1b mine otherwise => 2
1c galls, etc => Tables for all parasites per species
2b gallery => 3

3b frass in strings; pupation outside the mine => 4
4a corridor pinnately branched; main branch overlying the midrib Liriomyza strigata
4b corridor not pinnate, freely winding through the leaf: Liriomyza bryoniae
5a at the start of the mine a lower-surface group of elliptic egg shels; larva a maggot: Pegomya hyoscyami
5b no egg shells; larvae with well-visible feet and head => 6
