It seems defining what &quot;native&quot; means on Hawaii is a bit sketchy. Clearly <i>no</i> animals were on the islands when they first were created, so everything is more or less &quot;invasive&quot;.<p>Speaking of ants that live in trees, the Big Island is being overrun by the Little Fire Ant, which has already spread across much of the rainy side. I&#x27;m sure it protects the trees from pests, too, but in this case that unfortunately also includes humans. They have a nasty bite, and are very hard to control, which is making farming in infested areas hell. <a href="http:&#x2F;&#x2F;littlefireants.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;littlefireants.com&#x2F;</a>
