To keep praying mantids alive, we must use fewer pesticides and have lots of mature plants to provide shelter for them. You also shouldn't keep egg cases. Praying mantids usually live in places with warm or tropical climates, but European mantids are native to cool climates. Praying mantids are capable to eat tree frogs. The male praying mantis has wings but the females do not.
Mantids have triangular heads which can swivel easily.
Sometimes they can look like humans when they cock their head to the side or look over their shoulder. While the mantids are waiting to jump for prey, they hold their forelegs against their prothorax. They hide in a hiding spot, grabbing passing insects with their spiny forelegs. People can confuse the praying mantis and the walking stick as the same insect, but they are not the same. I have enjoyed this project very much.
