When Chameleonnews comes back up there is an article there about Mantids. Also Wild Eyes Reptiles, the guys that have the WER gutload (I think there is a link to their site on the main page) has a very extensive page on care for mantids.
I got 2 pray mantis pods at green thumb for like $5. They are so cool, I have a pest free garden with out chemicals now. Its also fun to feed them tiny crickets once and a while.
Ive had a couple, I just keep them in huge plastic boxes with twigs and leaves, they get some of the same bugs my chameleon gets(crickets, wax and butterworms)
