Superworms are common in the reptile pet industry. In the search for easy-to-raise insects to use as food for captive reptiles and amphibians, superworms quickly moved into the spotlight, and have been a staple feeder insect ever since.

They should not be confused with giant mealworms.

These insect larvae resemble very large mealworms, about 1.7 to 2¼ inches long (50-60 mm) when full size. Once they reach adult size, the larvae pupate, and later emerge as large, black beetles. The larvae will not pupate if kept in a container with many other larvae, where they receive constant bodily contact.  Keeping superworms this way is commonly used to hinder pupation.

Superworms are accepted by lizards, turtles, frogs, salamanders, birds, koi and other insectivorous animals.
