Thar’s gold in them thar hills.
And also bumble bees.
If you visit the Sonoma County coastal town of Bodega Bay, and drive up to Bodega Head overlooking the ocean, you’ll see a carpet of gold flowers known as coastal goldfields or Lasthenia minor.
And you’re certain to see bumble bees nectaring those flowers.
Noted bumble bee expert Robbin Thorp, emeritus professor at UC Davis, says the most common species of bumble bee at Bodega is the yellow face bumble bee, Bombus vosnesenskii. The second most common? Bombus bifarius.
Goldfields are natives and so are bumble bees. Goldfields belong to the Asteraceae family, also known as the aster, daisy or sunflower family.
Want to learn more about bumble bees? Bumble bees are very much in the news. Thorp wrote a piece for a UC Berkeley publication. He recently addressed the Smithsonian Institute on the plight of the Western bumble bees and gave a Webinar at the UC Davis Department of Entomology on Franklin's bumble bee, an insect he fears may be extinct.
Gordon Frankie, Robbin Thorp and colleagues also wrote the lead story on native bees, featured in the latest edition of California Agriculture.
It's good to see the plight of the bumble bees drawing so much interest and it's good to see all the bumble bees at Bodega Bay.

The Smithsonian Institution is the place to "bee" on Monday, June 22.
The location: Baird Auditorium, National Museum of Natural History. The Smithsonian is located at the corner of 10th Street and Constitution Avenue NW, Washington D.C.
Thorp will discuss "Western Bumble Bees in Peril." Sydney Cameron and Jeff Lozier of the University of Illinois will examine "The Status and Trends of Midwestern and Southern Bumble Bees." Then Leif Richardson of the Vermont Department of Fish and Wildlife will cover "Bumble Bee Trends in Northeastern North America."

- Paul Williams, Natural History Museum, London, "A Global View of Bumble Bees and Their Conservation Status."
Michael Ruggiero of the Smithsonian Institution will moderate. He's the senior science advisor of the Smithsonian's Integrated Taxonomic System (ITIS).
Following the symposium, bumble bee experts and other scientists will continue to meet at the Smithsonian for the next two and a half days to discuss concerns about the declining bumble bee population.
The symposium is part of National Pollinator Week, which starts Monday, June 22 and continues through Sunday, June 28.
Thorp delivered a presentation on Franklin's bumble bee May 27, during one of the UC Davis Department of Entomology's noonhour sessions. Franklin's bumble bee, feared extinct or nearing extinction, is found only in one part of the world: southern Oregon and northern California. Thorp's talk was Webcast.
Thorp, a member of the California Academy of Sciences since 1986, says that the loss of a native pollinator "could strike a devasting blow to the ecosystem, economy and food supply."
Locally, we've noticed far fewer bumble bees than in past years. Last summer we spotted a few in the UC Davis Arboretum (see below). This is the yellow-faced bumble bee or Bombus vosnesenskii, the most common Califonria bumble bee.
Not so common any more.
