Hornworms vs Silkworms: Which Feeder Is Better for Your Reptile?
Hornworms vs Silkworms: Which Feeder Worm Should You Choose?
Hornworms and silkworms are both premium feeder insects — soft-bodied, highly palatable, and nutritionally superior to crickets or mealworms. But they serve very different purposes in your reptile's diet. Hornworms are hydration feeders. Silkworms are low-fat protein feeders. Understanding the difference helps you use each one where it delivers the most value.
At All Angles Creatures, we sell both hornworms and silkworms and can speak to the strengths of each from direct experience breeding, shipping, and watching hundreds of reptiles devour them.
Nutrition Comparison
| Metric | Hornworms | Silkworms |
|---|---|---|
| Protein | 9% | 13% |
| Fat | 3% | 1% |
| Moisture | 85% | 83% |
| Calcium (mg/kg) | 464 | 177 |
| Ca:P Ratio | 3:1 (positive) | 0.8:1 |
| Chitin | None (soft body) | None (soft body) |
| Special compounds | None | Serrapeptase enzyme |
Hornworms: The Hydration Feeder
Hornworms are 85% water — essentially edible water bottles. Their primary value is delivering hydration directly through feeding, which is critical for species that are difficult to keep hydrated through misting or water dishes alone. Chameleons, blue tongue skinks, and any reptile showing signs of dehydration benefit enormously from hornworm feedings.
Hornworms also have a naturally positive 3:1 Ca:P ratio, meaning they contribute to calcium balance rather than depleting it. Their bright blue-green color triggers strong feeding responses in visually-oriented hunters like chameleons and bearded dragons.
- Best for: Hydration support, appetite stimulation, picky eaters
- Frequency: 1-3x per week as a supplement
- Not ideal as: Sole protein source — only 9% protein
- Storage: Room temperature, use within 1-2 weeks. They grow fast.
Silkworms: The Low-Fat Premium Feeder
Silkworms are the leanest feeder insect available at just 1% fat — 7x leaner than discoid roaches and 25x leaner than waxworms. For species prone to obesity, gout, or fatty liver disease — particularly chameleons and monitors — silkworms provide essential nutrition without the caloric burden. The serrapeptase enzyme found naturally in silkworms may support healthy inflammation response and immune function.
Silkworms are soft-bodied with zero chitin, making them ideal for juvenile reptiles and species with sensitive digestive systems. They can be offered to baby bearded dragons, juvenile chameleons, and small geckos without impaction risk.
- Best for: Low-fat nutrition, juveniles, gout-prone species, chameleons
- Frequency: 2-4x per week as part of rotation
- Not ideal as: Hydration source — 83% moisture is good but hornworms are better
- Storage: Room temperature (65-75°F), feed mulberry chow daily. Do not refrigerate.
Which Species Benefit Most from Each?
| Reptile | Hornworms | Silkworms |
|---|---|---|
| Chameleons | 1-2x/week for hydration | 2-3x/week — #1 chameleon feeder |
| Bearded Dragons | 1-2x/week as treat/hydration | 2-3x/week for variety |
| Leopard Geckos | 1x/week — large ones may be too big | 2x/week — excellent soft option |
| Blue Tongue Skinks | 2x/week — great hydration boost | 1-2x/week for variety |
| Ball Pythons | Not applicable (rodent feeders) | Not applicable |
Use Both for Maximum Benefit
Hornworms and silkworms are not competing feeders — they are complementary. A complete rotation includes discoid roaches for protein (daily), silkworms for low-fat nutrition (2-3x/week), hornworms for hydration (1-2x/week), and BSFL for calcium (1-2x/week).
