Well, most of the freeze dried insects are nutritiously useless. I'm all for frozen foods. I order 100's of frozen rodents at a time. There is a term in the herp hobby world called gut loading, which means to feed the insects high quality food right before feeding them to your animal, because they don't retain nutrients long, even when they are alive. Some of the larger caterpillars can be sold dried and have a little nutrition left, silkworms in particular. Sold as Zoo Med's Can O' Pillars. But they still don't seem to have the same amount of nutrition.
If I actually listed what and where all of the bugs are in my house, you would think I was nuts. Some are in the fridge. Butterworms, wax worms, and mealworms can be held in a stasis this way almost indefinitely. I keep some mealies out to eat and gutload so they are nutritious before feeding. I have silkworms in feeding pods, if I buy them small I can keep them a few weeks before they cocoon up. Superworms & Phoenix worms in small containers, supers I can get a few weeks out of, the phoenix's go much quicker. Crickets are in a large tub, I buy med's (5/8"), and I can get a few weeks out if 'em by the time they are over 1".
