This is an early instar Hornworm from the family Sphingidae, and it looks to us like it might be in the genus Eumorpha, a group that has many members that shed the caudal horn in later, more mature instars, leaving a caudal bump instead of a horn. We could not locate any images on Sphingidae of the Americas that looks similar, but often very young, recently hatched instars are not well represented in images. This BugGuide image of a Gaudy Sphinx Caterpillar, second instar, is the closest visual match we could locate.
Awesome! That at least gives us a direction to go off of!
