Check out the links below. We beleive they're the best you'll find when it comes to ant keeping.
Another one of our projects, Taxonomers is a database of ants for ant keepers by ant keepers. Featuring ant locations and identifications by people who keep ants. The more you use it, the better it'll be. Stop on by and upload a few of your own locations or identifications.
AntWeb is a treasure trove of ant identification. Found a queen ant? Then hunt through this website to find what type of ant you've got. Beware though, most photos in the archive are of workers only. You'll have to hunt a little harder to find queen ant photos.
