Hello! I was trekking in Chiloe national park, in the great island of Chiloe, Chile, and I find this beautiful caterpillar, but no one could tell me it’s species. I hope you could tell me more about it. Cheers!

We believe your Giant Silkmoth Caterpillar is in the subfamily Hemileucinae, the Buck and Io Moths. Furthermore, we believe it is in the genus Automeris because of it strong resemblance to the North American Io Moth Caterpillar. The closest match we could find is the Caterpillar of Automeris hamata, a species pictured on DeviantArt and found in Argentina. We will contact Bill Oehlke to see if he can provide any information.

Larvae of Chilean Saturniidae are not well known. It is one of the Hemileucinae species, and I suspect of Ormiscodes genus based on spinage. There are probably six different Ormiscodes species from that area.
Here is a link to Healthy Home Garden that contains images of a caterpillar in the genus Ormiscodes.
