Strange Panamanian Catepillar

So I found this large caterpillar just outside of Panama City, Panama and have no idea what it is. I was hoping you could help me. It has a red head, jet black body with yellow-white stripes, and orange legs and rear with a black spine. It was almost 6 inches long too, definitely the longest caterpillar I have ever seen!

The caterpillar of the Tetrio Sphinx,
Pseudosphinx tetrio, is quite distinctive.  You can read about the Tetrio Sphinx on the Sphingidae of the Americas website.

    This caterpillar has been known to be in the country of the Commonwealth of Dominica, Lesser Antilles, where I live for many many years. Currently I have one observing.

    They are also in Mameyes, Dominican Republic. My son just saw on & sent me the picture because it was so big & brightly colored.
    I hope it’s not poisonous!?
