1a fleck mine; larva mines from a case => 2

1b no fleck mine, larva not in a case => 8

1c galls, etc => 100

3b species of Central Europe and the Mediterranean Regiond => 4

4a case < 10 mm, clearly consisting of 2-3 leaf fragments that usually differ in colour: Coleophora bilineella

4b case larger, its composition less clear; case generally unicolorous: Coleophora helianthemella

5a hole slit-like or oval; case elliptic, not covered by detritus or sand grains: Crinopteryx familiella

5b hole more roundish; case more or less helicoidal, covered with sand grains => 6

6a case higher than broad: Apterona nylanderi

6b case about as high as broad => 7

6c case definitely lower than wide: Apterona helicinella

7a convolutions very shallow: Apterona gracilis

7b convoltions very distinct: Apterona helicoidella

8a mine uppersurface; larva and pupa broad, with a strikingly large, toothed anal shield: Dicladispa testacea

8b mine full depth; larva slender, anal shielf, if present, small and not toothed => 9

9a short corridor, ending in an oval excision: youth mines of Coleophora species => 3

9b mine begins with a large corridor section; final section may end in a short secondary blotch => 10

9b mine with or without a short initial corridor, followed by a large primary blotch or tentiform mine => 12

10a corridor from start to end: Parafomoria cistivora & P. pseudocistivora

10b mine ends in a secondary blotch => 11

11a on Cistus ladanifer in Portugal or southern Spain: Paraformoria ladaniphila

11b on Cistus albidus, perhaps also incanus, along the Mediterranean coast from Gibraltar to Genua: Parafomoria liguricella

12a tentiform mine => 13

12b ± flat mine => 14

13a pupation within the mine: Perittia piperatella

13b pupation outside the mine: Triberta cistifoliella

14a pupation within the mine: Schistophila laurocistella

14b pupation outside the mine => 15

15a blotch, preceded by a short corridor: Mompha miscella

15b blotch not preceded by a corridor: Urodeta hibernella

100a Nematoda => 101

100b Acari => 102
