Multi-Layer Reflector in the Six-Spotted Tiger Beetle

The Six-Spotted Tiger Beetle (Cicindela sexguttata) is an iridescent species native to Pennsylvania, characterized by its striking coloration. In this study, we investigate the presence of a multi-layer reflector (MLR) in the beetle, which is hypothesized to contribute to its iridescence. Utilizing Scanning Electron Microscopy (SEM), we aim to identify the MLR within the elytra of the beetle. Based on previous studies of the Jewel Beetle (Chrysochroa fulgidissima), where the MLR has been well-documented, we hypothesize that the reflective structures may reside in the surface layers of the elytra. Preliminary findings suggest the presence of potential MLR regions, informed by the knowledge gained from the Jewel Beetle. Further analysis will focus on confirming the location and structure of these reflective layers in the Six-Spotted Tiger Beetle.
