By day, they fly around our yard looking for the girls.
At night, it's "Boys' Night Out."
These males, longhorned digger bees, Melissodes agilis (as identified by native pollinator specialist Robbin Thorp, emeritus professor of entomology at UC Davis), are absolutely spectacular. At night the males roost on our lavender stems, sometimes 8 to 10 on a single stem. Their "bedroom" gets quite crowded.
Melissodes are ground-nesting solitary bees. While the males sleep overnight on the flowers, each female is tucked away in her ground nest.
According to the Discoverlife.org: "With the apparent exception of Florida, agilis occurs throughout the United States, Southern Canada and Northern Mexico, and is in flight from May to November in the East."
Christopher O'Toole and Anthony Raw write in their book, Insects of the World, that Melissodes are found on all continents except for Australia. "The males of nearly all species have very long antennae and are colloquially known as 'longhorned bees.'"
These bees frequent plants of the sunflower family, Helianthus. In our yard, they gravitate toward the blanket flowers (Gallardia) and Mexican sunflower (Tithonia).
We've found them "going to bed" at 6 p.m. and rising around 7 a.m. We clocked one "sleepy head" getting up at 10:30 a.m. as honey bees and bumble bees buzzed around him, foraging for nectar on the lavender.
That was on Sunday, Father's Day.

Bees, butterflies and sunflowers at the California State Fair?
The state fair, which opened July 12 and ends July 28, is a good place to see a bee observation hive, honey bees on sunflowers, carpenter bees on petunias, and butterflies in the Insect Pavilion, aka Bug Barn.
If the purpose of a fair is to educate, inform and entertain, then that's what this fair does. A recent stop at the 160th annual fair provided a glimpse of what's going on in the entomological world--and what shouldn't be going on in the petunia patch.
At the California Foodstyles in the Expo Center, beekeeper Doug Houck of the Sacramento Area Beekeepers' Association and his daughter, Rebekah Hough, urged folks to find the queen bee, worker bees and drones in the bee observation hive. Then the fairgoers sampled the honey.
At the Bug Barn, mounted butterflies drew "oohs" and "ahs." Just a few of the butterflies: Monarchs, Western Tiger Swallowtails, Great Purple Hairstreaks, Dusty-Winged Skippers, Red Admirals, and Painted Ladies. The Bohart Museum of Entomology at UC Davis, home of nearly eight million specimens, provided some of the butterflies.
Outside the Insect Pavilion, a garden thrived with tall-as-an-elephant's-eye sunflowers. Honey bees and sunflower bees buzzed among the heads--sunflower heads and fairgoers' heads.
The most disconcerting scene: teenagers screaming when they heard and saw the female Valley carpenter bees nectaring petunias. "Ick, big black bees!" said one as she quickly ran off.
"Carpenter bees," a middle-aged bystander commented dryly as she sauntered off to see the sturgeon display.
Another teenager approached the petunia patch, and she, too, bolted. "They're going to sting me!" she yelled.
It's rather sad that the first reaction on seeing bees in a flower bed is not "pollinator" or "pretty flowers" or "pink petunias" but "sting."
When did "Big Fun" become "Big Scare?"

You can tell it's summer along Yolo County roads by the acres and acres of sunflower fields.
Looking like real-life Van Gogh paintings (Van Gogh painted them in vases, Mother Nature paints them in rows), the sunflower fields are nothing short of spectacular. With tousled heads rising toward the sun and golden locks nodding in the breeze, they stand their ground.
Sunflowers (Helianthus Annuus), native to North America, are one of our most recognizable flowers. They're a good food source, a designer's dream, and dugout tradition.
Earlier this year we fielded a call from a young man from southern California who wanted to know when the sunflowers would bloom in Yolo County. He wanted to propose to his girlfriend in a sunflower field.
This is one agricultural crop that does not go unnoticed. Not by people, not by animals, not by birds, and especially not by honey bees and sunflower bees.

Sunflowers, native to the Americas, are spectacular, especially when you encounter a field of them. If you look closely, you'll see honey bees, sunflower bees and bumble bees working the flowers.
It's pollination at work.
To encourage backyard gardeners to grow sunflowers and collect data about the bees that visit them, the Great Sunflower Project provides free seeds and educational information.
You can obtain the Lemon Queen sunflower seeds from the Great Sunflower Project, from a local nursery or from a seed catalog.
Associate professor and biologist Gretchen LeBuhn of the University of California, Santa Barbara, started the project in 2008 as a way to get citizens interested in bee pollination.
"In 2008, we started this project as a way to gather information about our urban, suburban and rural bee populations," writes LeBuhn, considered "the queen bee" of the Great Sunflower Project. "We wanted to enlist people all over the U.S. and Canada to observe their bees and be citizen scientists. We asked them to plant sunflowers in their gardens so we could standardize study of bee activity and provide more resources for bees. Sunflowers are relatively easy to grow and are wildly attactive to bees."
Since 2008, the Great Sunflower Project has expanded its list of plants studied to include bee balm, cosmos, rosemary, coreopsis (tickseed), and purple coneflower.
"It’s time to turn off your television, take off those earphones, shut down that computer, go outside, and rediscover the wonder of nature," LeBuhn says.
That's one small step toward improving bee habitat--and human habitat, too.
