Q.Caring for babies praying mantis
Hello.. i brought a praying mantis in my house because it was always near the front door for like a good 2 mths.. everyday. And I let the door open watching her (by then I already named it Steve lol) so she came in and stayed by me everyday. Kinda weird but I love it.. but now she gave birth this past Sunday and laid an egg.. I had NO idea what the heck was coming out of her but I looked it up and ta-dahh Steve became Stephanie. But now I’m so stuck on how to keep these babies alive.. I live in Ct.. is so cold.. what should I do? I really wanna save the ones that don’t eat eachother. And She’s in 9×9 aquarium and she layed her egg right at the top.. please help me.. I’m watching all these videos but I wanna ACTUALLY talk to someone. And I think u can help.. i really like this little fella and want her babes to be healthy.. Thank u

You, actually, don't have to do much of anything! Just care for the mantis as you would normally. Within 4-6 weeks you will see it hatch with a few hundred miniature mantis. There won't be many left when they reach maturity, but when you find that a few have survived and are growing, then you can release them in your garden. You don't really want to overcrowd the mantis.
