Feeder Insects 101: Nutritional Value & Benefits for Reptiles
Choosing the right feeder insects is one of the most important parts of reptile care. Different feeders offer different levels of protein, fat, calcium, and moisture, which means variety matters. A healthy feeding routine should match your reptile’s species, size, age, condition, and natural diet.
At Wildrose Reptile Ranch, we believe feeder insects are more than just “food.” They support hydration, growth, bone health, digestion, enrichment, and natural hunting behaviours. Here is a simple guide to some popular feeder options and what each one brings to the table.
Why Feeder Variety Matters
No single feeder is perfect for every reptile all the time. Some feeders are better as staples, while others are best used as treats or for specific needs like hydration, appetite support, or weight gain.
A varied feeder rotation can help provide a better balance of nutrients while keeping your reptile interested in food. It also encourages more natural feeding behaviour, especially for species that enjoy chasing or hunting live prey.
Crickets
Nutritional profile:
Protein: High
Fat: Low
Calcium: Low
Moisture: Moderate
Crickets are a great staple feeder for many reptiles. They are active, easy for reptiles to hunt, and help encourage natural feeding behaviour. Because they are lower in calcium, they should usually be offered with proper supplementation and gut loading.
Mealworms
Nutritional profile:
Protein: Moderate
Fat: Moderate
Calcium: Low
Moisture: Low
Mealworms are easy to keep, easy to feed, and widely accepted by many reptiles. They are best used in moderation and as part of a varied diet. Their lower moisture and calcium levels make them less ideal as the only feeder source.
Superworms
Nutritional profile:
Protein: Moderate
Fat: Higher
Calcium: Low
Moisture: Moderate
Superworms are larger, more active feeders that work well for bigger reptiles. They are excellent for enrichment and appetite stimulation because their movement often grabs attention quickly. Due to their higher fat content, they are best used alongside leaner feeder options.
Black Soldier Fly Larvae
Nutritional profile:
Protein: Moderate
Fat: Low
Calcium: High
Moisture: Moderate
Black soldier fly larvae are naturally high in calcium, making them an excellent choice for supporting bone health. They are especially useful in a feeder rotation for reptiles that need extra calcium support. Their soft bodies also make them easy for many animals to eat.
Silkworms
Nutritional profile:
Protein: High
Fat: Low
Calcium: Moderate
Moisture: High
Silkworms are soft-bodied, nutritious, and easy to digest. They are a fantastic feeder option for many reptiles, especially when you want something high in protein but lower in fat. Their moisture content also makes them a helpful addition to a balanced feeding routine.
Hornworms
Nutritional profile:
Protein: Moderate
Fat: Low
Calcium: Low
Moisture: Very High
Hornworms are excellent for hydration and can be helpful for boosting appetite. Their bright colour and movement often make them exciting for reptiles to eat. Because they are very high in moisture, they are commonly used as a treat feeder rather than a main staple.
Waxworms
Nutritional profile:
Protein: Low
Fat: Very High
Calcium: Low
Moisture: Moderate
Waxworms are best used as an occasional treat. Their very high fat content can be helpful for reptiles that need to gain condition, but they should not make up a large part of the regular diet for most animals. Think of them as a special snack, not a staple feeder.
Final Feeding Tips
The best feeder plan depends on your reptile’s species, age, size, appetite, and overall condition. Staples like crickets, black soldier fly larvae, silkworms, and other balanced feeders can form the foundation of a good diet, while higher-fat options like waxworms and superworms should be used with more intention.
For best results, offer variety, gut load feeders when appropriate, and use calcium or vitamin supplementation based on your reptile’s needs.
