Carolina anoles, they're everywhere around here.
Like bats they're voracious insect eaters, they'll help keep mosquito, gnat and fly populations down. Unlikely to dump in the rainbucket.
Lots of birds and snakes, bigger lizards, etc., prey on them.
Carolina anoles change colors, they're usually a bright green. They vocalize a lot at night (making a soft 'eeep...eeep' sound).
The wetter the general area climate is, the more of them around. They now range, in TX, from the Hill Country, where they're cold-limited so far, east to LA, to the Valley (where they're very numerous) and Mexico.
