Phloeodes diabolicus has one of the toughest natural exoskeletons scientists have ever seen. Battle. Meet the diabolical ironclad beetle (pretty boss name, if you ask us). The diabolical ironclad beetle (Phloeodes diabolicus) of North America doesn’t have the visual pizzazz of some of its more shiny beetle cousins, looking more like a small piece of gnarly bark or stone. The study shows just how amazing this jigsaw puzzle is when more force is applied to the beetle’s shell. save. Why is he fundraising for it? Drive over the beetle in your car and it won't even break a sweat. (15 kilograms). The diabolical ironclad beetle is found in the forests of North America's Pacific coast. What does the "ironclad" beetle eat? The diabolical ironclad beetle’s shell has a crazy jigsaw-like structure that makes it super tough. This could lead, for example, to safer aircraft engines, which employ fasteners that add structural stress that decrease the durability of the overall engine. In flying beetles, the elytra are the hard forewings that act as wing cases to protect the more delicate veined hindwings that the insect uses for flight. The species, which can be found in Southern California’s woodlands, withstood compression of about 39,000 times its own weight. They discovered that the "iron" beetles could resist continuous forces up to 149 newtons, or 33 lbs. So, how does the seemingly indestructible bug manage to survive against all odds? So tough is its exoskeleton, entomologists have found it challenging to mount the beetle for display using steel pins. Scientists are unraveling the mystery of a bug with one of the coolest names in the animal kingdom: the diabolical ironclad beetle. © 2020 CBS Interactive Inc. All Rights Reserved.

The diabolical ironclad beetle does not have wings, so its elytra and connective suture help to distribute an applied force more evenly throughout its body. This exoskeleton, the team found, is composed of chitin, a fibrous material derived from glucose, and a protein matrix. What the species you are keeping needs, can be found at the Species Description page. This combination of features allows the elytra to deform more gently, which dissipates energy more evenly and prevents the exoskeleton from snapping and killing the insect. When they compared the diabolical ironclad beetle’s exoskeleton to that of a similar beetle, they found that the ironclad had significantly more protein – about 10 percent more by weight. Yikes. Scientists say the armor of the seemingly indestructible beetle could offer clues for designing stronger planes and … Specifically, its elytra — the blades that open and close on the wings of aerial beetles — have fused together to act as a solid shield for the beetle, which can't fly. Instead, it delaminates, providing for a more graceful failure of the structure.”. But the suture line along which the beetle’s elytra are fused ended up playing a crucial role in its toughness. Rather than snap apart, as you’d expect puzzle pieces to do, the microstructures within the exoskeletal blades gave way to layered parallel fracturing, a process known as delamination. "This study really bridges the fields of biology, physics, mechanics and materials science toward engineering applications, which you don't typically see in research," Kisailus said. "The ironclad is a terrestrial beetle, so it's not lightweight and fast but built more like a little tank," lead author David Kisailus, a UCI professor of materials science and engineering, said in a news release. Just imagine the weight of having 39,000 clones piled on top of you. Analysis of the elytra revealed that it's made of layers of chitin, a fibrous material, and a protein matrix.

A diabolical ironclad beetle can withstand being crushed by forces almost 40,000 times its body weight and are native to desert habitats in Southern California. Flying is a great defense mechanism for beetles, allowing them to escape predators, but the battleship has no wings and often plays dead, relying on its exoskeleton to keep it safe. With 400.000 species of beetles on the earth there are almost as many different ways to keep them. “It connects various exoskeletal blades – puzzle pieces – in the abdomen under the elytra.”. Zopherus nodulosus haldemani, what can I feed this thing to keep it alive? Now scientists might have finally figured out its secrets – and are starting to apply them to new materials. The similar beetles were able to withstand an average peak load of less than 68 Newtons. It's only about two centimeters long, but built like a tiny top-0f-the-line military tank—capable of surviving being run over by your car, according to an Oct. 2020 study published in the journal Nature.Yes, this is an actual scientific fact—and one that could lead to groundbreaking engineering innovations. Researchers from Japan, Indiana, and California recently measured how much force the shell could withstand without breaking and measured a maximum force of 149 Newtons (N), and an average force of 133 N. Other species of the genus Zopherus—there are 19 other known species belonging to this group—are typically found in western Texas. “That’s its adaptation: It can’t fly away, so it just stays put and lets its specially designed armour take the abuse until the predator gives up.”. Under compression, the jigsaw puzzle-like structure of the elytra doesn't snap as expected, but rather, fractures slowly. This 2016 photo provided by the University of California, Irvine, shows a diabolical ironclad beetle, which can withstand being crushed by forces almost 40,000 times its body weight and are native to desert habitats in Southern California. More Ironclad Beetle Facts And Questions. Because the diabolical ironclad beetle doesn’t fly, its elytra have hardened even further and become locked together along a suture line to act more like armour. The beetle can withstand a force of about 39,000 times its body weight — the equivalent of a 200-pound man enduring the weight of 7.8 million pounds. hide. First, they conducted steel plate compression tests of the entire exoskeleton to ascertain just how much force the beetle could withstand, comparing the results to other beetle species from the same region with similar predators, such as pecking birds, and the same defence strategy, playing dead. They also conducted simulations and used 3D printed models to verify their findings. share. But what it lacks in dazzle, it makes up for in durability: its exoskeleton is one of the toughest materials in the natural world. The team collected their beetles from the Inland Empire region of California. Unlike most beetles, the diabolical ironclad beetle cannot fly; its wingcases are fused together to form a protective armor. Just imagine the weight of having 39,000 clones piled on top of you. Scientists believe that understanding just what makes the iron beetle so tough will have practical applications for humans, too. “The suture kind of acts like a jigsaw puzzle. “The ironclad is a terrestrial beetle, so it’s not lightweight and fast but built more like a little tank,” said materials scientist David Kisailus of the University of California Irvine. A team from Purdue University and the University of California, Irvine (UCI) have deduced that when an extreme amount of pressure is put on the beetle, its "crush-resistant" shell adapts to the situation by stretching, rather than shattering. Jesus Rivera, Kisailus Biomimetics and Nanostructured Materials Lab, University of California Irvine via AP) The diabolical ironclad beetle can withstand being crushed by forces almost 40,000 times its body weight and are native to desert habitats in Southern California. “The suture kind of acts like a jigsaw puzzle,” said materials scientist Pablo Zavattieri of Purdue University. The Guardian | 10-21. The architecture and material composition of the entire exoskeleton accounts for some of the toughness; but the key, the researchers found, lay in the elytra. Using compressive steel plates, UCI researchers found that the diabolical ironclad beetle can take on an applied force of about 150 newtons—a load of at least 39,000 times its body weight—before the exoskeleton begins to fracture. For engineers pursuing advanced, ultra-tough materials, it can pay to look to the natural world for inspiration, and the diabolical ironclad beetle is not a bad place to start. According to research published Wednesday in the journal Nature, the insect's armor is so durable, few predators have successfully made a meal out of it — and it can even survive getting run over by a car.
