A baby bearded dragon and an adult need almost opposite diets. Enter your dragon’s age to see the right balance of insects and greens, how often to feed, and a sample week showing which days to dust insects with calcium or multivitamin.

Feeding chart

Age Insects / plants Insect feedings Greens
0–3 months ~80% / 20% 3 times a day Finely chopped, daily
3–6 months ~75% / 25% 2–3 times a day Daily
6–12 months ~65% / 35% 1–2 times a day Daily
12–18 months ~50% / 50% Once a day or every other day Daily
18+ months (adult) ~20% / 80% 2–3 times a week Daily — the main diet

How much to feed

Rather than counting, most keepers and reptile vets use a time limit: offer insects for 10–15 minutes, then remove what’s left. Babies may eat dozens of small insects a day; adults often lose interest after 10–20. Watch body condition — a healthy adult has a rounded belly but no fat bulging at the base of the tail or behind the eyes.

Insect size and supplements

  • Insect size: never wider than the space between your dragon’s eyes. Oversized insects are a leading cause of impaction and choking.
  • Calcium: dust insects with calcium at most feedings for growing dragons, and 2–3 times a week for adults.
  • Multivitamin: about once a week at all ages.
  • D3: with strong, correctly placed UVB, dragons make their own. Many keepers use calcium without D3 most days and calcium with D3 once or twice a week — follow your vet’s advice for your setup.

FAQ

My adult dragon won’t eat greens. What should I do?

Offer greens first thing in the morning before any insects, chop them small and mix in a few colorful items like squash or bell pepper. Cutting back insects gradually is often enough.

Can I feed insects every day to an adult?

A small portion is fine for some dragons, but adults fed insects daily commonly become overweight. Most do best with insects two or three times a week.

Should I gut-load insects?

Yes. Feed crickets and roaches fresh greens and a quality gut-load for 24 hours beforehand — your dragon gets the nutrition the insect ate.
