Unknown Stinging Slug Caterpillar

Dear Mike,
This is definitely a Stinging Slug Caterpillar in the family Limacodidae, but we are uncertain of the species.  The red color is quite unusual.  We believe it might be a Crowned Slug Caterpillar,
Isa textula, which is pictured on BugGuide, but we cannot locate any images of red individuals.  Sometimes caterpillars change colors right before metamorphosis.

Skiff Moth Caterpillar

Dear Ben,
You have the Slug Moth Caterpillar Limacodidae correct.  This is a Skiff Moth Caterpillar,
Prolimacodes badia, and here is a BugGuide image for comparison.  Your individual has much larger tubercles that those on most pictured specimens.  According to BugGuide:  “larvae feed on leaves of wide variety of trees and shrubs, including birch, blueberry, cherry, chestnut, Hophornbeam (Ostrya virginiana), oak, poplar, Sweetgale (Myrica gale), willow, and others” so we suppose “others” can include walnut.

Stinging Slug Caterpillar

Dear Subhash D,
This is a Stinging Slug Caterpillar in the family Limacodidae, and stings are reported to be quite painful.  We have not had any luck finding a close visual match to your caterpillar, but this image from Learn About Butterflies does illustrate the physical family traits generally associated with Stinging Slug Caterpillars.

Saddleback Caterpillar

Dear Sharon,
The Saddleback Caterpillar,
Acharia stimulea, is not considered rare, and BugGuide reports sightings in much of eastern North America.  The stinging capability of the Saddleback Caterpillar is well documented, including on Featured Creatures where it states:  “Color patterns are aposematic, or having bright warning colors that denote toxicity or distastefulness” and “The large spines and potent hemolytic venom rank it as one of the most important North American species of urticating caterpillars.”

Thanks so much for your quick response. We will definitely not be touching any more of them!

Your letter to the bugman:  These are about an inch long, and are aggressively moving through my garden. May be responsible for some painful skin reactions, but unconfirmed. Any idea what they are, and what they’ll turn into?

Stinging Slug Caterpillars

Dear Jon,
These are Stinging Slug Caterpillars in the family Limocodidae and we have previously identified them as
Latoia vivida.  Stinging Slug Caterpillars should be handled with extreme caution as they are capable of delivering a painful sting.

Wow, that was fast. Thank you so much!

Your letter to the bugman:  Hey bug man this little guy fell out of a tree in my windshield on my way home today  I’m semi new to Florida and know there are lots of crazy bugs here. Never seen one of these tho. It is about an inch long dark purple with some reddish orange on the underbelly. Did a reverse image search to try to find the species. No luck. Made it all the way home and took him off the car and realeased him in the grass. Thanks for any help!

Monkey Slug

Dear Jordon,
You should be commended on even recognizing that the Monkey Slug is a caterpillar.  Handle with caution.  Monkey Slugs can sting.
