I have one ghost mantis, Liliana. She's very calm and reserved, and prefers not to be handled.
My spiny flower mantis, Elspeth, is a good little killer who gladly comes out to visit, but will try to stab anything that moves.
Finally, my two Chinese garden mantises, Superstar and Major Tom, are both too young to have much personality. Superstar has figured out that she should walk down the wall when I open her enclosure, to be better positioned for moisture and fruit flies.
