This worm or caterpillar may be a silkworm. See Wikipedia for images of wild silk worms, which are green and segmented. Silk production was significant in early Mexico, and can still be found as a cottage industry in the Mixteca, state of Oaxaca. Here's a link to an image of a silkworm that shows a face and legs of a sort.
