Coastal dune Bombus from San Francisco - Bombus - Male
Lobos Creek, Presidio, San Francisco County, California, USA
July 12, 2019
I'm thinking this is either B. caliginosus or B. vosnesenskii...perhaps it would be best placed "here"?

I counted 11 flagellomeres and see no corbicula, and thus figure this is a male.

It's seen here nectaring on Eriogonum latifolium.
