灰翅夜蛾属

灰翅夜蛾属（学名：Spodoptera），又称夜盗蛾属，是鳞翅目夜蛾科的一个属，由法国昆虫学家Achille Guenée于1852年发表描述。本属包含约三十种分布在六大洲的物种，主要危害蔬菜、禾本科作物及草地植物等，常给农业生产造成巨大的经济损失。如甜菜夜蛾beet armyworm, Spodoptera exigua Hübner属于此属。2002年，Pogue以形态特征为依据，进行了夜盗蛾属最早的亲缘关系研究，2011年，他又以细胞色素c氧化酶亚基1的DNA序列进行本属十种物种与若干外群的分子种系发生学分析。2015年，一篇分子种系发生学研究也以细胞色素c氧化酶亚基1序列分析了夜盗蛾属27种物种间的亲缘关系，

本属物种的后胸具有毛丛（tuft），领部（collar，即前胸背侧的突起）没有毛丛，腹部有些许毛丛，前肢胫节上的毛丛则相当茂密，触角外形简单。
