Without a full spectrum of their natural diet, these things have a turquoise color instead of a green one.
They still are able to go through their full life cycle just fine, they just aren't camouflaged for live foliage.
All I know about growing them is that we had a limited number of them on wet substrate in 32oz containers, and the breeding adults were fed hummingbird-style on a syrup that was boiled in-house.
You don't want these anywhere near your garden though.
