...you are rubbing some of us the wrong way in just the few days you have been posting. You really need to re-read your posts and realize what they will sound like to readers before you hit that enter key. Personally, I resent your crack about my "holier than thou tangent" as I was very careful to let it be known that it was only MY opinion and I was not foisting it upon you or anyone else. Your comment alone makes you seem a bit high and mighty.
That said, I will give you the information you are looking for…again, as I gave you it in my previous post. You will not find a definitive answer b/c they would not only choose one type of insect. They have a plethora to choose from and therefore would pick and choose on availability, state of hunger, etc. Few insectivorous creatures eat only one type of insect (though there are some) and some chameleons are omnivores and eat fruit, etc. as well. They, like us, prefer variety.
a quote from http://www.skypoint.com/members/mikefry/food.html:
The diet of a wild chameleon is made up of countless species of insects and other small invertebrates as well as vertebrates. Many chameleons are also reported to eat some wild berries and other vegetable matter. Some of the larger chameleon species will eat small birds, reptiles, and mammals. It is therefore logical to assume that chameleons have evolved to consume a diet that is highly diverse and complex.
from: http://www.reptilevet.com/chamel.htm
Food: In the wild, the chameleon is an omnivore. They sit on tree limbs waiting for their next meal to walk by. They will visually stalk or even climb after their prey. The eyes, which rotate independently 360 degrees, fixate forward on potential prey. When prey is spotted they coat their tongue with a sticky saliva, they open their mouth with their tongue protruding slightly. The end of the tongue is a bundled, accordion folded muscle surrounding a modified hyoid bone. When released the tongue, roughly the length of the chameleons body, shoots out, sticks to, and essentially grabs the prey. The tongue then retracts pulling the prey into the chameleons mouth. Chameleons eat a varied diet consisting of flies, crickets, grasshoppers, butterflies, roaches, arachnids, waxworms, stick insects, mealworms, etc. The largest species also can eat small mammals, small birds, and other lizards. In captivity, this meal pattern is impractical.
hope this helps answer you question
