I used to raise and sell exotic mantid species.
That's how I raised the $$ for my chams
You would be surprised to know they actually make good starter pets
for kids.
Their behaviour is much more like an animal then an insect
They make amazing pets! They will actually look at you in the eye, and you don't get that from any other insect (atleast I don't know of any!).
Plenty of exotic mantids to choose from, too. Although I doubt any of the people here would use anything other than chinese/native mantids. The exotics can cost a pretty penny!
I don't have any problem with people using the common ones as feeders, although I would cringe at the idea of someone doing that here. Mantids are quite rare in my area! Plenty of anoles around here, and I've used countless as feeders. I'm sure some wouldn't agree with the idea, though.
And for the time I was breeding mantids, I actually made quite a bit of money.
