I think many people don't realize how many different kinds of mantids there are. Until I became interested in them myself, I only ever knew about the "brown ones and the green ones."
I think simply having praying mantids in the house (we only have Carolinas and Chinese right now) just blows some people away. I have most of my mantids in my office, but one was out in the den on the coffee table a few nights ago when a neighbor stopped by. She was just talking away about something and suddenly she said, "Oh my GOD!!! There's a PRAYING MANTIS on your COFFEE TABLE!" (Of course he was in his enclosure). I took her back to the office and showed her all my mantids, and she was just totally fascinated. Now, whenever she sees me outside, she says, "Are you looking for another mantis?" or "Hunting food for your mantids?" I honestly don't think she ever realized people kept mantids in the house. LOL
