Printable Butterfly Pdf Coloring Pages 09
Butterfly adults are characterized by their four scale-covered wings, which give the Lepidoptera their name. These scales give butterfly wings their colour: they are pigmented with melanins that give them blacks and browns, as well as uric acid derivatives and flavones that give them yellows, but many of the blues, greens, reds and iridescent colours are created by structural coloration produced by the micro-structures of the scales and hairs.
