Host plant in Israel. Q. boissieri .

Life history. Known only from the bud galls of the sexual generation, which resemble a small carambola fruit, with 3–4 distinct longitudinal ridges, 5–7 mm long and 3–5 mm wide and single-chambered ( Fig. 26 ). Young galls are green and fleshy, turnning pale brown when mature.
