Coordinator notes: Coordinator 1: This is a sphingid larva, belonging to the genus Eumorpha. There are about a dozen species in this genus found in Mexico. This individual is rather similar to Eumorpha typhon, though I cannot be certain as I have not seen images of all Eumorpha species found in Mexico. -Ryan St. Laurent Coordinator 2: This looks just like many of the photos of Eumorpha typhon I found on the web, so I am certain the id is correct. Perhaps the black bands do not always appear unless the caterpillar is fully stretched like in the sighting photo, hence are not evident on photos on MPG and bugguide. However, the following web sites show photos of the caterpillar with the black bands, some are sharper and darker than others, so there evidently is some variability in this characteristic. The green form does not seem to show the black bands in any photo I could find.
