The researchers addressed this second aspect by fitting their test-subject ladybugs with transparent acrylic elytra and observing the wing folding using high-speed photography. Complicating matters further is the fact that ladybird beetles close the elytra ahead of wing folding, preventing the observation of detailed folding processes.” In contrast, the other fundamental problem, namely the mechanism behind the folding of these wings, remains unclear. Investigation of other species of beetles indicated the existence of a hydraulic mechanism that straightens the wing veins. Saito and his colleagues at the University of Tokyo, the National Museum of Nature and Science, and Kyushu University note in the paper’s abstract, “Researchers have found that the intrinsic elasticity acting in wing veins allows this high-speed deployment. It’s described in “Investigation of Hindwing Folding in Ladybird Beetles by Artificial Elytron Transplantation and Microcomputed Tomography, by Kazuya Saito et al. Little was known about the ladybug’s quick transition from walking to flying until Japanese researchers applied methodology that, in its own way, is as fascinating as the ladybug’s wing deployment and retraction. Yet these primary wings are deployed in only a tenth of a second and retracted origami-like in just two-tenths. These hardened front wings are called elytra, and they provide protective covering for the ladybug’s magic: Its hind wings unfold to be four times the ladybug size.
