Recently I found a Common Crow (Euploea core) caterpillar.

I decided to track the progress of the amazing chrysalis they make. A beautiful, golden metallic colour, that looks more like a piece of jewelry than anything else.

Progess above from Day 1 to about Day 9.
And finally, a beautiful Common Crow butterfly emerges.

Beautiful! I did not know of this species. Thanks for sharing.
Hey, Mark! One of the few species I see regularly here. 🙂
Wow! What an amazing chrysalis.
