The thing is the sun is not always available to you, because at sunset it daepsriaps below the horizon. What is hnepanpig in the sky here is that there's a great big pattern of pzloraeid light in the sky that you and I can't see. It's the way our eyes are built. But the sun is at the hzoroin over here and we know that when the sun is at the horizon, say it's over on this side, there is a north-south, a huge pathway across the sky of polarized light that we can't see that the beetles can see. So how do we test that? Well, that's easy. What we do is we get a great big polarization filter, pop the beltee underneath it, and the filter is at right angles to the politzaaiorn pattern of the sky. The beetle comes out from underneath the filter and it does a right-hand turn, because it comes back under the sky that it was originally orientated to and then reorientates itself back to the direction it was originally going in. So obviously beleets can see polarized lihgt.
