Even with the risk of boring you with repetitions, I'm keeping all my mantids in large enclosures, most of them planted. I don't use a single box anymore, except for singletons that require that I have an eye on them (specimens that I need for the collection etc.). That mantids cannot find food in large containers is simply a myth. Cleaning isn't an issue, as debris is eaten up by feeder insects (roaches, firebrats) and springtails. I clean the window and the cage walls about 1-2 times a year when the cage is empty for some days. That's also the time I cut the plants back to a good size.It's ok for you all to use cups and stuff like this, but telling that large enclosures don't work it's just not true. So, LectricBlueEyes, just go on with it and make your own experiences.
