Gall. (Fig 182). Hard detachable, multilocular galls that burst out of the twigs and are usually clustered in rows. When young, galls are greenish, later they turn rusty brown on the top with light brown sides. A single gall up to 15 mm wide and 20 mm long; the gall cluster can exceed 60 mm in length. (Ashmead 1896, Russo 2006). Galls produce honeydew (Nicholls et al. 2017).

Biology. Only the asexual generation is known, inducing galls on Q. chrysolepis. Galls develop in autumn, mature in October-November; adults emerge in mid-winter.
