A Carolina Anole (Green Anole). They are native to the Southeastern US, but have been introduced to other places (with not great results).
You can find them climbing around a swamp, or running across a porch floor (or anywhere else for that matter).
We also have a Brown Anole which can drive out the more docile Carolina ones. And of course the Brown are invasive from the Carribbean. Basically pets turned loose and now an issue.
I have learned to live in harmony with the little guys. It was either that or move back north. Anole are fast, and numerous. If they stay out of the house we do just fine.
