Caterpillar Automeris

muy buena foto!

Awesome!

I think that these white spots would be quite important. If they are missing and not just fainted it might be another species. But I am not sure.

It's like a moving forest. haha.

Nice spotting!

At first sight I fully agree with Metzli. Than I noticed the missing white spots in your shot and I am confused about Metzli. I am wondering what other people would say to this beautiful caterpillar.

Wowza... this caterpillar's venomous spines clearly mean business! I am confident this caterpillar is in the subfamily Hemileucinae, genus Automeris, which is full of stinging caterpillars. The body coloration and spines, along with your location, make me pretty sure this is A. metzli, but moth caterpillars especially are notoriously variable, so if anyone else has a better ID, I'm all ears!
