Beautiful! I had one like this a few years ago. Took me a while to figure out what is was :)

Here is the butterfly that emerged from that pink chrysalis.

Notice how golden yellow it is.

Here is a Cloudless Sulphur where the caterpillar did not eat the yellow flowers of the Bahama Senna, it only had the new green leaves to eat. Notice how all stages are more green with the butterfly being more chartreuse than golden yellow.

I guess this supports "you are what you eat". :)

Everybody thinks that the ingested color chemicals are what color the caterpillars. Could be so. I offer the alternative thought that instead it could be the caterpillars' camouflage process.

Beautiful, javiwa!!! As Four says, the chrysalis color could be just part of the camouflage process. But why are the flies different colors? Another amazing butterfly mystery to ponder. :)
