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)

InsectProteinFatNotes
CricketsHighLowMost accessible; must be gut-loaded
Dubia roachesHighModerateExcellent nutrition, low odor
Black soldier fly larvae (BSFL)ModerateModerateNaturally high in calcium
SilkwormsHighLowGreat nutrition, soft-bodied

Treat Feeders (1 to 2 times per week)

HornwormsModerateLowHigh water content, great for hydration
WaxwormsModerateVery highAddictive — use sparingly
SuperwormsHighHighOnly for large adult chameleons
Blue bottle fliesModerateLowStimulates hunting instinct

Avoid: wild-caught insects (pesticide risk), fireflies (toxic), and mealworms (hard chitin, poor nutrition).

Feeding Schedule by Age

AgeFrequencyQuantityInsect Size
0–3 monthsDaily10–15 insects1/4 inch
3–6 monthsDaily10–12 insects3/8 inch
6–12 monthsDaily8–10 insects1/2 inch
12+ monthsEvery other day5–7 insects3/4 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.

SupplementFrequencyPurpose
Calcium without D3Every feedingBone health, muscle function
Calcium with D32x per monthHelps absorb calcium (supplements UVB)
Multivitamin (with vitamin A)2x per monthOverall 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

  1. Overfeeding adults — leads to obesity, fatty liver disease, and shortened lifespan
  2. Skipping gut-loading — turns nutritious feeders into empty calories
  3. Wrong supplement schedule — too much D3 causes toxicity; too little causes MBD
  4. Offering only one feeder type — variety ensures complete nutrition
  5. Using a water bowl — chameleons ignore standing water and may develop bacteria

Frequently Asked Questions

How often should I feed my chameleon?
Juveniles (under 6 months) should eat 10 to 15 small insects daily. Sub-adults (6 to 12 months) eat 8 to 10 medium insects daily. Adults (over 12 months) eat 5 to 7 insects every other day. Overfeeding adults leads to obesity and liver problems.
Can chameleons eat fruits and vegetables?
Some chameleons, especially veiled chameleons, occasionally nibble on leafy greens, small pieces of squash, or berries. However, insects should make up at least 90% of their diet. Fruits and veggies are supplemental, not a staple.
Do chameleons drink from water bowls?
No. Chameleons do not recognize standing water as drinkable. They drink water droplets from leaves and surfaces. You must provide a drip system and mist the enclosure at least twice daily to keep your chameleon hydrated.
What happens if I don't gut-load feeder insects?
Feeder insects without gut-loading are nutritionally empty — essentially junk food. Your chameleon will develop nutritional deficiencies over time, including metabolic bone disease. Always gut-load insects 24 to 48 hours before feeding.
