It's Friday Fly Day!
And what better day than a Friday to post an image of a syrphid fly nectaring on a tower of jewels, Echium wildpretii? We all need "pretty" in our lives.
Syrphid flies, also known as "flower flies" and "hover flies," are pollinators that hover over a blossom before touching down.
"Most species are predaceous, most commonly on aphids or mealybugs," according to the UC Statewide Integrated Pest Management Program. "Some syrphids prey on ants, caterpillars, froghoppers, psyllids, scales, other insects, or mites. About 100 to 400 aphids can be fed upon by each aphid-feeding larva before it pupates, but this varies by the mature size of the syrphid relative to the aphids' size."
Folks who assume that every critter they see in, on, or around a flower is a honey bee should know a couple of distinguishing features: bees don't hover, and syrphids have only one pair of wings, while bees have two. "Their large eyes and short antenna also give them away," notes Kelly Rourke in her U.S. Forest Service article on "Syrphid Fly (Sphaerophoria philanthus). "The absence of pollinium, or pollen sacs, is more difficult to see, but is another difference from a bee. Of the nearly 900 species of flower flies (family Syrphidae) in North America, most have yellow and black stripes."
Happy Friday Fly Day!

Honey bees absolutely love African blue basil. If there ever were a "bee magnet," this plant is it.
We first learned of African blue basil, (Ocimum kilimandscharicum × basilicum 'Dark Opal'), through Gordon Frankie, UC Berkeley professor and the late Robbin Thorp, distinguished emeritus professor of entomology at UC Davis. They co-authored the book, California Bees and Blooms: a Guide for Gardeners and Naturalists with Rollin Coville and Barbara Ertter, also affiliated with UC Berkeley.
We plant it every year in our pollinator garden. Wikipedia calls African blue basil "a cross between camphor basil and dark opal basil. "African blue basil plants are sterile, unable to produce seeds of their own, and can only be propagated by cuttings.
"All parts of the flower, leaves and stems are edible; although some might find the camphor scent too strong for use in the kitchen, the herb reportedly yields a tasty pesto with a 'rich, mellow flavor' and can be used as a seasoning in soups and salads, particularly those featuring tomato, green beans, chicken, etc.," Wikipedia tells us. "The leaves of African blue basil start out purple when young, only growing green as the given leaf grows to its full size, and even then retaining purple veins. Based on other purple basils, the color is from anthocyanins, especially cyanidin-3-(di-p-coumarylglucoside)-5-glucoside, but also other cyanidin-based and peonidin-based compounds."
A final note that Wikipedia relates: It "blooms profusely like an annual, but being sterile can never go to seed. It is also taller than many basil cultivars. These blooms are very good at attracting bees and other pollinators."
Right. "These blooms are very good at attracting bees and other pollinators."
Wikipedia forgot to mention that blooms are "very good at attracting predators," like praying mantids. They go where the bees are, and the bees are in the African blue basil.
Can you find the mantis in the image below?

But have you ever seen a frog's mouth filled with an entire European wasp colony?
No?
Check this out! On Aug. 8, sharp-eyed Adrienne R. Shapiro of Davis spotted a colony of European paper wasps, Polistes dominula, nesting in the mouth of a garden frog statue in The Cannery neighborhood, Davis.
She shared several images with us. In the large image below, "you can see the paper nest inside the mouth," noted husband Art Shapiro, UC Davis distinguished professor in the Department of Evolution and Ecology.
Incredible image! And what a mouthful.
Passersby may think these insects are yellowjackets nesting in the frog statute, but they are not. They are European paper wasps. "The first North American occurrence of P. dominula was reported in Massachusetts in the late 1970s, and by 1995, this species had been documented throughout then northeastern USA," according to Wikipedia. "Behavioral adaptations of P. dominula have allowed it to expand outside its native range and invade the United States and Canada. While most Polistes species in the United States feed only on caterpillars, P. dominula eats many different types of insects."
UC Davis distinguished professor Lynn Kimsey, director of the Bohart Museum of Entomology, says "There are three very different kinds of social wasps that make paper nests: yellowjackets, hornets and paper wasps."
In one of her Fact Sheets on the Bohart website, Kimsey writes: "Although they all belong to the same family of wasps, Vespidae, they build quite different kinds of nests. Paper wasps in the genera Polistes and Mischocyttarus build open-faced nests, where the individual cells are exposed. Hornets and yellowjackets build cells in separate combs that are all enclosed in a paper shell or shroud. Yellow jackets tend to build their nests in cavities. Hornets often create spherical free-hanging nests, but will also build nests in colonies."
Frankly, it's easy to distinguish the European paper wasps from the yellowjackets by the color of their antennae. European paper wasps have orange-tipped antennae while the antennae of the yellow jackets are black. Read what the UC Statewide Integrated Pest Management (UC IPM) says about "Yellowjackets and Other Social Wasps."
Now if a frog statue could talk..."Jumping Jehoshaphat! One more wasp in my mouth and I'll croak!"

It's NOT because they're unnecessary. She supplies them.
“I tell them when they join not to buy bees or equipment because I catch swarms for them and I have a lot of donated equipment including suits of all sizes,” said Ettamarie, widely known as Sonoma County's Queen Bee. “I give the parents and big teenagers the adult suits. It is important for at least one parent to have a suit because they are always there when we open the hives and I try to encourage parents to get involved. That is not hard to do because it isn't unusual for the parent to be the one pushing the child into the project because they want to know more about beekeeping!”
During the past 4-H year, September to June (similar to a traditional school year) she caught 19 swarms in the area and gave 17 to the 4-H'ers.
“I had to replace some colonies when the swarms failed to thrive,” she said. ”These young people are really understanding of all the things that can cause a colony to crash. We do forensics on failed colonies at some meetings. We discuss what can or did go wrong. I am always so pleased to hear them use great bee vocabularies. Even the little ones surprise me by their great questions and responses to my questions! It always puts a smile on my face to see them work with their colonies. Young people seem to be more calm around their bees than most adults. Once in awhile, I have even seen them pet their bees when they land on their gloves or arms.”
A retired 37-year school teacher, a 28-year beekeeper, and a 22-year 4-H beekeeping project leader, Ettamarie is a longtime member, a past president of the Sonoma County Beekeepers' Association (SCBA) and the current newsletter of SCBA's The Monthly Extractor.
Although the 4-H year runs from September to June, beekeeping is a year-around project. “It's a summer endeavor, too, so I do visits to their homes to check on their hives during the summer, of course.”
Teaching youths about bees comes naturally for the retired school teacher. She launched her 4-H beekeeping project in 2000 when her son Lew wanted his daughter, Kasey, “to take beekeeping because he wanted the local honey,” Ettamarie recalled. “Since I had been beekeeping since about 1994 or so they asked me to take on the project as leader. There was no other beekeeping project in the county at that time.” Today there are two in the county, and she generously supplies them with how-to literature.
Ettamarie doesn't follow a 4-H beekeeping manual. “I use an older manual, but to tell you the truth I have just used a bit of this and that together to run the meetings and give the young beekeepers a collection of worksheets that I have found useful,” she said. “For example, one page tells the life cycle and stages with days of the queen's, workers' and drones' eggs, larva and pupa. One page tells which days the workers do each job starting with cleaning house. One page describes diseases. One page shows all the hive parts.”
Of her current students, “two of the families are cousins and they have been in the project for three years. Their grandmother was my grandchildren's dairy project leader years ago so I feel like I am paying her back for all the years she helped them! She has gotten very interested in bees, too!”
One mother enrolled in a free online Pennsylvania State University beekeeping course the first year of the COVID pandemic lockdown. “She is great and has even helped catch one of her daughter's swarms!”
At every meeting, her 4-H'ers examine the bee activity in her observation hive. She also uses her own colonies to teach hive inspection, “and it is good for them to see the differences in each colony. Since I have experienced beekeepers every year, I am able to use them to demonstrate what to do. One of things I love about 4-H is that several older 4-H'ers can get teen leader experience and help the younger ones.”
“I think it is exciting to see young people get so involved with bees,” Ettamarie said. “Most of them stay in the project at least three years or more!”
What fascinates her about bees? "The bees are so fascinating because they work strictly by instinct and as one organism. They are so organized and teach us so much. I love watching how they approach various flowers, some they just land on, some they burrow down into and some they seem to nibble the part they can suck nectar from. I am also fascinated by how they have their favorite flowers. I say some flowers are equivalent to chocolate in my world! I have learned so much about flowers since I started keeping bees. They teach me to open my eyes and pay attention to the world! When my granddaughter and I started off on our trip to Italy this summer, she told me her mother warned her about me. My daughter told her grandma will stop at every flower to see if there is a bee on it and take a picture if she spots one! How well she knows me!"
In 2011, the Sonoma County 4-H Office presented her with the "Friend of 4-H Award" for her Liberty 4-H project leadership in beekeeping and her previous 4-H activities, including leader of sewing and poultry projects, when her children were enrolled in 4-H.
This year the Petaluma resident will be honored as the 2022 recipient of the Youth Ag and Leadership Foundation's 4-H Alumni Recognition Award for her many contributions to Sonoma County 4-H. The event takes place at a barbecue on Sept. 24 at a vineyard in Windsor “and I get a table for 8 at the barbecue!” she said. “My children and their spouses will fill the table!” Her three children are Karen Nau, a preschool teacher; Margie Hebert, a second-grade teacher, and Lew Peterson, an electrician and pilot.
The Petaluma Chamber of Commerce honored her several years ago but the COVID pandemic cancelled the ceremony. “I think I am getting a fat head with all of this recognition but I really love it! I taught for 37 years and didn't get this much appreciation!”
Ettamarie credits husband Ray with introducing her to agriculture. In the late 1960s he purchased 20 head of Angus cattle for their Potter Valley ranch. In 1972 the Petersons moved to their six-acre Petaluma farm, where they raise cows and chickens, grow vegetables, and keep bees. She currently maintains four bee colonies and an observation hive.
"My husband is not a beekeeper and loves to tell my friends beekeeping is addictive and there is a 12-step program to recovery!" Ettarmarie quipped. "He is all talk, of course! He really enjoys the honey and that I have something to keep me busy and happy, besides our six-acre farm and the huge family!"
"None of our children are beekeepers but our son, Lew, has had fun helping me catch swarms," she said. "His daughter, Jessie who is now an ag teacher at Tokay High School in Lodi, went to the Irish Beekeeping School one year and another granddaughter (now a special education teacher in the Santa Rosa School District) went with me another year. A side note about Jessie, she and her husband Lucas Chaves are buying the house in Lodi that is on property that my great-grandparents bought in 1900. The house on the property was built in 1948 by my grandfather for his sister and brother-in-law so I am very excited about that! It was a very small dairy farm originally and Jessie showed dairy cows in 4-H and FFA!"
Ettamarie says that "our California roots are very deep!" Her husband's family settled in Sonoma County in about 1850. "They were ranchers of course. Ray was born on his uncle's prune ranch in Healdsburg."
Always the teacher, Ettamarie takes her observation hive to school and other interested groups “to teach students and adults about bees.”
Beekeeping Manual. And the proposed California 4-H Beekeeping manual that she would love to work on? She would like it dedicated to the late Eric Mussen, Extension apiculturist based in the UC Davis Department of Entomology and Nematology. Mussen freely gave of his time and expertise to beekeepers throughout California, not only during his 1976-2014 career but during his retirement. He died June 3, 2022 at age 78 under hospice care at the family home in Davis.
Ettamarie wrote in the current edition of The Monthly Extractor that although Eric Mussen retired in 2014, he “never really left his job at UC Davis…and was, always ready to answer our questions… We were fortunate to have him almost annually as a speaker at our meetings. His talks were always straight-forward and honest and laced with humor. I remember the year he told us about the new product to fight mites, Check Mite +. This was made with Coumaphos, an organophosphate pesticide that is highly toxic. He told us all the problems. I remember asking him if he would use it and he looked me right in the eyes and said, ‘No!' This is just one example of his integrity.”
They also recalled that Mussen was a co-founder (and six-term president) of the Western Apicultural Society (WAS). “He supported a diverse group of beekeepers and worked hard to give them a speaking platform and have some fun coming together during those yearly gatherings,” they related. ”We will always remember him as a brilliant beekeeping teacher who educated so many of us.”
Pro-Bee. Mussen considered himself “pro-bee,” from helping a 4-H'er with a single colony to large scale commercial operations.
The Mussen family suggests memorial contributions be made to the California State 4-H Beekeeping Program, with a note, "Eric Mussen Memorial Fund." Checks may be made out to the California 4-H Foundation and mailed to:

If you like your insects long, slender and delicate, and resembling a flying neon needle, the damselfly is for you.
Who can resist watching them and photographing them?
The common blue damselfly or Northern Bluet (Enallagma cyathigerum) is as thin as a needle, a jeweled blue needle.
We've seen them hover in our yard, like mini-helicopters--oops, make that "skinny mini" helicopters--and then touch down on a leaf to feast on small insects.
Damselflies share the same order, Odonata, as their larger cousins, the dragonflies. As any entomologist will tell you, damselflies belong to the suborder Zygoptera, and dragonflies, Anisoptera. They are an ancient group, with fossil records showing they existed at least 250 million years ago.
Odonata means "toothed" and Zygoptera means "paired wings."
Damselflies are no "damsels in distress." They're daytime hunters that "consume large quantities of other insects such as flies, mosquitoes and moths and some eat beetles and caterpillars," according to a Texas A&M University (TAMU) website.
Some other facts on the TAMU site:
- In prehistoric times, dragonflies and damselflies were as huge as hawks and were "the largest insects to ever live."
- Worldwide, there are more than 4700 species of Odonata, with Zygoptera accounting for a third fo them
- Males of most damselfly species are brighter-colored than females
- Damselflies neither bite nor sting.
The UC Statewide Integrated Pest Management (UC IPM) describes damselflies this way: "The head is narrow with bulging eyes, long antennae, and tubular-sucking mouthparts. The legs are long and the front pair are slightly swollen with inconspicuous spines. Adults and nymphs can move rapidly when disturbed or stalking prey."
A photography tip: if you spot a damselfly, approach it with your camera already raised. A sudden movement may spook them.
