Honey bees and the Blue Angels...
Honey bees sometimes seem to fly in formation over such plants as flowering artichokes, but their precision--if you could call it that--never matches that of the Blue Angels.
For one, the pollen-packing bees are wobbly and bump into one another. But they always seem to know where they're going and how to get there. They're the pride and joy of the agricultural world as they collect pollen and nectar.
The Blue Angels' flight demonstration squadron is the pride and joy of the U.S. Navy. In fact, their mission is " to showcase the pride and professionalism of the United States Navy and Marine Corps by inspiring a culture of excellence and service to country through flight demonstrations and community outreach."
The Blue Angels' show drew thousands of spectators on Sunday in San Francisco. We watched the aerobatics from the deck on the Flying Fish charter sportsfishing boat. We we all surged with patriotism, excitement and awe as the Blue Angels maneuvered their Hornets into diamond and delta formations, solos, slow passes, barrel rolls and tight turns.
Honey bees engage in their own kind of air show as they carry their pollen and nectar back to the hive. They don't do diamond and delta formations or barrel rolls, but back at the hive, they know how to perform waggle and round dances, making slow passes and tight turns.

The Bohart Museum of Entomology on the UC Davis campus is planning an open house on "How to Be an Entomologist" from 1 to 4 p.m., Saturday, Sept. 27. The insect museum is located in Room 1124 of the Academic Surge building, Crocker Lane, off LaRue Road.
The event is free and open to the public and is family friendly. This is the first of nine open houses during the 2014-15 academic year.
Plans call for a number of UC Davis entomologists to participate--to show and explain their work, said Bohart Museum director Lynn Kimsey, professor of entomology, UC Davis Department of Entomology and Nematology.
"We will have a pinning and butterfly and moth spreading ongoing workshop with Jeff Smith and tips on how to rear insects," said Tabatha Yang, the Bohart Museum's education and outreach coordinator. Smith, an entomologist in Sacramento, is a longtime donor and volunteer at the Bohart.
Representatives from the labs of molecular geneticist Joanna Chiu, assistant professor; bee scientist Brian Johnson, assistant professor; ant specialist Phil Ward, professor; insect demographer James R. Carey, distinguished professor; and integrated pest management specialist Frank Zalom, distinguished professor and current president of the 7000-member Entomological Society of America will share their research.
The Johnson lab will provide a bee observation hive, and Cindy Preto of the Zalom lab will be sharing her research on leafhoppers. The Carey lab will show student-produced videos, including how to make an insect collection, and one-minute entomology presentations (students showcasing an insect in one minute). The Ward lab will be involved in outside activities, demonstrating how to collect ants. Entomology students will be on hand to show visitors how to use collecting devices, including nets, pitfall traps and yellow pans.
Other entomologists may also participate. "There will be a lot going on inside the Bohart and outside the Bohart," Yang said. "It will be very hands-on."
The Bohart Museum, founded by noted entomologist Richard M. Bohart (1913-2007), houses a global collection of nearly eight million specimens and boasts the seventh largest insect collection in North America. It also houses the California Insect Survey, a storehouse of the insect biodiversity. 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 and on major holidays. Admission is free.
The museum's gift shop (on location and online) includes T-shirts, sweatshirts, books, jewelry, insect-collecting equipment and insect-themed candy.
Special attractions include a “live” petting zoo, featuring Madagascar hissing cockroaches, walking sticks and tarantulas. Visitors are invited to hold the insects and photograph them. The newest residents of the petting zoo are Texas Gold-Banded millipedes, Orthoporus ornatus, which are native to many of the southwestern United States, including Texas.
“They're a great addition to the museum's petting zoo,” Kimsey said. “They are very gentle and great for demonstrations of how millipedes walk and how they differ from centipedes.”
Millipede enthusiast Evan White, who does design and communications for the Robert Mondavi Institute for Wine and Food Science, and is a frequent presenter at the Bohart's open houses, recently obtained the arthropods from a collector in Texas. “Texas Gold-Banded millipedes are naive to many of the Southwestern United States, not just Texas,” he said.
Contrary to popular belief, millipedes are not dangerous. “There is much public confusion about the difference between millipedes and centipedes--not because the two look similar, but because the terms are used interchangeably when not connected to a visual,” White said.
He described millipedes as non-venomous, and relatively slow moving, with cylindrical bodies, two pairs of legs per body segment, and herbivorous. “In fact, they are more like decomposers – they do well on rotting vegetation, wood, etc.--the scientific word for is ‘detritivore.' Most millipedes are toxic if consumed, some even secrete a type of cyanide when distressed. The point being: don't lick one.”
In contract, centipedes are venomous, fast-moving insects with large, formidable fangs, and one pair of legs per body segment. “They are highly carnivorous, although some will eat bananas. Go figure. And they are often high-strung and aggressive if provoked.”

It's a glorious day, the first day of spring, and what better time to mark the occasion by visiting the UC Davis Arboretum Teaching Nursery on Garrod Drive?
Mother Earth, a mosaic ceramic sculpture by talented Donna Billick of Davis, co-founder and co-director of the UC Davis Art/Science Fusion Program, overlooks a thriving garden populated with honey bees, butterflies, sweat bees, syrphid flies, and ladybugs.
Today we saw the mournful dusky-wing butterfly (Erynnis tristis), the first of the year. (How ironic a butterfly with such a sad name would be in the garden the first day of spring!) The more colorful painted ladies (Vanessa cardui) arrived earlier this month. (See the Central California butterfly monitoring site of Art Shapiro, distinguished professor of evolution and ecology at UC Davis for more information on butterflies and his research.)
The UC Davis Arboretum Teaching Nursery attracts scores of pollinators with such plants as ceanothus, salvia, California fuchsia, cut-leaf lilac, rosemary, bulbine and Spanish lavender.
Meanwhile, the officials at the teaching nursery are gearing up for their next public plant sales, set for three Saturdays: April 5, April 26 and May 17 from 9 a.m. to 1 p.m. Garden and irrigation experts will offer guidance for what to plant in your garden, including the Arboretum All-Stars, and offer advice on drought-related resources. A plant doctor clinic is also planned. (Members say 10 percent on plant sales.)
While you're browsing through the plants, don't overlook the pollinators! Indeed, they may just nudge you into buying a specific plant...

Who would have thought?
Who would have thought that ants are more closely related to bees than they are to most wasps?
In ground-breaking research to be published Oct. 21 in Current Biology, a team of UC Davis scientists and a colleague from the Sackler Institute for Comparative Genomics, American Museum of Natural History, has found that ants and bees are more genetically related to each other than they are to social wasps such as yellow jackets and paper wasps.
"Despite great interest in the ecology and behavior of these insects, their evolutionary relationships have never been fully clarified," said senior author and noted ant specialist Phil Ward, professor of entomology at UC Davis. "In particular, it has been uncertain how ants—the world’s most successful social insects—are related to bees and wasps. We were able to resolve this question by employing next-generation sequencing technology and advances in bioinformatics. This phylogeny, or evolutionary tree, provides a new framework for understanding the evolution of nesting, feeding and social behavior in Hymenoptera."
The researchers used state-of-the-art genome sequencing and bioinformatics to produce this significant research.
The six-member team: Ward; molecular geneticist and assistant professor Joanna Chiu; honey bee scientist and assistant professor Brian Johnson; doctoral student-researcher Marek Borowiec of the Ward lab; and postdoctoral researcher Joel Atallah of the Johnson lab, all with the UC Davis Department of Entomology and Nematology; and visiting scientist Ernest K. Lee of the Sackler Institute for Comparative Genomics, American Museum of Natural History.
Ants, bees and stinging wasps all belong to the aculeate (stinging) Hymenoptera clade -- the group in which social behavior is most extensively developed.
Said Chiu: “With a phylogeny or evolutionary progression that we think is reliable and robust, we can now start to understand how various morphological and/or behavioral traits evolved in these groups of insects, and even examine the genetic basis of these phenotypic changes.”
Said Johnson, whose lab studies the genetics, behavior, evolution and health of honey bees: "Using transcriptomics we were able to resolve a long standing question regarding the evolutionary relationships between stinging wasps, ants, and bees. We found that ants and bees are more closely related than previously thought. This result should be important for future studies focused on eusocial evolution, as it suggests that morphology may not be a good indicator of evolutionary relatedness in these groups of organisms."
The abstract: "Eusocial behavior has arisen in few animal groups, most notably in the aculeate Hymenoptera, a clade comprising ants, bees, and stinging wasps. Phylogeny is crucial to understanding the evolution of the salient features of these insects, including eusociality. Yet the phylogenetic relationships among the major lineages of aculeate Hymenoptera remain contentious. We address this problem here by generating and analyzing genomic data for a representative series of taxa. We obtain a single well-resolved and strongly supported tree, robust to multiple methods of phylogenetic inference. Apoidea (spheciform wasps and bees) and ants are sister groups, a novel finding that contradicts earlier views that ants are closer to ectoparasitoid wasps. Vespid wasps (paper wasps, yellow jackets, and relatives) are sister to all other aculeates except chrysidoids. Thus, all eusocial species of Hymenoptera are contained within two major groups, characterized by transport of larval provisions and nest construction, likely prerequisites for the evolution of eusociality. These two lineages are interpolated among three other clades of wasps whose species are predominantly ectoparasitoids on concealed hosts, the inferred ancestral condition for aculeates. This phylogeny provides a new framework for exploring the evolution of nesting, feeding, and social behavior within the stinging Hymenoptera."

“I almost wish we were butterflies and liv'd but three summer days--three such days with you I could fill with more delight than fifty common years could ever contain,” wrote John Keats in Bright Star: Love Letters and Poems of John Keats to Fanny Brawne.
"Happiness is a butterfly, which when pursued, is always just beyond your grasp, but which, if you will sit down quietly, may alight upon you," wrote Nathaniel Hawthorne
An Irish blessing reads:
"May the wings of the butterfly kiss the sun
And find your shoulder to light on,
To bring you luck, happiness and riches
Today, tomorrow and beyond."
From time immortal, we humans have depicted butterflies in our art. There's something about the ballet of butterflies that soothes our mind, brightens our spirit, and captures our soul.
So it is with the talented artists exhibiting their work at McCormack Hall during the five-day Solano County Fair, 900 Fairgrounds Drive, Vallejo. The fair opens Wednesday, July 31 and ends Sunday, Aug. 4.
Vallejo resident Yoko Warncke cross-stitched butterflies for her needlework exhibit. Another Vallejo resident, Tina Waycie, crafted a paper butterfly and flowers.
Trudy Molina of Fairfield depicted "The Hungry Caterpillar" in a baby quilt. It's a quilt sure to be treasured. It reminds us of the quote by Richard Buckminster Fuller: "There is nothing in a caterpillar that tells you it's going to be a butterfly."
Vallejoan LaQuita Tummings quilted a beautiful bee, dragonfly and ladybug, so spectacular that you just want to sit and study it.
We watched Gloria Gonzalez, superintendent of the McCormack Hall building and her adult and youth assistants hang many of the displays. They're involved in the Sherwood Forest 4-H Club, Vallejo, throughout the year, but in the summer when the Solano County Fair rolls around, they're at McCormack Hall accepting entries, recording results and displaying the work.
Insect art is just a small part of the displays in McCormack Hall. You'll see photography, collections, table settings, clothing, baked goods, jams and jellies, and even some farm equipment.
It all ties in with the fair theme, "Home Grown Fun."
