Scientists, conservationists and citizen scientists were there to discuss "Recovering the Western Monarch Butterfly Population: Identifying Opportunities for Scaling Monarch Habitat in California's Central Valley."
"The western population of the monarch butterfly has garnered widespread attention because of its dramatic decline in recent decades," the Environmental Defense Fund said in its opening statements. "The latest population surveys indicate that monarchs overwintering on the central coast have declined 86% since last winter and now total 0.5% of their historical average. Population declines have spurred greater scientific study, funding, and coordination around the western monarch. California legislators appropriated $3 million in funding to the California Wildlife Conservation Board to establish the Monarch Butterfly and Pollinator Rescue Program."
In his presentation, Shapiro told the group: "As of right now, the monarch is on life support in California, and we are reduced to prescribing placebos. If our patient comes back from the brink—as history suggests it may well—will we convince ourselves that our placebos worked? Probably. And that's not how to do science. That's what philosophers call the fallacy of post hoc, ergo propter hoc." (See Shapiro's other comments)
Shapiro, who has monitored the butterfly populations of central California for more than four decades, posts his research on his website, Art's Butterfly World.
Meanwhile, the widespread interest in monarchs continues to widen. What's happening with the monarchs this year?

Where are you, Gulf Fritillaries?
The Gulf Fritillary (Agraulis vanillae) population seems to be diminishing this year around Solano and Yolo counties.
A few here, a few there, but not in the large numbers of last year.
Last summer the Gulf Frits overwhelmed our passionflower vine (Passiflora), their host plant, and skeletonized it.
Which is what we want them to do. We plant Passiflora for them, not for the fruit or the blossoms. On a good year, they eat it all--blossoms, fruit, leaves and stems--and look for more.
The history of the butterfly in California is as striking as its silver-spangled, reddish-orange coloring.
“It first appeared in California in the vicinity of San Diego in the 1870s,” says noted butterfly expert Art Shapiro, distinguished professor of evolution and ecology at the University of California, Davis. “It spread through Southern California in urban settings and was first recorded in the Bay Area about 1908. It became a persistent breeding resident in the East and South Bay in the 1950s and has been there since.”
Shapiro, who has monitored butterflies in central California since 1972 and maintains a research website at http://butterfly.ucdavis.edu, says the Gulf Frit “apparently bred in the Sacramento area and possibly in Davis in the 1960s, becoming extinct in the early 1970s, then recolonizing again throughout the area since 2000.”
It's making a comeback, but this year it doesn't seem to be "coming back" so much.
Want to attract the Gulf Frit? Plant its host plant and some of its favorite nectar plants. In our pollinator garden in Vacaville, their favorite nectar sources include the butterfly bush (Buddleia), Mexican sunflower (Tithonia) and lantana (genus Lantana.)
Plant them and they will come--if they're around!
Honey bees own the flower beds at the Solano County Fair, 900 Fairgrounds Drive, Vallejo.
But bees and other insects claim the exhibit halls, as well. They're depicted on everything from quilts and photos to graphic arts displayed in McCormack Hall.
Indeed, pollinators are an integral part of the exhibits at the 70th annual Solano County Fair, which opens Thursday, June 27 and continues through Sunday, June 30. The annual family-based fair aims to inform, educate and entertain.
Gloria Gonzalez, superintendent of McCormack Hall, and a community leader with the Sherwood Forest 4-H Club, Vallejo, called attention to the colorful bees framing a 9-patch maple leaf quilt showcased in the adult division. It is the work of Tina Frothy of Vallejo.
And some of the youth entries?
- Jessie Means of the Pleasants Valley 4-H Club, Vacaville, entered a close-up photo of a honey bee.
- Maya Prunty of the Pleasants Valley 4-H Club submitted a photo of a caterpillar.
- Alana Boman of the Sherwood Forest 4-H Club sketched a moth.
- Madeline Giron of Benicia drew a bee.
Butterfly guru Art Shapiro, UC Davis distinguished professor of evolution and ecology, identified it as Parthenos sylvia ssp. lilacinus from Southeast Asia. "Its English name," he said, "is the Blue Clipper."
Locally, you can see Blue Clipper specimens in the Bohart Museum of Entomology in Room 1124 of the Academic Surge Building on Crocker Lane, UC Davis. "We have 11 specimens of this subspecies and specimens of 4 other subspecies of Parthenos sylvia, as well as specimens of two other species in the genus," said entomologist Jeff Smith, curator of Lepidoptera at the Bohart. He describes the butterfly as "beautiful with a strong wingbeat." Smith remembers collecting one in Thailand when he was serving with the U.S. Air Force.
Gonzalez said some of the items entered in the fair are tagged for the silent auction; the highest bidder takes the entry home.
Admission to the Solano County Fair is free all four days. Parking is free the first day only. Gates are from 6 p.m. to 9 p.m. on Thursday, and from noon to 8 p.m., Friday through Sunday. See more information on the website.
Cheers to 70 years! And cheers to the exhibitors who picked pollinators!
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.
If you visit the Kate Frey Pollinator Garden at Sonoma Cornerstone--and you should, especially during National Pollinator Week--you'll see honey bees, bumble bees, butterflies and hummingbirds, among other pollinators.
Today we spotted a male monarch patrolling the milkweed in search of a female, and a Western tiger swallowtail nectaring alternately on Verbena and on Salvia 'indigo spires.'
About that Western tiger swallowtail--it was missing a chunk of its left forewing. A predator--maybe a bird or a praying mantis--tried to nail it but missed.
About that garden--it's the work of Kate Frey, a world-class pollinator garden designer, pollinator advocate and author. When she addressed the 2018 UC Davis Bee Symposium on "Designing Bee Friendly Gardens," she said that "Bee gardens make us happy."
They do indeed.
Frey, a resident of Hopland, co-authored the award-winning book, The Bee Friendly Garden, with Professor Gretchen LeBuhn of San Francisco State University. It's a book that details how to design an abundant, flower-filled garden that nurtures bees and supports biodiversity.
And make us happy.
About that butterfly--the Western tiger swallowtail, Papilio rutulus, is common throughout western North America and is often seen in urban parks and gardens. In color, it's a striking yellow and black, with spots of blue and orange near its tail. Its wingspan can measure 3 to 4 inches.
It's "basically a species of riparian forest, where it glides majestically back and forth along the watercourse," says butterfly guru Art Shapiro, UC Davis distinguished professor of evolution and ecology on his website."It has expanded into older urban neighborhoods where several of its host genera are grown as shade trees, and behaves as if the street were a watercourse."
When we left Sonoma Cornerstone today, the "tiger" was still floating, fluttering and flittering, quite majestically, too, throughout the garden, despite the wear and tear on its left forewing.
Survival of the flittest...
