Commonly referred to as superworms, giant mealworms, zophobas, or darkling beetles. Zophobas morio is eaten as the larval stage and is 1.5 to 2 times larger than regular mealworms, at up to 2.25 inches long. The larvae are tan with dark stripes at the end and a dark spot on their head.

The adults are black and have a fused wing plate. Their abdomen is pointer compared to Tenebrio molitor and the thorax and abdomen are not as


Superworms naturally occure in the tropical regions of Central and South America, but have spread across the world for use as food for reptiles and other insectivorous pets. They are often found amongst rotting logs and leaves.[1]

Zophobas morio is a prolific breeder, which makes it a top choice for reptile food. One important difference between superworms and other darkling beetle species is that the larvae will not pupate if they are in close proximity to one another, so it is important to separate any worms which will become breeding adults. Once each worm has been separated, the container(s) (such as film canisters or a box similar to a sectioned bead box) should be placed in a warm, dark area. Otherwise, their care is similar to that of Tenebrio molitor. They should be kept in shallow bins with a substrate of grains such as oats or bran. Additional pieces of carrot, potato, apple, cucumber or other fruit or vegetable should be provided as a source of moisture.

This video demonstrates the breeding process.
