Help to ID caterpillars on plantsnap

Hello guys. Here it comes my first post. And it's about a cup of caterpillars I spotted while trying to ID a plant in the app plantsnap. The plant species is plumeria rubra. And this is the main image you can find if you try to identify the plant in this application

May you help me identify the caterpillars that appear on it?

Thank you.

Thank you very much, Frank. I was expecting a more spectacular moth as the caterpillars are though ?

Best regards.
