I am also studying ants. I chose them because I have seen them all over the world, from Peru to New Zealand to China and the of course the US. I am making most of my observations in my backyard on cement but I also looked at some in Oregon and Washington. The most surprising thing I have witnessed if that ants run into each other all the time and do not seem to react to that. Something about myself if that I love working with pre-schoolers.
