From the UC Blogosphere...
We all take shortcuts.
We look for the shortest line at the supermarket, we use keyboard shortcuts, and we text ”how r u?”
So, why shouldn't honey bees use shortcuts? They do.
If you've ever watched a carpenter bee drill a hole in the corolla of a tubed flower to get at the nectar—this is "nectar robbing" or bypassing pollination—you may have seen a honey bee come along and sip nectar from the hole. Why work hard to get at the nectar when it's right there for the taking?
This is the insect version of a convenience market!
Take the foxgloves (family Plantaginaceae, genus Digitalis). Sometimes you'll see a honey bee trailing or shadowing a carpenter bee that moves from corolla to corolla.
Short cut to the nectar!

When a monarch butterfly comes fluttering through your yard, grab your camera. Marvel at it beauty, celebrate its presence, and keep it in your memory. It may be become an endangered species the way things are going.
The Xerces Society for Invertebrate Conservation recently reported that the monarch population has declined by more than 90 percent in under 20 years. And, “during the same period it is estimated that these once-common iconic orange and black butterflies may have lost more than 165 million acres of habitat — an area about the size of Texas — including nearly a third of their summer breeding grounds.”
So a trio—Center for Biological Diversity, Center for Food Safety, and the Xerces Society—filed a legal petition asking the U.S. Fish and Wildlife Service for Endangered Species status to protect the monarch (Danaus plexippus).
The widespread loss of milkweed, the butterfly's host plant, especially throughout the Midwest, is troubling.
Butterfly expert Art Shapiro, distinguished professor of evolution and ecology at the University of California, Davis, says there's plenty of milkweek in Northern California. “The problem is that nobody's there to breed on it.” For example, he sees large spreads of milkweed (Asclepias speciosa) around his many monitoring sites, including one by the Vacaville (Calif.) Transit Center. “Probably 75 stems, but I have never ever seen a monarch there, let alone any evidence of breeding." (See his entry on monarchs on his website.)
So, a monarch's solo visit to our little bee garden seems like a major event. When we see one, as we did Sept. 17, it heads straight for the Mexican sunflower (Tithonia).
Backlit, the monarch resembles a stained glass window. What a gorgeous butterfly, worthy of the royal name, “monarch!”
The only question is: will we consider it worthy enough to save it?
- Plant milkweed, its host plant.
- Avoid insecticides or herbicides.
- Become a citizen scientist and help record sightings.
- Support conservation efforts.
- Promote public awareness.

Art Shapiro, distinguished professor of evolution and ecology at UC Davis, isn't feeling so well--to put it mildly--but he still went out on one of his butterfly monitoring expeditions today at his study site in North Sacramento.
He recorded 12 species of butterflies in the dry vegetation. (He's been monitoring the butterfly population in Central California for some four decades and he shares the information on his website.)
Frankly, we're surprised he went monitoring at all, especially after he emailed friends and colleagues about the bad news. Subject line: "Breaking Bad."
"At 4:30 p.m. on Thursday, Sept.11, my world turned upside-down. So did I.
"I was just into the crosswalk from the NW corner of Oak and Russell in Davis, heading south toward my lab, when I was struck from behind with great force by a bicyclist. I flew through the air and landed on the pavement head-first, with the right side of my face bearing the worst of the impact. The wife of a departmental colleague arrived on the scene a moment later; I believe she called 911. I was never unconscious, which is strange. My neck could easily have been broken, resulting in either death or paralysis, but it wasn't (the EMTs had assumed it was!). I was rushed to Sutter Davis Hospital and thence transferred to the UC Davis hospital trauma unit in Sacramento....Every bone on the right side of my face was pulverized. I had no more eye socket (orbit) and no more right cheekbone."
It was not a hit-and-run, as some folks speculated. The bicyclist stayed for the police report.
Through it all, Shapiro retained his sense of humor and is now back at work in his Storer Hall office after surgery on Sept. 12 and a repeat visit to the UC Davis Medical Center today. And he can see again.
"...my right eye is swollen shut, I am all black and blue and look like I've been in the ring with Mike Tyson. I look like a ghoul in a zombie-apocalypse movie, with caked blood, blah blah. I'm not sure I've ever felt worse, though, oddly, there hasn't been all that much pain."
So, immediately after the Medical Center appointment, he trekked over to his North Sacramento study site. His appearance did not go unnoticed. "Looking like I do is an invitation for street people, homeless, and down-and-outers to talk to you, as I learned today. There were only two campers at North Sac, but I had a dozen such conversations...most of them assumed I had been in a fight." One guy said said 'I hope you gave the other guy as bad as you got!'
True to form, Shapiro appeared to be most interested in monitoring butterflies than monitoring his physical condition.
"North Sac: 88F, clear, very light S wind. No new fires. Veg very dry, less of everything in bloom except Euthamia (goldentops) Hemizonia (tarweeds), and Epilobium (willowherbs/fireweeds) all peaking. No coyote brush (Baccharis pilularis) yet. With all the Euthamia I expected (Atlides) halesus (Great purple streak), but didn't see it; with all the Epilobium expected (Ochlodes) sylvanoides (Woodland skipper), but didn't see it, either; and there were no Poanes melane (umber skipper)."
The species he recorded:
- Junonia coenia, 11, Buckeye
- Pyrgus communis, 18, Common Checkered Skipper
- Plebejus acmon, 5, Acmon Blue
- Pieris rapae, 19, Cabbage White
- Strymon melinus, 4, Gray Hairstr.eak
- Brephidium exile, 1. Western Pygmy Blue
- Atalopedes campestris, 4, Field Skipper
- Phyciodes mylitta, 10, Mylitta Crescent
- Everes comyntas, 1, Eastern Tailed Blue
- Hylephila phyleus, 7, Fiery Skipper
- Limenitis lorquini, 3, Lorquin's Admiral
- Agraulis vanillae, 1, Gulf Fritillary
Twelve different species. Eighty-bugs.
And what did Shapiro have to say about his field trip? "Me and AH-nold: we're b-a-a-a-a-a-c-k."
"It feels good," he added.
And we're all feeling good--whew!--that he's feeling good.
That was a close one.

UC Master Gardener programs in Riverside, Santa Clara, Orange and San Diego counties have won the program's Search for Excellence competition, announced Missy Gable, director of UC's statewide Master Gardener Program. The triennial Search for Excellence awards afford county programs the opportunity to share successful projects, including demonstration gardens, workshops, presentation or hands-on programs, community service, horticulture therapy, research or youth programs.
Educating the public was the focus of the Search for Excellence 2014 competition. The entries were judged by a team of experts selected from throughout the state.
"Congratulations to all the Master Gardeners involved in carrying out these innovative projects," Gable said. "This competition celebrates the hard work of dedicated UCCE Master Gardener volunteers across the state."
The Search for Excellence competition winners will be honored at the 2014 UC Master Gardener Conference, Oct. 7-10 in Fish Camp, Calif. The next Search for Excellence competition will be in 2017.
“There's Gold in them thar hills!” Riverside County is a big county, stretching from the Los Angeles metro area to the Colorado River. The main challenge of the UC Master Gardener Program of Riverside County was how to better fulfill their mission of educating their community on sustainable gardening practices. The answer – “Gold Miners.” Riverside County was divided into nine geographic areas with a UC Master Gardener volunteer in each area actively pursuing volunteering opportunities for their peers. Since the program began in 2011, “Gold Miners” has increased the presence of UC Master Gardeners throughout the county, giving volunteers the opportunity to provide outreach closer to home, engage new members of the public and increase the number of certified UC Master Gardeners from all regions of the county.
UC Master Gardeners of Santa Clara County developed a one-acre teaching and demonstration garden on the grounds of St. Louise Hospital in Gilroy. The demonstration garden was designed to create educational outreach opportunities in the far southern portion of the county. UC Master Gardener volunteers provide hands-on public workshops in the garden as well as classes in both the hospital boardroom and community libraries. The objectives of the St. Louise Hospital garden includes teaching residents about low-water vegetables, fruits, and ornamental plants well-suited to local growing conditions, and modeling sustainable gardening practices reflective of UC research-based horticultural principles.
Passionate volunteers from the UC Master Gardener Program of Orange County developed a series of 15 educational videos. Nine videos provide a comprehensive overview of the composting process and six videos concentrate on worm composting. Each series begins with an explanation of what composting is and shifts into how to start, maintain and troubleshoot a compost pile or worm bin. The videos are designed to instruct and encourage the gardening public to compost either at home or in community gardens. All of the educational videos were filmed and narrated by UC Master Gardeners. The videos are published on the UC Master Gardeners of Orange County public website.
First Runner-up - Orange County
Recognizing the need to reach a significantly larger number of home gardeners than demonstration booths and Farmers Market tables were engaging, the UC Master Gardeners of Orange County developed a speakers bureau. The criteria was simple: fulfill the mission of disseminating up-to-date, research-based information and to deliver "wow" presentations for the public. UC Master Gardeners created teaching plans, incorporating the statewide program mission and the ANR Strategic Vision to cover important topics such as gardening for improved nutrition and healthy living. Additionally, the UCCE Master Gardeners of Orange County engaged the help of Toastmasters International, an undisputed authority for training speakers.
Second Runner-up - San Diego County
UC Master Gardeners of San Diego County created a program called MG Growing Opportunities (MG-GO) which provides research-based horticulture education to teenage youth involved with the juvenile justice system. Under the guidance of UC Master Gardeners and a vocational horticultural therapist, incarcerated youth learn about ecosystem friendly, sustainable gardening. In the process, the youth acquire vocational and life skills, such as teamwork, problem solving, self-esteem, and leadership. The goals of MG-GO are to introduce sustainable gardening practices to an under-served population, highlight gardening as a healing endeavor, and develop a replicable model for statewide use.
The UC Master Gardener Program provides the public with UC research-based information about home horticulture, sustainable landscaping, and pest management practices. It is administered by local UCCE county-based offices that are the principal outreach and public service arms of the University of California Division of Agriculture and Natural Resources.
The UC Master Gardener Program is an example of an effective partnership between the UC Division and passionate volunteers. In exchange for training from University of California, UCCE Master Gardener volunteers engage the public with timely gardening-related trainings and workshops. With programs based in 50 California counties and 6,048 active members, UC Master Gardener volunteers donated 385,260 hours last year and have donated more than 4.2 million hours since the program inception in 1981.
The Pollinator Partnership, as part of its U.S. Bee Buffer Project, wants to partner with California farmers, ranchers, foresters, and managers and owners to participate in a honey bee forage habitat enhancement effort. It's called the U.S. Bee Buffer Project and the goal is to "borrow" 6000 acres to plant honey bee seed mix.
It will create a foraging habitat of pollen and nectar, essential to honey bee health. And there's no charge for the seed mix.
What a great project to help the beleaguered honey bees!
"Beekeepers struggle to find foraging areas to feed their bees when they are not in a pollination contract," said "idea generator" Kathy Kellison of Santa Rosa, Sonoma County, a strong advocate of keeping bees healthy. "Lack of foraging habitat puts stress on the bees and cropping systems honey bees pollinate. The U.S. Bee Buffer Project will develop a network of honey bee forage habitats in agricultural areas to support honey bee health and our own food systems. We are looking for cooperators with land they are willing to set aside as Bee Buffers."
Kellison points out:
- Honey bees provide pollination services for 90 crops nationwide.
- A leading cause for over-winter mortality of honey bee colonies given by beekeepers surveyed is starvation. The nationwide winter loss for 2012/2013 was 31.3 percent.
The requirements, she said, are minimal:
- Access to an active farm, ranch, forest, easement, set-aside, or landscape
- Ability to plant 0.25 to 3 acres with the U.S. Bee Buffer seed mix
- Commitment to keep the Bee Buffer in place
- Allow beekeepers and researchers on-site
Of course, the benefits to the participants include free seeds and planting information; supplemental pollination of flowering plants; and leadership participation in the beginnings of a nationwide effort to support honey bees. Then there's the potential for enriched soil, reduction in invasive plant species, and enhanced wildlife habitat.
And, we made add, a sense of accomplishment as bees forage on your thriving plants.
Those interested in participating in this nationwide effort and hosting a Bee Buffer, can visit http://www.pollinator.org/beebuffer.htm to fill out a brief eligibility questionnaire.
