Sorbus torminalis
The larvae feed on "Amelachier parviflora", "Cotoneaster racemiflorus", "Cotoneaster salicifolia", "Sorbus aria" and "Sorbus torminalis". They mine the leaves of their host plant. The mine consists of a short, full depth, gradually widening corridor. The last section has the form of an elongated blotch. Pupation takes place outside of the mine.
