Scientists have figured out how ladybugs fold their wings by transplanting a transparent artificial wing onto the insect and observing its underlying folding mechanism. The study's findings, which help explain how the wings can maintain their strength and rigidity during flight, while becoming elastic for compact folding and storage on the ground, provide hints for the innovative design of a wide range of deployable structures, from satellite antennas to articles for daily use like umbrellas and fans.
