Okay, so maybe this idea isn't one to pursue. I keep birds, and if they're that much of a pain, I'll probably go stir crazy trying to keep them out of the bulk bird food I buy.
I can't think of anything else though besides the mealmoths, greater and lesser waxworms. I really like using greater waxworms. I don't think there's much of a point culturing lessers since I have greaters, but I thought using a different type of moth larvae would provide more variety in the diet.
