Scotorythra paludicola Scotorythra paludicola 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. The larvae mainly feed on "Acacia koa", but have also been recorded from "Falcataria moluccana", "Grevillea" and "Tristania" species. On occasion, this species develops enormous populations and defoliates entire areas with koa trees. During a recent outbreak of "S. paludicola" in 2013 on Hawaii Island, larvae were found to feed on isolated populations of the invasive tree "Falcataria moluccana" near Akaka Falls
ʻApapane Lānai. Apapane generally feed on nectar from flowers, preferably from the "ōhia lehua" ("Metrosideros polymorpha") tree. These birds are mainly found in "koa" ("Acacia koa") and "ōhia lehua" forests where the flower count is high. Although primarily nectarivorous, the diet of a grown apapane also includes a variety of insects like grasshoppers, caterpillars and bugs of all sorts. The breeding season is from January through July. The nest of the apapane is usually placed in the crown of a "ōhia lehua" ("Metrosideros polymorpha"); nests have been found in tree cavities and lava tubes as well as in the top of
