I've never even heard of them before...
NVM- those are super worms...if the chameleon is small I wouldn't feed it an adult super worm until it's big enough to eat the worm. We feed our panther super worms and he really prefers them over roaches and even sometimes crickets.
And to breed them, each super worm needs it's own area away from other worms so it can pupate and then turn into a beetle. Once the pupae turn into beetles you can put them all together in a sterlite tub with some oatmeal as substrate and lots of fresh fruit and veggies ( We use whatever is left over from cutting up veggies for our meals).
