They're more of a treat than a nutritional food. Theyre very fatty so you dont want to give them many, especially a 3 month old. Maybe 1 every other day.
wax worms contains lots of fat.
Good for emaciated chameleon that need to regain weight.
But, as staple, it is not favorable.
It is the junk food of the insect world.
My chameleon never has access to waxworms and mealworms.
