Welcome to the Organic Materials Management Blog! This is a place for sharing science and policy information on finding valuable uses for organic wastes in California. It's a blog so I will be a bit informal here, at least compared to refereed journal articles. I plan to include some descriptions of my projects as they develop, as well as news and technical information. I plan to write about topics as I confront them, or as they occur to me.
Now let's get busy. There is a lot to do.

Yes!
That was the scene at the Vacaville Museum Guild's Annual Children's Party, held Thursday morning, Aug. 8 in the museum courtyard on Buck Avenue.
The event, open to children ages 3 and 9, drew a capacity crowd. One of the highlights was The Honey Bee, with a smile as wide as the Sacramento River.
Inside the smiling bee costume was Dr. George Stock (retired physician), who practiced in the Fairfield/Vacaville area for more more than 30 years. A native Californian, he was born and raised in San Diego.
He lives in Vacaville with his life partner, Debbie, for 40-plus years, and "two dogs that changed our lives." He describes himself as a "Sierra hiker, itinerant gardener and wine aficionado."
And now, a honey bee. "Dr. George" handed out honey sticks donated by "Queen Bee" Amelia Harris of the Z Food Specialty/The Hive, Woodland, retired director of the UC Davis Honey and Pollination Center. He stood near a bee observation hive displayed by beekeeper Ettamarie Peterson of Petaluma, known fondly as "The Queen Bee of Sonoma County." A retired teacher, she is a past president of the Sonoma County Beekeepers' Association and is a longtime beekeeping leader with the Liberty 4-H Club.
"That was fun," Dr. George said. "I think the Mickey Mouse/Disney routine worked well. Don't say much, dance and wave your hands, pat ‘em on the head, hold still for photo ops. Thank you for this opportunity." Vacaville residents Pamela King and Diana McLaughlin co-chaired the event, themed "Fun on the Farm."
The California Master Beekeeper Program, directed by associate professor of Cooperative Extension Elina Niño, based in the UC Davis Department of Entomology and Nematology, loaned the costume to the Vacaville Museum Guild for the day. The Bee has appeared at special events, including the annual California Honey Festival in Woodland.
And now at the Vacaville Museum Guild's Children's Party, where there was a doctor in the house, the courtyard and in the bee costume.

But today we're celebrating International Monarch Caterpillar Day as well, because it's the right thing to do. Now, more than ever, we need ways to help and protect monarchs.
If you have a kitty, every day is International Cat Day. Monarchs? Well, there are:
- National Start-Seeing-Monarchs Day: The first Saturday in May
- Monarch Butterfly Day: May 18
- Monarch Blitz: July 26–Aug. 4, an event to raise awareness and support monarch butterfly conservation
- National Endangered Species Day: Monarch Butterflies: Aug. 3
Our tuxedo cat, Xena the Warrior Princess (2000-2016), sported a butterfly-shaped marking on her leg, and regularly checked out the monarch butterflies that fluttered through out pollinator garden. Once I photographed her looking intently at a monarch butterfly. What are you? What are you doing? Are you okay?
Xena was just curious, just being more princess than warrior.
Felis catus and Danaus plexippus. One purrs. One flutters. One breaks our heart when it crosses the Rainbow Bridge. The other plays a vital role in the ecosystem that we're trying to protect. Monarchs boldly lift our spirits, symbolizing hope, rebirth and transformation.

Monarch butterflies seem to be as scarce as hen's teeth around here.
And since hens have no teeth, that's pretty scarce.
And then it happened.
A late in-star monarch caterpillar appeared on our milkweed in our Vacaville pollinator-predator garden on the very last day of July.
We watched it munch the wilting milkweed leaves in the triple-digit temperature.
For one day.
The next day, Aug. 1, it vanished, never to be seen again. Did it pupate? Did the California scrub jays get it?
The scrub jays nesting in our cherry laurel hedges are prime suspects. They devour everything in the garden, from honey bees, longhorned bees and dragonflies to assorted butterflies, lygus bugs and praying mantises. Happy meals. If they eat a monarch caterpillar, that makes for an unhappy meal, the vomiting kind. It's about the naturally occurring toxins (cardiac glycosides) in the milkweed that the 'cats ingest that serve as predatory protection. That's why scientists say "I bet you'll eat only one."
Just one. The one we were watching?
"Known bird predators include brown thrashers, grackles, robins, cardinals, sparrows, scrub jays and pinyon jays," Wikipedia says, but notes that "Several species of birds have acquired methods that allow them to ingest monarchs without experiencing the ill effects associated with the cardiac glycosides (cardenolides). The black-backed oriole is able to eat the monarch through an exaptation of its feeding behavior that gives it the ability to identify cardenolides by taste and reject them. The black-headed grosbeak, though, has developed an insensitivity to secondary plant poisons that allows it to ingest monarchs without vomiting. As a result, these orioles and grosbeaks periodically have high levels of cardenolides in their bodies, and they are forced to go on periods of reduced monarch consumption. This cycle effectively reduces potential predation of monarchs by 50% and indicates that monarch aposematism has a legitimate purpose. The black-headed grosbeak has also evolved resistance mutations in the molecular target of the heart poisons, the sodium pump. The specific mutations that evolved in one of the grosbeak's four copies of the sodium pump gene are the same as those found in some rodents that have also evolved to resist cardiac glycosides."

Did you know that California has a state insect? It does.
Is it the honey bee? No.
Is it the lady beetle (ladybug)? No.
Bumble bee? No.
It's the California dogface butterfly (Zerene eurydice), an insect found only in California.
The state Legislature designated it as the state insect in 1972. The butterfly is nicknamed "dogface" in reference to the silhouette of what resembles a poodle head on the wings of the male. The female is mostly solid yellow except for a single black spot on its upper wings.
Most people have never seen it in the wild. But if you've visited the Bohart Museum of Entomology at UC Davis, home of a global collection of 8 million insect specimens, you know that its logo is the California dogface butterfly.
And on Thursday, Aug. 8 those attending the Vacaville Museum Guild's Annual Children's Party (sold out) will see specimens from the Bohart Museum, as well as macro images of the butterfly, the work of talented Bohart associate Greg Kareofelas of Davis.
Tabatha Yang, education and outreach coordinator of the Bohart, has donated a drawer of the specimens for visitors to see. They can also pose in a cutout of the Bohart Museum's California dogface butterfly banner. And thumb through a 35-page children's book, "The Story of the Dogface Butterfly," written by UC Davis doctoral alumna Fran Keller, a professor at Folsom Lake College and a Bohart Museum research scientist. The book includes images by Kareofelas and Keller. Laine Bauer, then a UC Davis student, contributed the illustrations.
The book, published in 2013, tells the untold story of the California dogface butterfly, and how schoolchildren became involved in convincing the State Legislature to select the colorful butterfly as the state insect. Fourth grade students of Betty Harding and Shirley Klein, Dailey Elementary School, Fresno, advocated it as the state insect. The teachers and students enlisted the help of State Assemblyman Kenneth L. Maddy, who authored AB 1834. On July 28, 1972, Governor Ronald Reagan signed the bill into law, designating the California dogface butterfly the official "State Insect of California." (Read more on how the butterfly became the state insect under the Ronald Reagan administration.)
The most prevalent habitat of the California dogface butterfly is the 40-acre Shutamul Bear River Preserve near Auburn, on a Placer Land Trust conservation site; Kareofelas serves as a docent on the Placer Land Trust tours. (See virtual tour on YouTube). The butterfly is there because its larval host plant, false indigo (Amorpha californica), is there.
Are there dogface butterflies in Vacaville? Yes. The butterfly's breeding grounds include Gates Canyon. (See UC Davis emeritus professor Art Shapiro's website.)
As mentioned, few people see the butterfly in the wild. However, its image graces a first-class U.S. stamp and California driver licenses. It's also depicted on the California State Fair monorail.
Butterfly Poster and Book. The Vacaville Museum Guild's Children's Party (see what's on tap) also will spotlight a Bohart Museum poster by Kareofelas-Keller that depicts the male and female butterfly. (Both the poster and the book are available for sale in the Bohart gift shop; net proceeds benefit the insect museum's education, outreach and research programs.)
The Bohart Museum, located in Room 1124 of the Academic Surge Building, 455 Crocker Lane, also houses a petting zoo (featuring stick insects, Madagascar hissing cockroaches and tarantulas) and a insect-themed gift shop, stocked with books, posters, t-shirts, hoodies, jewelry and collecting equipment. Director of the insect museum is Professor Jason Bond, the Evert and Marion Schlinger Endowed Chair, UC Davis Department of Entomology and Nematology, and associate dean, Agricultural Sciences, UC Davis College of Agricultural and Environmental Sciences.
The Bohart is open for walk-in visitors on Tuesdays from 9 a.m. to noon and from 1 to 4:30 p.m. through Aug. 27. It will be closed to the public Sept. 1-22.
The next open house is set for 1 to 4 p.m., Saturday, Sept. 28. The theme is "Museum ABC's: Arthropods, Bohart and Collecting." All open houses are free and family friendly. Parking is also free. For more information, contact bmuseum@ucdavis.edu or access the website at https://bohart.ucdavis.edu.
