Yes, hummingbirds are pollinators, too!
A capacity crowd of 250 will attend the fourth International Pollinator Conference, to be hosted by the University of California, Davis, from Wednesday, July 17 through Saturday, July 20 in the ARC Ballroom.
A welcoming reception took place from 6:30 to 8 tonight (Wednesday) in the Good Life Garden at the Robert Mondavi Institute, 392 Old Davis Road.
Themed “Multidimensional Solutions to Current and Future Threats to Pollinator Health,” the conference will cover a wide range of topics in pollinator research: from genomics to ecology and their application to land use and management; to breeding of managed bees; and to monitoring of global pollinator populations.
Co-chairs are pollination ecologist Neal Williams and Extension apiculturist Elina Lastro Niño of the UC Davis Department of Entomology and Nematology. The UC Davis Honey and Pollination Center, directed by Amina Harris, is coordinating the conference. Events manager Elizabeth Luu serves as the conference coordinator.
Keynote speakers are Lynn Dicks, Natural Environment Research Council (NERC) Research Fellow, School of Biological Sciences, University of East Anglia, England, and Christina Grozinger, distinguished professor of entomology and director of the Center for Pollinator Research, Pennsylvania State University, (the research center launched the pollinator conferences in 2012).
Dicks will speak at 9 a.m., Thursday, July 18 on "The Importance of People in Pollinator Conservation" while Grozinger will address the crowd at 9 a.m., Friday, July 19 on "Bee Nutritional Ecology: From Genes to Landscapes."
Dicks, an internationally respected scientist, studies bee ecology and conservation. She received the 2017 John Spedan Lewis Medal for contributions to insect conservation. Grozinger studies health and social behavior in bees and is developing comprehensive approaches to improving pollinator health and reduce declines.
Among the speakers is Rachel Vannette, assistant professor, UC Davis Department of Entomology and Nematology, who will discuss her hummingbird research.

"The Redcoats are coming! The Redcoats are coming!"
So shouted American Revolutionary patriot Paul Revere during his historical ride. Those who responded to the colonial revolt included my immigrant ancestors: the Keatleys, Laughlins and Agees.
They left their farms and took up arms.
Today, July 4, we celebrate Independence Day, remembering the American patriots from the 13 colonies that defeated the British during the American Revolutionary War, 1775-1783.
Wonder what life was like back during that time?
They grew vegetables and other crops; raised chickens, pigs, dairy and beef cattle and animals; hunted deer, elk and other game; and fished the nearby rivers and oceans. Their menu included eggs, milk, venison, bacon, bread, potatoes, fish, and rice.
And honey. Yes, they raised bees.
European colonists brought the honey bee (Apis mellifera) to the Jamestown colony (Virginia) in 1622. The native American Indians called it "the white man's fly." In 1853--231 years later--honey bees reached California. A beekeeper brought the insects here in the middle of the California Gold Rush, 1848-1858. A plaque outside the San Jose Airport heralds their arrival.
In looking through my images of honey bees for this traditional Fourth of July Bug Squad blog, I found two that are especially suitable: Four bees sharing a single blossom.
- Four on a rose
- Four on a pomegranate
May the Fourth Be With You!
If you attended the Lavender Festival last weekend at the six-acre Araceli Farms at 7389 Pitt School Road, Dixon, you were in for a real treat.
Planted in April 2017, the fields glowed with seven varieties of lavender: Grosso, Provence, White Spike, Royal Velvet, Violet Intrigue, Folgate, and Melissa.
This is a family-owned business: parents Robert and Araceli and daughter Justina grow pesticide-free lavender and produce handmade, all natural products. They also host lavender festivals, lavender U-Pick, events, and workshops. (See the family's website and Facebook page.)
Last Saturday the lavender fields buzzed with honey bees from "Clay's Bees," belonging to Clay Ford, who owns the Pleasants Valley Honey Company. He and his wife, Karen, sell their honey at Farmers' Markets in Vacaville and Fairfield and other venues. Soon they'll be adding lavender honey.
But back to the fields: visitors delighted in wreathing lavender around their heads and necks, purchasing lavender products, and photographing one another in the fields. They came with tripods, professional cameras, and cell phones. But most of all, with smiles!
A day in the country with rows and rows of aromatic lavender definitely yields lots of smiles, joy and laughter.
Virtually unnoticed were the insects: Cordovan honey bees, the color of pure gold, rushed to gather the pollen and nectar, as if they knew the fields would be harvested Monday, June 24. We spotted a few yellow-faced bumble bees (Bombus vosnesenskii), cabbage white butterflies (Pieris rapae), and scores of migratory painted ladies (Vanessa cardui). "This is the second post-desert generation (Vanessa cardui), so altogether three generations have been involved," butterfly guru Art Shapiro, UC Davis distinguished professor of evolution and ecology, told us Sunday, June 23. "The flight began here March 17--so today is the 98th day!"
Visitors browsed the vendor booths, all offering products or information. Drawing bee enthusiasts was Tora Rocha of the Pollinator Posse, a Bay Area-based organization that she and Terry Smith founded in Oakland in 2013 to create pollinator-friendly landscaping in urban settings and to foster appreciation of local ecosystems through outreach, education and direct action. Rocha, a retired Oakland parks supervisor, says that eco-friendly landscape techniques are at the heart of their work. They envision a day "when life-enhancing, thought-inspiring green spaces will grace every corner of the city and the world beyond." And spaces filled with bee condos for native bees! They make and sell AirBeeNBees for leafcutter bees and mason bees. (Check out their Facebook page.)
The owners of Araceli Farms love being lavender farmers. "Like anything in life, there wasn't a linear path to this," Justina relates on her blog. "Looking back on it now, I see how I was being prepped for this role, but I had no idea. After college, I landed a highly-sought after job with tons of prestige; it was incredible and I was so excited, but after some time I knew it wasn't my future. It didn't spark passion nor fuel my envisioned."
The lavender farm does.
One of the Araceli Farms employees, Maria Gonzalez of Dixon, sporting a curved harvesting knife, a wide-brimmed hat and an even wider smile, said she's been working the fields for two years.
And lovin' the lavender.
It's easy to love.
(June 17-23 is National Pollinator Week.)
"How many? Does anyone know?"
No one did, but by the end of the Pollination Education Program, sponsored by CAMBP, all 72 youths from the Sutter Creek and Ione area of Amador County did: 20,000.
They also learned that there are 4000 species of bees in the United States, 1600 species in California, and 350 in Yolo County.
And they learned that pollinators include honey bees, bumble bees, butterflies, sweat bees, hummingbirds and syrphid flies.
"Can you all say entomologist?" Mather asked. "Does anyone know what entomology means?"
"Insects," said one youth.
"Yes, entomology is the scientific study of insects," Mather told them. That's what each and everyone of you is today: entomologists! Okay?
She explained the life cycle of a bee: from egg to larva to pupa to adult. "Males are called drones," she said. "Females are called worker bees."
Toward the end of the program, Mather told the students: "You are ready for the university. As soon as you graduate from high school, I hope to see you guys here. You are all excellent, very respectable, responsible and mature scientists. I want you to please take the knowledge that you gathered here today and share it with family and friends."
The Pollinator Education Program (PEP), developed two years ago by CAMPB director and Extension apiculturist Elina Lastro Niño of the UC Davis Department of Entomology and Nematology, along with staff research associate Bernardo Niño, aims to provide a fun, immersive educational experience "to help kids of all ages understand the importance pollinators play in the lives of humans."
At the recent session, Mather shared data on native bees, explained the life cycle of a honey bee, encouraged students to be citizen scientists, and demonstrated how to carefully collect bee specimens with a bee vacuum in a catch-and-release activity.
Volunteer Robin Lowry managed the “Planting for Pollinators” and “Be a Beekeeper” station. Students tried on beekeeping suits and tested the equipment, including a smoker and hive tools.
Volunteer Julia Wentzel introduced the concept of "pollinator specialists" and engaged the students in creating a "pollinator" which they then used to transfer "pollen" to different shaped flowers. Diverse floral sources are integral to honey bee health, she said.
Matthew Hoepfinger, staff research associate in the Niño lab, opened a bee hive (inside a screened tent) and showed the students the queen, workers and drones.
Just before boarding the buses for home, the students sampled several varietals of honey. "This is really good!" a girl said. "I want more."
Ron Antone of the UC Master Gardeners of Amador coordinates the annual program, working with Amador school officials, parents and master gardeners. This year he coordinated two groups:
- Jackson Elementary. 62 third graders, 3 teachers, 2 aides, 3 parents and 2 Master Gardener volunteers from Amador County.
- Ione Elementary. 72 third graders, 3 teachers, 7 parents, 3 Master Gardeners and 3 volunteers from Farms of Amador.
The UC Davis Department of Entomology and Nematology operates the Häagen-Dazs Honey Bee Haven, with Elina Lastro Niño serving as the garden's faculty director and Christine Casey as the manager. Two others from the Niño lab--staff research associate Charley Nye, manager of the Harry H. Laidlaw Jr. Honey Bee Research Facility, and staffer Christine Torres--assisted with the pollinator education programs.
"It takes a village as they say," Mather said.
That it does.

"You can learn a lot from these displays," a fairgoer at the 144th annual Dixon May Fair commented.
She was looking at an educational display with the catchy title, "None of Your Beeswax," the work of Ryan Anenson of the Tremont 4-H Club, Dixon, whose projects include beekeeping. The display is showcased in the Youth Building (Denverton Hall) at the Dixon May Fair, which opened Thursday, May 9 and continues through Sunday, May 12.
In his project, Anenson explained what bees produce. He zeroed in on bee venom, pollen, beeswax, royal jelly, honey, propolis, and also alternative medicine, history of honey, and bee hive air. Anenson concluded: "Honey might be the most well-known bee product in the world, but it certainly isn't the only by-product these magnificent creatures produce. Bees are considered 'the pillars of agriculture' for the work they do in pollination. If you have ever enjoyed most fruit, vegetables and other crops, you should generally thank the bees. Through pollination, bees contribute to maintaining biological balance in nature and help various animal and plant species, including humans, to thrive. Honeybee products are an entirely natural food source and have a long medicinal history that people have used since ancient times.Bees are arguable the most invaluable species to life on earth and are more vital than many people may realize."
As for beeswax, Anenson penned: "Worker bees at a young age will secrete beeswax from a series of glands on their abdomens. They use this beeswax to form the walls and caps of the honeycomb. However, some beekeepers use plastic as a foundation or substitute for honeycomb. Just like the honey that bees produce, many people harvest beeswax for various purposes, like candles, lip balms, creams, polish and conditioners, just to name a few."
The teenage 4-H'er was among those who attended a UC Davis Bee Symposium several years ago, and also participated in a recent California Honey Festival, co-sponsored by the City of Woodland and the UC Davis Honey and Pollination Center.
Madeline Giron, another Dixon 4-H'er, sketched a color pencil drawing of a bee, and Markus Taliaferro of the Suisun Valley 4-H Club, Dixon, submitted a photo of a honey bee sipping nectar. Another drawing, the work of Katelyn Nipper of Fairfield, featured "crayon art flowers": brightly colored spring flowers bordered by the crayons she used.
Lots of flowers! Just add pollinators!
Meanwhile, speaking of pollinators and plants, there's a clearance plant sale at UC Davis on Saturday, May 11 at the UC Davis Arboretum and Public Garden's Teaching Nursery on Garrod Drive. It's open to the public from 9 a.m. to 1 p.m. Horticulturists are billing it as a "Pollinator Paradise." Everything is 15 percent off (Members receive an additional 10 percent off.) You can access the inventory here.
Lots of plants! Just add pollinators!
