We have just discovered that insects can navigate using the stars. So, to me, that reinforces that the stars can impact our actions - not just people, not just events like the tides but also in the movement of insects.
Scientists have shown how the insects will use the Milky Way to orientate themselves as they roll their balls of muck along the ground. Humans, birds and seals are all known to navigate by the stars. But this could be the first example of an insect doing so. The study by Marie Dacke is reported in the journal Current Biology.
Here is more of that article:
Dung beetles like to run in straight lines. When they find a pile of droppings, they shape a small ball and start pushing it away to a safe distance where they can eat it, usually underground. Getting a good bearing is important because unless the insect rolls a direct course, it risks turning back towards the dung pile where another beetle will almost certainly try to steal its prized ball.
Dr Dacke had previously shown that dung beetles were able to keep a straight line by taking cues from the Sun, the Moon, and even the pattern of polarised light formed around these light sources. But it was the animals' capacity to maintain course even on clear Moonless nights that intrigued the researcher. So the native South African took the insects (Scarabaeus satyrus) into the Johannesburg planetarium where she could control the type of star fields a beetle might see overhead.
Importantly, she put the beetles in a container with blackened walls to be sure the animals were not using information from landmarks on the horizon, which in the wild might be trees, for example. The beetles performed best when confronted with a perfect starry sky projected on to the planetarium dome, but coped just as well when shown only the diffuse bar of light that is the plane of our Milky Way Galaxy. The question is how many other animals might use similar night-time navigation. It has been suggested some frogs and even spiders are using stars for orientation.
