It was definitely a hot spot.
Honey bees foraging last week on a pomegranate tree on Hopkins Road, west of the UC Davis main campus, competed for food on hundreds of blossoms.
We counted five honey bees on one blossom alone in what amounted to a pushing/shoving match.
Most of the bees probably came from the nearby apiary at the Harry H. Laidlaw Jr. Honey Bee Research Facility on Bee Biology Road, off Hopkins Road.
The pomegranate is an ancient fruit and the honey bee is an ancient insect. Millions of years ago, they grew up together in the Mediterranean region of southern Europe. European colonists brought the honey bee to our Eastern coast (Jamestown colony) in 1622; honey bees finally arrived in California in 1853. The pomegranate trees were introduced to California in 1769.

Mark your calenders!
The Honey and Pollination Center at the University of California, Davis, is planning a "Luncheon in the Garden" on Sunday, June 2 from noon to 3 p.m. in the Good Life Garden at the Robert Mondavi Institute for Wine and Food Science on campus.
It promises to be a delightful afternoon.
Executive director Amina Harris says it will be a "dazzling five-course meal from appetizers to cheese and desserts. Each course features honeys from around the globe."
The luncheon, open to the public, supports and introduces the Honey and Pollination Center. Food and drink will be provided by chefs, apiaries, wineries and meaderies (think wine made from honey), and the farmers of California.
What is the Honey and Pollination Center? Its vision is to establish UC Davis as a global center of excellence and education on bees, honey and pollination.
- Promote the use of high quality honey in the California market, help ensure the sustainability of honey production in California, and showcase the importance of honey and pollination to the well-being of Californians.
- Spearhead efforts to gain support and assemble teams for research, education and outreach programs for various stakeholder groups including: (1) the beekeeping industry, (2) agricultural interests who depend on bee pollination, (3) backyard beekeepers, and (4) the food industry
Its specific goals are five-fold:
- To optimize university resources by coordinating a multidisciplinary team of experts in honeyproduction, pollination and bee health
- To expand research and education efforts addressing the production, nutritional value, health benefits, economics, quality standards and appreciation of honey
- To serve the various agricultural stakeholders that depend on pollination services
- To help the industry develop informative and descriptive labeling guidelines for honey and bee-related products to establish transparency in the marketplace
- To elevate the perceived value of varietal honey to producers and consumers through education, marketing, and truth-in-labeling with the end goal of increasing the consumption of honey
Tickets are $125 per person. Like to attend? Contact events manager Tracy Diesslin at (530) 752-5233 or at firstname.lastname@example.org.

Symphony in the almond blossoms...
There's a wild almond tree planted in a field off Bee Biology Road at the University of California, Davis, that's incredibly beautiful.
Honey bees from the nearby apiary at the Harry H. Laidlaw Jr. Honey Bee Research Facility reunite on the blossoms, each bee seemingly vying for the best pollen to take back to her hive.
The tree is not quite in full bloom, but don't tell that to the bees. We captured a few images of them in flight, a moving symphony performance in the almonds.

The drama unfolds slowly.
The crafty praying mantis that's perched atop a zinnia raises its spiked, grasping forelegs and silently waits for unsuspecting prey.
A sweat bee cruises by. Then a second one. Then a third.
They do not land and the praying mantis does not move.
Is it possible for an insect to be as still as a statue? It is. Praying mantids can lie in wait for hours. When their prey comes near, they lash out and grab it, holding it in their spiked forelegs while they eat it alive.
Meanwhile, this praying mantis in the Häagen-Dazs Honey Bee Haven, a half-acre pollinator garden on Bee Biology Road, University of California, Davis, doesn't have long to wait. A honey bee lands on the predator's perch.
A predator. A prey. A pollinator garden.
The bee crawls slowly along the blossoms and is just about to forage when it spots the predator.
In a flurry of wings and legs, almost faster than a 1/640th-of-a-second shutter speed, the praying mantis lunges. Nothing but air! The bee escapes (probably in a "shudder" speed) and buzzes away.
This meal was not to bee.

Varroa mites, those pesky little parasites that suck the blood out of honey bees and spread multiple viruses, are now found throughout the world, except in Australia.
Scientists blame these parasites as one of the causes of colony collapse disorder (CCD), characterized by adult bees abandoning the hive and leaving behind the queen, brood and food stores. They attribute CCD to a multitude of factors, including pests, pesticides, parasites, diseases, viruses, malnutrition and stress. Thus, varroa mites are a key factor in the declining honey bee population.
Today's honey bees are ill-equipped to rid their hives of a varroa mite infestation. Indeed, beekeepers consider the varroa mite (scientific name Varroa destructor) as Public Enemy No. 1.
And that's one of the reasons why we like bee breeder-geneticist Susan Cobey's efforts to increase the genetic diversity in our domestic honey bee gene pool.
Cobey, who has a dual appointment at the University of California, Davis and Washington State University, is directing a stock improvement program which aims to do just that.
"Increasing the overall genetic diversity of honey bees will lead to healthier and hardier bees that can better fight off parasites, pathogens and pests," she says.
"We have collected and imported honey bee semen (germplasm) from their original European homeland to inseminate select domestic queens produced by the California bee breeders," Cobey told us. These California breeders supply queen bees and package bees nationwide. Honey bees, as Cobey points out, "provide the essential pollination for our crops, especially in California, "the breadbasket" of our country and our world.
Cobey and her team have also re-introduced the subspecies, Apis mellifera caucasica, a dark race of bee known for its collection and use of propolis, self-medicating plant resins.
What does a mite look like? Check out the mite-infested drone below. A boy bee's only duty is to gather in the drone congregation area and mate with the queen during her maiden flight, but that won't happen with this one. No thanks to the parasitic mites, he has a weakened immune system, crippling his ability to fly.
What will happen to him? His sisters will kick him out of the hive and he will die.
The lifespan of this mite-infested drone will be short. The brownish-orange "bumps" are varroa mites. (Photo by Kathy Keatley Garvey)
