What are superworms?

Superworms (Zophobas morio) are a type of darkling beetle larvae. They are a common feeder insect for both insectivorous and omnivorous reptiles, amphibians, invertebrates, and other exotic pets. This is because they are readily available, inexpensive, and easy to house. Superworms are high in fat and phosphorus, so they are best fed as treats or in a rotation with low-fat, high-calcium feeders.
