隐翅虫素（Pederin）是一种由隐翅虫属Paederus制造出来的毒素。有研究指隐翅虫素是依赖在隐翅虫中的血淋巴中共生菌（Pseudomonas ssp.）所合成。对人体来说，隐翅虫素是一种非常强烈的毒素，只需要极低的浓度（每毫升一纳克）便能阻止正常细胞的有丝分裂。工作原理为通过抑制蛋白质和脱氧核糖核酸的合成。也因为有抑制细胞分裂的特性，隐翅虫素也被考虑为一种潜在的抗癌药。

Pederin is a vesicant toxic amide with two tetrahydropyran rings, found in the haemolymph of the Paederus genus of beetles, including the Nairobi fly, belonging to the Staphylinidae family. It was first characterized by processing 25 million field-collected P. fuscipes. It makes up approximately 0.025% of an insects weight (for P. fuscipes).
