Silkworms are quietly one of the best feeder insects available for bearded dragons. They are soft, slow-moving, packed with protein and moisture, low in fat, and gentler on mineral balance than most common feeders. Many experienced keepers and reptile vets rank silkworms among the top choices, especially for growing dragons, fussy eaters, and dragons that need a nutrient boost.

The verdict: Excellent staple. Yes, feed silkworms freely. They are high in protein, low in fat, very hydrating, soft-bodied, and have one of the better calcium-to-phosphorus ratios among feeder insects. Light calcium dusting still applies for growing dragons.

Silkworm nutrition for bearded dragons

Silkworms, the larvae of the moth Bombyx mori, are a standout feeder. They are high in protein yet very low in fat, and they carry a high water content that helps with hydration. Their soft bodies mean very little chitin, so they are easy to digest and a smart choice for young dragons whose digestive systems are still developing. They also contain serrapeptase, an enzyme some keepers value, though the main appeal is simply their clean, lean profile.

Where silkworms really shine is mineral balance. Their calcium-to-phosphorus ratio is more favorable than crickets, mealworms, or superworms, sitting closer to neutral rather than heavily phosphorus-loaded. They still lean slightly toward phosphorus, so a light calcium dusting for growing dragons keeps things in the safe zone.

How to feed silkworms

  • Size each silkworm no longer than the space between your dragon's eyes.
  • Offer them in a shallow dish or by hand, since they move slowly and will not run off like crickets.
  • Lightly dust with calcium for growing dragons, following your usual supplement schedule.
  • Feed them straight from the container, as their mulberry diet already makes them nutritious.
  • Remove any uneaten worms so they do not dry out or spoil in the enclosure.

How often to feed silkworms by life stage

Because silkworms are lean, they can play a large role in the insect portion of the diet without the fat worries of treat feeders.

  • Hatchlings and babies (0 to 5 months): a main insect offered several times a day, eaten freely in short sessions.
  • Juveniles (5 to 18 months): a frequent insect once or twice a day as greens grow in the diet.
  • Adults (18 months and up): a small handful a few times a week within an insect rotation, alongside a diet that is roughly 80 percent greens.

Risks to watch for

  • Sizing: even soft worms can cause impaction if far too large, so respect the eye-gap rule.
  • Spoilage: silkworms are delicate and can die or mold in poor conditions, so buy amounts you will use within a week or two.
  • Cost and availability: they are pricier and less shelf-stable than crickets, which is why many keepers use them alongside other feeders rather than alone.

A balanced bearded dragon diet is roughly 80 percent insects for babies and 80 percent leafy greens for adults. Silkworms are one of the finest insects you can build that protein portion around, though variety still beats relying on any single feeder. Pair them with other gut-loaded insects from our feeder insects guide, and see the full feeding picture on our diet hub.

Frequently Asked Questions

Are silkworms good for bearded dragons?

Yes, silkworms are one of the best feeder insects you can offer. They are high in protein, low in fat, very high in moisture, soft-bodied, and have a better calcium-to-phosphorus ratio than most insects. That combination makes them an excellent staple or near-staple for dragons of all ages, including picky eaters and dragons recovering from illness.

How many silkworms can a bearded dragon eat?

Because silkworms are lean and gentle, you can feed them generously. Babies and juveniles can eat them as a main insect several times a day, sized to the dragon. Adults can have a small handful a few times a week as part of an insect rotation. Since they are low in fat, they are harder to overfeed than treat insects like waxworms.

What size silkworm should I feed?

Match the silkworm to your dragon using the space between the eyes as your maximum length. Silkworms grow from tiny hatchlings to large worms several centimeters long, so you can buy them sized for your dragon. Babies take small silkworms, while a large adult dragon can handle bigger ones. When unsure, choose the smaller size.

Do silkworms still need calcium dusting?

Silkworms have a better calcium ratio than crickets or mealworms, but they still tilt slightly toward phosphorus, so dusting growing dragons with calcium is still smart. You will need to dust less heavily than with poorer feeders. Calcium with D3 and a multivitamin should still appear on your normal supplement schedule.

What do silkworms eat and can my dragon eat them right away?

Silkworms eat mulberry leaves or a prepared mulberry-based chow, which is part of why they are so clean and nutritious. You can feed them to your dragon straight from the container. There is no need to gut load a fresh silkworm heavily since its mulberry diet already makes it a wholesome feeder, though dusting still applies.

Are silkworms hard to keep alive?

Silkworms are a little more delicate than crickets or roaches. They need their mulberry chow, gentle warmth, and clean, dry conditions, and they do not tolerate cold or dampness well. Many keepers buy them in smaller batches sized to use within a week or two rather than maintaining a long-term colony.
