Mealworms vs. Superworms — What's the Difference?
Edited by Tayyaba Rehman — By Fiza Rafique — Published on March 1, 2024
Mealworms are small, nutrient-rich insects ideal for feeding pets and used in composting, while superworms are larger, have a higher fat content, and require individual housing to pupate.

Key Differences
Mealworms, the larval form of the Tenebrio molitor beetle, are known for their high protein content and ease of breeding, making them a popular choice for pet feed, especially for reptiles, birds, and fish. Superworms, on the other hand, are larvae of the Zophobas morio beetle, and due to their larger size and higher fat content, are favored for feeding larger pet species that require more substantial meals.
Mealworms can be easily stored in a refrigerator to slow down their metabolism and prolong their larval stage, while superworms must not be refrigerated as they require a warmer environment to remain active and healthy. This difference in storage requirements is crucial for pet owners to ensure the longevity and quality of their feed.
Mealworms are often praised for their role in waste reduction and composting, as they can consume a variety of organic matter, turning it into nutrient-rich compost. Superworms, although also capable of composting, are less commonly used in this capacity due to their more specific care requirements and larger size, which makes them less efficient in smaller-scale composting systems.
The breeding process also differs significantly; mealworms can be bred in large groups with minimal space, making them a more accessible option for those looking to cultivate their own feedstock. Superworms require individual containers for pupation to prevent cannibalism, making their breeding process more labor-intensive and less space-efficient.
In terms of nutritional content, mealworms offer a balanced diet but with slightly less fat compared to superworms, making them a healthier choice for animals with lower fat dietary requirements. Superworms, with their higher fat and calorie content, are best suited for occasional treats or for species that benefit from a richer diet.

Common Curiosities
How do I breed mealworms or superworms?
Mealworms can be bred in groups with minimal space, while superworms require individual containers to prevent cannibalism during pupation.
Are mealworms or superworms better for feeding pets?
It depends on the pet's size and dietary needs; mealworms are generally better for regular feeding due to their lower fat content, while superworms are suited for larger pets or as occasional treats.
Can I refrigerate superworms like mealworms?
No, superworms should not be refrigerated as they require warmer temperatures to stay healthy.
What are mealworms used for?
Mealworms are primarily used as feed for pets like reptiles, birds, and fish, and for composting.
Why can't superworms be refrigerated?
Refrigerating superworms can harm them because they require a constant warm environment to stay active and healthy.
