This creamy yellow sub-adult female obliged to pose for me. I'm pretty sure she was a Stagmomantis limbata, of which I saw several there.
This adult female was hanging out on the patio area of the snack bar at Zion Lodge. She is also the mantis from my previous post. The full-size wings rule out S. limbata. She did have dark spots on the insides of her front legs, so she could be Mantis religiosa.
