Don't Do It!
This is the furry puss caterpillar of Megalopyge opercularis, the Southern Flannel Moth, and it is considered to be the most venomous caterpillar in the United States.
Must be the season for me to see weird bugs
As I've learned from experience, if a caterpillar is fuzzy, spiky, or begging to be petted, you should avoid it like the plague or be prepared to face Pain. Or as WIRED put it: Never Touch Anything That Looks Like Donald Trump's Hair.
This worm had an interesting brown stripe along its back, which included the tail. Looked like a Mohawk haircut. It was crawling around the withered top of a spider lily in my back yard, perhaps looking for a place to attach itself prior to morph into THIS.
