I offer termites every year. Most of my chameleons eat them fine, but some don't seem to prefer them. I mostly use pale coloured "workers" taken out of logs more than the flying "new queen" ones.
however, your photo appears to show ants, not termites?
at least the flying termites here look a bit different than your photo. Maybe a different type of termite than what I am used to. Im mostly more dampwood termites, rather than subterranean termites.
