I had a large mantis for a while. They generally only live for about a week and a half so don't get too attached. I would hit flies and knock them out a little so they could just walk near the mantis, then he/she would see them and grab them. But don't force feed them, they don't like that. A little soda bottle cap full of water will be fine for it, but you will never see it drink, it will though.
I have some video of mine eating the flies, I could probably get them for you.
Another thing: Mantis's don't like cages. They tend to know when they are trapped and won't eat or do anything while in captivity. I just let mine roam, and it stayed because I fed it. Shortly after he arrived he died though, just out of no where.. he looked like he was sick and fell over. I almost cried... almost.
