Quick! Find the damselfly!
This damselfly (below) is so camouflaged that it's difficult to see her.
Her? She's a female Argia vivida, as identified by Lynn Kimsey, director of the Bohart Museum of Entomology and professor of entomology at UC Davis; and dragonfly/damselfly/butterfly aficionado Greg Kareofelas, a volunteer at the Bohart Museum.
The males are a bright blue.
We didn't see both genders, though, when we were looking for damselflies in a bed of Spanish lavender last weekend in Benicia.
Argia "is a genus of damselflies of the family Coenagrionidae and of the subfamily Argiinae," according to Wikipedia. "It is a diverse genus which contains about 114 species and many more to be described. It is also the largest genus in Argiinae. They are found in the Western Hemisphere."
Like their cousins, the dragonflies, they're predators that eat other insects.
Argia vivida are known as "dancers" because of "the distinctive jerky form of flight they use which contrasts with the straightforward direct flight of bluets, forktails and other pond damselflies," according to Wikipedia. "They are usually to be seen in the open where they catch flying insects on the wing rather than flying about among vegetation picking off sedentary prey items. They tend to land and perch flat on the ground, logs and rocks. When perched, they usually hold their wing slightly raised above the abdomen."
That's what this one was doing./span>/span>
The almonds are blooming! The almonds are blooming!
Well, at least one almond tree in the Benicia State Recreation Area is blooming. On a drive to Benicia on Christmas Day, we spotted several blooms on an almond tree. The tree, a foot from the parking lot, was getting a little southern exposure--and soaking in the warmth of the sun bouncing off the asphalt.
California almonds don't usually bloom 'til around Feb. 14--Valentine's Day--but this tree has always been an early bloomer. It was blooming on New Year's Day in 2014.
Unfortunately, the honey bees hadn't found it yet.
But they did find the Benicia Capitol State Historic Park, where jade and oxalis have burst into bloom, and they also found the winter vegetables in the Avant Community Park in downtown Benicia. The bees were working the broccoli blossoms, two bees at a time.
Who says broccoli isn't good for you?
The painted ladies are on move.
Scores of painted ladies (Vanessa cardui) are now migrating north from their overwintering sites near the U.S. Mexico border.
"Fascinatingly, they arrived in Prescott, Ariz., the same day (as the ones spotted in Benicia)," said butterfly expert Art Shapiro, distinguished professor of evolution and ecology at the University of California, Davis. "I think they're all from south of the border." The annual migration north varies, but can take place as early as late January and as late as mid-April.
The painted ladies spend the winter in the desert, where in the late winter, they breed on desert annual plants, Shapiro says. The adults emerge in February or March and immediately migrate into the Central Valley and foothills, where they breed. Around May, here in the Central Valley, you'll see the caterpillar offspring munching on borage, thistles, fiddleneck and mallows. Then the adults head toward the Pacific Northwest.
"The painted lady moves northward in a generational wave as the season progresses," Shapiro says on his website. "Frequently it disappears altogether from the lowlands in summer. Beginning in August the movement reverses and butterflies head south toward the desert wintering grounds."
"There is no evidence that this species overwinters successfully anywhere in our area, except for very rare individuals maturing in midwinter from really late autumnal larvae."
The painted lady migration may not be as popular as the monarch (Danaus plexippus) migration, but it's fascinating just the same.
Shapiro, who has monitored the butterfly population of California's Central Valley for 42 years, will be speaking at noon on Monday, March 24 on "Ecological Communities and the March of Time" in the Commonwealth Club, 595 Market St., San Francisco. For program detail and registration, please see the club website. His talk is open to the public.

Several honey bees and at least one lady beetle (ladybug), also discovered the "hot spot" in the garden as the temperatures climbed to 52 degrees.
A bumble bee in Benicia? On Christmas Day? Who would have thought?
This bumble bee species, identified by native pollinator specialist Robbin Thorp, emeritus professor of entomology at UC Davis, is one of only 250 species worldwide in the genus Bombus. It's native to North America.
Thorp is one of four co-authors of the newly published and long-awaited Bumble Bees of North America: An identification Guide (Princeton University Press). The book is billed as "the first comprehensive guide to North American bumble bees to be published in more than a century." It allows us to identify all the 46 bumble bee species found in North America, and also to learn about "evolutionary relationships, geographical distributions and ecological roles."
Lead author is Paul H. Williams, a research entomologist at the Natural History Museum in London. In addition to Thorp, other co-authors are Leif L. Richardson, a doctoral candidate in the Department of Ecology and Evolutionary Biology at Dartmouth College; and Sheila R. Colla, postdoctoral fellow at the Natural Sciences and Engineering Research Council of Canada and a project leader at Wildlife Preservation Canada.
Meanwhile, back to Benicia. Like North America's bumble bees, the Benicia Capitol has a rich history. Erected in 1852 and located at 115 West G St., it served as California's third seat of government. Legislators convened there from Feb. 4, 1853 (the year the honey bee was introduced to California) to Feb. 25, 1854.
Today, 160 years later, the Benicia State Capitol is the only surviving pre-Sacramento capitol. Let's hope we can still say that about bumble bees 160 years from now--and the years to come.
These freezing temperatures we're experiencing make us yearn for spring.
True, it's still autumn and winter doesn't officially start until Dec. 22, but it's a good time to think of honey bees pollinating the almond blossoms.
California almonds usually bloom around mid-February. We remember, however, that on Jan. 1, 2013 we spotted almonds blooming in the Benicia State Recreation Area. Guess they didn't get the message that it's not spring yet. Bees didn't get the message, either.
Then in early February we cruised over to Matthew Turner Shipyard Park, Benicia, and saw more almond blossoms and a bevy of bees flying.
Let's skip the winter solstice and head right into the vernal equinox!/span>
