1a short, clear, full depth corridor mines, usually several together in the axils of the lateral veins; larvae with distinct heads and feet; older larvae only with their front parts in the mine: Epermenia chaerophyllella

1b larger blotch or corridor mine, not in groups in the vein axils; larva a maggot => 2

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

2a large blotch with conspicuous primary and secondary feeding lines; larva: rear spiracula each with 3 papillae => 3

2b corridor or blotch mine without conspicuous feeding lines; rear spiracula with more papillae => 4

3a larva in June – October: Euleia heraclei

3b larva in October – November: Cryptaciura rotundiventris

4a mine with a very inconspicuous lower-surface initial corridor; later mine a sometimes quite broad corridor or secondary blotch => 5

4b no lower-surface initial corridor => 6

5a later mine definitely corridor-like over its whole length; larva: upper backward-directed arm of cephalic skeleton black: Phytomyza archangelicae

5b backward-directed arm of cephalic skeleton brown: Phytomyza angelicastri

6a primary blotch without a hint of an initial corridor; usually several larvae in a mine: Phytomyza angelicae **

6b corridor mine: Phytomyza pastinacae

** there is a possibility that also Phytomyza sitchensis could be found on this host plant.
