Slug Caterpillar

Dear Landon,
We do not know how to calculate your location, but we are guessing Brazil.  Please confirm.  This is a Slug Moth Caterpillar in the family Limacodidae, and it looks very similar to a North American species, the Monkey Slug, and we suspect it might be in the same genus Phobetron.

Thank you!
Yes I live in Brazil.

Stinging Slug Caterpillar

Dear Asyraf,
This is a Stinging Slug Caterpillar in the family Limacodidae, but it appears different from this Malaysian Stinging Slug Caterpillar from our archives or this Blue Striped Nettle Grub, also from Malaysia.  While we can provide a family name, we are unable to provide you with a species at this time.

I was pruning our shrubs today and this thing got on the back of my fingers and stung/bit me. It really hurts! Took some Benadryl but am curious as to what this thing is and if I will live until morning! lol!

Saddleback Caterpillar

Dear Not a Bug Fan,
You were stung by a Saddleback Caterpillar, Acharia stimulea, and you will live.  Read How to Treat a Caterpillar Sting on WikiHow.  We have never received a photo of the underside of a Saddleback Caterpillar before, Your example is a good illustration of the rationale for calling the family that the Saddleback Caterpillars belongs to, Limacodidae, the Slug Caterpillar Moth family.

Greetings – Have just happened onto your page in process of trying to identify what turned out to be a Hag Moth larvae which dropped onto my hand today. Will doubtless be back – very useful sight – especially for nat’l science junkies.
I will attach a screen shot of the top left area of your home page which is somehow missing some of the text to tell us what we need to click on to reach the ’Ask WTB’ and ’Bug Love’ linked pages. (Have worked on websites – not a techie, but writer/editor and pay attention to such stuff.) Thought I’d share the info in case you hadn’t seen it. Thanks…

Monkey Slug

Hi Sue,
We are happy you were able to identify your Hag Moth Caterpillar, commonly called a Monkey Slug, thanks to our website.  As a side note, we accidentally hit the “t” instead of the “g” when naming the Monkey Slug and we needed to correct that error prior to posting since we try our best to maintain a G rated website.  Thanks for bringing the homepage problem to our attention.  We will copy our crack webmaster on this matter to see if he can get to the root of the matter.  We just checked it out on our Safari and Firefox browsers and it is fine.

WTB? Screenshot with technical problem

My son spotted a very odd looking insect crawling up a tree at our home in Vermont. It was orange in color and looked like the inside of a crab shell on the back but moved very much like a snail. It had a wormlike head and measured approximately one inch long and was soft and had no shell. What is this thing?

Monkey Slug

Hi Steven and Conner,
This creature, which is commonly called a Monkey Slug, is the caterpillar of the Hag Moth.  Handle with caution as they are capable of stinging.

Monkey Slug

Hi Dylan,
You were astute to recognize this Monkey Slug as a caterpillar.  It is actually the caterpillar of the Hag Moth, Phobetron pithecium.  The Monkey Slug is capable of stinging, so handle with caution.  We are amused that this Monkey Slug was photographed in the city of Monkton.
