Sanguisorba minor
The larvae feed on "Agrimonia eupatoria", "Filipendula", "Fragaria moschata", "Fragaria vesca", "Fragaria viridis", "Potentilla tabernaemontani" and "Sanguisorba minor". They mine the leaves of their host plant. The mine consists of a gradually widening, relatively broad corridor, generally following a thick vein or the margin. The frass is irregularly scattered, occupying at least one third of the width of the corridor.
