Most 'bees' don't like talking about 'ultraviolet', especially in a communal setting

This is true in my experience, and I would like to see it explained.

Why do they have special behaviors regarding the particular spectrum that autistics can't see? Are autistics so numerous or influential that non-autistics have developed behaviors to target them? Are the mechanisms behind autism related to special properties of this spectrum which wouldn't be present for other 'colors'? Does the signalling that Hanson's Homo Hypocritus theory say isn't discussed explicitly just happen, by coincidence, to be the same signaling that autistics are unable to perceive? (And if so, why hasn't selection reduced the numbers of autistics more?)
