"Luckily, this program, which is sponsored by the Air Force, really enables us to form these multidisciplinary teams that helped connect the dots to lead to this significant discovery. The diabolical ironclad beetle has a shell so tough it can be survive being run over by a car. The diabolical ironclad beetle, a desert bug native to California, can withstand nearly 40,000 times its body weight. When scientists looked at how the ironclad's two elytra are sutured together, they found the shields fit together like a jigsaw puzzle. In … ... co-author of the study from the University of California, Irvine. In collaboration with a group led by Atsushi Arakaki and his graduate student Satoshi Murata, both from the Tokyo University of Agriculture and Technology, they examined the chemical composition of the exoskeleton of a lighter flying beetle and compared it to that of their earthbound subject. The team also investigated the geometry of the medial suture joining the two parts of the elytra together and found that it looks very much like interlocking pieces of a jigsaw puzzle. “The ironclad is a terrestrial beetle, so it’s not lightweight and fast but built more like a little tank,” said principle investigator and corresponding author David Kisailus, UCI professor of materials science & engineering. Common Name: “Ironclad” beetle Scientific Name: Zopherus nodulosus haldemani Horn Order: Coleoptera Description: The striking adult beetle is 5/8 to 1 3/16 inch long and the body is adorned by a black and creamy white blotchy color pattern. Media access: Radio programs/stations may, for a fee, use an on-campus ISDN line to interview UCI faculty and experts, subject to availability and university approval. Its exoskeleton (integument) is extremely hard. Imaging scans showed the beetle's exoskeleton yields much of its strength from the elytra. Instead, it delaminates, providing for a more graceful failure of the structure.". A stink beetle or a Namibian beetle are more rounded. In its desert habitat in the U.S. Southwest, the beetle can be found under rocks and in trees, squeezed between the bark and the trunk – another reason it needs to have a durable exterior. They joined their biomimetic composite to an aluminum coupling and conducted mechanical testing to determine if there were any advantages versus standard aerospace fasteners in binding dissimilar materials. Researchers used a 3D printer to create a similar structural arrangement with synthetic materials. Instead, it delaminates, providing for a more graceful failure of the structure.”. The beetle is native to desert habitats in Southern California. What makes the diabolical ironclad beetle (the insect's actual common name) so indestructible? Summary 3. To further substantiate their experimental observations, Rivera and co-authors Maryam Hosseini and David Restrepo – both from Pablo Zavattieri’s lab at Purdue University – employed 3D printing techniques to create their own structures of the same design. The diabolical ironclad beetle is so tough, it can survive getting run over by a car applying ~100 newtons of force. "That's its adaptation: It can't fly away, so it just stays put and lets its specially designed armor take the abuse until the predator gives up," said Kisailus, a professor of materials science and engineering at the University of California, Irvine. Ironclad Beetles Zopheridae 1. Lead author Jesus Rivera, a graduate student in Kisailus’ lab during the project who has since earned his Ph.D., first learned of these organisms in 2015 during a visit to the renowned entomology museum at UC Riverside, where he and Kisailus were working at the time. Led by Chancellor Howard Gillman, UCI has more than 36,000 students and offers 222 degree programs. The study, led by engineers at the University of California, Irvine (UCI) and Purdue University, found that the diabolical ironclad beetle’s super-toughness lies in its two armorlike “elytron” that meet at a line, called a suture, running the length of the abdomen. Other species of the genus Zopherus, which contains 19 species, are known from western Texas. The diabolical ironclad beetle is, as its name suggests, one tough insect.Clad in super-tough body armour, the beetle can survive the heaviest of forces - as much as being run over by a car.

The diabolical ironclad beetle can survive loads of about 39,000 times its body weight. Among flying beetles, the elytra operate as forewing blades, a kind of sheath for a beetle's wings. "But we don't see that sort of catastrophic split with this species of beetle. The beetle’s survival depends on two key factors: its ability to convincingly play dead and an exoskeleton that’s one of the toughest, most crush-resistant structures known to exist in the biological world. In aerial beetles, elytra are the forewing blades that open and close to safeguard the flight wings from bacteria, desiccation and other sources of harm. The beetle's elytra are composed of layers of a fibrous material called chitin and supported by a protein matrix. He’s a materials scientist at the University of California, Irvine. UCI’s third annual Anti-Cancer Challenge sets fundraising record, UCI Center on Stress & Health awarded $6.3 million by National Institutes of Health, Native to desert habitats in Southern California, the diabolical ironclad beetle has an exoskeleton that’s one of the toughest, most crush-resistant structures known to exist in the animal kingdom. A cross section of the medial suture, where two halves of the diabolical ironclad beetle’s elytra meet, shows the puzzle piece configuration that’s among the keys to the insect’s incredible durability. Aulonium longum Bitoma gracilis Bitoma ornata Bitoma sulcata Coxelus serratus Hyporhagus gilensis Lasconotus laqueatus Lasconotus linearis Lasconotus nucleatus Lasconotus pertenuis The Purdue team’s models showed that not only does the geometry enable a stronger interlock, but the lamination provides a more reliable interface. "When you break a puzzle piece, you expect it to separate at the neck, the thinnest part," Kisailus said. The diabolical ironclad beetle dwells in desert regions of western North America. Closer examination revealed the presence of rodlike elements called microtrichia that researchers estimate work like friction pads, preventing layers from slipping when they experience delamination. Run over it with a car, and the critter lives on. They ran tests revealing that the arrangement provides the maximum amount of strength and durability. Tests showed the beetle's structural genius -- and the 3D-printed material it inspired -- outperforms the traditional rivets and fasteners used for aircraft segments and reinforce stress points. The diabolical ironclad beetle, a Southern California native, can withstand being crushed by forces almost 40,000 times its body weight. Birds, lizards and rodents frequently try to make a meal of it but seldom succeed. They can do that, researchers discovered, thanks to hardened casings … That means it can be run over by a car — and live to tell the tale. A 200-pound man would have to endure the crushing weight of 7.8 million pounds to equal this feat. In a study published in Nature, a British scientific journal, researchers explain this particular species of beetle is so squash-resistant because the insect's armor is layered and pieced together like a jigsaw. "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’s elytra have evolved to become a solid, protective shield. Jesus Rivera / UCI.
