Red Velvet Ant (Wasp)

I saw a Red Velvet Ant outside today while I was mowing. First time I think I've ever seen one in nature. Here are some good picture's I found on the web.

Turns out it's actually a female wingless wasp - and known to have a powerful sting giving it it's alternate name of "Cow Killer."
