Ready or not, here I come!
"Wait, can you slow down a bit?" I ask. "I can't focus when you move so fast!"
No, sorry! I'm in a hurry!
Anthophora urbana, a solitary, ground-nesting bee, frequents our garden to forage on the catmint (Nepeta) and lavender (Lavandula). This bee is also called an urbane digger bee (see BugGuide.net).
This one encountered a honey bee, partly obscured by the foliage, but neither seemed bothered.
California is home to more than 1600 wild bees, including A. urbana, according to the University of California-authored book, California Bees and Blooms: A Guide for Gardeners and Naturalists (Heyday). They "populate and pollinate our gardens, fields, and urban green spaces," the authors say.
That they do. And there's a very good reason why this bee is photographed more often on flowers than in flight.
Sorry, I'm in a hurry!
So here's this Gulf Fritillary (Agraulis vanillae) clinging to a lavender stem in our pollinator garden.
It is all alone--for a little white.
Then here come honey bees seeking to forage on the lavender, too.
One bee buzzes next to the butterfly's wing. Then it soars up and over.
Too much traffic for this butterfly. It moves to the nearby catmint patch.
The showy butterfly, a brilliant orange-reddish masterpiece with silver-spangled underwings, first appeared in California in the vicinity of San Diego in the 1870s, according to noted butterfly researcher Art Shapiro, professor of evolution and ecology at the University of California, Davis. He's been monitoring the butterfly populations of central California since 1972 and maintains this website.
From San Diego, “it spread through Southern California in urban settings and was first recorded in the Bay Area about 1908," says Shapiro. "It became a persistent breeding resident in the East and South Bay in the 1950s and has been there since.”
Shapiro says it “apparently bred in the Sacramento area and possibly in Davis in the 1960s, becoming extinct in the early 1970s, then recolonizing again throughout the area since 2000.”
The Gulf Frit's host plant is the passionflower vine (Passiflora). Plant it and they will come. Plant some lavender and catmint, too, for food sources. You'll be rewarded by the joy of seeing these beautiful masterpieces fluttering into your yard./span>
Just call it a missed opportunity.
Catmint (genus Nepeta) draws scores of insects, from honey bees to leafcutter bees to European wool carder bees.
It also draws spiders.
We usually see a cellar spider (family Pholcidae) trapping prey in its web. It inflicts a fatal bite and then wraps it for later consumption.
This cellar spider, however, crawled along a catmint stem to wait for prey. A honey bee buzzed down and began nectaring one of the lavender blossoms.
It was not aware of the predator. Just as the spider moved toward it, the bee took off.
Later we saw the cellar spider wrapping prey. A closer look revealed it was not a honey bee, a leafcutter bee or a European wool carder bee.
It was another cellar spider. Sexual cannabalism? Maybe. A very hungry cellar spider inept at catching a bee so it nailed a fellow spider instead? Perhaps.
At any rate, that was "what's for dinner."
We captured these photos today of a honey bee nectaring on catmint (genus Nepeta). The bee was moving fast. To blur the wings, we set the shutter speed at 1/640 of a second with an f-stop of 13 and IS0 of 800.
But just how fast can a honey bee fly?
Its wings beat 230 times every second, according to Douglas Altshuler, a researcher at California Institute of Technology who co-authored research, "Short-Amplitude High-Frequency Wing Strokes Determine the Aerodynamics of Honeybee Flight," published in December 2005 in the Proceedings of the National Academy of Sciences.
"The honey bees have a rapid wing beat," he told LiveScience in an interview published in January 2006. "In contrast to the fruit fly that has one-eightieth the body size and flaps its wings 200 times each second, the much larger honeybee flaps its wings 230 times every second."
"And this was just for hovering," Altshuler said. "They also have to transfer pollen and nectar and carry large loads, sometimes as much as their body mass, for the rest of the colony."
The Hive and the Honey Bee, the "Bible" of beekeeping, indicates that a bee's flight speed averages about 15 miles per hour and they're capable of flying 20 miles per hour.
If they're not carrying nectar, pollen, water or propolis (plant resin), they'll fly much faster!
Don't ever call the European wool carder bee (Anthidium manicatum) a slow poke. It's not "as fast as a speeding bullet" (Superman), but close.
The males, quite territorial, chase away other pollinators, including honey bees, sweat bees and butterflies.
The European wool carder bee gets it name from the fact that females collect or "card" leaf fuzz for their nests. Today we watched the bees sip nectar from our catmint blossoms and mate.
If you've never seen them in California, that's because they haven't been here that long. Originating from Europe, these bees became established in New York in 1963, and began spreading west. Bee scientists first recorded them in California (Sunnyvale) in 2007.
