青杨楔天牛天牛科沟胫天牛亚科楔天牛属的 1种。又名青杨天牛。分布于中国东北、华北和部分西北地区，南至江苏。朝鲜和欧洲也有分布。是中国华北地区杨树的重要害虫，尤其在苗圃中发生严重。成虫较小,体长9～13毫米，体宽2.5～3.5毫米。黑色，全被淡黄色绒毛和杂有黑灰色长竖毛，头部黄色绒毛较密，前胸背板中区两侧各有一条淡黄色或金黄色绒毛纵条纹，每个鞘翅有4或5个黄色绒毛圆斑，雄虫鞘翅斑纹不甚明显，体腹面被黄、灰色绒毛。雄虫的额稍宽于长，复眼下叶长于颊，雌虫的额横阔，复眼下叶同颊近于等长。前胸背板的长宽几相等，密布粗刻点。鞘翅两侧近于平行，后端收狭，端缘圆形，翅面刻点较前胸刻点粗深，端部刻点减弱，有时翅面微显皱纹。一般1年1代，少数地区2年1代，以老熟幼虫在枝干的虫瘿中越冬。次年3月下旬开始化蛹，4月中旬开始羽化，成虫在嫩叶上进行补充营养，卵多产于2、3年生枝条上。幼虫孵化后侵入嫩枝为害，受害处由于输导组织被破坏，刺激形成纺锤形的虫瘿。6～7月幼虫增长很快，危害也最大。被害植物有山杨、毛白杨、小叶杨、加杨、箭杆杨、银白杨、黄华柳、白柳、青刚柳等。
