2a case yellowish brown to light grey, slender: Coleophora peribenanderi
2b case blackish brown, thick-set: Coleophora paripennella
3a older larvae live free among spun leaves => 4
3b larvae mine all their life => 8
4a mine small, of indefinite shape: Cnephasia stephensiana
4b mine not unusually small, a clear corridor or blotch => 5
5a blotch mine => 6
5b corridor => 7
6a the upper side of the mined leaf curls inwards, exposing the underside: Agonopterix nanatella
6b the mined leaf remains flat: Tebenna micalis
7a larva: head and prothoracic plate black: Agonopterix propinquella

8a larva a maggot => 9
8b larva with chitinised head => 11
9a corridor from start to end: Chromatomyia cf. syngenesiae
9b the full grown mine is a blotch => 10
10a a bloth from the beginning; the mine begins at an under-surface egg shell: Pegomya steini (occurence on this host very questionable)

11a larva with thoracic legs => 12
11b larva without legs: Orthochaetes insignis
12a mine begins as a corridor, ends as a blotch with strong length folds: Perittia carlinella
