Subject: Hawaiian Hornworm?

Aloha! I saw this caterpillar while on a hike of western Oahu. The area was near the ocean and windy. I’m questioning if it might be related to the tomato/tobacco hornworm family.
You are correct that this is a Hornworm in the Sphingidae family. We looked through the Sphingidae of Hawaii where we thought the closest match was Agrius cingulata, the caterpillar of a Pink Spotted Hawkmoth. We checked that on BugGuide where we found an individual that looks very similar to your caterpillar. Agrius cingulata is a highly variable caterpillar and this is just one possible color variation.
