Here is a good site for rearing waxworms with links. They will pupate (not always spinning sometimes just forming their pupal skin (brown, hard, shows wing and body form) and emerging within about 10 days. I combine bran, rolled oats, honey and beeswax (you can get this at most any health food store or online) for their bedding/food.
A note about refrigeration From NY Worms (http://www.nyworms.com/waxworms.htm):
If you choose to refrigerate your Waxworms, do not take their container out of the refrigerator for any longer than the time necessary to pick the number that you wish to use. Condensation will form on the worms and in the cup, causing your worms to die.
