Sanguisorba minor
The larvae feed on "Bencomia caudata" and "Sanguisorba minor magnolii". They mine the leaves of their host plant. The mine has the form of a short corridor, widening into a large full-depth blotch. All frass is ejected from the mine. The larva often moves to a new leaflet. Pupation takes place within the mine. The larvae are uniformly pale yellow with a dark brown head.
