Spodoptera mauritia, the lawn armyworm or paddy swarming caterpillar, is a moth of the family Noctuidae.

Forewings with sub-basal, antemedial and postmedial double waved lines indistinct.

[3][4] The larvae feed on various grasses, including rice,[5] wheat, Cynodon, Pennisetum clandestinum, Sorghum bicolor, Oryza sativa, and trees such as Casuarina equisetifolia.

[8] Plants attacked by caterpillars have skeletonized leaves, shot holes, and dieback stems.

Commonly the entire paddy crop dies within few days due to swarming attack.
