Quick-Use Bearded Dragon Diet Chart by Age (Bugs, Veg & Calcium)

This is the “pin it on the fridge” version. Keep reading for details, brand/product picks, feeder comparisons, and troubleshooting.

Diet Chart Snapshot (Daily/Weekly Targets)

0–3 months (hatchling)

• •Bugs: 3–5 feeding sessions/day, as many as they’ll eat in 10–15 minutes each session (offer appropriate size)
• •Veg/greens: Offer daily (small amounts), but expect low intake
• •Calcium: 5x/week (with D3 if no UVB or weak UVB; otherwise plain calcium most days)
• •Multivitamin: 1–2x/week
• •Typical split: ~80% insects / 20% plants

3–6 months (juvenile)

• •Bugs: 2–3 sessions/day (10–15 minutes each)
• •Veg/greens: Daily, increasing amounts
• •Calcium: 4–5x/week
• •Multivitamin: 1–2x/week
• •Typical split: ~70% insects / 30% plants

6–12 months (sub-adult)

• •Bugs: 1–2 sessions/day or 5–7 insect meals/week (depends on body condition)
• •Veg/greens: Daily, should become a consistent part of diet
• •Calcium: 3–4x/week
• •Multivitamin: 1x/week
• •Typical split: ~50–60% insects / 40–50% plants

12+ months (adult)

• •Bugs: 2–4 insect meals/week (most healthy adults), adjust for weight/activity
• •Veg/greens: Daily (this is the main diet now)
• •Calcium: 2–3x/week
• •Multivitamin: 1–2x/month (or 1x/week if diet variety is limited)
• •Typical split: ~20–30% insects / 70–80% plants

Pro-tip: The “right” chart is the one that matches growth, body condition, poop quality, and energy—not just age. A fast-growing juvenile may need more bugs; a chunky adult needs fewer.

Before You Use Any Diet Chart: The 4 Rules That Make It Work

A bearded dragon diet chart by age is only accurate if the basics are right. If any of these are off, dragons often stop eating, won’t grow, or develop metabolic bone disease (MBD).

Rule 1: Correct UVB + Heat = Appetite + Calcium Use

Bearded dragons don’t “absorb calcium” well without strong UVB and proper basking temps.

• •UVB: A high-quality linear UVB tube (not a weak coil bulb). Common reliable picks:
• •Arcadia T5 HO 12% (Desert)
• •Zoo Med ReptiSun T5 HO 10.0
• •Basking surface temp: Typically 100–110°F for juveniles; many adults thrive around 100–105°F (measured with an infrared temp gun)
• •Cool side: ~75–85°F
• •Night: Usually 65–75°F is fine; heat only if it drops too low

If your dragon is “picky,” 50% of the time it’s actually husbandry, not the menu.

Rule 2: Size Your Feeders Correctly (Choking/Impaction Prevention)

A classic rule of thumb: feeder insects should be no longer than the space between your dragon’s eyes.

• •Too large = higher risk of choking, regurgitation, and impaction.
• •This matters most for hatchlings and small juveniles.

Rule 3: Hydration Comes from Greens (and Smart Bug Choices)

Many dragons barely drink from bowls. Hydration often comes from:

• •Rinsed leafy greens
• •Moist veg like squash or occasional cucumber (not as a staple)
• •Feeders with better moisture content (e.g., dubia roaches > superworms)

Rule 4: Variety Prevents Nutrient Gaps (and Picky Eaters)

Rotate at least 2–3 feeder types and 3–5 plant items weekly. You’ll get better poop, better growth, and fewer “my dragon refuses greens” battles.

Age-by-Age Feeding: Exact Bug/Veg/Calcium Plans

Let’s turn the chart into a practical routine you can actually follow.

0–3 Months: Hatchlings (High Protein, High Calcium Support)

Goal: Safe growth without overfeeding junk calories.

Bugs (Daily)

• •Frequency: 3–5 times/day
• •Quantity: Let them eat in 10–15 minutes
• •Best staples:
• •Dubia roaches (excellent nutrition, easy to digest)
• •Black soldier fly larvae (BSFL / “Phoenix worms”) (naturally high calcium)
• •Crickets (fine if gut-loaded and not left loose)

Avoid as staples: mealworms (tougher shells), superworms (too fatty/large), waxworms (treat only).

Veg/Greens (Daily Exposure Training)

Even if they only lick it, offer a tiny salad daily:

• •Finely chopped collard, mustard, or turnip greens
• •A little butternut squash (grated) for color and smell

Pro-tip: For hatchlings, chop greens extra fine and mix with a tiny bit of grated squash to “stick” to leaves.

Calcium + Vitamins

• •Calcium (most days): 5x/week
• •Multivitamin: 1–2x/week (light dusting)

Dusting method: Put insects in a cup, add a pinch of powder, swirl until lightly coated—don’t cake them white.

3–6 Months: Juveniles (Growth + Building Veg Habits)

Goal: Strong growth while gradually shifting toward more greens.

Bugs

• •Frequency: 2–3 times/day
• •Staples: dubia, BSFL, crickets
• •Add variety: silkworms (great), hornworms (hydrating, but treat-sized)

Veg/Greens

Make salad bigger and more consistent:

• •Greens base: collard, mustard, turnip, dandelion greens
• •Veg add-ins (rotate): butternut/acorn squash, bell pepper, green beans

Real scenario: Your 5-month-old is crushing roaches but ignores salad. Do this for 10 days:

1. Offer salad first, every morning (when they’re hungriest).
2. Wait 30–60 minutes, then offer bugs.
3. Add a topper 2–3x/week: bee pollen (tiny pinch) or a bit of BSFL mixed into salad.

This usually flips the “no greens” habit without starving them.

Calcium + Vitamins

• •Calcium: 4–5x/week
• •Multivitamin: 1–2x/week

6–12 Months: Sub-Adults (The Transition Phase)

Goal: Prevent an “overweight teen” while still supporting growth.

Bugs

• •Frequency: 5–7 insect meals/week (often 1/day, sometimes 1–2/day if lean and growing)
• •Staples: dubia, crickets, BSFL, silkworms

Veg/Greens

Daily salad becomes non-negotiable.

• •Make the salad the largest item on the menu.
• •Add more texture variety (thin ribbons of squash, chopped greens, occasional herbs like cilantro).

Common mistake: Keeping a sub-adult on hatchling-level insect volume. This often leads to:

• •Fat pads at the base of the tail getting thick
• •“Armpit bubbles” (fat deposits)
• •Lazy behavior
• •Runny stool from too much protein/fat

Calcium + Vitamins

• •Calcium: 3–4x/week
• •Multivitamin: 1x/week

12+ Months: Adults (Greens-First, Bugs as Protein Meals)

Goal: Lean, active adult with strong bone density and good hydration.

Bugs

Most healthy adults do well with:

• •2–4 bug meals/week
• •Portion depends on feeder type and dragon condition

Example: An adult “standard” bearded dragon (Pogona vitticeps), ~450–550g, active, good body condition:

• •3 bug meals/week (dubia or crickets)
• •Daily salads
• •Calcium 2–3x/week

If your adult is overweight, drop to 1–2 bug meals/week and emphasize leafy greens + squash.

Veg/Greens

Daily, large salad:

• •Staple greens: collard, mustard, turnip, dandelion
• •Veg rotation: squash, bell pepper, cactus pads (nopales), parsnip (small amounts)

Calcium + Vitamins

• •Calcium: 2–3x/week
• •Multivitamin: 1–2x/month (or weekly if diet variety is narrow)

Pro-tip: Adults that refuse greens often respond to “rotation + texture.” Switch from chopped to ribbons, add cactus pad strips, or lightly warm squash (not hot) to boost aroma.

Best Feeder Insects: Comparison, Pros/Cons, and When to Use Them

Here’s how the common bugs stack up in real-life use.

Staple Feeders (Use Regularly)

Dubia roaches

• •Pros: Great nutrition, less smell/noise than crickets, easy to gut-load, less likely to carry parasites (still buy from reputable sources)
• •Cons: Some dragons need time to accept them; banned in a few regions

Black soldier fly larvae (BSFL / Phoenix worms / CalciWorms)

• •Pros: Naturally calcium-rich; soft-bodied; amazing for picky babies and MBD prevention support
• •Cons: Smaller—some dragons get bored; can be pricey

Crickets

• •Pros: Easy to find; high activity triggers feeding response
• •Cons: Smell/noise, can bite, escape artists, lower “cleanliness,” need excellent gut-loading

Silkworms

• •Pros: Very nutritious, soft-bodied, good for hydration
• •Cons: More expensive; availability varies

Treat/Rotation Feeders (Use Sometimes)

Hornworms

• •Pros: Great hydration; good appetite stimulant during sheds
• •Cons: Low protein compared to staples; grow fast; treat-level

Superworms

• •Pros: Easy, enticing
• •Cons: Higher fat; can contribute to obesity; not for small juveniles due to size and tough exoskeleton

Waxworms

• •Pros: Extremely enticing for sick/anorexic dragons
• •Cons: Very fatty; can create “addiction” to treats—use sparingly

Feeders to Avoid or Use Carefully

• •Wild-caught insects: Pesticide/parasite risk
• •Fireflies/lightning bugs: Toxic
• •Mealworms for young dragons: Higher impaction risk due to tough chitin (some adults tolerate them, but there are better options)

Best Greens and Veggies: What’s Staple vs Occasional

A strong plant routine is where adult dragons thrive. Think: high calcium, high fiber, low oxalate most days.

Staple Greens (Top Picks)

Rotate these as the “base”:

• •Collard greens
• •Mustard greens
• •Turnip greens
• •Dandelion greens (from safe sources)
• •Endive/escarole

Great Veggie Add-Ins (Rotate)

• •Butternut, acorn, or spaghetti squash
• •Bell pepper (variety of colors)
• •Green beans
• •Cactus pads (nopales) (excellent texture and hydration)

Occasional Items (Small Amounts)

• •Carrot (more sugar)
• •Cucumber (mostly water; can loosen stool)
• •Fruit (many vets now recommend very little due to sugar and oral health; if used, tiny portions occasionally)

Common Plant Mistakes

• •Too much spinach/kale as the main green: not “poison,” but not ideal as a staple because of oxalates/goitrogens and mineral balance.
• •Iceberg lettuce: watery, low nutrition.
• •Pellets as the main diet: fine as a backup, not as the foundation.

Pro-tip: If you only choose one green to keep on hand all the time, pick collard greens and rotate others in when you can.

Calcium and Supplement Schedule (Simple, Safe, and Age-Based)

This is where many well-meaning owners accidentally cause problems—either under-supplementing (MBD risk) or overdoing it.

What to Use

• •Calcium without D3: Best choice for most dragons with proper UVB.
• •Calcium with D3: Helpful if UVB is absent/temporary or confirmed inadequate (work toward fixing UVB rather than relying on D3 long-term).
• •Multivitamin: A reptile-specific vitamin with vitamin A in safe form.

Product-style recommendations (reliable, commonly used):

• •Calcium powders: Rep-Cal Calcium, Zoo Med Repti Calcium
• •Multivitamins: Rep-Cal Herptivite, Zoo Med Reptivite (choose a version appropriate to your setup)

How to Dust Correctly (Step-by-Step)

1. Place feeders in a smooth-sided cup or bag.
2. Add a small pinch of calcium (more isn’t better).
3. Swirl/shake gently until insects are lightly coated.
4. Feed immediately (powder falls off over time).

Age-Based Schedule (Typical)

• •Hatchlings: calcium 5x/week; multivitamin 1–2x/week
• •Juveniles: calcium 4–5x/week; multivitamin 1–2x/week
• •Sub-adults: calcium 3–4x/week; multivitamin 1x/week
• •Adults: calcium 2–3x/week; multivitamin 1–2x/month (or weekly if limited variety)

Special cases:

• •Gravid (egg-laying) females often need closer guidance and may benefit from more calcium support—this is a good time to consult an exotics vet for individualized dosing and to rule out egg binding risk.

Step-by-Step Daily Feeding Routine (Works for Most Homes)

Consistency beats “perfect” foods. Here’s a routine that fits busy schedules.

Morning Routine (Best for Appetite and Digestion)

1. Lights on (UVB + basking) and allow 30–60 minutes to warm up.
2. Offer a fresh salad (greens base + 1 veg).
3. Remove wilted salad after a few hours.

Bug Feeding Routine (By Age)

• •Hatchlings/Juveniles: offer bugs mid-morning and mid-afternoon (and a third feeding for hatchlings if needed)
• •Adults: pick 2–4 days/week for bug meals; keep greens daily

Gut-Loading and Hydration (Do This or Your Bugs Are “Empty Calories”)

Gut-load crickets/roaches with:

• •Dark leafy greens
• •Squash
• •Commercial gut-load (reptile/insect-specific)

Avoid feeding insects only potato or cereal—your dragon gets a nutrient-poor meal.

“Breed” and Morph Examples: How Different Bearded Dragons May Eat

Most pet beardies are Pogona vitticeps (central bearded dragon). Within that, morphs and special types can influence feeding logistics, not the basic nutrition rules.

Standard vs “Giant German” Lines (Bigger Body, Same Principles)

• •Larger dragons may eat larger portions, but adults still should be greens-first.
• •Watch body condition; “big frame” isn’t the same as “overweight.”

Leatherback/Silkback (Skin Differences Affect Care)

• •Silkbacks (very reduced scales) can have more delicate skin and may shed differently; keep hydration and humidity appropriate.
• •Diet fundamentals stay the same, but owners often overuse hornworms to “hydrate.” Better: greens + proper enclosure conditions.

Rescues with Stunting (Common Real Scenario)

A rescued juvenile that’s small for age may need:

• •Confirmed temps/UVB
• •Parasite check (fecal exam)
• •A careful ramp-up of high-quality staples (dubia, BSFL, silkworms) and consistent calcium

Stunted dragons can still thrive, but they need medical + husbandry support, not just “more food.”

Common Mistakes (and Exactly How to Fix Them)

Mistake 1: Too Many Bugs for Too Long

What you see: adult refuses greens, gaining weight, lazy. Fix: reduce bug meals to 2–3x/week, offer salad first daily, rotate greens.

Mistake 2: Feeding “Big Treat Worms” as Staples

What you see: picky eater, soft stool, obesity. Fix: treat worms become once-weekly or less; shift to dubia/BSFL.

Mistake 3: Calcium Without UVB (or Bad UVB)

What you see: tremors, soft jaw, weak grip, poor growth (possible MBD). Fix: upgrade UVB to a high-output linear tube, verify distances and replace bulbs on schedule; continue calcium support and see an exotics vet.

Mistake 4: No Salad Routine Until Adulthood

What you see: “My adult won’t touch greens.” Fix: start daily salads from hatchling stage, use toppers sparingly, and be consistent.

Mistake 5: Leaving Crickets Loose in the Enclosure

Crickets can bite and stress your dragon, especially at night. Fix: feed in a bin/tub or supervise; remove uneaten insects.

Pro-tip: If your dragon is suddenly not eating, don’t immediately switch foods. First confirm basking temps, UVB age/type, and signs of shedding or brumation.

Troubleshooting: Adjust the Chart to Your Dragon (Not the Calendar)

If Your Dragon Won’t Eat Greens

Try this 7-day plan:

1. Salad first every morning.
2. Reduce bug portion slightly (don’t starve juveniles—just don’t “free feed”).
3. Add variety: collard + endive + squash ribbons.
4. Use a tiny pinch of bee pollen 2–3 days, then stop.
5. Offer movement: hand-feed a green “wiggle” or use tongs.

If Stools Are Runny

Common causes:

• •Too many hornworms/watery veg
• •Sudden diet change
• •Stress, parasites, or incorrect temps

Fix:

• •Return to staples (collard + squash; dubia/BSFL)
• •Verify basking temp
• •If it persists >1–2 weeks or there’s weight loss, get a fecal exam.

If You Suspect Obesity

Signs:

• •Thick tail base and large fat pads behind head
• •“Armpit bubbles”
• •Low activity

Fix:

• •Adult: 1–2 bug meals/week for a while
• •Increase greens, reduce fatty feeders
• •Encourage movement (safe climbing, supervised out time)
• •Consider a vet check for underlying issues

If Your Dragon Is Underweight or Not Growing

Check:

• •UVB quality and placement
• •Parasites (very common)
• •Feeder size and quantity
• •Stress (tank too small, poor hides, too much handling)

Shopping List: Practical Product Recommendations (What’s Worth Buying)

You don’t need a ton of gadgets—just the right core tools and dependable foods.

Must-Haves

• •Infrared temperature gun (accurate basking surface readings)
• •Digital probe thermometer (ambient temps)
• •High-quality linear UVB fixture + bulb (Arcadia or ReptiSun T5 HO)
• •Calcium powder + reptile multivitamin

Feeding Convenience Items

• •Escape-proof feeding dish for roaches/BSFL
• •Salad chopper or kitchen shears dedicated to reptile food
• •Bug bin/tub for controlled feeding

Feeder Source Tips

• •Buy feeders from reputable breeders/suppliers.
• •Avoid dusty, dead-on-arrival heavy shipments—poor feeder quality = poor nutrition for your dragon.

Final Notes: Your Best “By Age” Chart Is One You Recheck Monthly

Use the bearded dragon diet chart by age as your baseline, then adjust based on:

• •Body condition
• •Growth rate
• •Activity level
• •Stool consistency
• •Seasonal behavior (some adults reduce appetite during brumation-like periods)

If you want, tell me your dragon’s age, approximate weight, current feeder types, UVB bulb model, and basking surface temp—then I can translate this chart into a personalized weekly menu (with exact bug meal days and salad rotation).
