“Bay Area’s ‘urban’ bees like native, diverse plantings”

By Lou Fancher via mercurynews.com

Bay Area's 'urban' bees

Dr. Gordon Frankie said native bees have preferences, and knowing what they like can improve the health of your garden.

“If they have a choice, they’ll go after native plants,” said Frankie, a professor and research entomologist at UC Berkeley. He and Steve Gentry, a founding member of the Mount Diablo Beekeepers Association, teamed up for a recent Lafayette Library Foundation Science Cafe presentation.

Frankie’s point — that local gardeners hoping to attract Agapostemon texanus or Xylocopa varipuncta, two local native bee species, should include native plants in their gardening plans. And mulching should be done lightly because 70 percent of all native bees nest in the ground and can’t burrow through materials heavier than soil.

A project at Frog Hollow Farm and other Brentwood farms is demonstrating the impact of placing native plants between crop rows.

Urban areas are ideal for bees, Frankie claimed, because of the diverse food supply they offer. The Oxford Tract Bee Garden he and his team of researchers planted allows them to monitor and categorize bees’ attraction to native and nonnative plants. A 10-city survey across California is providing a detailed picture of the bee population. San Diego, he said, is the worst city for attracting bees.

“It’s their gardening culture: No one is using diverse, floral plants,” Frankie said.

On the other end of the spectrum, a 30-by-30-foot garden in Ukiah had 68 bee species, and Santa Cruz is a hotbed beehive community. (The Bay Area is fifth on that list.)

Gentry, known by local residents as “Bee Man” — although he is considering an upgrade to “Emperor of Bees” — began the popular event’s 60-minute talk with a bucket.

“All of these products from bees are helpful to humans,” he declared, pulling hunks of beeswax and jars of honey, pollen and actual bees from the container. “Their history goes back thousands of years.”

Within five minutes, Gentry had advocated (beeswax is used for lubricants in cosmetics, candles, wax-resist dyeing and food preserving), acknowledged (“We have some hindrance about eating insects, but watch a bear break into a bee’s nest. He’ll eat the whole thing,” he said), and advertised (pollen is the new superfood, with protein, enzymes, vitamins and minerals, according to Gentry).

He also shared a 30-year-old epiphany he had while watching a black bear and her two cubs demolish a rotted tree while feasting on termites.

“I wasn’t the first person to see natural things. Forty thousand years ago, hunter-gatherers watched bears, bees and insects, too. The timeline is long,” he said.

Skipping through honeybee history, from Middle Eastern origins to monks in monasteries needing dependable light sources to small farmers before World War I who kept just enough hives to feed their families and pollinate their crops, Gentry landed on the contemporary world’s bee dilemmas.

“Industrialization changed farms. They became bigger, and now, large pollination contracts and commercial beekeeping are driving the business. (More than a million) hives are brought into the central Southern California valley for pollinating almonds each year.”

Frankie, whose business is less about keeping bees and more about watching them, asked the Science Cafe audience of gardeners, beekeepers and general science fans a series of questions.

Delighting at stumping his listeners, he said 1,600 bee species were attracted to California’s 5,000 flowering plants, drawing a hefty percentage of the United States’ 4,000 total bee species.

“Notice, you are not on their list,” he said. “Bees are vegetarians. They’re not after you or your burgers. Wasps are the ‘meat bees’ after your burgers.”

Generating a local buzz
The University of California Press will publish Gordon Frankie’s findings in a forthcoming book, “Native Bees and Their Flowers in Urban California Gardens.” Bee appreciators who don’t want to wait can find information at http://nature.berkeley.edu/urbanbeegardens/index.html and diablobees.org.

ARTICLE via The Onion: Beard of Bees

Bee Beard

BURLINGTON, VT—Complaining of patchiness and uneven color, area man Matthew Cruickshank, 34, told reporters Monday that he has always had trouble growing a full beard of bees. “For some reason, when the bees come in they just won’t connect my mustache to my goatee, and they seem to thin out halfway up my cheek,” said Cruickshank, examining a beeless patch of skin on his neck and noting how one random gray bee always appears in the middle of his chin. “It’s strange because my dad always had a full, thick beard of bees his whole life. I guess some guys are just lucky that way.” Cruickshank added that although he grooms his beard of bees frequently, it often becomes itchy and uncomfortable, especially at night when he’s trying to sleep.

Happy St. Gobnait’s Day!

St. Gobnait

St. Gobnait – Patron Saint of Bees and Beekeepers

“Saint Gobnait’s Day is Feb 11th is still celebrated by the community of Ballyvourney, in County Cork. During a Mass at the well, everyone takes water from it.

Gobnait (Gobnet, Gobhnet, Gobnaid, Gobnata, or Gobnatae), was born in County Clare, Ireland, sometime in the 5th or 6th century. Gobnait is Irish for Abigail (“Brings Joy”). As the patron saint of beekeepers, her name also has been anglicized as Deborah, meaning ‘Honey Bee’…

One of the miracles attributed to Saint Gobnait was that she protected a parish by unleashing a swarm of bees… She had a strong relationship with bees and used the properties of honey in the treatment of illness and healing of wounds.”

ARTICLE: San Francisco beekeeping

via baynature.org

Eye-level with the eucalyptus canopy of Golden Gate Park, Charlie Blevins stands on his San Francisco rooftop and begins to “suit up.”

He slips on a white jacket, then pulls a spacesuit- like hood over his head that masks his face with a netted veil. A pair of thick, white gloves drawn on and Blevins is ready for “inspection.” He gently pulls a honeycomb frame from the hive.

This is from one of 35 beehives that the San Franciscan beekeeper maintains in the backyards and rooftops of Bay Area properties. Is the queen laying eggs? Is the colony in tip-top shape? Are honey stores adequate? Blevins, a cheery and warm-hearted man in his late 50s, asks himself these questions as he checks each hive for signs of disease.

“You can tell a lot about the egg-laying pattern of the queen. If the queen is not laying, then the hive will die. Bees only live six weeks,” said Blevins.
Honeybee populations are in deep trouble around the world, but in places like San Francisco, urban beekeepers are doing their part to restore the enterprising Apis to their crucial role as ecosystem pollinator. Urban beekeeping is an outgrowth of the local food movement, which has inspired countless farms in urban pockets and has stoked the dream of sustainable cities. Behind every urban beehive is the beekeeper.

Bees and Math

Bees and Math

“Bees…by virtue of a certain geometrical forethought…know that the hexagon is greater than the square and the triangle, and will hold more honey for the same expenditure of material. — Pappus of Alexandria

Bees have not studied tessellations theory. However, some of their behavior patterns can be explained mathematically. One such phenomena which mother nature instilled in the bee is the nature to use the least expenditure of energy and materials. The bees somehow know that the square, the triangle and the hexagon are the only three self-tessellating regular polygons. Of the three, the hexagon has the smallest perimeter for a given area. So, when bees are constructing hexagonal prism cells in the hive, they use less wax and do less work to enclose the same space than if tessellating space with prisms of square or triangular bases. The honeycomb walls are made up of cells which are 1/80 of an inch thick, yet can support 30 times their own weight. A honeycomb of 14.5”x8.8” can hold more than five pounds of honey. That also explains why they are so heavy. The bees are creating hexagonal prisms in three rhombic sections, and the walls of the cell meet at exactly 120 degree angles. What is even more amazing, is the fact that the bees work simultaneously on different sections forming a comb with no visible seams. It is built vertically downward, and the bees use parts of their bodies as measuring instruments. In fact, their heads act as plummets.”

ARTICLE: Insecticide ‘unacceptable’ danger to bees, report finds

“Campaigners say the conclusion by the European Food Safety Authority is a ‘death knell’ for neonicotinoid pesticides

The world’s most widely used insecticide has for the first time been officially labelled an “unacceptable” danger to bees feeding on flowering crops. Environmental campaigners say the conclusion, by Europe’s leading food safety authority, sounds the “death knell” for the insect nerve agent…

Bees and other pollinators are critical to one-third of all food, but two major studies in March 2012, and others since, have implicated neonicotinoid pesticides in the decline in the insects, alongside habitat loss and disease. In April, the European commission demanded a re-examination of the risks posed by the chemicals, including Bayer’s widely used imidacloprid and two others…

“This is a major turning point in the battle to save our bees,” said Friends of the Earth’s Andrew Pendleton: ‘EFSA have sounded the death knell for one of the chemicals most frequently linked to bee decline and cast serious doubt over the safety of the whole neonicotinoid family. Ministers must wake up to the fact that these chemicals come with an enormous sting in the tail by immediately suspending the use of these pesticides.’”
