Medium Silkworms for Sale
Medium silkworms run about 1/2″ to 1″, the popular staple size. They are the larvae of the silk moth Bombyx mori, and they suit mid-sized reptiles like bearded dragons and chameleons. Silkworms are soft-bodied and easy to digest, high in protein, and low in fat, so they make a strong staple or a nutritious treat. TC grows them in a Houston silkworm lab with clean breeding.
The Popular Staple Size
Medium is the size most keepers reach for, since it fits a wide range of mid-sized animals. So it works well as your everyday silkworm, and you can drop to the small size for younger animals or move up to the large size for bigger ones. Because silkworms are counted by hand, sizes are approximate.
A Soft, Nutritious Feeder
Silkworms have no hard shell, so they digest easily and carry a low impaction risk. That suits picky eaters and pets recovering or needing to rehydrate. Many reptiles take them even when refusing other feeders, so they earn a regular place in the diet.
Calcium and Variety
Silkworms have a better calcium balance than crickets or mealworms, one of the few feeders that come close to a healthy ratio. So many keepers feed them without dusting. Even so, vary the diet and lightly supplement for fast-growing or breeding animals, and feed silkworms as part of a rotation since they are high in moisture.
Care
Keep silkworms at room temperature, not in the refrigerator, since cold harms them. Keep them with their chow, since they ship with only 2 to 3 days of food. Buy more chow to grow them out or hold them, and larger worms eat faster. Cared for well, a batch lasts about a month.

Got these for my adult African Fat Tail male. He took to them right away! They came very well packed and alive despite FedEx having the box upside down for an extended amount of time. Highly recommend and definitely will back back to buy more!
