The polydamas swallowtail chrysalis, I think, is very unique. The color often times depends on where they create it, as they can either be green, or brown.

The first one is well hidden in my Bahama cassia tree, resembling the color of a leaf. The last few photos are residing  in my butterfly house and are brown, similar to the color of the branch.

It will be interesting to see how long before the butterflies emerge. The last batch overwintered, which was fascinating because I live in Southwest Florida where the temps usually do not turn too extreme.
