How about "getting the red in?"
Have you ever seen a honey bee packing white, pink, blue, lavender, yellow, orange or red pollen? Have you ever seen the colorful diversity of pollen grains gracing their hives? Stunning.
Take red. It's a warning color in nature--think lady beetles, aka ladybugs. Predators know they don't taste good so they learn to leave them alone.
A chunk of red pollen on a honey bee, however, looks like a sun-ripened strawberry.
Lately we've been seeing honey bees with red pollen foraging on our Spanish lavender, Lavandula stoechas. Problem is, lavender yields a pale whitish pollen, not red. Last summer, the red came from the adjacent rock purslane (Calandrinia grandiflora). It's not blooming now, however, so, they're drawing that brilliant red pollen elsewhere. And stopping by the Spanish lavender for nectar, their flight fuel.
Robbin Thorp, distinguished emeritus professor of entomology at UC Davis, says "I have not observed honey bees collecting pollen from lavender, but have seen them with pollen loads from other flowers stopping for a sip of nectar...especially honey bees that have been foraging on plants that do not produce nectar like California poppies, and lupines."
"English lavender, rosemary, thyme, oregano, and most other members of the mint family have pale pollen rarely collected by honey bees, but these garden herbs are all great nectar resources," he says. "It is common to see honey bees on these plants with the wrong color pollen as they forage the herbs for nectar."
We're waiting for the cilantro to bloom. Then the bees will "be in the pink," so to speak. Pink pollen.
Meanwhile, if you want to learn more about honey bees, three UC Davis-affiliated events await you.
Saturday, May 6: The inaugural California Honey Festival, an event coordinated by the UC Davis Honey and Pollination Center, will be held within a four-block area in downtown Woodland. Free and open to the public, it will include presentations, music, mead speakeasies, honey-tasting, vendors, bee friendly gardening, and a kids' zone.
Sunday, May 7: The third annual UC Davis Bee Symposium, sponsored by the Honey and Pollination Center and the UC Davis Department of Entomology and Nematology, will take place in the UC Davis Conference Center. Keynote speaker is Steve Sheppard, professor and chair of the Department of Entomology, Washington State University, Pullman, Wash. Registration is underway.
Tuesday through Friday, Sept. 5-8: The Western Apicultural Society, founded at UC Davis, will return to UC Davis for its 40th annual meeting. It was co-founded by Norm Gary (it was his brainchild), Eric Mussen and Becky Westerdahl at what is now the Harry H. Laidlaw Jr. Honey Bee Research Facility, UC Davis. Mussen, now Extension apiculturist emeritus, is serving his sixth term as president since 1984. WAS serves the educational needs of beekeepers from 13 states, plus parts of Canada.

If you like writing with light (photography), then you'll probably love capturing images of honey bees spinning like helicopters.
In the late afternoon, when the light softens, head over to your favorite Spanish lavender patch. Pull up a chair, listen to the buzz of the bees, and watch them spin their wings somewhat like helicopters do their blades.
Such was the case yesterday. The bees were buzzing so loud in the patch of lavender, Lavandula stoechas, that they sounded like spring unleashed. That buzz you hear is their wings; they've been recorded at 200 beats per second. Honey bees can be long-distance travelers; they can forage up to five or six miles, and can move about 15 miles per hour.
Those streaming purple petals topping the bloom are actually sterile bracts--Wikipedia defines a bract as "a modified or specialized leaf, especially one associated with a reproductive structure such as a flower, inflorescence axis, or cone scale." The bracts resemble rabbit ears, but ironically, Spanish lavender is rabbit-resistant and deer resistant (which is probably why there are no deer or rabbits in our urban yard!)
Meanwhile, if you've been wanting to learn more about honey bees, mark your calendar for these events in Davis and Woodland, Yolo County.
California Honey Festival: The inaugural California Honey Festival will take place Saturday, May 6 in downtown Woodland.

If you're a graduate student engaged in pollinator-related research at a California university, it might pay to present your research poster at the third annual UC Davis Bee Symposium, set Sunday, May 7 in the UC Davis Conference Center.
Not only will you get to showcase your research, but you might share in the $2500 in cash awarded to the winners: first place, $1000; second place, $750; third, $500; and fourth, $250.
The poster competition is part of the all-day informational symposium, themed "Keeping Bees Healthy," sponsored by the UC Davis Honey and Pollination Center at the Robert Mondavi Institute for Wine and Food Science, and the UC Davis Department of Entomology and Nematology.
Amina Harris, director of the Honey and Pollination Center, said participants in the research poster competition must register by April 10 (see submission form at http://honey.ucdavis.edu/events/copy_of_GraduatestudentposterSubmission2017.pdf and be present to defend their work before a panel of judges. They will receive complementary registration.
Last year UC Berkeley graduate students Sara Winsemius and Laura Ward won the poster competition with their research on "Exploring Potential Route of Neonicotinoid Exposure within Pollinator Hedgerows Adjacent to Seed-Treated Sunflower."
Other 2016 winners were:
- Second place of $750 went to UC Davis graduate student W. Cameron Jasper for his poster, "Investigating Potential Synergistic Effects of Chronic Exposure to Amitraz and Multiple Pesticides on Honey Bee (Apis mellifera) Survivorship."
- Third place of $500 went to UC Davis graduate student Britney Goodrich for her poster on "Honey Bee Health: Economic Implications for Beekeepers in Almond Pollination."
- Fourth place of $250 went to UC Davis graduate student John Mola for his poster on "Fine Scale Population Genetics and Movement Ecology of the Yellow-Faced Bumble Bee (Bombus vosnesenkii).
Judges were a trio of entomologists: Dennis vanEnglesdorp, professor of entomology at the University of Maryland, College Park; Robbin Thorp, distinguished emeritus professor of entomology at UC Davis; and Quinn McFrederick, assistant professor of entomology, UC Riverside.

The joy of the season strikes a chord.
When bees slip out of their California hives during winter sun breaks, they often head over to mallow blossoms to grab some nectar and pollen. A favorite is the tree mallow, Lavatera maritima “bicolor," native to Mediterranean regions of the world and California. The genus derives its name from Swiss botanist J.R. Lavater, who first discovered the species in Spain. The drought-tolerant plants, which can reach 12 feet in height, are perfect for gardeners challenging the California drought!
It doesn't take long for honey bees to discover the towering blossoms. The bees buzz in and out, battling for position, jockeying for the precious pollen. Then, laden with "gold dust," they linger in flight to clean their tongues for another go-around.
Bees, we can't get enough of them! Is it spring yet?
Meanwhile, let's fast-forward to May 2017. Mark your calendars for Saturday, May 6 and Sunday, May 7. On May 6 is the inaugural California Honey Festival in Woodland, and on May 7, the fourth annual UC Davis Bee Symposium.
The California Honey Festival, co-sponsored by the Honey and Pollination Center at the Robert Mondavi Institute for Wine and Food Science, UC Davis, and the Woodland Hoteliers, is an all-day family festival that will take place on Main Street, Woodland.
“The California Honey Festival will be a great opportunity for guests to experience the full spectrum of honey flavor,” said Honey and Pollination Center director Harris, who is coordinating the festival's educational content. “Not all honey tastes the same! Like wine, varietals of honey flavors and aromas can be very distinct. We developed our Honey Flavor Wheel in 2015 to help teach people about the nuances of honey flavor.”
In addition to tasting honey, festival goers can learn about honey bees, their pollination services, and the health benefits of honey. They can sample specialty meads or “honey wine”; taste honey-inspired food and beverages, and purchase honey and bee-themed gifts. Other family friendly activities will include a bee-themed play structure for kids, cooking demonstrations featuring honey, and informational sessions on beekeeping basics and bee-friendly gardening. More information on the California Honey Festival, including sponsorships and vendor details, is available on the festival website, www.CaliforniaHoneyFestival.com
And the next day, Sunday, May 7, is the fourth annual Bee Symposium, co-sponsored by the Honey and Pollination Center and the UC Davis Department of Entomology and Nematology. The day-long event will focus on bee health and best management practices. It will feature keynote speakers, panel discussions, a luncheon, and a graduate student poster contest, among other activities. It's a mingling of bee scientists and researchers, beekeepers and others interested in bee health. Details are pending.
Stay tuned!
