Koa moth (Scotorythra paludicola) abundance in response to koa moth outbreak, 2013-2014

The koa moth (Scotorythra paludicola) is a species of moth that has been reported to irrupt in great abundance on occasion over the past 100 years, sometimes defoliating its host plant, koa (Acacia koa), during the event. This data release includes metadata and tabular data that document temporal abundance patterns of the koa moth (adult stage; Scotorythra paludicola) during an outbreak that resulted in widespread defoliation of koa across much of Hakalau Forest National Wildlife Refuge during 2013-2014. The data set documents numbers of moths collected in malaise traps during the outbreak. Malaise traps were deployed at several sites during the outbreak to allow moth abundance to be tracked over time.
