Milkweed Tiger Moth Caterpillar

What is it?
We have found three or four of these caterpillars in our back yard here in Lima, Ohio. We have searched several web sites and feel that it is not exactly like the Spotted Tussock Moth caterpillar. This one has black spines as well as the white, and the orange on its back appears almost woven They have been happily munching away at our milkweed. Is it a variation of the Spotted Tussock, or something else? Thanks for any help you may provide. Sincerely,
Cheryl and Earl Fisher
P.S. Our granddaughter calls these critters ‘callipitters,’ which I find quite amusing!

Hi Cheryl and Earl,
This is a Milkweed Tiger Moth Caterpillar, Euchaetias egle. It is also called a Harlequin Caterpillar as well as a Milkweed Tussock Moth Caterpillar.
