I'll just throw this in. The lady who sold me my Cham says no mealworms, no superworms, no large crickets. The basic idea is they have trouble digesting exoskeleton. I use softer bugs like waxworms, grubs, and small crickets. The problem with large crickets is as their core bodies are easily digested their Jumping legs are not. All this hard exoskeleton can lead to impaction. Chameleons are a very delicate species to maintain. I prefer to err on the side of caution.
