The dung beetle is one of the only animals known to navigate by the Milky Way. They roll balls of dung in dead-straight lines using polarized sunlight by day and the galactic light gradient by night. Pound-for-pound the strongest insect ever measured — pulling 1,141 times their body weight.

Range
Africa, parts of Mediterranean, introduced Australia
Diet
Mammalian dung
Found in
Savanna, grassland, pastoral land
Field guide
Dung beetles in the genus Scarabaeus are the textbook 'rollers' of the dung-beetle world — they shape herbivore dung into round balls and roll them in dead-straight lines away from the dung pile to bury and breed in. The straight-line behavior is critical: any deviation increases the chance another beetle steals the ball. Researchers in South Africa demonstrated in 2013 that Scarabaeus satyrus orients by the bright band of the Milky Way at night — making it the first insect (and one of the very few animals) known to navigate by galactic light. By day, the same species uses the polarization pattern of sunlight as a celestial compass, an ability shared with bees and ants. Mechanical-strength tests on the dung beetle Onthophagus taurus measured pulling capacities of 1,141 times the beetle's body weight — equivalent to a human pulling six fully loaded buses. Dung beetles are also significant ecological actors: in many grassland and savanna ecosystems, they remove and bury enough dung to reshape nutrient cycles. The Australian government imported African dung beetles in the 1960s specifically to deal with cattle waste that native fauna couldn't process.

Australia imported African dung beetles in the 1960s — native fauna couldn't process European cattle dung, so the country flew in beetles that could.

Ancient Egyptians revered the dung beetle as Khepri, god of the rising sun — observing that the beetle 'rolls the sun across the sky' the way it rolls its ball.

Cultural file
Dung beetles were sacred to the ancient Egyptians, who saw the rolling of the dung ball as a symbol of the sun's daily journey. Khepri, the dung-beetle-headed god, was a major deity associated with creation, transformation, and dawn. Scarab amulets — carved stone or faience replicas of dung beetles — are among the most common artifacts of pharaonic Egypt.
