This little caterpillar was crawling on our car. I think it’s an American Dagger caterpillar which becomes an American Dagger moth:
It’s new home:
As to those black hairs sticking up from it’s body:
The American dagger moth caterpillar doesn’t sting like a wasp. The irritating hairs break off in the skin where they can cause hives, welts, or dermatitis. So, to avoid getting “stung,” you shouldn’t pick up these fuzzy yellow caterpillars.

It’s a beautiful caterpillar albeit not one to coddle and I’m sure he/she will enjoy the lovely home you found. Thanks for posting, I’ve always liked woolly caterpillars.

It’s startling to see something so beautiful appear so out-of-place. It’s like nature is saying, “Don’t forget about me!”
