another mine from the same sample
mine
Oviposition generally at the upper side of the leaf, and not far from the leaf margin. The mine is a rather wide corridor, that often crosses a vein, and almost invariably runs from somewhere near the leaf margin in the direction of the midrib. Its first part is quite narrow, with a narrow central frass line. The next section is wider, and here the frass is distinctly coiled. In the final section the frass lies somewhat more irregular, and in a rather narrow central zone.
