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!

Unknown Giant Silkmoth Caterpillar

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.

I guess that entomology course I took 30+ years ago came in handy!

Your letter to the bugman:  I’ve never seen a caterpillar this big in my life. Is it a danger to my clothing, garden, cats or dogs that may get hold of it? What kind is it?

Imperial Moth Caterpillar

Dear Stephanie,
The midwest is a big place.  More location specificity is always desirable.  This is an Imperial Moth Caterpillar and it will not harm your clothing or your cats or dogs.  Imperial Moth caterpillars are not too particular about the leaves they feed upon and according to BugGuide:  “Larvae feed on leaves of Bald Cypress, basswood, birch, cedar, elm, hickory, Honeylocust, maple, oak, pine, Sassafras (
Sassafras albidum), Sweetgum (Liquidambar styraciflua), sycamore, walnut.”  They do not feed enough to cause a tree damage unless it is a very young tree.

Your letter to the bugman:  We found this Sept, 27 early evening in New River, AZ (2,000 ft elevation).  I have not found anything like it in my searches.  The shiny silver barbs on its back come out when agitated.

Cecrops Eyed Silkmoth Caterpillar

Dear Urbanohno,
What a marvelous find.  These are caterpillars of the Cecrops Eyed Silkmoth which we identified on BugGuide.  According to BugGuide:  “Adults in spring. Eggs are laid in rings on twigs of host plant. Early instar larvae are gregarious and feed in large groups, but they spread out and become solitary in later instars. Larvae are present in summer to early autumn. Overwinter as pupae in cocoons woven among (or incorporating) vegetation, mostly leaf litter on ground, sometimes on plants.”

Ah so – Thank You very much Daniel!

Prepupal Imperial Moth Caterpillar

To Whom it may Concern,
You are not the Bugman.  You have requested information from the Bugman.  This is a prepupal Imperial Moth Caterpillar which has finished feeding, left the tree upon which it was feeding, and it is now looking for a place to dig so it can pupate underground.  The adult Imperial Moth is a gorgeous creature.

Lol! I am certainly not the bugman! I thought that space was for how I wanted the letter to me signed; I was very concerned! Thanks for the information!
Crysta aka NOT the bugman

Thanks Crysta.
