A genus of small butterflies with golden or copper-colored wings, commonly called coppers, that are found worldwide.
From Greek 'chrysos' (gold) and 'phanos' (shining). The genus was named for the brilliant, metallic golden or coppery appearance of these butterflies' wings.
Copper butterflies (Chrysophanus) have wings that gleam like polished metal because of tiny ridges in their scales that scatter light—it's the same physics that makes oil slicks rainbow-colored!
