The article says one of the states the bumblebee has vanished from is Oregon, I'm not sure about that. I definitely saw something that looked very bumblebee like in downtown Portland multiple times this past summer. Bees in general are rare downtown, but if you're outside enough you'll see them in parks and along the Willamette river. A few miles out to the suburbs or undeveloped areas and bees (bumble and otherwise) appeared abundant in Oregon the last time I traveled that way (a few months ago).
