I came across a great number of these Caterpillars crossing an asphalt road near the Chuburna Marina. They all were traveling north to south, coming from a sandy beach area and headed into a swamp/marshy area. Who are these guys.

Possibly Periphoba aracaei Caterpillar

Dear YTM,
We believe this is a Giant Silkworm Caterpillar in the genus Automeris, and there are many species in Mexico.  We browsed the World’s Largest Saturniidae site and we believe this might be Automeris zozine, and we have contacted Bill Oehlke for his opinion.  Caterpillars in the genus Automeris should be handled with caution as they have stinging spines.

Giant Silkworm Caterpillar: Periphoba aracaei perhaps

Thanks, so much.  Love your site.  YTM
