Great shots - that third one is the best in my opinion!
I think the 3rd one came out the best too, might have been the only picture I managed to get the camera to focus right on the mantis, it was a bit on the small side.
I have yet to spy a preying mantis this year. We have a colony of five-line skinks nearby, but no joy there either. Took a few shots of a Cicada Killer though.
Never seen a Cicada Killer before so I had to look it up, looks like a giant wasp.
