What Do Chameleons Eat? Feeding Guide & Schedule [2026]
Published March 27, 2026 · By ExoPetHub Team
Learn what chameleons eat, how often to feed them, and the correct calcium and vitamin dusting schedule. Covers gut-loading, feeder insects, and hydration.
Chameleon Diet Overview
Chameleons are primarily insectivores that eat a variety of live feeder insects. Proper nutrition depends on three pillars: offering the right insects, gut-loading those insects beforehand, and dusting them with calcium and vitamins on a precise schedule.
Getting the diet right is one of the most impactful things you can do for your chameleon's long-term health.
Best Feeder Insects
Not all insects are equal. Offer variety to ensure balanced nutrition.
Staple Feeders (daily rotation)
| Insect | Protein | Fat | Notes |
|---|---|---|---|
| Crickets | High | Low | Most accessible; must be gut-loaded |
| Dubia roaches | High | Moderate | Excellent nutrition, low odor |
| Black soldier fly larvae (BSFL) | Moderate | Moderate | Naturally high in calcium |
| Silkworms | High | Low | Great nutrition, soft-bodied |
Treat Feeders (1 to 2 times per week)
| Insect | Protein | Fat | Notes |
|---|---|---|---|
| Hornworms | Moderate | Low | High water content, great for hydration |
| Waxworms | Moderate | Very high | Addictive — use sparingly |
| Superworms | High | High | Only for large adult chameleons |
| Blue bottle flies | Moderate | Low | Stimulates hunting instinct |
Avoid: wild-caught insects (pesticide risk), fireflies (toxic), and mealworms (hard chitin, poor nutrition).
Feeding Schedule by Age
| Age | Frequency | Quantity | Insect Size |
|---|---|---|---|
| 0–3 months | Daily | 10–15 insects | 1/4 inch |
| 3–6 months | Daily | 10–12 insects | 3/8 inch |
| 6–12 months | Daily | 8–10 insects | 1/2 inch |
| 12+ months | Every other day | 5–7 insects | 3/4 to 1 inch |
Rule of thumb: feeder insects should be no wider than the space between your chameleon's eyes.
Feeding Method
- Free-range feeding: release insects into the enclosure and let your chameleon hunt — this encourages natural behavior
- Cup feeding: place insects in a smooth-sided cup attached to a branch — useful for tracking intake
- Tong feeding: offer insects with soft-tipped tongs — builds trust but do not overuse
Gut-Loading: The Key to Nutrition
Gut-loading means feeding nutritious food to your insects 24 to 48 hours before offering them to your chameleon. The nutrients in the insect's gut transfer directly to your chameleon.
Best gut-load foods: dark leafy greens (collard, mustard, dandelion greens), squash, sweet potato, carrots, and commercial diets (Repashy Bug Burger). Avoid spinach (binds calcium), iceberg lettuce, and dog/cat food.
Calcium and Vitamin Dusting Schedule
Proper supplementation prevents metabolic bone disease (MBD), the most common and devastating health issue in captive chameleons.
| Supplement | Frequency | Purpose |
|---|---|---|
| Calcium without D3 | Every feeding | Bone health, muscle function |
| Calcium with D3 | 2x per month | Helps absorb calcium (supplements UVB) |
| Multivitamin (with vitamin A) | 2x per month | Overall health, eye health |
Lightly dust insects by placing them in a bag with a pinch of powder and shaking gently. Do not combine calcium with D3 and multivitamin on the same feeding day — alternate them across the month.
Hydration: Misting and Dripping
Chameleons do not drink from water bowls. They lick water droplets from leaves and branches. Proper hydration requires:
- Misting: 2 to 3 times daily for 2 to 3 minutes using a pump sprayer or automated system (MistKing, Monsoon)
- Drip system: position a dripper so water falls onto leaves near favorite perching spots
- Use purified or dechlorinated water for both systems
Signs of Dehydration
- Sunken eyes, wrinkled skin, orange urates (should be white), lethargy
If your chameleon shows dehydration signs, increase misting frequency and offer hornworms for extra moisture. Veiled chameleons may also nibble leafy greens (collard greens, mustard greens) and small pieces of fruit — other species rarely eat plant matter.
Common Feeding Mistakes
- Overfeeding adults — leads to obesity, fatty liver disease, and shortened lifespan
- Skipping gut-loading — turns nutritious feeders into empty calories
- Wrong supplement schedule — too much D3 causes toxicity; too little causes MBD
- Offering only one feeder type — variety ensures complete nutrition
- Using a water bowl — chameleons ignore standing water and may develop bacteria
