In 2015, Jesus Rivera filmed a very unusual science experiment for posterity. On the asphalt of a sun-soaked parking lot, he placed a mottled black beetle on a pillow of dirt and had a colleague run it over with a Toyota Camry. Twice. Just about any other bug would have died. This one, a species called Phloeodes diabolicus, did not. … “That would jellify a human,” said David Kisailus, an engineer at the University of California, Irvine, who mentored Dr. Rivera’s work. [Subscription required, campus-wide access provided by UCI Libraries.
