Scotorythra paludicola, the koa looper moth, is a moth of the family Geometridae. It was first described by Arthur Gardiner Butler in 1879. It is endemic to the Hawaiian islands of Kauai, Oahu, Maui and Hawaii.

During a recent outbreak of S. paludicola in 2013 on Hawaiʻi Island, larvae were found to feed on isolated populations of the invasive tree Falcataria moluccana [1] near Akaka Falls State Park. Laboratory feeding trials of these larvae showed that they could complete their development at the same rate on both the normal host ( Acacia koa ) and the invasive tree ( Falcataria moluccana ). Three other exotic tree species, Acacia confusa , Prosopis pallida , and Leucaena leucocephala were not suitable host plants and all the larvae tested on these species died after 5 days of feeding.
