1b no fleck mine => 3

1c galls, etc => Tables for all parasites per species

2a composite leaf case: Coleophora serratulella

2b spathulate leaf case: Coleophora odorariella

3a corridor => 4

3b blotch or tentiform mine => 5

4a corridor pinnately branched, overlying the midrib and side veins; pupation outside the mine: Liriomyza strigata

4b corridor not associated with the leaf venation; pupation within the mine in a, generally lower-surface, pupal chamber: Chromatomyia cf syngenesiae

5a lower-surface tentiform mine, often purple coloured: Aspilapteryx limosella

5b full depth blotch; upper surface may be wrinkled => 6

6a no central accumulation of frass; pupation external: Scrobipalpa brahmiella; see also Scrobipalpa pauperella

6b probably: a central accumulation of frass, where in the end pupation takes place in a globular cocoon: Pseudorchestes purkynei
