Does anyone have a list of all possible feeder insects for chameleon?
If anyone had that list, I'm afraid it would probably be a little large to post on these forums...
"Insects (Class Insecta) are a major group of arthropods and the most diverse group of animals on the Earth, with over a million described species"(Wikipedia)
So even if only 5% of all insects were edible to chameleons, you'd still be looking at a list of about 50000 insects...
However, I think what you are trying to ask for is a list of insects that are relatively easy to obtain, and practical to keep and breed.
You should start with a great book that is sold in the book store on this site:

What about any other roaches. Any other good ones that are simple?
Dubias (
Blaptica dubia - Orange spotted roach) are the best roach feeders. They're slow-moving, can't climb plastic/glass, don't fly. Their life-cycle is a bit longer than some roaches, and so they propogate a bit slower, but they seem relatively hardy (as most roaches are, I guess). They also have a reasonably good meat-to-shell ratio. And they seem to be readily available in the States.
Any other unique feeders?
Katydids. I can't tell you how to breed or keep them, and I don't even know how I would gutload them properly (just fresh grasses, I guess - similar to grasshoppers). But they are bright, and green, and jump around a lot: chams go crazy over them. They are also not bred/sold anywhere that I know of; you'll have to catch them in the wild.
But there you have it... a unique feeder.
They are super fast.. you can't catch them.. they can climb glass, plastic, anything.. you name it.. they can climb it and fast. They will burrow into your live plant pots and breed in the dirt in your chameleon's cages and the nymphs are often small enough to fit through screened cages gaps.
