Your letter to the bugman: Hola from Chile! Here is a lovely fellow we found in our Valdivian rainforest climbing a laurel tree. He is probably around 2 inches long. I’m thinking he is in the Io moth family but he has no racing stripes. Identifying insects in Chile is difficult as there is little information available on line. Many thanks for your help!

Dear Chile Expat Family,
This is indeed a Giant Silkmoth Caterpillar and it does resemble the caterpillar of an Io Moth, and you are likely correct that it is in the same genus Automeris. It does look remarkably similar to another Chilean caterpillar that Bill Oehlke identified as likely a member of the genus Ormiscodes.
