As some of you know, I'm taking a break from keeping mantids but in closing shop I've seen a couple of member concerns about feeding in a large tank or enclosure. I have kept p. chlorophaea 'in community' in a 15 gallon high tank for the past year. I don't use substrate (only adults) just lots of fabric plants and flowers. I have never had any trouble or cannibalism and I've only broken it down to clean twice. I use blue bottle flies and lots of them. I get the larvae from Ja-Da-Bait, take a portion out weekly and dump the pupae right into the enclosure. I smear some honey one the screened lid for the flies and mist every day. It's really easy and fun to watch. The mantids do spend much of their time hanging from the lid but they will travel all over the tank and often walk over each other. They mate and cast ooths and go home to Jesus when their number's up. The blue bottles are so sluggish that they can easily be caught and returned if they escape for any reason. The floor is littered with wings and someone's always eating. If I were to continue with any facet of mantid keeping it would be this colony method. I originally got the idea from Yen. He told me just to be sure there were plently of flies and there'd be no problems, and he was right. Just make sure they're blue bottles, if the species is up to it. They're fat and slow and the mantids easily catch them.
I just thought I'd share my experience for those who have concerns about mantids getting food in large spaces.
