The summer edition includes Bernardo Niño's article, "Educational Apiary at UC Davis Is A-Buzz."
"After much preparation and planning, we finally established an educational apiary here at the UC Davis Bee Facility," he wrote. "The main goal of this apiary is to provide beekeepers of all levels with an opportunity to experience a variety of hive types. We have been teaching beekeeping courses for awhile now and we always get asked about hives other than Langstroth. So we have finally made the first step towards providing a comprehensive demonstration of the different ways to keep honey bees. If you were to come by the apiary right now, you would get a chance to see a Kenyan Top Bar hive, Warré hive, Langstroth hive, and even a Langstroth hive modified with Flow™ Hive frames. Next season we are excited to add the Hungarian Rotating hive, as well as plastic and polystyrene hives." Bernardo Niño also offers a quick review of what these hives are.

If you engage in a mini-monarch conservation project, you know the joy of watching the egg-caterpillar-chrysalis-adult transformation. It's one of Nature's miracles.
Then when you release the monarchs and watch them soar high, awkwardly fluttering their wings in new-found freedom, that's another high.
But there comes a day when you realize that Nature isn't perfect--not that you ever thought it was or ever will be.
In fact, Nature can be a little cruel.
Take the case of several caterpillars we reared in an enclosed habitat to protect them from predators. The 'cats ate the milkweed, and then, they formed chrysalids, just like they're supposed to do. Perfectly formed green-jade chrysalids dotted in gold.
They all looked normal, except one. Apparently a very hungry caterpillar chomped on one of the chrysalids instead of its milkweed. It knawed and knashed until it cratered it.
"This is it!" we figured. All done. No more left to eclose. But today, a monarch eclosed from the damaged chrysalis. A monarch with a deformed wing.
It was a girl. It still is.
We placed her on a broadleaf milkweed (Asclepias speciosa), where she sunned herself and warmed her flight muscles--flight muscles she'll never use because she cannot fly. She sipped some sugar-water and a chunk of juicy watermelon.
She may even attract a mate and give us the next generation.
Maybe. Maybe not.
Nature is not always nice.

And then one morning you see a moth on your blanket flower (Gaillardia). Hmm...
What is it? The moth (below) is "Heliothis virescens, the tobacco budworm, adult," said Lepitopteran expert Art Shapiro, UC Davis distinguished professor of evolution and ecology. "The species is a seasonal immigrant from the south. There is a sibling species, H. subflexa, that is quite rare and feeds only on ground cherry (genus Physalis, Solanaceae).
Like to learn more about moths? Statewide, nationwide and worldwide?
The Bohart Museum of Entomology at the University of California, Davis, will celebrate Moth Night at its open house from 8 to 11 p.m., Saturday, July 30. The theme: "Celebrate Moths!"
Activities, free and open to the public, will take place inside the museum, located in Room 1124 of the Academic Surge Building on Crocker Lane, and outside the building where black lighting will be set up to observe and collect moths and other insects.
Entomology graduate student Jessica Gillung will participate, "so there will be an entomologist fluent in Spanish and Portuguese on site," said Tabatha Yang, the Bohart Museum's education and outreach coordinator.
Visitors are invited to view the Bohart Museum's vast collection of worldwide moth specimens and participate in family friendly craft activities featuring a moth motif. Scientists will explain how to differentiate a moth from a butterfly. Free hot chocolate will be served.
The event is in keeping with International Moth Week: Exploring Nighttime Nature, July 23-31, a citizen science project celebrating moths and biodiversity. The annual event is held the last week of July.
Moths continue to attract the attention of the entomological world and other curious persons. Scientists estimate that there may be more than 500,000 moth species in the world. They range in size from a pinhead to as large as an adult's hand. Most moths are nocturnal, but some fly during the day, as butterflies do.
The Bohart Museum, directed by Lynn Kimsey, professor of entomology at UC Davis, is a world-renowned insect museum that houses a global collection of nearly 8 million specimens. It also maintains a live “petting zoo,” featuring walking sticks, Madagascar hissing cockroaches and tarantulas. A gift shop, open year around, includes T-shirts, sweatshirts, books, jewelry, posters, insect-collecting equipment and insect-themed candy.
The Bohart Museum's regular hours are from 9 a.m. to noon and 1 to 5 p.m. Mondays through Thursdays. The museum is closed to the public on Fridays, Saturdays and Sundays and on major holidays. Admission is free. More information on the Bohart Museum is available by contacting (530) 752-0493 or bmuseum@ucdavis.edu
Tobacco Budworm
Access the UC Statewide Integrated Pest Management (UC IPM) website if you want to learn more about the tobacco budworm, which, in caterpillar stage, is a field crop pest of tobacco, alfalfa, clover, cotton, soybean and flax. And also attacks many of the plants in your vegetable garden and flower bed. Vegetable garden: cantaloupe, pea, pepper, lettuce, squash, tomato and more. Flower bed: geraniums, petunias, mallow, marigold, zinnia, snapdragon, zinnia and more. If you can't distinguish the larva of a tobacco budworm and cabbage looper from a variegated cutworm or a beet armworm, check out this UC IPM page. Then, to glean more information, search for "Tobacco Budworm" or "Heliothis virescens" on the UC IPM site.

Yes, bugged.
And you won't want to miss it.
If you head over to the 69th annual Solano County Fair, 900 Fairgrounds Drive, Vallejo, between now and Sunday, July 31, you'll see lots of bees, butterflies, lady beetles, dragonflies, ants and other insects in McCormack Hall. They're depicted in photos and drawings, and on display boards, quilts, cakes, muffins, China plate paintings and more.
Gloria Gonzalez, superintendent of McCormack Hall, and her crew assembled the last of the displays earlier this week, just in time for the opening on Wednesday, July 27. The fair is open weekdays until 11 p.m., and on Saturday and Sunday, July 30-31, from noon to 11 p.m.
Fairs are educational, informative, and entertaining, and the Solano County Fair, launched in 1949, is no exception. This year's theme is "Play It Again, Solano!"
But, back to the insects. Most of the exhibits in McCormack, of course, do not showcase insects, but many do! And they are amazing!
Have you ever seen a honey bee on a rock? Andrew Donato of Vallejo, has. In fact, he painted a bee on a rock and entered it in the 9-10 age graphic arts category. It's a winner!
Lexi Haddon Mendes of the Vaca Valley 4-H Club, Vacaville, entered a decorated cake, "Flowers and Bees," in her age division, 9-10. She knows bees; she's a beekeeper and her father heads the club's beekeeping project.
Madeline Giron of Benicia entered muffins decorated with colorful ladybugs, aka lady beetles, in her 11-13 age division. Judges said "Yum!" and "Beautiful!" and "Blue Ribbon!"
Joseph Garrett of Fairfield entered several mounted insect specimens--along with a wolf spider (spiders are not insects)--in the science project division, ages 5-8. Is Joseph an entomologist-to-be?
The work of the adults is also incredible!
- Laquita Cumings of Rodeo entered a quilt of the most colorful butterflies you've ever seen. Best of show!
- Kim English of Fairfield entered a "Dresden design" China painting, adorned with flowers, butterflies and a bee.
- Celia Weller of American Canyon crafted a machine-quilted wall hanging adorned with flowers and an exotic butterfly not found in nature--but found at McCormack Hall.
- Beverly O'Hara of Benicia appliqued a quilt with ants and called it "Ant-titude." Clever! It features ants enjoying a picnic. What's a picnic without ants?
- Anita Jessop of Benicia imagined a field of flowers, and quilted a "Sunny Field of Flowers" wall hanging, complete with a hummingbird and dragonflies.
- Laura Ryan of Benicia entered a fan needlepoint anchored with a delightful blue butterfly. Reminds us of the blue morpho!
Those are just some of the prize-winning exhibits by youth and adults displayed at McCormack Hall. Be sure to check out the other buildings as well for an overall look at what the fair offers. The fair ends on Sunday, July 31 at 11 p.m.
Gloria Gonzalez, a longtime 4-H volunteer, has worked on the McCormack Hall displays for 11 years and has served as the superintendent for three years. She's the community leader of the Sherwood Forest 4-H Club, Vallejo, a position she's held for eight years.
The veteran 4-H adult volunteer has served as a project leader in the Sherwood Forest 4-H Club for 18 years. Many of the folks who crew McCormack Hall are also 4-H'ers, including Sharon Payne, a past president of the Solano County 4-H Leaders' Council; and longtime 4-H'ers turned leaders, Angelina Gonzalez and Julianna Payne, all of the Sherwood Forest 4-H Club.

Sometimes caregivers, including grandparents, aunts, uncles, cousins and neighbors, take photos of babies to show "proof of life." They post them for the parents to see, admire and confirm.
It's delightful to see images of your offspring while you're on vacation, on a business trip, or just out and about.
Same with monarch caterpillars. "Monarch Moms" and "Monarch Dads" take "proof-of-life" photos.
Often we'll see a hungry monarch caterpillar chomping and chewing and gorging on milkweed. It's a pretty sight, these chunky white caterpillars banded in yellow and black doing what they do best--eating. Some day they'll form a "J" and then a jade-green chrysalis rimmed with gold. And then--voila!--an adult monarch will eclose.
Some day, but maybe not.
A predator may nail them.
We recently noticed a Missing-in-Action caterpillar from our showy milkweed, Asciepias speciosa, and a quite contented Western scrub jay looking like the cat that ate the canary, or the scrub jay that ate the 'cat. Note that the jays nest in our trees, and to nourish them, we feed them seeds year-around in the birdfeeder.
The birdfeeder, however, happens to be located right next to the 8-foot showy milkweed where monarchs lay their eggs.
Jays apparently like a varied diet. Like a fat juicy worm (to them). Yum? Not yum. It does not taste good. Species in the genus Asclepias produce the toxic cardiac glycosides and this helps protect the caterpillars from predators. Although they don't taste good, they will still eat a few.
The photos below are proof of life of one hungry, thriving caterpillar. The next day? Gone. It became a bird's dinner.
But not its sibling caterpillar. We rescued it and fed it and watched it form a chrysalis. Soon an adult monarch butterfly wlll eclose. This one will be "proof of life."
