Thanks for the info!
The horned worms seem to really enjoy the sweet potatoes, broccoli, & spinach, as they have pretty much consumed 2 entire sweet potatoes and ate the rest of the greens. Now I think the worms have gotten pretty big, and subsequently seem to scare the chameleon. I guess now I'm gonna try to let them run their life cycle, and hope they breed and produce babies.
PS: That link is perfect!!
