It's a brief appearance but the message is important.
Pollination ecologist Neal Williams, assistant professor of entomology at UC Davis, appears briefly in a segment on native pollinators produced by America's Heartland. The show is now airing throughout the country. (Watch video)
Reporter Sarah Gardner of America’s Heartland touches on the declining population of honey bees--which European colonists brought here in 1622--and native pollinators, which are also declining.
“Farmers, scientists and others in U.S. agriculture are mounting an effort to develop a unique pollinator partnership promoting the growth of native plants on farms, orchards and ranches all across America,” Gardner said.
Williams is quoted as saying: “In the East, native bees can potentially provide all the pollination that’s necessary in the vast majority of those farms.”
It's great to see the focus on pollinators!
Gardner interviewed Mace Vaughn of the Xerces Society for Invertebrate Conservation; Ernie Shea of the Native Pollinators in Agriculture Project; and A. G. Kawamura, former California Secretary of Agriculture, among others.
Vaughn said that “unless we encourage native pollinators, consumers are going to see fewer food choices and higher prices. The conservationist is urging farmers and growers to add native plants to their growing areas in an effort to attract different bee species, butterflies, hummingbirds and other animals that can help in cross pollinating crops.”
Williams, who joined the UC Davis Department of Entomology in 2009, was a featured speaker at the International Symposium on Pollinator Conservation, held last January in Fukuoka, Japan. He explored agricultural landscape change and the role of bee life history in predicting and understanding responses of bee communities.

What an unexpected find!
It was the first day of 2013 and what did we see: a queen bumble bee, Bombus melanopygus, aka black-tailed bumble bee.
Like scores of others, we decided to take a walk on Jan. 1 in the Benicia State Recreation Area. Located in Solano County, just outside the city of Benicia, the 447-acre park on State Park Road offers a view of the Carquinez Strait amid lush grasslands, rocky beaches and a marsh filled with cattails about to lose their charm as they go to seed.
It's a good place to walk, run, cycle, and engage in picnicking, fishing, and bird watching.
And bee watching.
When the temperature hits 55 degrees, it's common to see honey bees foraging among eucalyptus, manzanita and wild mustard this time of year.
In mid-morning, Jan. 1, the temperature registered 50 degrees. No honey bees did we see. But as we stopped to admire the manzanita in the native plant garden, we spotted her: a black-tailed queen bumble bee, as later identified by native pollinator specialist Robbin Thorp, emeritus professor, UC Davis Department of Department.
"Yes, a queen of Bombus melanopygus, earliest of our bumble bees to emerge from hibernation and start nests each year," Thorp said. "I had heard that some were flying in December in the Bay Area. Keep an eye out for the first workers or first queens with pollen loads. Those will be the signs that nests have been established. Otherwise, seeing queens out on a nice sunny warm day, even sipping nectar, may mean that they are just stretching their wings and checking things out between naps, before getting down to the serious business of starting a new nest."
This species of bumble bee is native to western North America and is found from California to British Columbia and as far east as Idaho. "In the southern part of its range, the third and fourth segments of the abdomen are black instead of the red color seen in the northern populations, and this black color form was formerly known by the name Bombus edwardsii," according to Wikipedia.
Now it's Bombus melanopygus.
Soon we saw that we were not alone. Several other queen bumble bees quietly appeared, all to sip the sweet nectar of manzanita on the first day of 2013.
Soon we expect to see them with a load of pollen.

Art Shapiro knows where to find the cabbage white butterflies (Pieris rapae).
No sooner had he announced his annual "Beer-for-a-Butterfly" Contest, then he found one. Actually, two.
Shapiro, distinguished professor of evolution and ecology at UC Davis, has sponsored the annual contest since 1972 to draw attention to the butterfly and its first flight. He's been monitoring butterflies for more than three decades.
He awards a pitcher of beer (or its cash equivalent) to the first person who collects the first cabbage white of the year in a three-county area: Yolo, Solano and Sacramento.
Tuesday, Jan. 1 2013 dawned rather cold. Not to worry. That afternoon, at precisely 1:18 p.m., Eureka! Shapiro collected a cabbage white near a railroad embankment in the Yolo County city of West Sacramento and spotted another at the same site.
“At 1:29 p.m., I saw a second rapae there but did not pursue it,” Shapiro said. “I figured that by the time I got near it, it would be somewhere else, so I let it be. The one that I took is unambiguously of the fall brood, based on phenotype--though it appears to have emerged today. Rapae was still flying here Dec. 17 and Dec. 24, so I was not entirely surprised to find it today.”
Of the contest, Shapiro said: “I do not close my beer contest if the fall brood slops over. So the contest is still open and will be until someone gets an actual example of the 2013 brood! Which, I suspect, will not be for 10-14 days...but I'll be looking, especially since the computer models are forecasting the next two weeks ‘dry.’
Shapiro related the details of his find. “Our family traditionally attends a New Year's Day party in Sacramento, regardless of the weather,” Shapiro said. “If the weather is good, I go in the field first--usually to North Sacramento, which is close to the party venue in Boulevard Park. But this year I went to West Sac instead, advisedly, because I was intensely curious whether rapae would indeed be out.”
“The wind was biting and made it feel colder than it was, but West Sac is wind-sheltered (the railroad embankment) and the south-facing slope was 50 degrees when I arrived at 11:45 a.m. It eventually topped out around 55-56 and actually felt warmer."
The cabbage white butterfly inhabits vacant lots, fields and gardens where its host plants, weedy mustards, grow. Shapiro saw some wild radish (Raphanus) in bloom, but no wild mustard (Brassica) in bloom. The first butterfly he saw was a Red Admiral (Vanessa atalanta) flying “from south to north, lickety-split.”
At 1:18 p.m. he spotted a rapae flying rather unsteadily parallel to the service road. “I lost it momentarily, then spotted it body-basking on a wild mustard leaf and caught it easily. It was a male of a typical late-autumn phenotype, heavy black pattern above, underside of hindwing bright yellow with a sprinkling of gray scales.”
“And it was incredibly fresh--the wings seemed soft, and one forewing got outside its corresponding hindwing in the net. This is something that happens occasionally with newly hatched bugs that are not fully ‘hardened’--I was afraid it might break off! I think it must have emerged today, and I got it on its maiden flight."
Shapiro, who usually wins his own contest, snagged the first cabbage white butterfly of 2012 at 11:50 a.m. on Sunday, Jan. 8 in West Sacramento. He caught the first cabbage white butterfly of 2011 at 1:21 p.m., Monday, Jan. 31 in Suisun City, Solano County.
Meanwhile, the contest is still under way, pending the declaration of a winner.
The rules state that butterfly must be collected outdoors in one of the three counties and delivered live to the office of the Department of Evolution and Ecology, 2320 Storer Hall, during work hours, 8 a.m. to 5 p.m., Monday through Friday. All entries must list the exact time, date and location of the capture and the collector’s name, address, phone number and/or email.
“The receptionist will certify that it is alive and refrigerate it,” Shapiro said. “If you collect it on a weekend or holiday, hold it your refrigerator but do not freeze it. A few days in the fridge will not harm it.”
Shapiro, who is in the field more than 200 days a year, has been defeated only three times since 1972. And all were his graduate students, whom he calls “my fiercest competitors.” Adam Porter defeated him in 1983; and Sherri Graves and Rick VanBuskirk each won in the late 1990s.

The last honey bee of 2012.
Despite the cold weather at Bodega Bay last Friday, we managed to see a few honey bees nectaring a New Zealand tea tree, aka Leptospermum scoparium.
The temperature registered 53 degrees and there they were, foraging among the dainty pink and white blossoms, as if it were spring.
As the year draws to a close, we've been inundated with words like "fiscal cliff," "spoiler alert," "bucket list" and "YOLO." (No, Yolo doesn't mean Yolo County but "You Only Live Once.")
Let's hope those words don't apply to honey bees in 2013 and the years beyond.

It's a wonderful, well-deserved honor that pays tribute to her amazing talents.
Donna Billick, co-founder and co-director of the UC Davis Art/Science Fusion Program and an artist known for crossing disciplines and borders from Davis to Central America to deliver and coax creative expressions, has been selected the staff recipient of the Chancellor’s Achievement Award for Diversity and Community for 2012-2013.
The award recognizes Billick for her “contributions in enhancing inclusiveness and diversity within the campus community," according to Rahim Reed, associate executive vice chancellor, Office of Campus Community Relations.
Billick, a self-described "rock artist," will be honored at a reception in Chancellor Linda Katehi's residence on Feb. 6. The honor includes a $500 monetary award.
“Donna is an exceptional leader who has devoted her life to creating access to the arts and sciences to the broadest communities possible,” said entomology professor Diane Ullman, associate dean for Undergraduate Academic Programs, College of Agricultural and Environmental Sciences.
Billick’s art projects not only span the campus and into area communities throughout California, but delve into Mexico and Central and South America.
“She has a remarkable ability to coach novices and help them find confidence in their artistic expression,” said Ullman, who nominated her for the award with three UC Davis Arboretum officials: director Kathleen Socolofsky, assistant director Carmia Feldman, assistant director and senior museum scientist Emily Griswold.
Indeed. We've seen Billick engage children, college students, teachers and grandparents, taking self-professed non-artists and showing them that they, too, can express themselves with art.
The UC Davis Art/Science Fusion Program, launched in 2006, is a multi-course program with outreach activities involving design faculty, science faculty, museum educators, professional artists and UC Davis students. “Participants see and feel art and science, hold it in their hands, hearts and memories—in ceramics, painting, photographs, music, and textiles,” said Ullman, who previously received the Chancellor's Achievement Award for Diversity and Community in the faculty category.
Billick's work--and the work of the UC Davis Art/Science Fusion Program--can be seen on the UC Davis campus in the Arboretum, Shields Oak Grove and the Häagen-Dazs Honey Bee Haven, among other sites.
One of the program's most spectacular projects is Nature’s Gallery, a ceramic mosaic mural showcasing plants and insects found in the Arboretum’s Ruth Storer Garden. The U.S. Botanic Garden, Washington, D.C., displayed the mural in 2007; it now has a permanent home in the Storer Garden.
Billick created the six-foot-long honey bee sculpture for the Häagen-Dazs Honey Bee Haven, and the ceramic mosaic sign that fronts the Harry H. Laidlaw Jr. Honey Bee Research Facility on Bee Biology Road.
Billick founded and directs the Billick Rock Art of Davis, a studio that has brought large-scale public art and community-built art to communities across the nation since 1977. She also launched the Todos Artes, a program providing destination workshops and community-built art in Baja, Mexico, since 2006.
An alumna of UC Davis, Billick toyed with a scientific career before opting for a career that fuses art with science. She received her bachelor of science degree in genetics in 1973 and her master’s degree in fine arts in 1977, studying art with such masters as Bob Arneson, Roy De Forest, Wayne Thiebaud and Manuel Neri.
