What Do Chameleons Eat? A Complete Nutrition Guide

Chameleons are fascinating creatures known for their color-changing skin and long, sticky tongues. To keep these exotic reptiles healthy in captivity, providing a diet that mimics their natural habitat is crucial. Unlike some other lizards, most chameleons are strictly insectivorous, meaning their diet revolves around live prey.

The Core Diet: Best Insects for Chameleons

Insects provide the protein and moisture chameleons need to thrive. Variety is key to preventing “hunger strikes” and ensuring a wide range of nutrients.

1. Staple Insects (Daily Feeding)

These should make up the bulk of your chameleon’s diet:

  • Crickets: The most common feeder insect. They are active and trigger the chameleon’s hunting instinct.
  • Dubia Roaches: Highly nutritious, easy to digest, and contain more protein than crickets.
  • Silkworms: Excellent source of calcium and protein; they are also very hydrating.
  • Hornworms: Great for hydration, but should be rotated as they grow very fast.

2. Occasional Treats

These are higher in fat and should be given only once or twice a week:

  • Mealworms & Superworms: These have a tough outer shell (chitin), so feed them sparingly to avoid impaction.
  • Waxworms: Very high in fat; perfect for “fattening up” a rescued or thin chameleon.
  • Black Soldier Fly Larvae: Naturally high in calcium.

Do Chameleons Eat Fruits and Vegetables?

While most chameleons are insectivores, some species—specifically Veiled Chameleons—are known to nibble on plant matter for extra hydration and fiber.

  • Safe Greens: Mustard greens, collard greens, and dandelion leaves.
  • Safe Fruits: Small pieces of papaya, melon, or berries (very rarely).
  • Note: If you have a Panther Chameleon, they rarely eat plants, so focus almost entirely on insects.

The Secret to Health: Gut-Loading & Supplements

A feeder insect is only as nutritious as the food it eats. This process is called “Gut-loading.”

  • Gut-Loading: Feed your insects high-quality vegetables (carrots, squash, leafy greens) 24 hours before offering them to your chameleon.
  • Calcium Powder: Dust your insects with calcium powder (without D3) at almost every feeding.
  • Vitamin D3 & Multivitamins: Use these sparingly (usually twice a month) to prevent metabolic bone disease.

Hydration: They Don’t Use Water Bowls!

One of the biggest mistakes new owners make is providing a water bowl. Chameleons do not recognize standing water.

  • Misting: Mist the enclosure 2-3 times a day so the chameleon can drink droplets off the leaves.
  • Dripper System: A slow-release dripper ensures they have access to water throughout the day.

Frequently Asked Questions (FAQs)

  • Juveniles: 10-12 small insects daily to support growth.
  • Adults: 5-7 large insects every other day. Overfeeding adults can lead to obesity and organ stress.

No. Wild insects often carry parasites or may have ingested pesticides that are lethal to chameleons. Always use captive-bred feeders.

This could be due to “food boredom” (try a different insect), incorrect temperatures, or stress. If the refusal lasts more than a few days, consult a vet.

While they can eat small, non-toxic spiders in the wild, it is safer to stick to commercially available feeder insects to avoid venomous bites or parasites.

Conclusion

Feeding a chameleon is about more than just tossing in a few crickets. By focusing on a variety of gut-loaded insects, proper calcium supplementation, and ensuring they have plenty of leaf-dripping water, you can help your pet live a long and vibrant life.
