Researchers from The University of Tsukuba used microscopy techniques to get an in-depth look at the exoskeleton of the ground beetle. Polarizing optical microscopy showed Maltese cross patterns that indicated a cholesteric liquid crystal-like helical structure in the inner layer of the wing casing. Scanning electron microscopy revealed regular hexagonal and needle structures on the outer and inner wing casing surfaces, respectively. These findings are expected to contribute to the development of useful biomimetic materials.
