Hi Bugman!
I’m a preschool teacher who recently went to Iguazu Falls on the Argentinian side. While there, I saw 2 bugs. One is the caterpillar below and the other was a spider. Unfortunately, I was unable to get a picture of it. It was black had very skinny legs its body was slightly smaller than a dime and was almost triangle shaped. I saw it crawling on the ground by itself and did not notice any webs around it. I know that is not the best description, but any info would be great as I would love to teach my students about both of these amazing creatures.
Thanks so much for your help!!

Tussock Moth Caterpillar

Tussock Moth Caterpillar

Hi Beth,
We don’t know the species, but we believe this is a Tussock Moth Caterpillar because of its resemblance to some North American species in the genus
Orgyia.  Many species have utricating hairs, so they should be handled with caution.  You can see more examples of North American species on BugGuide.  Without a photo, we can’t say much about the spider.

  1. These are so cool! I saw one in my backyard in Michigan years ago.

  2. I’m not that sure, but I think it’s Carales astur.
