Spodoptera is a genus of moths of the family Noctuidae erected by Achille Guenée in 1852. Many are known as pest insects. The larvae are sometimes called armyworms. The roughly thirty species are distributed across six continents.

 No tufts behind collar as in Euplexia, but only tufts present on metathorax. Scales much smoother. Abdominal tufts slight. Fore tibial tufts are very developed. Cilia slightly crenulated. Antennae almost simple.
