A gold rush of sorts.
When the female Valley carpenter bees forage among the passion flowers (Passiflora), they turn from solid black to a mixture of gold and black.
The pollen on their head, thorax and abdomen stands out like magical gold dust, as if sprinkled by the Good Fairy.
On a recent photo expedition in west Vacaville, we watched Gulf Fritillary butterflies (Agraulis vanilla) colonize a passionflower vine (Passiflora incaranata). Meanwhile, these huge Valley carpenter bees buzzed in and out of the purple-centered white flowers.
A golden opportunity, to be sure.

The California Buckeye (Junonia coenia), with its bold eyespots and white bars, is an easily recognizable butterfly.
The problem: getting close enough for a photo and then patiently waiting for it to open its wings. At the first indication of danger, it flutters away.
The eyespots are supposed to scare away predators, but they certainly don't scare away a praying mantis.
Kristen Kolb, master gardener extraordinaire who helps tend the Häagen-Dazs Honey Bee Haven at the Harry H. Laidlaw Jr. Honey Bee Research Facility on Bee Biology Road, University of California, Davis, recently spotted a ripped-apart Buckeye in the sedum.
We suspect a praying mantis grabbed it and feasted on the head, thorax and abdomen, leaving behind the wings.
The wings with the bold eyespots.

In the big, beautiful butterfly world, the Fiery Skipper stands out as the most common urban butterfly in California.
It may not be as showy as the Monarch, the Gulf Fritilliary and the Painted Lady, but the Fiery Skipper (Hylephila phyleus) holds its own.
Butterfly guru Art Shapiro, professor of evolution and ecology at UC Davis, describes it as "California's most urban butterfly, almost limited to places where people mow lawns. Its range extends to Argentina and Chile and it belongs to a large genus which is otherwise entirely Andean."
"Here in California, the oldest Bay Area record is only from 1937," he writes on his butterfly website. "At any rate, it is multiple-brooded, and appears to experience heavy winter-kill in most places; scarce early in the season, it spreads out from local places where it survived, gradually reoccupying most of its range by midsummer and achieving maximum abundance in September and October."
It breeds mostly on Bermuda grass (Cynodon dactylon), Shapiro says.
We've seen the adults nectaring on sedum, lantana, zinnias and Mexican sunflowers (Tithonia) at the half-acre bee friendly garden, the Häagen-Dazs Honey Bee Haven, located next to the Harry H. Laidlaw Jr. Honey Bee Research Facility on Bee Biology Road, University of California, Davis. It's like their favorite restaurant where they can order nectar (take-out, please!) from sedum, zinnias, catmint and those glorious Mexican sunflowers.
Since the Fiery Skippers don't take kindly to cold winters, let's enjoy them while we can.

The Gulf Frit is definitely back.
Back in September of 2009, butterfly expert Art Shapiro, professor of evolution and ecology at the University of California, Davis, excitedly announced the re-appearance of the Gulf Fritillary butterfly (Agraulis vanillae) in the Sacramento metropolitan area after a four-decade absence, and in the Davis area after a 30-year absence.
It's a tropical and subtropical butterfly with a range that extends from the southern United States all the way to central Argentina.
The Gulf Frit is a beautiful butterfly with bright orange-red wings, spangled iridescent silver on the underside, and a four-inch wingspan.
The larvae or caterpillars of the Agraulis vanillae feed on the leaves of the passion flower vine; they eat "many but not all species of the genus Passiflora," Shapiro says. "There are no native members of this genus in the state of California, but several are widely cultivated in gardens."
No one knows exactly when the first Gulf Frit first arrived in California, but "it was already in the San Diego area by about 1875, Shapiro says, and it was first recorded in the San Francisco Bay Area around 1908.
The showy butterfly colonized both south Sacramento and the Winding Way/Auburn Boulevard area in the 1960s but by 1971 "apparently became extinct or nearly so," recalled Shapiro, who moved to the Davis area in 1971.
The butterfly can breed where there is a "critical mass" of these plants in a town or neighborhood," he told us back in 2009.
Well, there's a thriving passion flower vine behind a west Vacaville residence that makes one think: "Critical mass!"
On one recent sunny afternoon, we spotted about 10 to 12 Gulf Frits breeding on the vine. Squadrons of brightly colored orange and black caterpillars munched on the leaves.
Yes, the Gulf Frit is alive and well.
Very alive and very well.
So if you have a passion for the Gulf Frit, plant Passiflora.
Plant it and they may come.

The folks who devote their entire lives to honey bees--how do they begin?
Well, if you're Eric Mussen, Extension apiculturst at the University of California, Davis, it begins in childhood with a fascination for insects and the walks in the woods with your grandfather, who explains the flora and fauna to you.
Then when you graduate from college and attend graduate school, your mentor makes sure you're stung by a bee before you can join his research team.
M.E.A. "Mea" McNeil tells the story of Eric Mussen in a fascinating two-part series in recent editions of the American Bee Journal.
Honey bee guru Eric Mussen, a fixture in the Department of Entomology since 1976, will do just about anything to help the bees and the beekeeping industry. He fields calls from his Briggs Hall office from commercial beekeepers, small-scale beekeepers, hobbyists, beginning beekeepers, 4-H'ers, pest control advisors, growers, assorted industry representatives, legislators, news media and the general public.
And that's just to name a few. Fact is, he'll answer any question from the simple to the complicated.
One of my favorite photos of Eric Mussen is really of a bee stinging him at the Harry H. Laidlaw Jr. Honey Bee Research Facility at UC Davis. At the time, we were doing a hive check and an irritated bee landed on his wrist.
"It's going to sting me," he said, alerting me to a pending "photo opportunity." He knew my macro lens was ready to go. Eight frames a second.
One of them is below.
I told him he could be my "hit man" any time.

Pro bee, all the way.
