Mespilus germanica
The larvae feed on "Crataegus laevigata", "Crataegus monogyna", "Malus domestica", "Malus sylvestris", "Mespilus germanica", "Pyrus communis", "Prunus avium", "Prunus cerasifera", "Prunus insititia", "Prunus mahaleb" and "Staphylea pinnata". They mine the leaves of their host plant. The mine consists of a full depth corridor that gradually widens into an irregular elliptic blotch. The corridor generally follows the leaf margin over a long distance. The frass is blackish brown in the corridor and black in the blotch. Pupation takes place outside of the mine.
