I have been doing some internet research and this is what I found.
These flying "ants" are actually flying termites known as termite swarmers or termite alates (meaning - having wings). They are the species known as Coptotermes formosanus or commonly Formosan Subterranean Termites. A termite swarmer cannot harm you as it is designed for propagation of the species, not to eat wood. The swarmer cannot bite or sting and they do not produce formic acid like ants. The worker termite (the one that resembles a small, white ant) is the one that has the strong, sharp jaws used for chewing wood.
Dispersal flights or "swarms" are massive and begin at dusk on calm and humid evenings from October to January. After swarming, landing, and shedding their wings, the adults pair off and move about in tandem, with the male following the female searching for a place to live. Fortunately, very few of these pairs survive to start new colonies. Most are soon eaten by geckos, spiders, chameleons, toads, ants, or other predators.
So, if these swarmers can't bite, sting or spray formic acid then they should be perfectly edible to a chameleon? My dogs eat them by the numbers and I know of people who have fried them and eaten them. Apparently they taste like butter so I assume that they have a high fat content and will not give too many to my cham.
