LOGAN, Utah, Feb. 9 (UPI) -- The western bumblebee, Bombus occidentalis, is one of 30 species of bumblebees living in western North America. Until the 1990s, it was the most common variety in the Pacific Northwest.
But in the mid-1990s, its population began to suddenly shrink. Over the last two decades, it has become one of the rarest. New data, however, suggests the western bumblebee is making a comeback.
