Luzula sylvatica, Bunderbos (leaf tip to the left)

mine

Rather narrow corridor, upper-surface or interparenchymatous, 12-20 cm in length, about 2 mm wide. Mines yellow, contrasting against the dark green leaves, but sometimes they are deep purple (Blad, 1993a). The corridor changes direction at least twice. Generally it does not leave the blade. Frass in one or two large lumps. Pupation inside the mine.
