What do Jackson's chameleons eat?

The short answer

Jackson's chameleons are insectivores, and with chameleons the quality of the insect matters as much as the species of insect. Gut-loading is not optional. Hydration is equally central: chameleons drink moving water from leaves, and a dehydrated chameleon stops eating long before anything else looks wrong.

Where good sources disagree

Care sheets do not all say the same thing, and pretending otherwise helps nobody. These are the real points of difference between the sources cited at the foot of this page, and what we think the safe reading is.

Supplement frequency.

Chameleon supplementation schedules vary considerably between sources, partly because the right amount of vitamin A and D3 depends on UVB provision and on the base diet. The shared caution is the opposite of the usual one: with chameleons, over-supplementation is as real a risk as under-supplementation.

What most jackson's chameleon feeding advice gets wrong

Hydration is the first thing to check when a chameleon stops eating.

Chameleons drink moving droplets from foliage and typically ignore standing water. A dripper or a misting schedule is core equipment rather than an accessory. Sunken eyes and orange-tinted urates indicate dehydration, and appetite usually falls before either becomes obvious.

Gut-load, then dust, in that order.

A chameleon eating poorly fed crickets is eating very little of value regardless of what powder is on the outside. Feeding the insects a quality diet for 24 to 48 hours before offering them does more for the chameleon than any supplement schedule.

Live-bearing changes the demands.

Jackson's chameleons give birth to live young rather than laying eggs, and gravid females have substantially higher nutritional and calcium requirements. A female losing condition during gestation needs veterinary input rather than simply more food.

Common questions

What do Jackson's chameleons eat?

Live insects: crickets, dubia roaches, silkworms, hornworms and black soldier fly larvae, gut-loaded for 24 to 48 hours before offering and dusted with calcium on an appropriate schedule. They do not eat plant matter in any meaningful quantity.

How do Jackson's chameleons drink?

From moving water droplets on leaves, supplied by a dripper system or regular misting. They generally ignore standing water bowls. Because dehydration suppresses appetite early, hydration is effectively part of the feeding routine.

How often should I feed a Jackson's chameleon?

Juveniles daily, adults daily to every other day, with roughly five to ten appropriately sized insects per feeding. Gravid females need more, since this species gives birth to live young rather than laying eggs.
