Yellow-faced Bumble Bee (Bombus vosnesenskii)

Yellow-faced Bumble Bee (Bombus vosnesenskii) foraging on Dune Lupine (Lupinus chamissonis)

The western United States is home to many unique and useful insects. Regional gardeners are starting to appreciate the importance of native pollinators, in part due to the activities of National Pollinator Week (the 3rd week in June).  To learn more about pollinators in general see our June 2013 posting (

The larger insect pollinators are among the more interesting visitors to S. California gardens.  One of our favorites is the Yellow-faced Bumble Bee (Bombus vosnesenskii).   This large native bee can be seen from spring to fall in west coast gardens from British Columbia, Canada to Baja California, Mexico.   In our gardens and natural areas at CSUDH, we most commonly see them from June through August.
