Summarize this article:

This is a good starting number for beginning your own superworm colony. You can purchase live superworm larvae online or from a pet supply store in your area. If you purchase superworms online, check to make sure that the worms you are buying are shipped live. You can use plastic film canisters, partitioned craft boxes, condiment cups, or empty plastic cosmetic jars for this purpose. Poke or drill a small hole in the lid of each container so that your superworms can breathe. It's important to store your pupating superworms in their own containers so that adults and other larvae won't nibble on them while they mature. Isolating the superworms in dark containers will also stimulate the pupation process, which could otherwise take up to 5 months to occur naturally. Wheat bran or oatmeal will work well for this purpose. Use just enough to cover the bottom of the container. The substrate will serve as both bedding and a source of nourishment for the superworm larvae. There's no need to put any additional food in the containers for the superworm larvae. Some breeders recommend against using substrate altogether, since any source of food can slow down the pupating process. If you choose to leave out the substrate, make sure the larvae are already full size (about 2 inches (51mm) long) before isolating them. Once the superworms and substrate are in their containers, put the containers in a dark area, such as a drawer or cabinet. Make sure that the storage area is warm, preferably around 80F (27C). It is especially important to keep your superworms in a dark place if you are using transparent or translucent containers, such as glass jars or clear plastic condiment cups. Peek in on your superworm larvae occasionally over the next week to 10 days. After a few days, you should notice that most of your superworms have curled up into a "c" or "e" shape. By the end of a week or so, they should begin to transform into "alien"-looking pupae, with a shorter, cream-colored body and ridges that will eventually become legs. Any larvae that are stiff and straight or have turned dark in color are probably dead. Discard any dead larvae and replace them with live ones. Check the pupae occasionally to look for signs that they are maturing, such as darkening of the legs. It will take about 2 more weeks for the pupae to transform into beetles. Continue to store the pupae in separate containers until they mature. If you put the pupae together, the beetles that mature first might snack on the other pupae.
Purchase about 50 to 100 superworms. Place each larva in an individual, ventilated container. Put a little substrate in each container. Keep the containers in a warm, dark place for about 10 days. Check the larvae to see if they have transformed into pupae. Wait about 2 weeks for the pupae to mature.
