Are there any dung beetles native to the Pacific Northwest?

Specifically any native to Western Washington state? Any links/pictures of them would be greatly appreciated.

I'm a permaculture farmer, and dung beetles are something I'd very much love to have on my farm.

Because so much of Washington state was covered by glaciers during the ice age, I kind of doubt we have native dung beetles. Most of that type of insect life (like worms) were scraped away, by the weight of the glaciers.
