A half sized Mantis showed up on the deck the other day. They are truly and interesting insect. This reminded me that I haven't seen a Walking Stick in I don't know when. I use to find them all the time but that was in South Dakota. Didn't see Praying Mantis' until I came to Ohio. They always look like they are watching you. They cock their heads as if listening for something but I have no idea as to whether they have ears of not, my guess is not. I figure they get vibrations in the air to their antennae.
