Dichotomous table for leafminers

1a fleck mine, either long and narrow along the leaf margin, or more or less circular and in the leaf centre => 2

1b gallery or blotch => 3

1c gallen etc => Tabellen voor alle parasieten per soort

2a linear fleck mine: Bucculatrix spec.*

2b normal fleck mine in the centre of the leaf: Coleophora obviella

3a larva with thoracic feet and chitinised head => 4

3b lara a maggot => 5

4a the larve mines life long: Scrobipalpula diffluella (?)

4b only the young larvae mine; later they live among spun leaves: Cnephasia sedana

5a pinnately branched gallery; main and side branches on top of the midrib and side veins: Liriomyza strigata

5b gallery not determined by the leaf venation => 6

6a pupation within the mine, in a, generally lower-surface, pupal chamber: Chromatomyia cf syngenesiae

6b pupation external: Phytomyza kyffhusana

* According to Hering (1957a) this should be Bucculatrix fatigatella, but the description he gives of the mines does not seem to fit fatigatella.
