I love all insects in the mantid family!
I try to get one every so often. They do only live for one season to one year but they are so cool. Once they learn you will not hurt them they will willingly walk onto your hand. It's fun to hand feed them large things like grasshoppers.
They are very neat little insects with a type if intelligence not seen in other insects. Leaf bugs and stick bugs are also very cool but the chinese praying mantis (the large green ones we have here) are the coolest when it comes to size and the way they act.
