Pericardial cells are present in a wide variety of insects and are thought to constitute the majority of 'athrocytes (nephrocytes)'. In contrast, peritracheal athrocytes have only been observed in Bombyx mori L. Although peritracheal athrocytes have a distinct morphology, it is unknown whether these cells are common to all lepidopterans. We anatomically compared eight lepidopteran species: Bombyx mori L. and Bombyx mandarina M. (Bombycidae); Samia cynthia ricini D. (Saturniidae); Agrius convolvuli L. (Sphingidae); Spodoptera litura F. and Mythimna separata W. (Noctuidae); Pieris rapae L. (Pieridae); and Glyphodes pyloalis W. (Crambidae). Of these species, only Bombyx mori L. and Bombyx mandarina M. possess peritracheal athrocytes.
围心细胞存在于多种昆虫中，并且被认为构成了大部分的“贮细胞（肾细胞）”。相比之下，气管周贮细胞仅在家蚕中被观察到。尽管气管周贮细胞具有独特的形态，但这些细胞是否在所有鳞翅目昆虫中都存在尚不清楚。我们对八个鳞翅目物种进行了解剖学比较：家蚕和野桑蚕（蚕蛾科）；蓖麻蚕（大蚕蛾科）；甘薯天蛾（天蛾科）；斜纹夜蛾和粘虫（夜蛾科）；菜粉蝶（粉蝶科）；以及棉大卷叶螟（螟蛾科）。在这些物种中，只有家蚕和野桑蚕拥有气管周贮细胞。
