Poisonous caterpillars

When I moved to Trinidad, people warned me about the fer de lance and coral snakes, scorpions and centipedes. Nobody told me about poisonous
caterpillars. Yesterday morning, I saw something orange and furry on a twig in the plum tree so I went to get a better look. I reached up for the end of the
limb and slowly pulled the branch down to see it… I didn’t have a chance to touch it before it fell off and barely brushed my fingers on the way down. Intense stinging. I went inside and washed my hand and the pain got worse and worse. Then it radiated up my arm to the glands in my arm pit. I sat down, worrying a little whether I was going to stop breathing or my heart would stop. I tried antihistamine cream, aspirin, ice, etc. and the pain got worse - it wasn’t a sting anymore - just intense pain. The PAIN DID NOT WEAKEN OR DISSAPATE EVEN A LITTLE UNTIL AT LEAST FIVE HOURS LATER. Later that night, my knuckles and elbow still ached and I even had some pain in my legs.

When I described this to Trinidadians, they said, “Oh, it’s a Chinney - you should never touch those.” But when I showed it to people, including people in their 60s who grew up near where I live (in Maraval, in the mountains just outside Port of Spain, Trinidad) no one had ever seen anything like it.

I’ve identified what I think stung me from these websites: Puss Caterpillars Megalopyge opercularis and this one. However these sites describe the North American Puss Caterpillar. They say it ranges in size from 3/4 inch long to 1 1/4 inches long and that “the severity of the sting is more intense, the larger the caterpillar.” The one that got me is at least three inches long and looks something like a moussed and blow-dried hamster. I’d like to hear from any caterpillar experts (Doug?) here about what is known about this variety.

Perhaps it was Megalopyge bissesa?

Some morphs:

I’m afraid I know little about their range and less about larval size.

Hopefully Colibri will wander by soon.

If this toxin is so potent why don’t they find out what it is?

I dunno, but I sure hope North Korea doesn’t get ahold of it. Or the U.S. govt. either, for that matter.

Tamerlane, that third picture looks like it, but couldn’t tell the size from the picture.

While reading your experience i recalled a story my grandmother told me years ago about her run in with an “asp”, i called her over to the moniter and showed her the pictures on the link provided…we have a postive match! She certainly does NOT look back on the experience fondly and describes the pain as utterly excruciating.

Sorry you had to experience that, but if anyone has any more info on these little buggers please share, my intrest is perked.

By the way, it seems the majority of the critters are in Texas, right around my neck of the woods…lovely.

That first website I gave you has a section on Puss Caterpillar Encounters. When my friends here read that, they realized I wasn’t exaggerating to get more sympathy.

Nothing cogent to add to the valuable data posted, but given that description, my guess is that it’s the little guys’ revenge for your having left the moderating staff (though not the SDSAB) here. :wink:

That’s really cool and yet freaky at the same time.

Any info on the range of these critters? The page only said one of 50 found in the states. How far north are these things found?

Actually, this thread mas making me think about posting a question about “asps.”

Yes, I live in Texas.

Are they called this elsewhere?

“Asp” is a name that is used in Florida to Texas, according to that website. Again, MY caterpillar is BIGGER and WORSE than the ones you have there. I still have not found a single Trinidadian who has ever seen one of these before. It’s on my desk at work (in a secure enclosure) and I will let you know as soon as I get it specifically identified.

(Actually I’m haggling with my ex-landlord about giving me back my rental deposit and if he doesn’t give it to me, I’m thinking of dropping it down his shirt.)

Based on the linked picture, you could glue it to a stick and tell him it’s a Q-tip.

Not that this will add significantly to understanding of the situation…but my ex’s late grandfather lived in Trinidad back in the '60s, and owned two pet spider monkeys that he smuggled in from South America. One died after eating a poisonous caterpillar…perhaps it was of the same species as JillGat’s monster?

Unfortunately, as my ex-grandfather-in-law is also no longer with us (not, I am quick to point out, as the result of poisonous caterpillars), I can’t ask him to identify the fatal bug.

A Q-tip the size of a hamster. Or maybe tell him it’s a corndog. Mmmm.

There are tons of stinging caterpillars in South America; however, the “moussed hamster” look only applies to a few genera of megalopygids. So, your beastie was probably either a Megalopyge (of a different species than opercularis or any other US type) or a Podalia species.

For the, you know, bum.

Very interesting thread. I never realized such catepillars existed.

Slight nitpick: aren’t these catepillars venomous, not poisonous?

Yes, you are correct. In fact that is the best way to search for info. on the internet about these things, “Venomous caterpillars.” They are probably also poisonous, but I had a big breakfast so I’m not going to eat it yet.

Well, technically they are poisionous too, as my ex-wife’s grandfather’s pet monkey (that almost sounds like an urban legend) found out to its peril.

Does that mean they canswim!?
