Lophocampa maculata caterpillar
I am doing a research project on this species and I find this photo very interesting. Ruth gravanis, would you please contact me so I can inquire about the details. It would really help the project to have an email conversation.

Thank you.

spotted tussock?
Possibly a spotted tussock, the info page shows variations in the larvae across the u.s. with the western larvae looking like yours.

Thank you, Joe and John. About a hundred feet away was another moth larva that looked exactly the same (to my untrained eye) except that there were only two spots instead of three, and they were long rectangles, perpendicular to the body.
