I beg to differ...
Superworms can turn into beetles, it's just tougher
they need to be put in a separate container which can be as small as a camera photo container with about an inch of substrate
they need warmer temps than mealies to pupate and they take longer
the pupae and the beetles look similar to those from mealworms except they are bigger.
rather than a damp papertowel, I put in vegetables like a carrot or a zucchini
fruits, like apples, tend to rot since the moisture content is higher
Good Luck !
