Sorbus torminalis
The larvae feed on "Cotoneaster nebrodensis", "Malus sylvestris", "Sorbus aria", "Sorbus aucuparia", "Sorbus chamaemespilus", "Sorbus intermedia" and "Sorbus torminalis". They mine the leaves of their host plant. The mine starts with a lower-surface epidermal corridor, but soon the larva starts feeding on the sponge parenchyma. The mine then becomes a flat lower-surface blotch. After leaving the mine, the larva lives freely under a folded leaf margin or in a fold at the underside of the leaf, in its centre, that is covered with silk.
