The scientists think the insects get on top of dung when it gets hot to give themselves a respite from scorching sands and help protect their brains from overheating. The researchers found the front legs of the beetles cooled by about 12 degrees F 7 degrees C on average within 10 seconds of climbing on their excrement balls.
Once on top of the balls, the insects were often seen "wiping their faces," preening gestures the investigators think spread regurgitated liquid onto their legs and heads, behavior never seen at other times of day. The scientists detailed their findings in the Oct. Follow LiveScience on Twitter livescience. IE 11 is not supported. In the Copris and Ontophagus dung beetles, the male and female work together to dig their nests.
Certain Cephalodesmius dung beetles even mate for life. For most dung beetles, not just any poop will do. Many dung beetles specialize on the dung of particular animals, or types of animals, and simply will not touch the poo of other critters. Australians learned this lesson the hard way when the outback was nearly buried in cattle dung. Two hundred years ago, settlers introduced horses, sheep, and cattle to Australia, all grazing animals that were new to the native dung beetles.
The Australian dung beetles were raised on poop from Down Under, like kangaroo poo, and refused to clean up after the exotic newcomers. Around , Australia imported exotic dung beetles that were adapted to eating cattle dung, and things got back to normal.
When it comes to poop, the fresher the better at least from the dung beetle's perspective. So dung beetles move quickly when an herbivore drops a gift in the pasture.
One scientist observed 4, dung beetles on a fresh pile of elephant scat within 15 minutes after it hit the ground, and shortly thereafter, they were joined by an additional 12, dung beetles. So the first thing the dung beetle does is climb atop his sphere and orient himself.
Scientists had long observed dung beetles dancing on their poo balls, and suspected they were looking for cues to help them navigate. New research confirmed that at least one species of African dung beetle, Scarabaeus satyrus , uses the Milky Way as a guide to steering its dung ball home. The researchers placed tiny hats on the dung beetles, effectively blocking their view of the heavens, and found the dung beetles could only wander aimlessly without being able to see the stars.
Have you ever walked barefoot across a sandy beach on a scorching hot summer day? If so, you probably did your share of hopping, skipping, and running to avoid painful burns to your feet.
Since dung beetles often live in similarly hot, sunny places, scientists wondered if they, too, worried about burning their tootsies. They then burry the ball to either munch on later or to use as a place to lay their eggs. The female beetle then stays in the tunnel sorting out the dung brought down by the male. Dwellers, on the other hand, simply live inside the pooey pile. Female dwellers lay their eggs there, and when the larvae or young hatch they happily munch away on the food that surrounds them.
Nom nom nom! So, why would a insect want to eat poo? Well, when an animal such as an elephant, cow or rhino munches on some tasty grub, there are always parts of the food that pass through its body undigested, and end up in its dung. Its these nutritious bits of undigested food that dung beetles tuck into. Larvae eat the solid poop, while the adult beetles generally suck up the nutritious moisture found inside the dung.
These cool critters may be small, but boy are they are they mighty! While you wait for it to be checked and approved why not to add a pre-selected message and a cool badge. Ask a parent or guardian to check it out first and remember to stay safe online. See all. There are about species worldwide, concentrated in the tropics where they feed mainly on the dung of terrestrial vertebrates. Dung beetles have been cleaning up the planet ever since; but what on earth do they do with all that poo?
Here are the top five most interesting. Vulgar and aggressive, but true. Dung beetles eat dung. All organisms need nitrogen to build proteins, such as muscle. Dung beetles get theirs from dung. By eating poo, dung beetles may be selecting the cells from the gut wall of the herbivore which made it.
These are a protein-rich nitrogen source.
