Medium Superworms for Sale Medium superworms run about 1″ to 1.5″, the versatile everyday size. They are the larvae of the darkling beetle Zophobas morio, a different species from mealworms. They are high in protein, and their active movement tempts reluctant feeders. TC raises them on grasses, oats, bran, and wheat for a well-rounded gut-load. They suit a wide range of insectivores. The Versatile Everyday Size Medium is the size most keepers reach for, since it fits many animals. Bearded dragons, leopard geckos, smaller monitors, larger frogs, birds, and fish all take them. So it works well as a main feeder, and you can step up to the large size for bigger pets. Higher Fat, So Feed in Moderation Superworms are richer and higher in fat than mealworms. That suits active or underweight animals, and it makes them a good treat. For pets prone to weight gain, feed them in moderation and as part of a varied diet rather than the only feeder. Dust for Calcium Like most feeders, superworms are low in calcium, so dust them with TC Calcium Ultra Fine before feeding. They are not the same as calcium-rich black soldier fly larvae, so pair them with variety and supplementation. Care: Keep Them Warm Store superworms at room temperature, between 75 and 85°F, and do not refrigerate them. Cold harms superworms, which is the opposite of mealworms. Keep them in a bran substrate with a slice of vegetable for moisture. Kept together, superworms stay as larvae and only pupate when separated one by one. Best For Bearded dragons, leopard geckos, and smaller monitors. Larger frogs, birds, and fish. Active or underweight animals that need richer food. A versatile everyday feeder for mid-sized pets. Not Best For The largest animals, which suit the large size. The only staple for weight-prone pets, given the fat content. Cold storage, since superworms cannot be refrigerated. Recommended Add-Ons Premium Worm Bran as food and substrate to keep them. Large Superworms for bigger animals. TC Calcium Ultra Fine to dust them before feeding. Black Soldier Fly Larvae as a calcium-rich feeder for balance. Live Superworms to browse sizes and food. Frequently Asked Questions What are medium superworms?
