It's time to pop open a bottle of champagne and do a happy dance.
Finally, finally, we saw a yellow-faced bumble bee (Bombus vosnesenskii) in our yard.
After a 20-year absence.
Dusted with yellow pollen, it (or rather he) was nectaring the rock purslane--he, along with assorted honey bees and hover flies.
This Bombus brought to mind the May 27th Webinar that bumble bee expert Robbin Thorp, emeritus professor of entomology at UC Davis presented on "The Plight of the Bumble Bees" at UC Davis.
At the Webinar, he focused on Franklin's bumble bee (range of southern Oregon and northern California) and now feared extinct.
Thorp, a fellow of the California Academy of Sciences since 1986, is a noted authority on bumble bees. In June he served as a key speaker at a public symposium on "The Plight of the Bumble Bees" at the Smithsonian Institution, Washington, D.C. His topic: "Western Bumble Bees in Peril."
Bumble bees need our protection.
As Thorp says: "“The loss of a native pollinator could strike a devastating blow to the ecosystem, economy and food supply."

You've probably seen carpenter bees engage in the practice known as "nectar robbing."
Due to their large size, they cannot enter tubelike blossoms such as salvia (sage), so they slit the base of the corolla. They rob the nectar without pollinating the flower.
But have you ever seen a honey bee come along and enter the very spot of a corolla that a carpenter bee has pierced?
We saw a honey bee do just that at the UC Davis Arboretum last weekend.Maybe this UC Davis bee was "smarter" than the average bee?

Pollen-packing honey bees dangling from gaura (Gaura linheimeri) are a joy to photograph.
Gaura, native to Louisiana, Texas and Mexico, is a long-stemmed plant with a burst of pinkish-white petals that resemble whirling butterflies.
A member of the Onagraceae family (think primroses, fireweed and fuchsias), it's a perennial that needs little care.
Gaura! Gaura! Gaura!

Don't know if silence is GOLDEN, but Italian honey bees definitely are.
Early morning Saturday, I watched a bee the color of liquid gold nectaring the lavender in our yard.
A golden opportunity to capture her brilliance. She won't live long. Field bees live only four to six weeks in the peak season, so in a few weeks she'll be gone. Others will take her place.
A click of the shutter and a moment preserved in time.
Meanwhile, work is progressing on the Häagen-Dazs Honey Bee Haven, a half-acre bee friendly garden situated next to the Harry H. Laidlaw Jr. Honey Bee Research Facility, University of California, Davis.
By mid-October it will be finished and ready for golden moments--for the honey bees and the visitors. The haven will be a year-around food source for bees. Plus, it is expected to increase public awareness about the plight of bees AND help visitors glean ideas about what to plant in their own gardens.
Lavender is one of them.

Carpenter bees (Xylocopata tabaniformis orpifex) can't get enough of the day lilies in our yard.
In the early morning, they buzz into the patch of day lilies to forage for nectar and pollen. When they're finished, it's easy to tell where they've been: they're covered with telltale yellow pollen.

What a contrast.
And definitely worthy of a photograph.
