Humulus lupulus, Germany: Xanthen

mine

Long, narrow, little widening corridor, often following a vein for a considerable distance. The thin leaves easily tear in here, also because the mine is relatively deep. Frass in two neat rows of grains along the sides. Pupation outside the mine; contrary to A. flaviceps on the same hostplant, the exit slit is in the upper epidermis.
