What color is the Monarch chrysalis shell?

When we see a green Monarch chrysalis, we think of it as a green shell/cuticle. Actually, it’s a pale green. The bright green we see is the developing butterfly.

Maturing Monarch chrysalis/butterfly

As the butterfly matures, we see the color begin to form a day or two before it emerges.

We took a badly deformed chrysalis and euthanized it. We scraped the contents off the shell. This is what the shell looks like without a developing butterfly inside.

An empty Monarch chrysalis is pale green, not the rich green that we associate with Monarch chrysalises.
