Stinging Slug Caterpilar

Dear Eric,
We were about to disagree with your identification until we learned on Wikipedia (not our favorite site to reference) that Euclidae is synonymous with Limacodidae, the family that contains Stinging Slug Caterpillars.  This does appear to be a Stinging Slug Caterpillar, but we have not been able to locate a matching image online that might lead to a species identification.  We have no medical credentials and we cannot dispense any medical advice, but we would encourage your acquaintance to seek medical treatment if symptoms persist.

My friend found this little critter in his yard here in southern New Jersey. It bit him and almost 2 hours later his arm is JUST now going back to normal. What is this?

Saddleback Caterpillar

Dear Erin,
We suspect the next time your friend encounters a Saddleback Caterpillar, your friend will look and not touch, since that is the best way to interact with Stinging Slug Caterpillars from the family Limacodidae.

Hi!
Found this little guy (ca 3cm) wandering the road near my house today and wondering what he is/what he’s going to be. Have found a lot of similar caterpillars online in the stinging slug variety, but none that match him perfectly.
Can you help identify him for me?

Stinging Slug Caterpillar

Dear Nina,
This is a Stinging Slug Caterpillar in the family Limacodidae, and as its name indicates, it is capable of stinging if it is carelessly handled.  We have found matching images on the internet with two different genus names.  This FlickR image is identified as
Latoia consocia, and JP Moths identifies it as Parasa consocia.

Hi!
I just wanted to say thank you for helping me identify this caterpillar so quickly!
Love your website!

What kind of bug is this? It was sitting on a fence rail and my wife brushed it with her arm. She said it immediately started to tingle and left her with a (very) small welt.

Dear Neal,
We believe we have correctly identified your Stinging Slug Caterpillar as
Natada nasoni thanks to this BugGuide image.  According to BugGuide:  “Larvae feed on beech, hickory, and hornbeams.”
