Dung beetles guided by the stars

Views of the Milky Way provide more than just ambiance for the fecal-foraging insect.

Celestial navigation has guided man around the world for several thousand years. A new study suggests it could also be guiding dung beetles.

Marie Dacke, a zoologist at Sweden's Lund University, studies the way animals navigate. In a study online this week in Current Biology, she and a team of researchers looked into the surprisingly sophisticated navigational habits of the dung beetle, finding that they too have their eyes on the skies.

Here's how it works: Dung beetles like to maintain straight lines as they run. As they're going about their beetle business, when a pile of droppings catches their eye, they roll it into a ball and, walking backward, push it somewhere safe to eat. A straight course ensures they don't return to the fierce competition back at the dung pile.

Hmmm this lemon struesel cake I'm eating doesn't seem to taste as good now. Hahaaa

So interesting how they push it in a straight line and when it's overcast they lose their way. And why they roll on top of it. I wonder if they are smoothing out a little. Yuck.
