Caterpillars can be deadly

About 30 years after the incident my wife has calmed down enough to where she suggested I write about how dangerous caterpillars are. Interviewing her and her sisters and doing some research I came away with a healthy respect for these animals.

Incident 1.
She was about 4 years old, living in the mountains east of Chiang Mai. She came out of the bushes to note a blue and white very fuzzy caterpillar on her arm. They are about 2 to 3 inches long; the body 1/4 to 1/2 inch thick and the spines making it about 1 inch thick. Wearing a traditional Hmong skirt a search revealed she had several more on her legs. Onset of incident was unclear. Her arm was described as unrecognizable. She lost consciousness.

Her mother had to carry her on her back through the jungle for about 4 kilometers out to the road and flag down a ride. It took another half hour to get to the hospital. She was, approximately, entering clinical death. In a coma and without respirations. She was on a respirator for approximately 1 week before regaining consciousness. To this day the sight of a caterpillar will send her straight up a wall. This is a woman who tries to kiss our monster sprassids and lycosids and casually cajoles kraits off the roadways with her foot.

Incident 2.
A friend has a certain kind of palm like plant with leaves about 2 to 3 feet long. The caterpillar that eats these leaves grows to 4 to 5 inches long, is blue white, and has huge fantastic shaped spines making it overall about 1 1/2 to 1 3/4 inches thick. One caterpillar can strip an entire 2 foot by 6 inch leaf to just a stem in about 1 hour. He brushed against one. In a second he said his arm felt like it was on fire. He nearly passed out within a few minutes and became literally blind with pain and unable to walk. I arrived about an hour after initial contact. He was acutely diaphoretic, the extremity was roughly twice normal size with extreme pitting edema close to splitting the skin, had abdominal spasms so powerful they precluded vomiting, a fever of approx 106, and muscle tremors, primarily in his legs and hands. I administered epi IM then IV some minutes later as he appeared to be in respiratory distress. In the hospital he was catheterized and given 1 liter NS wide open then 2 liters Glucose and another liter NS with unknown allergen agent(s). Symptoms receded to normal health condition in 18 hours except for acute to extreme touch pain in the affected extremity which receded over a 5 day period.

I now read that caterpillars kill almost as many people as recorded documented cobra bites. So, consider taking those cute fuzzy ones you aren't familiar with very seriously when encountered.

Huh, thats pretty crazy. Where are you located?
My guess is that he is from Thailand, since he lists it as his location haha.

I lived in Georgia and our backyard was FULL of caterpillars. We would catch them by the hundreds, but my brother would always squish them. He called them popos for some reason haha.

Wow that's fascinating! Thanks for sharing. Glad your wife and friend made it out of those terrifying situations!

Would you happen to have links to the articles you've been reading? I'd love to learn a little more about this.

That's pretty crazy! Here in 'Merica our caterpillars are about as dangerous as a hard tooth brush :D.

Exactly. When I first came here and encountered peoples fear of caterpillars I didn't take it seriously. I thought they were like the average spiderphobe going freak over a pholcid.
I fully admit to being very uninformed and stupid when I first came here. I was shown a massive hematoma that looked like the patient had been struck by a car or a solid kick from a horse. It covered about 90% of the anterior of her thigh from groin to knee. But it was so acutely painful I couldn't palpate for a broken bone. It couldn't believe it was just a brush up against a caterpillar.

What makes these animals even more of a hazard is some of them are harmless except at certain times of the year, some are harmless yet have identical twins that are dangerous and so on. They are so diverse and many spectacular in appearance!

Here are some of the links I checked out.

Um,not exactly.When I was growing up in Indiana,my mom found a bunch of really pretty caterpillars chewing on one of her fave plants.She picked them off bare handed.well,she ended up in the hospital with hands the size of Honeybaked hams.If you don't know what it is,don't touch it! Here is a pic....( They are really cool looking) http://bugguide.net/images/cache/Y0...KHS1QF0GK30GK9KGKUKLKC0BQRS6QPKLK2KLKB06Q.jpg :eek:

Wow, can you mail me some of those? haha. I was stung a lot when I was a kid by what's called the Puss caterpillar on the internet. Locally they are called "asp caterpillars". It hurt but it didn't hurt me nearly as bad and claims on the internet, with vomiting and headaches, I'd say those are rare reactions. To me it was something between a honey bee and wasp, not as bad as a wasp. That large caterpillar sounds pretty nasty.

This, non or minimal reaction to caterpillar toxins apparently is something almost unique to those animals. There are several factors with caterpillars that affect the toxins that they carry that aren't normally found in any other animal. The time of year and what the caterpillar has been eating can significantly alter some of their toxins.
However, the payload delivery mechanism remains mostly unaltered and, like jellyfish, there is no such thing as immunity or resistance to the toxins. Consequently, if a person does get zapped by one that is known and well established for severe reactions without developing those reactions, special note should be made of all environmental factors as well as a comparison to other nearby caterpillars of the same species.

Yes, yes..., however, as far as the asp/puss caterpillar here, their danger was GREATLY exaggerated as a kid. I've never heard of anybody dying from contact with an asp caterpillar. That was mood of the talk, as if you will go to the hospital for a few days, ...every time. It's kind of like when kids are taught not to touch mushrooms because a relatively few are poisonous. To make sure of the kids safety, the parent often tells their kids they are all poisonous, then they grow up with a fear of mushrooms in general. You see it here often, "There is a mushroom in my .... terrarium, will hurt anything.." But I know, all Puss caterpillars can sting but I know of nobody that has had such severe reactions as posted, possible but probably rare reactions. Of course keep in mind I'm only talking of this sps.

Right. As with other critters the actual number of deaths is minute to just getting some degree of sick. I think the only animal in the world that has a very significant number of deaths to just getting sick is the cone shell. But the Lonomia is pretty darned close and if a person bumps into a bush filled with them the chances of survival aren't good.

Read about that cone shell, documentaries, very interesting creature there, a fish eating snail, not the norm for sure! Even with Lonomia though, as I just got through reading about, a few deaths a year, which is of course too many, but still rare in the big picture. I know you are in the med field as you have expressed, I grew up around only one result of that. I saw doctors exposed to extreme cases, that's just the nature of the job. Over time it changed them some how. They would think, "..what if..." because of what they had seen in the ER and in their practice, when what they saw was usually not the norm. They became hyper-cautious, extremely careful. Risk was not an option in areas of their life. Not that you are going there, this only reminds me of that, it's interesting to sit back and at least think about for me.

You've mentioned what I call the great divide. J. Q. Public vs the emergency responder. JQ's life is immersed in trivialized violence which strongly enforces the attitude 'It can't happen to me' and the responder that see it can and does happen on a daily basis. We are worry warts, we always look at the dark side. You, average TV/movie viewer has seen several thousand people get shot. Ho hum, no big deal. I still see my bullet ripping a suspects leg off. You see the mega violent explosions. I've smelled crispy critters. A term we coined to warn other responders of a burned beyond recognition body that should be approached only holding your breath or wearing an SCBA. You see the actions, canned and packaged, from the comfort of a couch. We see the consequences, feel the gravel digging into our knees as vehicles race passed, see the looks on the faces as they realize it's the end of the road for a loved one.

There is no middle of the road. It's an irreducible conflict of POVs.

I don't watch TV and was just in a pretty bad wreck last week, but yeah, developments of POVs, I know what you mean, just the way it is. ..Not sleepy and was thinking so got up to add this. The strangest thing I hear people say when something bad happens to them is, "Why me?" If they ask that they should then ask, "Why not me?" It does ring to your point about the mindset of people in general, but I'm not that way. Stuff happens, it may be rare, but it does happen. The wreck, it was my fault, not paying attention only for 2 seconds in the rain. "Why me?", because I'm no different, I'm human. I remember the flash of reality that hit my mind, no words, only pure imagination and thought: "You're going to hit this truck, it's your fault, accept it, deal with it, make sure everybody is OK ...BOOOM! What a nightmare, first time for me.

I was at the Great Barrier Reef listening to an official guide explaining about the cone shells. Only people with leather hard soled shoes were allowed on that stretch of beach. There were a lot of giggles. Later that day we heard the ambulances. 1 man got zapped by a box jellyfish and one girl got hit by a cone shell. The girl was in a coma.

I helped compile a photographic essay of cluster munitions being used by NATO during the Kosovo debacle. Essentially we took the occupation of the person, their activity at the time of the incident and the nature of the wounds to produce proof positive of the indiscriminate used of those munitions in civilian areas. As it turned out I had to present our findings at one location to a group of about 25 people. The people became furious. They all walked out. They weren't furious about the munitions but at me for showing them the realities. NONE, not one vented about the innocent civilians maimed. just that their sensibilities were offended.

People in the modern world are brainwashed and hypnotized. Fully programmed by industrial and commercial vested interests. Show them a spider bite and Pavlov's dog, they start salivating nonsense. Thinking for themselves and reasoning is not just downplayed, it's forbidden. You might buy someone elses product. You might object to the government slaughtering innocent civilians.

Sorry to hear about the wreck. Hope no deaths or lasting injuries.

That's a pretty crazy pillar. I never saw anything like that. I've handled thousands and thousands as a kid. Never had a problem. Probably would have avoided that crazy looking thing though lol.
