Lime Butterfly caterpillar

Description:

Green with a tiara on the face...black bands on the sides. This one may be either final instar or almost there. Just resting quietly. Second shot has been cropped.

Habitat:

On a Curry patta plant or Murraya koenigii in my yard. I recently saw another one pupate (it is still inside its pupa) and that is why I had been on the lookout for more.

Notes:

I am always confused between the caterpillars of Common Mormon and Lime butterfly.
