No. They are adapted to winter temperatures. You can place them in a sheltered area outdoors. Do not bring them inside (or one fine morning you will find your house infested by hundreds of baby mantids)
Praying mantids are insects and lay egg sacs. There is no live birth involved.
They have some type of special coating on them that is tough enough for them to withstand extreme winters.
they are big enought to eat many spiders and makes a perfect match for spidera with it`speed but cannot eat big spiders like taurantulas or bird eating spiders
They need a lot of blood.
I'm not 100% sure, but I am quite positive that they do not. The egg-sacs are hardened a few hours after being created, and they don't move. Praying mantises only eat moving insects. It would be same to assume they would see the sac as simply a rock.
adult got more air sacs than children because there lungs are bigger than children so the air sacs have to fit in the adult's lungs
Yes, the female can lay infertile egg-sacs. Generally, if one has owned a mantis for a very long time, say 2 months or so, with no contact to male specimens or the outdoors, then she is most likely infertile. Usually they lay eggs about 1-3 weeks after being fertilized.

Air sacs need a rich supply of blood vessels to facilitate diffusion. A large number increases the surface area available to pick up oxygen and get rid of CO2.
The bronchi continue to divide into smaller and smaller branches until they end in air sacs. The air sacs in the lungs are called alveoli.
'trois sacs' means 'three bags' in French.
