This moth is found in North America, from east of the Great Plains in the United States to northern Mexico and from Saskatchewan eastward through central Quebec to Nova Scotia in Canada. Luna moths are common as far south as Seminole County in central Florida.

They unfortunately don't inhabit my country, but they are quite a beautiful sight to behold. Nice find @gogogadgetupvote
I have never seen any butterflies or moths like that in the Pacific Northwest. What part of the world are those Luna Moth's from?

Yes, I was petting it so I could get a picture of it's wings open.
That's a male eastern tiger swallowtail.
