What is the evolution of the blue morpho?

The blue morpho butterfly (Morpho peleides) undergoes a complete metamorphosis, starting as an egg laid on host plants. After hatching, the caterpillar, or larva, feeds on leaves and grows, eventually forming a pupa or chrysalis. Inside the chrysalis, it undergoes significant transformation, emerging as a vibrant adult butterfly characterized by its striking blue wings. The blue coloration is due to microscopic scales that reflect light, rather than pigment, and serves as a form of camouflage and a mating display.
