Last Dec. 27 at the Natural Bridges State Park, we saw dozens of monarchs about 80 feet up in the eucalyptus trees. When the sun broke through the trees, assorted birds targeted them, scattering them like mosaic paper kites, much to the awe and aahs of the crowd below.
"Monarch butterflies are among the largest members of the family Nymphalidae in North America. Their caterpillars store toxic chemicals called cardiac glycosides in their bodies from the milkweed they eat. Cardiac glycosides make vertebrates like us quite sick, so don't eat a monarch butterfly or caterpillar if you can help it. The chemicals remain in the adult butterfly bodies as well but tend to be concentrated more in the wings than in the body. Interestingly, cardiac glycosides seem to have very little effect on insect predators and parasites."
"The annual North American migration begins as early as August. Populations west of the Rockies migrate to the Pacific Coast with overwintering roosts along the central California coast. One of the best known of these is in Pacific Grove, California. Populations east of the Rockies migrate to central Mexico. Adult monarchs typically only live a couple of months, although they can live up to 5 or 6 months so the individuals that emerge in early summer do not migrate. Each generation takes between 5 and 6 weeks from egg to adult. The last generation of the summer goes into migratory mode. They stop reproducing and fly in a linear fashion to one of the overwintering sites. These individuals generally do not begin reproducing until the following spring in February or March when they leave these sites and move north from the Mexican site or north and east from the Pacific Coast."
Welcome back, monarchs! You're now fueling up for mass migration.

And when you do, you'll be helping the bees, butterflies, beetles and bats.
In June, the National Pollinator Garden Network launched the Million Pollinator Garden Challenge, hoping to register one million pollinator gardens throughout the country within a two-year period.
The gardens? They can be public or private gardens or landscapes that support pollinators. If you don't have access to a garden, you can fill pots with pollinator plants and grace your deck, patio, balcony or windowsill.
The Porland, Oregon-based Xerces Society for Invertebrate Conservation, an international nonprofit organization that protects wildlife through the conservation of invertebrates and their habitat, is a partner. Communications director Matthew Shepherd wrote a blog last June challenging us all to help the pollinators. The Garden Network, coordinated by the National Wildlife Federation, is an outgrowth of the White House's National Pollinator Strategy. "It draws together nearly two dozen nonprofits and organizations with a shared aim, to make gardens better for pollinators nationwide," Shepherd says.
Your garden should offer a diversity of plants rich in nectar and pollen. No pesticides. That bears repeating. No pesticides. And don't mulch your entire garden; leave some bare soil for solitary bees to nest. And it's good to install bee condos for leafcutter bees and blue orchard bees.
You can register your garden on the SHARE website where "visitors will be able to visually track the progress of the campaign," according to the Million Pollinator Garden Challenge. "Registrants can upload photos and videos of their sites, and the map can be sorted by garden type. In addition, a metric to assess pollinator garden actions across multiple organizations will be in effect as the campaign progresses."

"The front is sunny, the back a shady forest edge—part of the reason for the diversity of plants," Shepherd noted.
In our bee/butterfly garden in Vacaville, Calif., we've planted milkweeds (host plant of the Monarchs), passionflower vine (host plant of the Gulf Fritillaries), English lavender, salvias, blue beard, catmint, lantana, Mexican sunflowers (Tithonia), Photinia, butterfly bushes, honeysuckle, blanket flower, California poppies, alyssum, gaura, California fuchsia, crape myrtle, African blue basil, cherry laurels, foxgloves, sedum, dwarf bulbine, oregano, rock purslane, cosmos, zinnias, tomatoes, cucumbers, pomegranates, olives, lemons and tangerines, to name a few.
We're feeding the bees, butterflies and beetles. And other pollinators, such as hummingbirds and moths. We're not feeding the praying mantids. They're feeding themselves.

Standing on her front porch last Wednesday morning, overlooking the Dutchman's pipevine that her mother Della planted in the 1920s, Louise Hallberg is a picture of enthusiasm, dedication and sincerity--or what her docents call her “indomitable spirit.”
Her butterfly sanctuary, a non-profit corporation since 1997, has drawn more than 30,000 visitors, including scores of wide-eyed children and their teachers and parents butterfly enthusiasts, gardeners, and nature lovers. “Over 1000 visitors came on our Open Gardens Day on June 28,” she says. Many visitors come from out of the county, the state, and the country, she said.
Her expression turns to concern. I"'m terribly concerned about the drought. We've very low on rainfall. It was 105 on Sunday. It's been so hot, so long.” She is deeply concerned about the decline of butterflies. “I've tracked the butterflies here since 1992,” she relates. “We're not getting the numbers we used to.”
Louise Hallberg, who will be 99 next January, was born on the family farm. Her grandparents, John and Louise Neta Pearson, initially purchased 40 acres and expanded it to 130 acres, growing hops, berries, cherries, prunes, pears and apples. The oldest of their three children, Alfred, later took over the farm, and he and Della--the one who planted that Dutchman's pipe---raised two daughters, Louise and Esther.
“I remember when my mother found the Dutchman's pipevine growing along a country road and brought it here and planted it,” Louise recalls. “Look at it now."
Louise studied at Santa Rosa Junior College and UC Berkeley, majoring in political science. Then she worked 35 years as Santa Rosa Junior College registrar, retiring in 1975.
But it was the pipevine swallowtails that continued to spark her interest and what led to the formation of the butterfly sanctuary. She monitors the populations of many species of butterflies, keeping careful records. The numbers keep dwindling but not her passion.
On our visit, we enjoyed the ponds, the vivarium, the “secret garden,” butterfly creek, pipevine theater, the woodpecker granary, the meadow garden, and the weather station that her family has monitored and maintained for more than three decades. .We glimpsed the Gravenstein apple orchard and ladders leaning up against the trees, a scene from yesteryear that never changes.
"We add new plants (funded by donations) every year," Hallberg says. The Hallberg Butterfly Gardens, in western Sonoma County, are open by appointment for docent-guided tours from April 1 to Oct. 31. Appointments are offered Wednesday through Sunday, between 10 a.m. and 4 p.m. (Contact the tour and volunteer coordinator (707) 591-6967 or email her at leah@hallbergbutterflygardens.org to arrange a visit.) The non-profit corporation offers books, posters, t-shirts and other gifts. It annually hosts an Open Gardens Day in June that includes a plant sale. Louise Hallberg continues to publish her newsletter, aptly named "The Pipevine."
Meanwhile, during our visit, the red-spotted pipevine swallowtail caterpillars went about munching the leaves of the Dutchman's pipevine, while butterflies laid their eggs on their host plants: the monarchs on the milkweed and the anise swallowtails on fennel.
We thought back to the conversation on the front porch with this remarkable 98-year-old "Butterfly Lady of Sebastopol" and her love of the swallowtails, monarchs and dozens of other species of butterflies--and the worries she harbors, not for herself, but for the butterflies.
"It's been so hot, so long."

Beetles do it. Birds do it.
Bats do it.
Do what, you ask? They pollinate!
The Bohart Museum of Entomology at the University of California, Davis, will greet visitors on Saturday, March 14 at its open house, themed "Pollinator Nation."
To be held from 1 to 4 p.m. in Room 1124 of the Academic Surge Building on Crocker Lane, it promises to be both fun and educational.
“It will be about bees, bees, bees!” said Lynn Kimsey, director of the Bohart Museum and professor of entomology at UC Davis. "Also, we are borrowing specimens of pollinating birds, bats and lemurs from the UC Davis Museum of Wildlife and Fish Biology to cover non-insect pollinators, which should be fun."
Lots of animals are pollinators. It's not just bees, bats, butterflies. bats and birds. Pollinators can be ants, flies, moths, wasps and the like.
You'll see many of them at the open house. Staff research associate Billy Synk of the Harry H. Laidlaw Jr. Honey Bee Research Facility, will provide a bee observation hive. That's a glassed-in hive filled with a bee colony. You'll be able to see the queen bee, worker bees and drones.
The event is free and open to the public. Family activities are also planned.
Special attractions include a “live” petting zoo, featuring Madagascar hissing cockroaches, walking sticks and tarantulas
The Bohart Museum houses a global collection of nearly eight million specimens. It is also the home of the seventh largest insect collection in North America, and the California Insect Survey, a storehouse of the insect biodiversity. Noted entomologist Richard M. Bohart (1913-2007) founded the museum.
The museum is open to the public four days a week, Monday through Thursday, but special weekend open houses are held throughout the academic year
The Bohart Museum's regular hours are from 9 a.m. to noon and 1 to 5 p.m. Mondays through Thursdays. The insect museum is closed to the public on Fridays and on major holidays. Admission is free.
More information is available by accessing the website at http://bohart.ucdavis.edu/; telephoning (530) 752-9493; or emailing bmuseum@ucdavis.edu.

Butterflies draw smiles instead of scowls, pleasure instead of pain, glee instead of grief.
So, here's Part 1 of the good news. You still have a chance to win the Beer-for-a-Butterfly contest. No one has come forth in the three-county area of Sacramento, Yolo and Solano to deliver the first cabbage white butterfly of the new year to Art Shapiro, distinguished professor of evolution and ecology at the University of California, Davis. If you collect the first one of 2015 and you're the verified winner, you'll receive a pitcher of beer or its equivalent.
Shapiro, who usually wins his own Beer-for-a-Butterfly contest, hasn't found one either. Every day has amounted to a "No Fly Day" and a "No Beer Day."
Reports are surfacing that the cabbage whites (Pieris rapae) are flying in Santa Rosa, but unfortunately (or fortunately, depending on your perspective), Santa Rosa is in Sonoma County, not in Sacramento, Yolo or Solano counties.
Shapiro has sponsored the annual contest since 1972. It's all part of his four-decade study of climate and butterfly seasonality. “It is typically one of the first butterflies to emerge in late winter. Since 1972, the first flight has varied from Jan. 1 to Feb. 22, averaging about Jan. 20." Shapiro says his long-term studies of butterfly life cycles and climate "are especially important to help us understand biological responses to climate change. The cabbage white is now emerging a week or so earlier on average than it did 30 years ago here."
Shapiro, who is in the field more than 200 days a year, knows where and when to look. In fact, he's been defeated only three times since 1972, and all by his graduate students. Adam Porter defeated him in 1983; and Sherri Graves and Rick VanBuskirk each won in the late 1990s.
In 2014, Shapiro netted the winning butterfly at 12:20 p.m. Tuesday, Jan. 14 in West Sacramento, Yolo County. It ranked as "the fifth or sixth earliest since 1972.
The contest rules include:
- It must be an adult (no caterpillars or pupae) and be captured outdoors.
- It must be brought in alive to the department office, 2320 Storer Hall, UC Davis, during work hours, 8 a.m. to 5 p.m., Monday through Friday, with the full data (exact time, date and location of the capture) and your name, address, phone number and/or e-mail. The receptionist will certify that it is alive and refrigerate it. (If you collect it on a weekend or holiday, keep it in a refrigerator; do not freeze. A few days in the fridge will not harm it.)
- Shapiro is the sole judge.
Part 2 of the good news about butterflies: a mid-winter gathering of Northern California Lepidopterists and the Bohart Museum of Entomology will take place at an open house from 10 a.m. to 4 p.m., Saturday, Jan. 31 in the Bohart Museum, located in Room 1124 of the Academic Surge Building, Crocker Lane, UC Davis campus. Hosts are Bohart senior museum scientist-entomologist Steve Heydon and entomologists John De Benedictis and Jeff Smith.
Lepidopterists are researchers or hobbyists who specialize in the study of butterflies and moths in the order Lepitopdera.
All interested persons are encouraged to bring specimens, photos, PowerPoint presentations or slides from collecting trips and tales of collecting triumphs to share with others. Butterfly t-shirts and other entomological merchandise are available from the gift shop.
The museum, directed by Lynn Kimsey, professor of entomology at UC Davis, houses a global collection of nearly eight million specimens, and is also the home of the seventh largest insect collection in North America, and the California Insect Survey, a storehouse of the insect biodiversity. It was founded by noted entomologist Richard M. Bohart (1913-2007).
For more information on the mid-winter gathering of lepitopterists, contact Steve Heydon at (530) 752-0493 or slheydon@ucdavis.edu.
Meanwhile, The Great White Cabbage Butterfly Hunt is still underway. Can you find one before Art Shapiro does?
