Researchers have known for a while that dung beetles use the sun, the moon or other light source to navigate. Once the beetle acquires a dung ball from the poop pile they want to get away with their “loot” asap to prevent the competition taking it away. And they use a light source to help ensure they navigate in a straight line to prevent circling back to the original poop source and run into the competition.
Researchers from Wits University placed the beetles in a planetarium and clearly observed behavior showing the beetle can use the milky way’s band of light as an alternate light source when all other good sources are not available.
