I have had maybe 3 mosquito bites in my life, despite having lived large stretches in the tropics. Mostly they don't even land on me, but I have watched when they do - the closest they get to biting is lowering their proboscis until it touches skin. Then they fly off. I always assumed it had to do with skin odour, probably diet related. It's surprising that the science isn't more advanced on this considering how harmful/annoying mosquitos can be and how primitive the current countermeasures are.
