I found a praying mantis in my back yard and have her in a 5 1/2 gallon aquarium. I put in a grass hopper about eight flys a couple spiders and a beetle. But she won't eat she is all green and i pretty sure she is a Chinese kind. I would like to mabe get a couple more as pets, learn how to make wing/wingless fruit fly cultures, raise crickets etc. Egg cases would be fine to.
