Subject: Purple caterpillar with pink stripe

Hi, my mum recently spotted this purple caterpillar with a pink and white strip along its body. It has a long stinger on its rear end. It looks similar to the frangipani caterpillar that we also have here. We live in Trinidad and Tobago in the Caribbean. Can you help us identify it?
This is a Hornworm Caterpillar in the family Sphingidae, the family that includes the Frangipani Caterpillar, the larva of the Tetrio Sphinx. We searched the Sphingidae of Trinidad page to no avail. The horn reminds us of the caudal horn of early instar caterpillars in the genus Eumorpha, and we also wonder if this might be a strange color variation of the Tetrio Sphinx. We have contacted Bill Oehlke and we hope to hear back soon. We hope you will allow Bill to post your image to his very comprehensive site.
Thank you so very much for your help! Sure he can post the image, that’s no problem.
Bill Oehlke Agrees
Yes, I agree it is one of the Isognathus, and scyron is likely.
