Bees, including honey bees, bumble bees, carpenter bees, leafcutter bees and sweat bees, along with other pollinators, share the pollen and nectar in the half-acre bee friendly garden.
Native pollinator specialist Robbin Thorp, emeritus professor of entomology, has logged some 50 different species of bees in the garden since its inception. He began a baseline monitoring process when the garden was a field of weeds, instead of dreams.
Today we spotted a yellow-faced bumble bee (Bombus vosnesenskii)
and a honey bee sharing a purple coneflower (Echinacea purpurea). Minutes later, a honey bee and a sweat bee occupied another coneflower.
The garden, planted last fall, changes daily, which it is meant to do. When the grand opening celebration of the haven takes place from 10 a.m. to 2 p.m. on Saturday, Sept. 11, expect to see scores of visitors--both humans and pollinators--sharing the garden.
Nature's creatures are nature's features at the Solano County Fair, Vallejo, being held Wednesday, June 23 through Sunday, June 27.
Creative exhibitors, in a "this-bug's-for-you" mood, transformed butterflies, ladybugs and bumble bees into arts and crafts projects being displayed in McCormack Hall. The fair is located at 900 Fairgrounds Drive.
You'll see butterfly-inspired quilts, an educational ladybug display, a table-setting dotted with ladybugs, and huge paper mache bumble bee smiling from ear to ear--oops, from antenna to antenna.
If a county fair is a place to educate, inform and entertain--and it is--these displays do just that.
Sometimes folks think of pollinators only during National Pollinator Week, (under way this week through June 27), but it should be an every-day occurrence.
To appreciate and protect them, we need to be reminded of their existence and their role in our environment, our world and our lives.
Everybody loves a bumble bee.
Especially the yellow-faced bumble bee, Bombus vosnesenskii.
And especially a queen.
Native pollinator specialist Robbin Thorp, emeritus professor of entomology at the University of California, Davis, and first-year entomology graduate student Emily Bzydk collected a few native bees to show visitors at the Bohart Museum of Entomology during UC Davis Picnic Day last Saturday.
One of the bumble bees: a regal queen.
When Picnic Day ended, they kindly let me take her home to our tower of jewels (Echium wildprettii), a biennial plant that looks somewhat like a red-jeweled Christmas tree. "Tower of jewels" is indeed a fitting name. It towers (nine-feet high) and it sparkles like rubies.
We placed the lethargic queen on a blossom and fed her honey for quick energy. She quickly sipped about an eighth of a teaspoon, buzzed me twice (Hey, I'm your friend!), returned for more honey, and then took flight.
The queen circled the plant twice and was gone.
From the Bohart Museum display to a showy tower of jewels--all in one day.

Flight of the Bumble Bee
The bumble bee population is declining and some species are teetering on the brink of extinction.
That's the gist behind why three conservation groups and bumble bee researcher Robbin Thorp, emeritus professor of entomology at UC Davis, are asking the federal government to impose regulations on the movement and health of commercial bumble bees to protect the declining native/wild bumble bee population.
A Jan. 12th press release issued by the Xerces Society for Invertebrate Conservation is drawing worldwide attention. The latest coverage came from the New York Times and the Washington Post.
Take Franklin's bumble bee. That's a bumble bee found only in a small stretch of southern Oregon and northern California. Robbin Thorp, a member of the Xerces Society, hasn't seen it for several years and fears it may be extinct.
You'll want to read the article on "Bumble Bees in Decline" on the Xerces Society Web site and look at the photos of the bumble bees that could be nearing extinction.
Two recent studies provide a direct link between diseases in commercial bumble bees and the health of wild bumble bees:
--Otterstatter, M.C., and J.D. Thomson. 2008. Does Pathogen Spillover from Commercially Reared Bumble Bees Threaten Wild Pollinators? PLoS One. Available online at http://www.plosone.org/doi/pone.0002771
--Colla, S.R., M.C. Otterstatter, R.J. Gegear, and J.D. Thomson. 2006. Plight of the Bumblebee: Pathogen Spillover from Commercial to Wild Populations. Biological Conservation 129: 461-467.
Otterstatter and Thomson note that wild bumble bees near greenhouses have higher pathogen loads (of Crithidia bombi and Nosema bombi) than bumble bees farther away from greenhouses.We're glad to see this kind of research under way and the proposed restrictions sent to the USDA. We need to protect our wild bumble bees.
Franklin's Bumble Bee
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.
