South African and Swedish scientists have discovered that dung beetles navigate using the Milky Way!

Dung beetles, as their name suggests, deal with feces. They converge on dung piles and roll away balls of it. While their existence may seem lowly, they're actually star gazers. More specifically, dung beetles use the Milky Way to navigate.They are the only animals who have been proven to use the stars for orientation.

The beetles have poor eyesight so they aren't looking at individual stars, but they do use the gradient of light to dark that the Milky Way offers to make sure they are rolling their dung balls in a straight line. That way, they don't accidentally circle back to the dung pile where they may have to fight off other beetles.

In experiments, scientists found that the beetles don't use individual stars or constellations to navigate. Rather, they use the band of light that is the Milky Way. They may seem gross, but it turns out that dung beetles are pretty resourceful.
