Sphinx caterpillar

Honduras is in Central America not North America.

Your photo is of a hornworm in the family Sphingiidae.
However, it is NOT a Tetrio caterpillar. The Tetrio caterpillar has an orange band right behind the reddish head. It has reddish-orange prolegs as well as the rear claspers. Also, The tetrio larva of this hawkmoth has a long thread-like anal horn...which this does not. Here are photos of the Tetrio caterpillar for comparison - http://bugguide.net/node/view/570/bgimage

Since we do not have keys and ID info for insects in Central America, I am not sure which sphinx moth caterpillar this is.

Saw one in St. Lucia

Found one of these at a shopping mall where the cruise ships dock. Thanks for the picture. I wasn't sure what it was except big and colorful.

Your photo is of the Tetrio Caterpillar.
This larva is in the Sphingidae family of moths. Caterpillars of this family are ID'ed by the tail on the end of the caterpillar.
This larva feeds on plants in the dogbane family and can defoliate frangipani trees. When the larva are mature they pupate in the soil. Adult moths feed on nectar.
Here are photos of the adult moths, pupa and caterpillars.
