Found this caterpillar in our carport. Central jungles of Peru near Pucallpa. I’ve never seen one like this but something tells me I’d rather not touch it.

Giant Silkworm Caterpillar

Dear Jungle Jack,
This is one of the Giant Silkworm Caterpillars in the family Saturniidae, but we haven’t the time right now to try to identify the species.  We will post it as unidentified in the hopes that one of our readers might provide an answer.  You were wise not to handle it as many caterpillars in this family have stinging spines.

I am pretty sure it is a Pseudautomeris species in Hemileucinae subfamily of
Saturniidae, but I do not know which one.
I will look up Pucallpa to see if that helps narrow it down.

Update from Bill Oehlke
While doing some other work, I came across larva of Automeris innoxia, and
it seems a very good match for the Peruvian caterpillar.
