Don't you just love watching bumble bees?
This morning we watched a yellow-faced bumble bee (Bombus vosnesenskii) foraging on lavender. It moved quickly from one blossom to another, barely allowing us time for a "bee shoot." It was "bee gone" every time we aimed the camera.
Finally, it cooperated.
Native pollinator specialist Robbin Thorp, emeritus professor of entomology at the University of California, identified it as a male, the first (photo of a male Bombus vosnesenskii) he's seen this season.
He thinks a prize is in order.
Thorp, co-author of the newly published Bumble Bees of North America: An Identification Guide (Princeton Press), and Davis photographers Gary Zamzow and Allan Jones and yours truly usually have a friendly competition to find and photograph the first bumble bee of the year, of the month, of the day, of the minute. Well, almost. It's "Bumble Bee Alert" a lot. On Christmas Day, I managed to capture an image of a black-tailed bumble bee, Bombus melanopygus, foraging on jade blossoms at the Benicia Capitol State Historic Park, Solano County. (The black-tailed bumble bees emerge much earlier than the yellow-faced bumble bees.)
Now a Bumble Bee Watch group has launched a website to track bumble bee populations across the U.S. and Canada. This is a collaborative effort among several conservation groups and universities, according to the website and they need your sightings, including photos. As a spokesperson said: "The information will help researchers determine the status and conservation needs of bumble bees, and help locate rare or endangered populations. They will also help with identification!"
Well, today, I watched one male Bombus vosnesenskii, and he watched me.
My prize? Just enjoying--and appreciating--nature at its finest.
(Note: How can you distinguish a male from a female Bombus vosnesenskii? Said Robbin Thorp: "Boy bumble bees have an one more segment in the antenna and the abdomen than females do. The tip of the abdomen is also more rounded. Male bees do not have any pollen transport structures. In bumble bees, this means that the hind tibia is much more slender than in females which have corbiculae (pollen baskets). In Bombus vosnesenskii there is a second partial yellow band on the abdomen on T-5."
"The most accurate test of female vs male bumble bees, is to pick up a specimen with a bare hand. If you get stung, it is a female, if not, it is a boy bee. Boy bees can't sting, because they have no stinger. But I do not recommend this test unless you already know the answer! :)"

"It was a bad hair day," quipped native pollinator specialist Robbin Thorp, emeritus professor of entomology at the University of California, Davis.
Yes, it was.
A very bad hair day.
Thorp was looking at several photos I took April 14 of a yellow-faced bumble bee, Bombus vosnesenskii Radoszkowski, 1862, foraging on rock rose (Cistaceae) at the Petaluma marina. With winds gusting at 18 miles per hour, the lone bumble bee struggled to right itself as the "Flight of the Bumble Bee" turned into "Crash Landings of the Bumble Bee."
This bee, also known as the Vosnesenskii Bumble Bee, was named by Polish entomologist Oktawiusz Wincenty Bourmeister-Radoszkowski (1820-1895) who worked in the Russian empire. It is one of the most common species near the West Coast, write Thorp, Leif Richardson, Sheila Colla and lead author Paul Williams in their newly published book, Bumble Bees of North America: An Identification Guide" (Princeton University Press).
Its habitat: open grassy areas, urban parks and gardens, chaparral and shrub areas, and mountain meadows. Indeed, the shrubby area around the Petaluma marina is perfect for bumble-bee habitat.
The authors report that the yellow-faced bumble bee likes a number of plants, including manzanitas (Arctostaphylos), ceanothus (Ceanothus), rabbitbush (Chrysothamnus), thistle (Cirsium), wild buckwheat (Eriogonum), California poppy (Eschscholzia), lupines (Lupinus), phacelia (Phacelia), rhododendrum (Rhododendrum), currants (Ribes), vetch (Vicia), goldenbush (Ericameria), godetia (Clarkia), and gumweed (Grindelia).
This little bumble bee showed a preference for rock rose, but the wind rocked its world.

If you want to learn more about honey bees and other pollinators, then “The Bounty of Pollination: More Than Just Honey” is the place to “bee” on Saturday, Oct 27 at the Robert Mondavi Institute for Wine and Food Science (RMI), University of California, Davis.
This will be the "debut event" of the Honey and Pollination Center of RMI, according to event coordinator Tracy Dickinson.
The public event, to take place from 1 to 5:30 p.m. in RMI's Silverado Vineyards Sensory Theater, is billed as “an afternoon of lively discusssions, unique tastings and interesting displays on the science behind honey and the important (and surprising) non-honey bee pollinators."
RMI is in the process of lining up speakers and displays.
Registration opens in August. The cost per ticket is $60, with discount prices offered for UC faculty, staff and students. The last day to register online is Friday, Oct. 26.
UC faculty staff and students may obtain a coupon code for discounted tickets through firstname.lastname@example.org. Or, if folks want to become a Friend of the RMI, they need to contact Kim Bannister at email@example.com.

Native on native.
That's when you get when you see a yellow-faced bumble bee (Bombus vosnesenskii) on a penstemon, also known as "beard's tongue."
Both the bee and the flower are native to North America.
Native Americans reportedly used the penstemon, formerly classified in the Scrophulariaceae family and now considered a member of the Plantaginaceae family, to relieve toothaches.
Whether it relieves toothaches or not, the penstemon, with its two-lipped tubular flowers, is quite attractive to bumble bees!

Training for the Olympics?
If you step into your garden in the early morning, you might see a male bumble bee sleeping on one of your plants. The females return to their nests at night, but the males don't. They stage slumber parties, aka sleepovers, on your plants.
If they look bedraggled, that's because they are. It's the beginning of a bad hair day.
Such was the case when we encountered this male yellow-faced bumble bee (Bombus vosnesenskii) on the lavender.
As the sun began rising, Mr. Bombus vosnesenskii, too, struggled to rise. Had he been partying all night? Sipping too much nectar, perhaps? Rolling in the pollen?
He crawled along the lavender plants , backtracked, and then appeared to be using a stem as a chin-up bar.
Nothing like a little morning exercise...
