine and continues feeding in a folded leaf margin: Parornix anguliferella
12b mine larger, with one strong or several weak folds; pupation within the mine => 13
13a mine upper-surface: Phyllonorycter corylifoliella
13b mine lower-surface => 14
14a lower epidermis with one strong fold => 15
14b lower epidermis with everal weak folds => 16
15a pupa: the bases of the inner pair of cremaster spines just fall within the bases of the spines of the outer pair: Phyllonorycter cydoniella
15b the bases of the inner pair partly overlap with the bases of the outer pair: Phyllonorycter blancardella
16a mine 14-16 mm long: Phyllonorycter deschkai
16b mine 20-32 mm long: Phyllonorycter mespilella
Not included in the key: Callisto pfaffenzelleri; Caloptilia spec.; Coleophora trigeminella; Parornix anglicella, Parornix ornatella; Stigmella torminalis.
