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 Automeris zozine Caterpillar

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:  Automeris zozine perhaps

Giant Silkworm Caterpillar: Periphoba aracaei perhaps

Thanks, so much.  Love your site.  YTM

Hi Daniel,
I believe it is Periphoba aracaei.
Any contact info so I can use image?

    These have quite a sting to them. I stepped on one and also got stung through a denim shirt when somehow one got onto me. Coincidentally, I also live in Chuburná Puerto, and found this article while searching what had stung me today.

    We just got stung in progreso. Very painful but not deadly. Exact same creature as the photo. Check all clothes that have been left outside and avoid.
