Western Bumble Bee (Bombus occidentalis), photo by Jeremy Gatten
The Xerces Society provides good detail on this rare species, including the following information: "These bees can still be found in the northern and eastern parts of their historic range, but the once common populations from southern British Columbia to central California have nearly disappeared. This bumble bee is an excellent pollinator of greenhouse tomatoes and cranberries, and has been commercially reared to pollinate these crops. In the past, it has also been an important pollinator of alfalfa, avocado, apples, cherries, blackberries, and blueberry."
