Raising praying mantises

I’ve been curious about raising praying mantises for a while; according to Wikipedia, there are 2,000 species of mantids; only 20 of them are native to the United States. I’ve heard of people using them for a natural pest control, but apparently they’ll eat beneficial insects as well as pests, and will even eat hummingbirds! If you’re interested in raising them at home, here’s a good article to start with. Don’t release them unless it’s the right time of year, and they can survive in your area! (I’ve never seen one in the wild in the Northwest – I think that means if I hatch some, they’re my responsibility as long as they live.)
