I went to the Wichita Mountains in Oklahoma to find these guys, and they did not disappoint! I found a bunch of them, from as small as 6 inches long to a couple that were 15 inches long!
I was quite surprised at the speed of these predators. This one saw a grasshopper in the distance, out the corner of his eye. In a flash he dashed over the 60 feet of rocky terrain and pounced upon the grasshopper before it had a chance to hop away!
