An invasive species is any kind of organism that is not native to an ecosystem and causes harm to the environment, economy and possibly even human health. Gypsy moths, Asian longhorned beetles, emerald ash borers, and woolly adelgids are among the growing list of invasive insects that threaten U.S. forests and urban landscapes.
