Biological surfaces often exhibit complex structural features that influence their optical responses. In this study, we present synchrotron-based Small-Angle X-ray Scattering (SAXS) measurements of the exocuticles of Cetonia aurata and Calosoma sycophanta . The aim is to provide an initial characterization of their nanoscale scattering behavior and to explore possible structural features that may contribute to their appearance. Two-dimensional SAXS patterns obtained from the cuticles show heterogeneous and non-periodic scattering signals, indicating the presence of irregular nanoscale domains rather than well-defined periodic structures. To aid interpretation, these patterns were qualitatively compared with general scattering characteristics observed in disordered soft-matter systems. While the comparisons do not permit a definitive structural assignment, they offer a basis for discussing potential similarities in domain organization at the nanoscale. Overall, this study provides preliminary SAXS data on the cuticular structures of the examined beetle species and highlights the complexity of their scattering behavior. Further complementary analyses will be required to establish a more detailed and quantitative structural model.
