Over the winter I was w/ my uncle picking spikes for ice fishing. They are small grubs that burrow into the stem of goldenrods. I found two mantis egg sacks. I left them outside until about two weeks ago, I then put them in a 10 gal aquarium with cloth over the top so they couldn't escape. They hatched today and they are all over the tank. lol On my way to the pet store now so I can get them their first meal. I'm so excited as I've wanted to do this since I was a child. Happy to be part of the club and I will update w/ some pics soon.
