Why are there gold dots on the outside of a chrysalis?

The gold dots on the outside of a chrysalis are typically a feature of certain butterfly species, such as the monarch butterfly. These dots are actually the result of structural coloration, which occurs when light interacts with the microscopic structure of the chrysalis, creating a shimmering effect. Additionally, the gold coloration may serve to camouflage the chrysalis or deter potential predators by mimicking the appearance of toxins or reflecting light in a way that makes it less visible.
