Initially a large upper-surface blotch, without a preceding corridor. Later also the sponge parenchyma may be consumed (possibly only in crowded situations). Mine yellowish-green, first part often browned. Frass in numerous grains scaterred through the mine. Up to seven larvae in a mine; they may leave an emptied leaf and restart elsewhere. Pupation in the soil. The imago’s chew elongated windows in the leaves.
