I found this ant crawling on my porch here in the Costa Mesa, California area. This is surprising because I don't think I have ever seen any ant other than an Argentine ant in any of these coastal Orange County cities before. This ant is kind of a dark red color, and about the size of an Argentine ant. I wasn't even sure it was an ant when I first saw it, because of the size of it's head, but after taking a closer look, it's definitely an ant, and one I have never seen anything like here in Southern California.
I later found a few more of these crawling around on my porch, so there's obviously a nest somewhere near by. I also noticed some of these are VERY tiny, about 1.5 mm in length.
Edit: This species name changed from Pheidole moerens to Pheidole navigans.
