![]() Researchers then used electron microscopes and CT scans to examine the beetle's exoskeleton and figure out what made it so strong.Īs is often the case for flightless beetles, the species's elytra - a protective case that normally sheaths wings - had strengthened and toughened over time. Other local beetle species shattered under one-third as much pressure. The species, which can be found in Southern California's woodlands, withstood compression of about 39,000 times its own weight.įor a 200-pound man, that would be like surviving a 7.8 million-pound crush. To understand what gives the inch-long beetle its strength, researchers first tested how much squishing it could take. And its design, they say, could help inspire more durable structures and vehicles. So, how does the seemingly indestructible insect do it? The species - aptly named diabolical ironclad beetle - owes its might to an unusual armor that is layered and pieced together like a jigsaw, according to the study by Zavattieri and his colleagues published in Nature on Wednesday. "This beetle is super tough," said Purdue University civil engineer Pablo Zavattieri, who was among a group of researchers that ran over the insect with a car as part of a new study. Now scientists are studying what the bug's crush-resistant shell could teach them about designing stronger planes and buildings. NEW YORK - It's a beetle that can withstand bird pecks, animal stomps and even being rolled over by a Toyota Camry.
