Dear Kary,
These Caterpillars are commonly called Monkey Slugs and they should be handled with caution as they are capable of delivering a painful sting.

Coworker found this on her truck, last summer…maybe end of July. We are in Columbus, Georgia, United States.
She said this bug was in the process of forming a web; it was leaving some sort of sticky substance. It ‘slid’ like a slug but moved sideways, it had no legs. It looks as if it has some sort of horns above what she thinks are the eyes. She saw a smaller one the next day but never saw anymore and hasn’t been able to find out what it is online or in any book she’s researched.

Dear Monica,
This is a Monkey Slug, one of the Stinging Slug Caterpillars in the family Limacodidae.  It appears to be missing several of its “arms” and it is described on BugGuide as being:  “Bizarre, brown, hairy creature that resembles some sort of aquatic creature more than a caterpillar. Three pairs of long arms and three pairs of short arms, which are “deciduous” – often one or more is missing.”  It is capable of stinging and it should be handled with caution.

I stood on this and am in considerable discomfort. I’m a bit worried that they are poisonous.

Stinging Slug Caterpillar

Stinging Slug Caterpillar

Dear James,
This is a Stinging Slug Caterpillar in the family Limacodidae, and it matches this image on iSpot that is only identified to the family level.  We have several images of this Stinging Slug Caterpillar in our archives and we believe it is
Latoia vivida.  According to this Taylor Francis Online article:  “Larvae of the moth Latoia vivida (family Limacodidae) have spiny tubercles which cause sharp pain and subsequent urticaria upon contact with human skin.  This study describes the sting’s clinical consequences and evaluates the effect of various pharmacological modifiers on the clinical response.”  We suggest that you refer to that article and consult a physician if your symptoms persist.

Dear Bugman.
Thanking you in advance for your time herein.
We went away to Rust De Winter the weekend of 2 Jan 2016 and took note of an interesting caterpillar.
We have tried doing research on this caterpillar, so that we can learn more about it, but we can`t seem to find much info of this caterpillar.
Would you be able to assist?
Regards, Vicky

Dear Vicky,
We wish you had been able to provide higher resolution files of your lovely images as they are quite degraded when enlarged.  These are Stinging Slug Caterpillars in the family Limacodidae.  We did locate a similar looking image on iSpot, but it is only identified to the family level.

Hi there,
I live in Southern Brazil and I found a very strange bug on a cherry tree, during the summer (about 90F), in the morning. I am very curious because I have never seen something like it. It moves slowly (well, at least after I kicked him) and it is very hairy. Here are some pictures.
Thank you!

This looks similar enough to a North American Monkey Slug that we believe your individual is also a member of the genus Phobetron.  When we previously posted a similar image from Brazil, we learned that a common local name is:  “‘Lagarta-Aranha’ something like ‘Spider Catterpillar’ in English.”

Hi ,
I am currently staying in Guatemala while i was trimming roses something fell on me. At first glance i thought it was a spore but once I felt pain and a slight burning sensation I realized I was wrong. I found so many of these critters varying in sizes and they are always in groups . I just want to know if they are safe for my grandfather’s garden.

Dear Crystal,
These are either Saddleback Caterpillars,
Acharia stimulea, which according to BugGuide ranges from “Massachusetts south to Florida and west to eastern Missouri and Texas,” or another member of the genus that ranges further South.  As you noted, they are capable of stinging, and according to BugGuide:  “Caterpillars are capable of inflicting lasting and painful stings with their spines,” however, the sting is not considered dangerous.  We suspect your grandfather is already aware of these Saddleback Caterpillars and their stinging potential.
