Horticulture experts at the UC Davis Arboretum and Public Garden will join forces with the Yolo County Master Gardeners on Sunday, Sept. 24 to present a free workshop on "Pollinator Gardening."
The event takes place from 10 a.m. to noon in the Arboretum Teaching Nursery on Garrod Drive, UC Davis campus.
They'll tell you how to enrich your environment with bees, butterflies, hummingbirds and other pollinators.
They offer these points on their UC Davis Arboretum website:
- Learn why creating pollinator-friendly habitats in your home landscape is of the utmost environmental importance
- Gain knowledge about the top, locally-appropriate plants for attracting hummingbirds, bees and butterflies
- Find information specific to native pollinators and attracting certain species to your garden
- Tour the UC Davis Arboretum and Public Garden's newest pollinator-friendly gardens
- Get the latest landscape water conservation tips, news and more from the City of Davis
- Take a pre-sale nursery tour courtesy of Nursery Manager Taylor Lewis (Actual plant sales will not be taking place until our first plant sale event on October 7.)
- Prep your shopping list for the Friends of the UC Davis Arboretum and Public Garden's upcoming fall plant sales
To those, we'd like to add three more reasons:
- It's a great opportunity to immerse yourself in the beauty of nature. It's about the passion, persistence and poetry of nature.
- It's exciting to see how many pollinators visit--or reside in--your garden. Plant 'em and they will come!
- It's indeed challenging, but highly rewarding to capture images of the pollinators (see below). It's also highly addictive.
We have bright faces in our Vacaville, Calif., pollinator garden.
The bright faces are usually that of assorted bees and butterflies nectaring on members of the sunflower family: Mexican sunflower (Tithonia) and blanketflowers (Gaillardia).
But we did not expect to see this bright face: a banded garden spider, Argiope trifasciata. Bright face? Argiope is Latin for “with bright face” while trifasciata is Latin for “three-banded.”
The Argiope trifasciata spider is found throughout much of the United States and Canada. It's also in Central and South America, Australia, the Mediterranean region, Africa, Sri Lanka, the South Pacific Islands, and China, according to Spiders of North America, which informs us that scientists have identified a combined total of 4000 spider species in the United States and Canada.
Argiope trifasciata is just one of them, but what a beautiful spider it is. Clever and cunning, too.
It had crafted a web inches from the ground between a showy milkweed, Asclepias speciosa, and bluebeard (Caryopteris clandonensis) amid patches of Mexican sunflower patch and African blue basil.
Exactly where the bees are.
It snared two of them one morning and wrapped them for later consumption.
Meanwhile, an opportunistic and hungry freeloader fly, family Milichiidae and maybe genus Desmometopa, figured the spider ought to share its prey. It stopped to feed on the wrapped bee.
So, in actuality, there were two bright faces in the garden--the banded garden spider and the freeloader fly.
The faces of the wrapped honey bees--not so much.
A partial solar eclipse is about to happen in Vacaville, Calif.
I am watching the insects: the honey bees nectaring on the African blue basil, an orbweaver spider munching on its prey, an assassin bug poised on a tropical milkweed, and a praying mantis lurking beneath a showy milkweed leaf.
Today (Aug. 21) is the long-awaited Great American Eclipse. The totality path will begin at 9 a.m. in Oregon, and stretch across the country to South Carolina.
Hmm, I wonder, how will the bugs in our pollinator garden react to a partial eclipse?
It won't be drastic, I predict. And it wasn't.
The partial eclipse in Vacaville began at 9:02 a.m. and reached its maximum (70 percent coverage of the sun) at 10:16. It ended at 11:38 am., a duration of two hours and 36 minutes.
The bees foraged before, during and after the eclipse, primarily on the African blue basil, which is usually covered with bees. During the height of the eclipse, however, as the skies darkened, a little more than half remained. After the eclipse, when the temperature increased and the wind ceased, the number of bees returned to normal.
"Honey bees tend to act like night is falling if the eclipse takes out quite a bit of the sunlight," says honey bee guru Eric Mussen, Extension apiculturist emeritus and president of the Western Apicultural Society. "Then they 'wake back up' afterwards."
Despite the eclipse, the spider kept eating its prey. (Sure hope it wasn't that blue dragonfly, Libellula luctuosa, "the widow skimmer" I saw yesterday.) The praying mantis kept lurking. The assassin bug raised its antennae. And the bees--although fewer of them--just kept foraging.
Two stink bugs opted to procreate on the bluebeard, Caryopteris x clandonensis. A Gulf Fritillary fluttered by and stopped to sip nectar from the Mexican sunflower (Tithonia). The assassin bug crawled higher on the milkweed, poised for an ambush.
The spider tugged its prey beneath a leaf, abandoning its web. Well, that's that, I thought.
Not so. The sticky web snagged a honey bee while the spider was polishing off its first prey. Okay, spider, you've already had your breakfast. You don't need a second helping. Not today."
I freed the struggling bee and off it buzzed to forage another day.
A partial eclipse, but a full escape...
One of Buck Owens' signature songs that never failed to please his fan base was "I Got a Tiger by the Tail."
The Country-Hall-of-Fame singer, who died in 2006 at age 76, said the lyrics came to him after he noticed a gas station sign advertising "Put a tiger in your tank." (Source: Wikipedia)
"I've got a tiger by the tail, it's plain to see," sang Buck Owens. "I won't be much when you get through with me..."
Well, he's not the only one with a "tiger by the tail."
We recently spotted male longhorn bees, probably Melissodes agilis, targeting Western tiger swallowtails, Papilio rutulus, in our family's pollinator garden in Vacaville, Calif. The butterflies were trying to sip nectar from the 8 to 10-foot-high Mexican sunflowers (genus Tithonia).
Who knew that sipping nectar could be so difficult? The extremely territorial male longhorn bees kept trying to push the "tigers" off the Tithonia by dive-bombing them, slamming into them, and then regrouping for more aerial assaults. Their goal: to save the resources for their own species.
And then it happened. A longhorn bee slid through a tiger's tail.
A tiger by the tail.
It was not a good way to welcome an admiral.
The Red Admiral butterfly, that is.
The Vanessa atalanta fluttered into our pollinator garden on Sunday, July 16 in Vacaville, Calif., and touched down on a Mexican sunflower (Tithonia).
The warmth of the sun, the rich nectar, a soft breeze, and all was well.
For a little while.
Several territorial male long-horned bees spied the stranger and pulled out the welcome mat. In a frenzy, they began dive-bombing the colorful black and red butterfly, trying to chase it away. "Those flowers are for our girls!" they seemed to say. "Leave! Now!"
Everywhere the butterfly went, a squadron of bombers followed. The sailboat-like wings proved a clear target.
One bullet-of-a-bee, probably a Melissodes agilis, slammed into the butterfly's wings, and that was enough.
"This pollinator garden's not big enough for both of us!"
