Hello Bugman. I was gardening and was bit by the centipede (?) viewed in the attached photo. It was on the underside of a Manhattan Euonymus and attached to the leaf by what appears to be a bright green vest. This happened in East Setauket, New York (located in Suffolk County on Long Island).
I had extreme pain and a burning sensation that traveled up my arm for about six inches.
Can you identify what this is? Thank you for any guidance you can offer.

Dear Krista,
You were not bitten, but rather stung by this Saddleback Caterpillar,
Acharia stimulea, a species found in much of eastern North America.  According to BugGuide:  “Caterpillars are capable of inflicting lasting and painful stings with their spines.”

I found this today on my compost lid. The bug looks like it is wearing a lime green coat with a white fringe. It also looks like it has large lime green eyes and a red nose unless I am looking at the back end of that bug.

Hi Bugman! I love your site! I used you years ago and remembered you today when my daughter found this caterpillar. I was pleasantly suprised that you are still online. Thank you! She found this in Chapel Hill, North Carolina when weeding her garden. She only noticed it because it jagged or stung her arm. Not sure what it was feeding on. Thank you for your time.

Dear Marsha,
The stinging capabilities of the Saddleback Caterpillar,
Acharia stimulea, are well documented online including on Featured Creatures where it states:  “The saddleback caterpillar is encountered most frequently as a medically significant pest, and has minor effects in landscaping and agriculture.”

We saw this bug today, August 21, in Downingtown Pennsylvania. It was creeping along a leaf like it had lots of tiny centipede-like legs on the underside.

Hi Amanda,
Believe it or not, this is actually a caterpillar commonly called a Monkey Slug.  Handle with caution, or not at all, as the Monkey Slug can sting.

Can someone ID this caterpillar found this week in northern Baltimore County, MD, USA? It was found on a winterberry holly bush (Ilex species). I suspect that it’s a stinging slug caterpillar of some kind, but I can’t find a species that that matches the coloration.

Dear K Smith,
The coloration of the Spiny Oak Slug Caterpillar,
Euclea delphinii, appears to have considerable variation.  This image from BugGuide is quite close to your individual.

Hi, just curious about what this little guy might be – and I do mean little – I could barely see him with the naked eye. It is maybe 3mm long, and was found on a gum leaf, with what MIGHT have been eggs embedded in the leaf. Or not. Thanks :-)

Painted Cup Moth Caterpillar

Painted Cup Moth Caterpillar

Dear Ann,
This is a Painted Cup Moth Caterpillar,
Doratiphora oxleyi, one of the Slug Caterpillars in the family Limacodidae.  Many members of this family have stinging spines and there is a really nice image on FlickR.  You can read more about the Painted Cup Moth Caterpillar on the Butterfly House website where it states:  “Each shield bears four tubercles. Yellow stinging hairs are protruded from these when the Caterpillar is disturbed. These fold into triangular pockets when the Caterpillar is relaxed.  Along the sides of the caterpillar are fleshy spikes, like a skirt. There is also a flap covering the head. The spikes are translucent, and can be reddish or yellowish. The front pair are especially likely to be red. The caterpillars move like slugs because their legs are reduced.  The caterpillars feed on a variety of: Gum Trees.”  Though we have no shortage of family members on our site, your image is a new species for our archives.

Thanks very much for your reply Daniel. I’m pleased to have been able to send
you a new family member for your files. I will look out for a Painted Moth in
the Spring and see if I can add further to your database.

:-) Ann
