Hmmm. let me think for a minute. Red Fire Ants are animals and were imported from South America to Mobile Alabama around 1930 so they are non-native. I have about a trillion of them in my yard at any given time and the little nasties are coming above ground as the weather warms, so would that count?
Just kidding....the only fire ant I will purposefully handle is one I have smashed into an unrecognizable clump of organic matter......
On the other hand I am pretty sure one of my neighbors came from another galaxy.......
