Nolid Moth Caterpillar

Description:

This caterpillar was about 1.5 inches long. It is about as wide as a pinky finger. It had a bulbous, green head, and crawled relatively fast. It has orange skin, but its underbelly is white.

Habitat:

I found this in the Singapore American School rainforest, located in Singapore. Singapore has a very humid and tropical climate, if that helps with the species identification.
