The telltale gold spots on the outside of a chrysalis are ports of entry for oxygen. Stringer has since expanded his spying into metamorphosis.
The crown of the Monarch pupa is called a diadem. If you look closely at the diadem, it’s a raised structure, a line of tiny hills. The combination of the raised hills and carotenoids present both absorb and reflects the light, creating the appearance of shiny gold.
Monarch caterpillars often turn black or darkish in color when they are sick with bacterial infections. This is often referred to as ‘black death. … OE is a protozoan parasite that infects monarchs. You won’t be able to tell if a monarch has OE until it’s in the pupal, or even adult, stage.
While pupa can refer to this naked stage in either a butterfly or moth, chrysalis is strictly used for the butterfly pupa. A cocoon is the silk casing that a moth caterpillar spins around it before it turns into a pupa. … This is the larva’s final molt as it transforms to a chrysalis.

Davis thinks the most likely explanation is that hand-raising caterpillars is too safe. In the wild, monarch caterpillars often become food for other animals. Only about five percent reach adulthood, Dr. … Davis thinks releasing these wimpier bugs en masse could harm the whole monarch population.
Predation. Invertebrate predators such as ants, spiders, and wasps attack monarch larvae on milkweed plants (Prysby 2004). … Birds such as black-backed orioles and black-headed grosbeaks are common predators at monarch overwintering sites. These species can eat large quantities of monarchs without getting poisoned.
No. Newly hatched adults do not eat the chrysalis. It is typically broken down by the weather.
