Elsbeere
The larvae feed on "Amelanchier ovalis", "Amelanchier spicata", "Cotoneaster integerrimus", "Malus sylvestris", "Sorbus aucuparia" and "Sorbus torminalis". They mine the leaves of their host plant. The mine consists of a narrow corridor. It sometimes follows the leaf margin for a while, more often it is found along a major vein. The frass is concentrated in a narrow, regularly interrupted central line.
