mine

Upper-surface corridor, in the end strongly widened and blotchy; may occupy a large portion of smaller leaves. Mines may coalesce, and contain several larvae then. Primary and secondary feeding lines very conspicuous (picture). Pupation outside the mine.

Homogyne alpina, discolor; Petasites albus, hybridus, paradoxus, pyrenaicus, spurius; Tussilago farfara.

notes

Atypical mines of this species have been observed on coltsfoot that remained corridors, perhaps in connection with being parasitised.
