Fragaria vesca
The larvae feed on "Fragaria moschata", "Fragaria vesca", "Fragaria viridis", "Potentilla erecta" and "Potentilla sterilis". They mine the leaves of their host plant. The mine consists of a narrow, strongly contorted gallery with grey brown frass. The gallery ends in an elongate blotch or broad corridor that frequently overlaps a part of the earlier mine. Pupation takes place outside of the mine.
