The gold spots on the Monarch chrysalis are a mystery that has inspired much curiosity. The gold color is produced not by a pigment, but by structural iridescence. In other words, the metallic luster you see results from the refraction of light from the multiple laminae (layers) of the cuticle of the pupa. The multiple colors seen when oil is spilled on water are produced in the same way. In an attempt to determine the function of these gold spots, Fred Urquhart conducted a series of controlled experiments in the early 1970s. He found that the destruction of these spots caused the wing scales to fade, or reduced the number of scales on the head or abdomen, depending on which spots were destroyed. From this he concluded that the gold spots are associated with scale formation and pigmentation; however, we still do not understand specifically how the gold spots influence these aspects of development. It is possible that the gold spots represent major sites of organization for wing tissue and/or epidermal cells.

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.

Where do monarch caterpillars make their crysalis?
Monarch caterpillars typically make their chrysalises on the undersides of leaves or in sheltered locations like stems, branches, or fences. They often choose spots that offer some protection from predators and harsh weather. After attaching themselves with a silk thread, they undergo transformation into a chrysalis, which is usually green with gold accents. This process usually takes about 10 days to two weeks before they emerge as adult butterflies.
