We're almost midway through National Pollinator Week!
It's a week that we should celebrate every day.
Last weekend we spotted a newcomer to our backyard bee garden: a bumble bee species, Bombus fervidus, formerly known as Bombus californicus, as identified by native pollinator specialist Robbin Thorp, emeritus professor of entomology at the University of California, Davis, and bumble bee enthusiast Gary Zamzow of Davis.
The female was heading toward a purple coneflower, Echinacea purpurea, and then touched down in a "Queen-of-the-Mountain" moment.
This bumble bee species is commonly known as "the yellow bumble bee," according to the co-authors of the newly published Bumble Bees of North America: an Identification Guide, authored by Paul Williams, Robbin Thorp, Leif Richardson and Sheila Colla (Princeton University Press).
It's widely spread across the continent. "Evidence from DNA barcodes supports a close relationship between individuals with the darker color pattern in the west (named californicus) and individuals with the lighter color patterns in the east (named fervidus)," they wrote.

Did you count pollinators on Thursday, May 8?
That was "Be a Scientist Day," sponsored by the UC Agriculture and Natural Resources' Day of Science and Service to commemorate 100 years of Cooperative Extension.
UC ANR asked that you take three minutes out of your day and count the honey bees, bumble bees and butterflies and other pollinators.
Amina Harris and Art Shapiro did.
In the Good Life Garden.
It's a little treasure located in the courtyard of the Robert Mondavi Institute for Wine and Food Science on the UC Davis campus.
The Good Life Garden's ever-changing edible landscape features lots of organic and sustainably grown vegetables, herbs and flowers--all for the faculty, students, staff, and visitors to enjoy.
And for pollinators, too.
Harris, director of the Honey and Pollination Center, and Shapiro, a butterfly expert and distinguished professor of evolution and ecology at UC Davis, happened to be enjoying the garden at the same time.
The count: 150 honey bees, two yellow-faced bumble bees (Bombus vosnesenskii) and one skipper butterfly. Most of them were foraging on the lavender or the catmint.
As a bonus, they saw dozens of lady beetles and immature lady beetles.
A good life. A very good life. A very good life in the Good Life Garden.

Do you now where the bees are?
On Thursday, May 8 let's all step outside for three minutes and count the honey bees and other pollinators.
It's all part of the "Day of Science and Service" sponsored by the University of California Agriculture and Natural Resources (UC ANR).
If you're lucky, you'll find multiple pollinators sharing a single flower. Maybe the foragers will all be honey bees, our prime pollinators!
We took this photo of four honey bees vying for the same spot on a pomegranate blossom. A hot spot.
It reminded us of humans fighting for a single parking space during the holiday season and then racing into a store and battling over a special gift (that will likely wind up at a garage sale in several months).
In this case, the reward was nectar. Sweet nectar.

If you want to learn more about honey bees and other pollinators, then “The Bounty of Pollination: More Than Just Honey” is the place to “bee” on Saturday, Oct 27 at the Robert Mondavi Institute for Wine and Food Science (RMI), University of California, Davis.
This will be the "debut event" of the Honey and Pollination Center of RMI, according to event coordinator Tracy Dickinson.
The public event, to take place from 1 to 5:30 p.m. in RMI's Silverado Vineyards Sensory Theater, is billed as “an afternoon of lively discusssions, unique tastings and interesting displays on the science behind honey and the important (and surprising) non-honey bee pollinators."
RMI is in the process of lining up speakers and displays.
Registration opens in August. The cost per ticket is $60, with discount prices offered for UC faculty, staff and students. The last day to register online is Friday, Oct. 26.
UC faculty staff and students may obtain a coupon code for discounted tickets through firstname.lastname@example.org. Or, if folks want to become a Friend of the RMI, they need to contact Kim Bannister at email@example.com.

When you see the blow fly (below), what do you think?
Well, that depends on who you are and what you do--or maybe your earliest negative/positive insect recollections.
If you hate flies, particularly blow flies, and you despise their larvae (maggots), your response is probably "Yecch!"
If you're an artist, you might think, "Look at that metallic green sheen and those red eyes!"
If you're a photographer: "What kind of camera and macro lens did you use?" (Nikon D700, 60mm)
If you're into flowers, you might say "Ah, a New Zealand tea tree--Leptospermum scoparium. Fly? What fly? Is there a fly there?"
If you're a beekeeper and see only the Leptospermum scoparium: "Manuka honey!"
If you're a medical doctor and treat wounds: "Maggot therapy!"
If you're an entomologist, particularly a forensic entomologist: "Nice!"
And if you've ever visited the UC Davis Department of Entomology displays at Briggs Hall during the annual campuswide Picnic Day, you''re probably thinking "Maggot Art!" and "When's Picnic Day?" (Note: this year's Picnic Day is April 21, and yes, you can create Maggot Art (take a bow, Rebecca O'Flaherty).
However, if you're an entomologist with a keen interest in insect ecology and insect/plant interactions, the blow fly will bring out the "P" word in you: "Pollinator!"
Honey bees, native bees, butterflies, hummingbirds, bats and the like are all pollinators. But so are flies, including syprhid flies and yes, blow flies.
