Phyllocrania paradoxa questions

[ReignofInvertebrates]

I’m a bit new to keeping mantids. I’ve had some ghosts for a few months and they’re now 5 or 6i I believe. I’ve read that these are communal but I figured I’d check in with the experts here before I move them into a communal tank. Also, just out of curiosity is there an easy way to tell if they’re mature? Thanks in advance.

Don’t keep them communally, they won’t hesitate to eat one another. They are mature once they have wings. If you can give me a picture of each u can identify if they are actually i5/6.
