Red Velvet Ant
I was looking online for what this awesome looking insect was called. I love ants and it looks like one but behaved like a wasp. It would move quickly with the abdomen upright. I saw everyones pictures and sure now that this is what it is. It was difficult to photograph because of its irratic movements.
Your Velvet Ant is a Cow Killer, Dasymutilla occidentalis. Obviously, the quality of your photographs must rise with the level of difficulty, since the detail on your photograph is awesome.
