Mespilus germanica
Adults are on wing from mid-May to mid-August. The larvae feed on "Amelanchier", "Chaenomeles", "Cotoneaster", "Crataegus douglasii", "Crataegus laevigata", "Crataegus monogyna", "Cydonia oblonga", "Malus domestica", "Mespilus germanica", "Prunus insititia", "Prunus spinosa", "Pyracantha coccinea", "Pyrus communis", "Sorbus aria", "Sorbus aucuparia" and "Sorbus torminalis". They mine the leaves of their host plant. The mine has the form of a small, hook-like corridor, mostly in a vein axle. The frass is deposited in a thick central line. The larvae soon leave their mine and resumes feeding living freely on the leaf. Larvae can be found from June to August. They are greenish yellow with a darker head. Pupation takes place in a white, ribbed cocoon on detritus.
