Dear Bugman
Is this a stinging slug caterpillar. My son was bitten on it, while cycling past a bush. It produced a stinging sensation and urticaria on his arm. We live in Kuala Lumpur, Malaysia

Stinging Slug Caterpillar

Dear Xav and Con,
We agree with your identification that this is a Stinging Slug Caterpillar in the family Limacodidae.  We located a matching photo on FlickR, but it is only identified to the family level.  Perhaps one of our readers will have better luck with a species identification.

Hi, this was crawling across the road, very very slowly, in a heavily wooded setting with a lot of hemlock trees, and mixed oak forest type, in Alstead, NH on October 6, 2013. The Black & White photo was altered to highlight the appendages. Those were not feet as far as we could tell. Thanks!

Hello bug man!! My boyfriend and I were out deer hunting recently and he can across a unique critter that you may enjoy. Neither of us have ever seen anything like it and was wondering what you may be able to find out about it for us and yourself. It has yellow spine like things on it with what looks like red on the back and a green belly and legs. Any ideas???

Dear Bugman,
My friend found this green bug on the windshield of his car in Jacksonville, Florida this week,( early September). We’re wondering if you know what kind of bug it is?
Thanks so much,

Saddleback Caterpillar

Saddleback Caterpillar

Hi Glenn,
The stinging capabilities of the Saddleback Caterpillar,
Acharia stimulea, are well documented online.  According to BugGuide:  “Caterpillars are capable of inflicting lasting and painful stings with their spines.”  According to Featured Creatures:  “Acharia stimulea is best known as a medically significant species. The large spines and potent hemolytic venom rank it as one of the most important North American species of urticating caterpillars, with larvae from the moth family Megalopygidae being the only lepidopterans considered more dangerous (Scott 1963, 1964; Durden and Mullen 2009; Hossler 2010).  The spines of A. stimulea are strong, acutely pointed, and hollow. They embed deeply into tissue and break off, and can interrupt healing as the protoplasm from the venom glands dries into the tissue area (Gilmer 1925). The venom itself can cause a systemic condition called erucism or acute urticaria, for which severe symptoms may include migraines, gastrointestinal symptoms, asthma complications, anaphylactic shock, rupturing of erythrocytes, and hemorrhaging (USAF 1982, Hossler 2009).  Physically manifested symptoms may or may not be present with erucism (Hossler 2009). Contact dermatitis caused by A. stimulea includes immediate intense burning sensations around the contact zone, arector pili muscles tightening causing hair to stand on end, increased perspiration in the affected area, red blanching of the skin, and blistering (Edwards et al. 1986; Hossler 2009, 2010). Symptoms can last for five hours, and leave red blotches in the envenomation site (Hossler 2009).”

Thanks so much!

Stinging Rose Caterpillar

Stinging Rose Caterpillar

Dear Sarah,
Handle the Stinging Rose Caterpillar,
Parasa indetermina, with caution, as it is capable of producing a painful sting.  Interestingly, BugGuide does not list maple among the food plants, which are listed as:  “Hosts of the stinging rose caterpillar include apple, cottonwood, dogwood, hickory, oak, redbud, sycamore and rose bushes.”
