large (3-5 mm), shining dark brown aphids suck at the stem and (underside of) ar least two year old branches. This damages the cambium, resulting in irregular growth in thickness, causing the bark to rupture lengthwise. Bleeding wounds and fungus infection are the result. Real gall formation is not involved. The large colonies are intensely visited by ants.
