Feeding a chameleon: insects, gut-loading and carotenoid intake
Published by Planète Pets · managing editor: Clément Lacaille · how our guides are written
The chameleon is a strict insectivore that hunts with a projectile tongue rather than by chasing, a capture method that directly shapes which prey is worth offering in captivity. A nutrient-poor insect passes little nutritional value on to the animal that eats it, which is why gut-loading — feeding the insects themselves right before offering them — matters so much. All our food guides are gathered in the reptile food section, including gut-loading mealworms and superworms, a method that transfers directly to chameleon care.

Which insects should you favor by age?
- Crickets and fruit flies: suited to juveniles thanks to their small size, offered in modest but regular amounts several times a day.
- Stick insects and roaches: popular with adults, with a more favorable calcium-to-phosphorus ratio than some fatty worms.
- Mealworms and superworms: worth limiting in frequency for adults because of their chitinous shell, which is harder to digest in excess, but still useful occasionally.
Why does gut-loading change everything?
An insect fed for a few days on fresh vegetables, grains and a dedicated supplement carries far more vitamins and minerals to the animal that eats it than an insect from an undernourished feeder colony. This step remains the foundation of a balanced diet, even before the question of calcium or vitamin dusting.
What role do carotenoids play?
Carotenoids, found in certain orange and green vegetables fed to feeder insects during gut-loading, contribute to a chameleon's natural coloration and support its overall antioxidant status. A study by Fitze and colleagues, published in 2009 in Proceedings of the Royal Society B, shows in a model lizard species that carotenoid intake directly affects the intensity of skin coloration linked to immune status, a mechanism that carries over to chameleon nutrition principles in captivity.
Should you dust calcium and vitamins at every meal?
Dusting with calcium without vitamin D3 at most meals, plus a vitamin and D3 supplement only once or twice a week, remains the most common practice to avoid any excess, especially in an animal already exposed to suitable UVB lighting.
Frequently asked questions
Can a chameleon eat vegetables directly?
A few individuals occasionally nibble on leaves, but the species remains a strict insectivore: plant matter is mainly meant to feed the insects offered, not the animal itself.
How many insects per day for an adult?
The amount varies by size and species, often a handful of suitably sized insects per day, adjusted by watching the animal's body condition rather than following a single fixed number.
Does gut-loading replace calcium dusting?
No, the two complement each other: gut-loading enriches the insect beforehand, dusting adds a direct supplement at mealtime. Browse all our guides on the reptile hub.
