The discovery of extraordinarily well-preserved, 47-million-year-old moths in Germany is revolutionizing our understanding of the evolution of insect iridescent colors. Unlike previously found fossilized insects, which usually show degraded colors due to chemical changes over time, these specimens retain their vibrant, iridescent colors, challenging long-held assumptions about the fragility and changeability of these colors. The findings not only provide direct evidence of the stability of iridescent colors but also suggest that structural coloration, a phenomenon where color is produced by physical structures rather than pigments, has a much longer evolutionary history than previously thought.
