Mantis versus Moth

I was walking in the backyard and noticed a fluttering sound coming from the flower garden in the back corner. Upon inspection, I found an amazing sight right out of wild kingdom. A 4-inch-long preying mantis had captured a very large moth in its front legs. It was proceeding to basically eat the moth's face. Despite the moth's intense struggle, it could not free itself. The mantis was basically strong enough to hold down the moth's attempt to fly away. Below are some pictures and a link to a video I shot.
