Back when we got the Ants we also got a Praying Mantis Egg. I never knew that was how they came. So after having the egg sit in a cup for about a month the egg finally hatched. It had over a hundred little tiny Praying Mantis come out of it. We let most of them go around our yard. Then we released some around the neighborhood. I hope they survived because we have had some cold nights since then. We tired to keep some in but they only lasted a couple days & then they died.
This is the egg!

They look just like they do when they are adults, but just super, super tiny!

This is a butterfly pavilion. But we kept them in it instead!
