Choosing the Right Feeder Insects for Bearded Dragons: A Guide to Nutrition, Safety, and Variety
Bearded dragons are omnivorous reptiles that thrive on a varied diet. Insects are a key part of their nutritional intake — especially for younger dragons who require more protein for growth. But not all feeder insects are created equal. Choosing the wrong insects can lead to health issues like obesity, malnutrition, or metabolic bone disease (MBD).
Here’s a breakdown of the most common feeder insects, their pros and cons, and how they stack up when it comes to long-term bearded dragon health.
1. Dubia Roaches (Blaptica dubia)
Pros:
- Excellent calcium-to-phosphorus ratio (ideal for MBD prevention)
- High in protein, low in fat
- Doesn’t smell or climb smooth surfaces
- Easy to gut-load and breed
Cons:
- Slightly more expensive than crickets
- May not be available in all regions due to legal restrictions
Summary: Considered one of the best staple feeders due to their nutrition, ease of care, and safety.
2. Crickets (Acheta domesticus)
Pros:
- Widely available and inexpensive
- High in protein
- Stimulating for dragons to chase
Cons:
- Poor calcium-to-phosphorus ratio (must be dusted regularly)
- Can carry parasites or diseases if not sourced cleanly
- Noisy and smelly; can bite your pet if left uneaten
Summary: Affordable and fun to hunt, but must be gut-loaded and supplemented consistently.
3. Mealworms (Tenebrio molitor)
Pros:
- Easy to store
- Readily available
- Great for enrichment in small amounts
Cons:
- Hard outer shell (chitin) makes digestion difficult
- Poor calcium ratio
- High in fat
Summary: Use sparingly, especially with juveniles. Best for occasional treats, not as a staple.
4. Superworms (Zophobas morio)
Pros:
- High protein and stimulating to feed
- More digestible than mealworms
- Easy to keep at room temperature
Cons:
- High in fat
- Can bite if not properly subdued
Summary: Great as an occasional high-protein treat but should be rotated with leaner options.
5. Hornworms (Manduca sexta)
Pros:
- Extremely high moisture content (great for hydration)
- Low in fat
- Soft-bodied and easy to digest
Cons:
- Grow quickly (may outgrow appropriate feeding size)
- Costlier than other feeders
Summary: Excellent hydration support and gut-friendly, but better used a few times a week rather than daily.
6. Silkworms (Bombyx mori)
Pros:
- High in calcium and protein
- Soft-bodied and easy to digest
- Very low fat
Cons:
- Short shelf life
- Slightly more expensive and delicate to raise
Summary: One of the healthiest feeders available — perfect as a staple or rotational insect.
7. Black Soldier Fly Larvae (BSFL, Hermetia illucens)
Pros:
- Naturally high in calcium
- No dusting required
- Small and soft-bodied
Cons:
- Small size limits use to juveniles or as a supplement
- Can be expensive for larger portions
Summary: Great calcium boost and perfect for younger dragons or as a supplement to staple feeders.
8. Red Runner Roaches (Blatta lateralis)
Pros:
- Active and fast-moving (great for enrichment)
- Easy to digest
- High in protein
Cons:
- Can climb and escape enclosures
- Reproduce quickly — can become invasive if mishandled
Summary: Good for variety but best kept in escape-proof containers and used under supervision.
Health Concerns from Poor Feeder Choices
Feeding your dragon only mealworms or insects with poor calcium ratios can lead to Metabolic Bone Disease (MBD) — a serious condition where bones become weak and deformed. Insects high in fat like superworms and waxworms can also cause obesity and fatty liver disease if overused.
Tips to Avoid Health Issues:
- Always dust feeders with calcium (with D3 for indoor dragons) and multivitamins
- Offer a rotation of insects to provide full-spectrum nutrition
- Monitor your dragon’s weight, behavior, and stool quality
Final Thoughts
When choosing insects for your bearded dragon, think balance. Dubia roaches, silkworms, and BSFL make excellent staples. Crickets, superworms, and hornworms provide enrichment and variety, while mealworms and waxworms should remain rare treats.
By understanding the nutrition and behavior of each feeder insect, you’ll keep your bearded dragon healthy, active, and thriving.
