Easy. All gut-loading is is feeding the mealworms nutritious food, so that they will be more nutritious for your lizard. All you really need to do is put something in there for them to munch on for awhile before you give them to your lizard. A lot of people might put a little scrap fruit or vegetable bits in there. You probably have some kind of nutritional supplement powder for your lizard(and if not, then it's a good idea to), and putting some of that in there for them to eat is good also. There are also commercial "gut loading" products make specifically for the purpose of feeding to feeder insects.
Yeah, he's been doing that. Oh and thanks for the reply, too. The only thing that is weird is that they are mutating some, but he feeds them to our lizard anyways. Is it normal for them to mutate? And is it safe? Actually they are staying alive much longer this way than when we just bought them and stuck them in the fridge.
Granted, I know nothing of lizards or meal worms (although I do fish with meal worms). But I'm curious, how are the meal worms "mutating"? Or maybe you mean "molting"? Either way, please satisfy my curiosity. Thanks!
Hahaha. Yes, it's completely normal for them to "mutate." It's a natural part of their life cycle. See, mealworms aren't actually "worms" at all, they are the larval form of the darkling beetle. This "mutation" you are seeing is actually their pupal form. If you leave them alone long enough while they are pupae, eventually they will metamorphosize into small black beetles. It's basically the same as the whole caterpillar/cocoon/butterfly thing. It's completely safe to feed them to your gecko in any of these life stages, but i find that my own Leopard Geckos don't care for the beetles(my tarantulas will eat them, though). They don't seem to even notice the difference between the mealworms and mealworm pupa, though. If you keep some of the beetles together, you may even be able to breed them.
