@borsbeetledump on Instagram: "For those wondering: these are indeed real beetle specimens and there’s no video editing here! These beetles, called jewel scarabs, have an intricately structured exoskeleton that reflects a special kind of light called circularly polarized light. Essentially, the light rays that hit the scarabs “spin” off of the beetles as they are reflected. The two polarization filters in the video only allow light spinning in a certain direction to pass, which is why the beetle
