You've heard of the California Bear Flag, the one with the grizzly bear" right?  It's lettered with "California Republic."

But have you heard of the "other" bear flag that's on a hooded sweatshirt at the Bohart Museum of Entomology at the University of California, Davis? It's lettered with "Bohart Republic."

The Bohart flag features a water bear or tardigrade, the creative work of UC Davis entomologist/artist Charlotte Herbert Alberts.

Besides living on the Bohart sweatshirts, the tardigrade is a microscopic, water-dwelling animal that lives just about everywhere:  "from the mountaintops to the deep sea and mud volcanoes; from tropical rain forests to the Antarctic," according to Wikipedia.  German zoologist Johann August Ephraim Goeze, who first described them in 1773, called them "little water bears."

The name stuck. "Water bears."

"Tardigrades are among the most resilient known animals, with individual species able to survive extreme conditions that would be rapidly fatal to nearly all other known life forms, such as exposure to extreme temperatures, extreme pressures (both high and low), air deprivation, radiation, dehydration, and starvation," Wikipedia says. "Tardigrades have even survived exposure to outer space. About 1,150 known species form the phylum Tardigrada, a part of the superphylum Ecdysozoa. The group includes fossils dating from 530 million years ago, in the Cambrian period."

Alberts is a doctoral candidate in entomology who studies with Lynn Kimsey, director of the Bohart Museum and a UC Davis professor of entomology.

How did she get the idea? "I came up with the tardigrade flag idea in my sleep!" she said. "The next morning I told Lynn and she loved it."

Then Alberts and Kimsey conferred with Tabatha Yang, education and outreach coordinator, and Bohart associate Fran Keller, assistant professor at Folsom Lake College and a UC Davis alumnus (she holds a doctorate in entomology) "to figure out the details"--like the entomologist holding a net and riding the tardigrade, and the name, "Bohart Republic."

"The entomologist is no one in particular," Alberts said, "but she's a female because I think it is important to encourage more women into the field of entomology."

"So far, the reactions have all been super positive!" she commented. "My family and friends are all asking for one!"

The water bear hoodies were also a big hit Saturday, Feb. 16 at the Bohart Museum during the eighth annual campuswide Biodiversity Museum Day.  The gift shop buzzed with sales. Specifics? The hoodies come in three colors--red, gray and black and in sizes ranging from extra small to extra extra large.

Located in Room 1124 of the Academic Surge Building on Crocker Lane, the Bohart Museum, home of a global collection of some eight million insect specimens, is open to the public from 9 a.m. to noon and from 1 p.m. to 5 p.m., Monday through Thursday.

A bright blue stuffed animal tardigrade in the gift shop also sells well.

"I do not have a stuffed tardigrade but often gaze fondly at the ones for sale at the Bohart," Alberts commented. "I would love to adopt one... but am worried that our sweet puppy will think it is for him."

As for the real tardigrades, they have always fascinated her, especially "their ability to survive in any environment--even space!"

Tardigrade enthusiasts love them more than they can "bear."

Identification. Collaboration. Camaraderie.

The scientists and butterfly/moth enthusiasts who gathered Saturday, Feb. 9 for the Northern California Lepidoptera  Society meeting in the Bohart Museum of Entomology at the University of California, Davis, did all that: identify specimens and engage in collaboration and camaraderie.

They ranged from those early in their career, to mid-point, to the height of their career, to retired.

The group meets for a mid-winter gathering once a year, alternating between the Bohart Museum of Entomology at UC Davis and the Essig Museum of Entomology at UC Berkeley.

Senior museum scientist Steve Heydon, Bohart associate John "Moth Man" DeBenedictis; and Jeff Smith, curator of the butterfly/moth section at the Bohart hosted the event, assisted by Lynn Kimsey, director of the Bohart Museum and Bohart associate and naturalist Greg Kareofelas. 

In their meeting notice, Heydon, DeBenedictis and Smith noted that those attending could bring specimens, photos, PowerPoint presentations "or slides from collecting trips and tales of collecting triumphs to share with others
and that "attending lepidopterists may be able to help you identify specimens and the museum collection will be open for yoour inspection."

Christopher Jason, a recent UC Davis graduate in environmental science, was there with his collection. In March he will head to Washington State University, the Vancouver, campus, to work as a technician in the lab of conservation biologist/associate professor Cheryl Schultz, who researches at-risk butterflies in Pacific Northwest Prariries. Or, as Schultz. writes on her website: "Human-caused changes in the earth's ecosystems are responsible for the decline and extinction of the world's biological diversity. In the Conservation Biology Research Group, we study the ecology of at-risk species in response to key drivers: habitat loss, habitat fragmentation, habitat degradation, invasive species, alteration of ecosystem process, and global climate change. Using a population-ecology lens, we use field and quantitative methods to address pivotal ecological questions. We seek to understand the relative contributions of individual, population and landscape-level processes to the population viability of endangered species as these processes interface with realistic conservation interventions. Our work largely uses at-risk butterflies in Pacific Northwest Prairies as a model system to address fundamental ecological questions while simultaneously tackling focal questions to guide on-the-ground practice."

Retired public health entomologist and Bohart associate Dick Meyer of Bakersfield, known as "the mosquito guy," was there. He recently retired as assistant manager of the Orange County Vector Control Agency. He did not bring any of his collection, but he did tell us that he has 225 drawers of insects at home, including 71 drawers of butterflies. "Did you know that the highest diversity of butterflies in the country is in Kern County?" he asked. Meyer, who holds a doctorate in entomology, studied with major professor Richard M. Bohart Jr., for whom the Bohart Museum is named.

Among those participating:

• Bohart associate Jerry Powell, emeritus director of the Essig Museum, and co-author of California Insects.
• Marc Epstein, senior insect biosystematist for the California Department of Food and Agriculture and author of the book, Moths, Myths and Mosquitoes: the Eccentric life of Harrison G. Dyer Jr.

• And many more...

At the last gathering in the Bohart, Kelly Richers, who compiles the California Moth Specimen Database, maintained at the Essig Museum since 1996 as a resource to better survey and understand California moths, said of the systematists:  "We're a dying breed." 

This year self-described "aspiring entomologist" Madison Cunha of Modesto attended with her mother, Christine Cunha. True to her love of insects, Madison wore a dress adorned with a beetle pattern.

Scientists say that 180,000 species of the Lepidoptera are described, in 126 families and 46 superfamilies.

"The Lepidoptera are among the most successful groups of insects. They are found on all continents, except Antarctica, and inhabit all terrestrial habitats ranging from desert to rainforest, from lowland grasslands to mountain plateaus, but almost always associated with higher plants, especially angiosperms (flowering plants). Among the most northern dwelling species of butterflies and moths is the Arctic Apollo (Parnassius arcticus), which is found in the Arctic Circle in northeastern Yakutia, at an altitude of 1500 m above sea level. In the Himalayas, various Apollo species such as Parnassius epaphus have been recorded to occur up to an altitude of 6,000 miles above sea level."--Wikipedia.

Happy Presidents' Day.

It's day we honor not only George Washington and Abraham Lincoln but all the men (no women yet!) who have served as President of the United States.

"The federal holiday honoring Washington was originally implemented by an Act of Congress in 1879 for government offices in Washington  and expanded in 1885 to include all federal offices," according to Wikipedia. "As the first federal holiday to honor an American president, the holiday was celebrated on Washington's birthday under the Gregorian calendar, Feb. 22. On Jan. 1, 1971, the federal holiday was shifted to the third Monday in February by the Uniform Monday Holiday Act. This places it between February 15 and 21, which makes 'Washington's Birthday' something of a misnomer, since it never occurs on Washington's actual birthday, Feb. 22."

"A rough analog of this phenomenon can be seen in Commonwealth realms, where the reigning monarch's official birthday is celebrated without regard to their actual date of birth."

There you have it.

And speaking of monarchs and Presidents' Day, it's a good time to post a monarch on the American flag.   Danaus plexippus reigns supreme in the world of butterflies, in that it's arguably the most recognized butterfly.

The embattled monarch--some folks want to see it listed as threatened or endangered--will be the subject of a session hosted by the Environmental Defense Fund on Feb. 28 at the University of California, Davis. It's by invitation only. But one of the speakers is Art Shapiro, UC Davis distinguished professor of evolution and ecology.

Shapiro, who has monitored the entire butterfly faunas (including monarchs) at 10 locations along I-80 coordinator for more than four decades, just published a commentary in the Davis Enterprise headlined "So the Monarch Is Endangered--Now What?"

He began with "So the monarch butterfly is in trouble and various folks, including the editorial board of the Sacramento Bee, want California or the United States, or both, to declare it endangered or at least threatened (Bee editorial Feb. 5). Great, then what?

"The fact is, nobody can answer that question competently."

"There is no disputing the facts: Monarch butterfly populations in California have dropped catastrophically," he wrote. "Based on counts of adults overwintering along the coast, numbers have dropped from some 4.5 million in the 1980s to a mere 28,429 this year. At one site, Bolinas, numbers dropped 90 percent in one year from 12,360 in 2017 to 1,256 this year."

"But the decline has not been linear or monotonic, and it is very poorly understood."

He noted: "Conservation organizations are promoting lists of things private citizens and organizations can do to help “save the monarch.” The most-often-repeated one is to plant milkweed, its larval host plant. But there is absolutely no evidence that there is any milkweed shortage in California, let alone that such a shortage is driving monarch declines."

Shapiro went on to write that "there are huge holes in our knowledge of basic monarch biology, and those translate into our inability to say why monarchs are in decline."

Shapiro noted in his commentary that "We have been stuck with using the winter censuses, which are easy to generate, as our measure of population size. But the winter numbers are the sum of everything that happened during the year, which is hidden from our view except very locally. One can do statistical analyses with them and they will give you some kind of an answer, but will it tell us anything used in interpreting reality?"

"The point of giving species protection under Endangered Species legislation is to provide a legal umbrella to encourage actions that will promote species recovery. Most endangered species have discrete populations and their critical habitat and resources can thus be protected. The monarch is different. There is no point in declaring it threatened or endangered if that, like planting milkweed, is just a feel-good action unlikely to translate into any benefit to the species."

As for the meeting at UC Davis on Feb. 28, "its first order of business," Shapiro believes, "should be to decide what we need to know that we don't know in order to take meaningful action on the monarch (and by extension, to help the rest of our imperiled butterfly fauna)."

Stay tuned.

Tardigrades, also known as the water bears, are microscopic animals but they're not microscopic any more!

They're featured prominently on the newly available Bohart Museum of Entomology hooded sweatshirts, the work of artist Charlotte Herbert Alberts and designer Fran Keller.

Tardigrades can survive in many extreme conditions, including space, and they're sure to survive in the Bohart--unless they're all gone soon.

Available in red, gray and black, from sizes extra small to extra extra large, they'll be offered in the Bohart Museum gift shop during the UC Davis Biodiversity Museum Day on Saturday, Feb. 16. Proceeds from the sales benefit the insect museum's educational activities.

The artist? Charlotte Herbert Alberts, an entomology doctoral candidate who studies Asilidae (Assassin flies) with her major professor, Lynn Kimsey,   director of the Bohart and UC Davis professor of entomology.  Alberts cleverly drew a "Bohart Republic" water bear flag, a take-off of the California Bear Flag, except hers features an entomologist, insect net in hand, riding a huge tardigrade.

The front features a tardigrade face inside a Bohart logo, a design by Fran Keller, an assistant professor at Folsom Lake College. She received her doctorate in entomology from UC Davis, studying with Kimsey and designed many of the shirts, sweatshirts and posters in the Bohart Museum's gift shop.
