1a larvae mine all their life => 2

1b older larvae live free => 5

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

2a pupation within the mine => 3

2b pupation outside the mine => 4

3b larva with thoracic feet and chitinised head; mine finally a secondary blotch: Metriochroa latifoliella

4a large blotch with copious frass: Silliana lhommei

4b narrow corridor almost without frass: Rosetea rosetella
