Juvenile bearded dragon eating dubia roaches from a feeding dish

What to Feed Your Bearded Dragon at Every Age

Here’s the whole feeding program in one paragraph: babies eat insects 2–3 times a day (about 80% insects, 20% greens); juveniles get insects twice daily as greens take over; adults eat a fresh salad every day and insects every other day (about 20% insects, 80% greens). Dust the insects with calcium on the schedule below.

Read this before you buy another tub of crickets: the most expensive feeding mistake isn’t the wrong insect — it’s the wrong dusting schedule. Skipping calcium causes metabolic bone disease, the #1 nutritional disease in pet bearded dragons, and it’s entirely preventable with the routine below.

Feeding schedule by age

Baby schedule — growth mode

  • Insects: 3× daily, 10–15 minute sessions — as many as they’ll chase
  • Greens: small fresh salad daily (mostly ignored — offer anyway)
  • Calcium: dust insects daily
  • Multivitamin: 1–2× per week
🐛 Tip: count sessions, not insects. A baby can take dozens of small dubias in 15 minutes at peak growth — that’s exactly what should happen.

Juvenile schedule — the transition

  • Insects: 2× daily, 10–15 minute sessions
  • Greens: fresh salad daily — they’ll start nibbling
  • Calcium: dust insects 4–5× per week
  • Multivitamin: 1–2× per week
🥬 Tip: this is when salad strikes happen — juveniles refusing all greens for weeks. Keep offering; most convert around 12–18 months.

Adult schedule — maintenance

  • Insects: every other day, a modest portion
  • Greens: big fresh salad every single day
  • Calcium: dust insects 2–3× per week
  • Multivitamin: 1× per week
⚠️ Tip: a salad-only adult slowly loses condition over months. They still need insects every other day for protein.

Babies are insect machines — protein for growth.

Count sessions, not insects. A baby might eat dozens of small dubias in 15 minutes — that’s the point. And prey size rule never changes: nothing wider than the space between the dragon’s eyes.

Did you know?
Dust the insects, not the salad. Calcium powder sticks to a moving dubia far better than it sticks to a collard leaf — and the dragon actually eats the insects.

Did you know?
Gut-load your feeders 24 hours before offering them. A dubia stuffed with squash and greens is a multivitamin with legs; an unfed dubia is just a shell.

What a real feeding day looks like

Schedules on paper are tidy. Real life is messier, so here’s what it actually looks like:

Baby day (under 4 months): Lights on at 7. First insect feeding around 8:30 — as many appropriately-sized dubias as they’ll chase in 10–15 minutes. Fresh salad goes in by 9 and stays all day (they’ll mostly ignore it; that’s fine, it’s about exposure). Second insect round at 1, third at 5. Lights out at 7–8. Total active feeding time for you: about 40 minutes spread across the day.

Adult day (18+ months): Fresh salad in the morning, swapped for a fresh one if it wilts. Insects every other day — a dozen or so dubias or a handful of BSFL, dusted with calcium. That’s genuinely it. Adults are the easy mode everyone promised you at the pet store.

Gut-loading: the step everyone skips

Your dragon is only as nutritious as what its insects ate. “Gut-loading” just means feeding your feeders well for 24 hours before offering them — fresh greens, carrots, sweet potato, and a slice of orange for moisture. The sad, starved crickets from the pet store cup are nutritionally empty boxes. A well-fed dubia is a multivitamin with legs. This single habit does more for your dragon’s health than any supplement powder, and it costs you nothing but the vegetable scraps you already have.

Safe foods chart

Staple greens (feed freely): collard greens, mustard greens, dandelion greens, turnip greens, butternut squash, acorn squash.

Occasional (a few times a week): bell peppers, blueberries, strawberries, mango, green beans, prickly pear pads.

Rare treats: banana, watermelon — sugary, so tiny amounts.

Never feed: fireflies (a single one can be lethal), avocado, rhubarb, iceberg lettuce (zero nutrition), citrus, wild-caught insects (pesticides).

Did you know?
Bearded dragons rarely drink from a water bowl. They get most of their moisture from food — which is why gut-loaded insects and fresh greens matter more than the dish in the corner. Drip water on the snout if you’re worried about hydration.

Quick answers

How many insects does a baby need per day?

Don’t count — time it. Three 10–15 minute sessions of as-many-as-they’ll-chase. For tiny dubias that can mean 30–60 a day at peak growth. Appetite varies; the session method self-adjusts.

Can an adult live on salad alone?

Almost, but not quite. Adults still need insects every other day for protein. A salad-only adult slowly loses condition over months.

Does the calcium need D3?

With a proper linear UVB tube, plain calcium most days is the standard routine, plus a D3-containing calcium once or twice a week as backup. Without reliable UVB, nothing in this schedule works — fix the lighting first.

Can bearded dragons eat fruit every day?

No. Fruit is a treat — a few times a week at most. Daily fruit means too much sugar and a dragon that refuses its greens.
