2a corridor from start to end; puparium in the mine; frass in discrete grains: Chromatomyia horticola
2b eventually an upper-surface blotch; pupation usually after the mine has been vacated; frass partly in thread fragments => 3
3a larva: mandible with 2 alternating teeth (seen from aside seemingly 4!); mine communal, 5-10 mm wide at its very beginning: Agromyza ferruginosa
3b larve: mandible with 2 not alternating teeth; mine initially individual, starting with a 1-maggot corridor (that will be overrun later); usually several young mines coalesce, forming one large communal mine: Agromyza abiens
Not included in the key: Cnephasia incertana, stephensiana; Coleophora pulmonariella; Phytomyza pulmonariae, Phytosciara halterata, macrotricha.
