I have one of those reptile screen cages that I used outdoors in the summer of 2012 and 2013. I put some mantids outdoors to give them some natural sunlight but I brought them in at night because I was worried about critters trying to break into the screen. (Have had an issue with chipmunks.) Anyway, it did work great but I thought the older mantids (especially Idolos) had more issues with their tarsus getting stuck in the net than the ones kept in terrariums with special netting added to the top.
Good luck with yours Danny. Your ooth looks great.
