B. occidentallis
Once common to the area with there numbers representing at least 25% of the bumble bee population. In 1998 this species disappeared from the Puget Sound region. Several nests of these were removed prior to 1998. In 2012 there were reported sightings in a park in the Seattle area and also on the Olympic peninsula. In 2013 there were more sightings in these same areas. Looks like they are slowly making a comeback. If you see them please let us know where you saw them and when this was. Several species have declined across the country with concerns for their survival.
