parasite

During late summer the larva lives in a tunnel in the pith of a young thin shoot. The
± 3 cm long tunnel runs from the base of the shoot upwards. No frass is ejected, neither was frass found in the gallery. At the end of the gallery a narrow-oval exit opening is made. Just below the exit the gallery is closed by spinning. Pupation follows in late autumn, in the gallery.
