The UC Davis Department of Entomology and Nematology and the Bohart Museum of Entomology will be participating in the virtual 107th annual UC Davis Picnic Day on Saturday, April 17, a traditional event being held untraditionally this year due to the COVID-19 pandemic.
The entomological events will include cockroach racing and a series of talks. Among them: Bohart Museum associate and natural historian Greg Kareofelas will present a pre-recorded video on Gulf Fritillary butterflies and entomologist Jeff Smith, the Bohart's volunteer curator of the Lepidoptera collection, will deliver a live Zoom talk on butterfly and moth mimicry from 1 to 2 p.m.
Said Smith: "For my presentation on mimicry within Lepidoptera, it will briefly mention camouflage and spend most of the time on mimicry for defense-- mimics of toxic or distasteful species, mimicry using odors or sounds, mimics of snakes or spiders, and mimics of non-food materials such as bird feces."
More events--and the schedule--are pending.
The Bohart Museum, temporarily closed, is located in Room 1124 of the Academic Surge Building on Crocker Lane. Directed by Professor Lynn Kimsey, the Bohart Museum includes nearly eight million insect specimens, a live "petting zoo" (Madagascar hissing cockroaches, stick insects and tarantulas) and an online gift shop stocked with insect-themed t-shirts, jewelry, hoodies, books, posters and more.
Discovering Silver Linings
This year's theme is “Discovering Silver Linings.” Despite all that has happened this year, the UC Davis community has continued to find silver linings everywhere, the Picnic Day officials reported on their website. "Our campus always strives to inspire hope and works towards a better and brighter tomorrow."
Last year's in-person events also were canceled and some virtual events took place.
"This long-standing campus tradition began in 1909 when the University Farm invited the surrounding community to view their new dairy barn. Two thousand visitors attended, bringing picnics to complement the coffee, cream, and sugar provided by the University. Following the success of the 1909 picnic, the faculty of the University Farm continued to plan and sponsor the event until a student committee took over the task in 1912. Through the years of Picnic Day history, the event has only been canceled five times. In 1924, an outbreak of hoof-and-mouth disease among the cowherds caused the first cancellation. In 1938, delayed construction of the gymnasium, which was needed to accommodate the ever-increasing number of participants, led to a second cancellation. During World War II, the Army Signal Corps controlled the campus, and Picnic Day disappeared from 1943 to 1945. Since 1946, Picnic Day has been growing strong and now boasts an annual attendance of more than 70,000 people. This year, there will be more than 200 events on campus and an estimated 75,000 visitors attending this special event. Since 1959, the parade was extended to include downtown Davis to celebrate the fact that Davis became a separate UC campus and not just the Farm School for UC Berkeley."

A newly installed water bear or tardigrade sculpture at the Bohart Museum of Entomology, University of California, Davis, promises not only to be a cuddly campus landmark but it may be the world's largest—and only—sculpture of its kind.
The huge sculpture, located in front of the Academic Surge Building on Crocker Lane, anchors the entrance to the Bohart Museum, which houses one of the world's largest tardigrade collections.
“I'm not aware of any other statue of a water bear anywhere,” said Lynn Kimsey, director of the Bohart Museum and a UC Davis professor of entomology.
A crew installed the concrete sculpture, the work of artist Solomon Bassoff of Faducci LLC, North San Juan, Calif., at 7 a.m. Feb. 3 in a half-hour project.
It weighs 2,112 pounds and measures six feet long and nearly three feet high. In real life, the water bear is microscopic. The adults usually range from 0.3 to 0.5 mm in length.
“I was so excited to see it on the truck,” said Kimsey, who launched the project via a GoFundMe account two years ago. “Looking at pictures is one thing but the real thing was awesome and it's really fun to see it in front of the building. The whole business only took about half an hour. They had to first move two concrete garbage containers, which probably weigh 1,000 pounds each.”
“The installation is complete except for signage,” she said. “We'll be putting up a plaque explaining what it is and major donors. It stands to get even more over the next three years.”
Bassoff, who creates sculptures in concrete, steel and mosaic from his studio in the Sierra foothills, said he sculpted the tardigrade with a “steel armature (coated to prevent corrosion), pigmented hand sculpted concrete and bronze claws. It was fun and amazing to learn more about this amazing creature.”
They belong to their own phylum, the Tardigrada (meaning "slow steppers"), with more than 1,500 described species. "Tardigrades can survive high pressures of more than 1,200 atmospheres found in the bottom of the abyss," Kimsey said. "They can tolerate 1,000 times more ionizing radiation than other animals."
The barrel-shaped creature with eight pudgy legs inspired German zoologist Johann August Ephraim Goeze (1731-1793) to describe them as "kleiner Wasserbär," or "little water bears."
Tardigrades are easiest to find on lichens and mosses, Kimsey says, but they can also be found on beaches, in the subtidal zone, freshwater sediments, soil, hot springs and even on barnacles. They've been found "high in the Himalayas to down in the deep sea and even in the interior of Antarctica.”
They mostly feed on plants or bacteria "but some are predators on smaller tardigrades," Kimsey related. “They use the stylets in their tubular mouth (snout) to pierce "individual plant or bacterial ells or small invertebrates."
Why is the water bear so indestructible? In research published in 2016, geneticist Takekazu Kunieda and his colleagues from the University of Tokyo found that it expresses a tardigrade-specific protein that binds itself to DNA. This acts like a "shield against x-ray radiation, preventing the DNA from snapping apart," according to an article published in Gizmodo.
Kimsey credited former Bohart Museum scientist Bob Schuster with launching and compiling the current tardigrade collection. The Bohart is now gearing up for more specimens. Kimsey is part of a three-year, $256,849 National Science Foundation research grant, “Cross Departmental Development of an Automated Species Identification System for the Phylum Tardigrada Found on Birds,” awarded to her and five faculty members from Baker University, Baldwin City, Kansas. All tardigrades collected by Baker University's faculty and students will find a new home in the Bohart Museum.
“Our part in all this is to act as a repository for all of the specimens collected,” Kimsey said. “We have one of the four largest collections of tardigrades in the world.”
Solomon Basshoff and fellow artist Domenica Mottarella, who formed Faducci in 2002, are known throughout the country for their whimsical emotive sculptures, commissioned for public art installations and private collections. Locally, they created the Davis Central Park Gardens' children's play sculpture, “Bellapede.” Installed in 2010, it is shaped like a monarch caterpillar.
Just like “Bellapede,” the water bear sculpture should be a magnet for children and their families," Kimsey said. "Tardigrades are really popular with kids in part because of their representation in the movies Ant-Man and Ant-Man and the Wasp, Star Trek and Family Guy."
The Bohart Museum, located in Room 1124 of the Academic Surge Building, houses a global collection of nearly eight million insect specimens. It also houses a live “petting zoo” of Madagascar hissing cockroaches, stick insects and tarantulas, as well as a year-around—and now online--gift shop. The insect museum is currently closed to the public due to COVID-19 pandemic precautions.
But the tardigrade sculpture beckons all.

It will not be a day--it will be a month, the month of February.
It will not be a walk-around event--it will be virtual.
Traditionally billed as a “free, educational event for the community where visitors get to meet and talk with UC Davis scientists "and see amazing objects and organisms from the world around us,” it's a science-based event showcasing the diversity of life, according to Biodiversity Museum Day coordinator Tabatha Yang, education and outreach coordinator for the Bohart Museum of Entomology.
Over the last nine years, it took place the Saturday of Presidents' Day weekend. Last year more than 4000 attended.
Information on the event is being posted on the UC Davis Biodiversity Museum Day website as plans unfold. The 12 museums or collections participating in the virtual program this year via Zoom webinars, Facebook programs and YouTube will be:
- Anthropology Museum
- Arboretum and Public Garden
- Bohart Museum of Entomology
- Botanical Conservatory
- California Raptor Center
- Center for Plant Diversity
- Häagen-Dazs Honey Bee Haven
- Nematode Collection
- Marine Invertebrate Collection
- Museum of Wildlife and Fish Biology
- Paleontology Collection
- Phaff Yeast Culture Collection
The live talks and demonstrations and pre-recorded talks and activities are being posted on the Biodiversity Museum Day/Month website.
Live talks will encompass such topics as heliconius butterflies, bees and gardens, orchid bees, plants in the Botanical Conservatory, Asian giant hornets (aka murder hornets), ants, yeasts, mammal specimen preparations and raptors.
Pre-recorded programs will cover bee diversity, millipedes, herbariums and marine life, as well as how to make a bee condo and how to prepare insects (spread the wings of butterflies and moths) for display, among other subjects.
All participating museums and collections have active education and outreach programs, Yang said, but the collections are not always accessible to the public. More information is pending on the website at http://biodiversitymuseumday.edu, and on social media, including Facebook and Twitter, @BioDivDay.
The UC Biodiversity Museum Day/Month program is participating in Crowdfund UC Davis "where alumni, students, parents and friends can make donations to support innovative projects that propel student engagement, new research discoveries, and efforts to expand UC Davis impact on California and the world." The funding program will continue through the end of February.

Every year the UC Davis Insect Ecology group lists its favorite papers, said community ecologist Rachel Vannette of the UC Davis Department of Entomology and Nematology. She listed the group's favorites on her lab website and also listed her lab's picks.
Menke, who received his doctorate in entomology from UC Davis in 1965, studying with Professor Richard Bohart (for whom the Bohart Museum of Entomology is named), is a noted expert on wasps. Ammophila are sometimes called "thread-waisted wasps" or "sand wasps" but neither is definitive. Ammophila comes from the Greek "sand lover." (See BugGuide.net for images.)
A partial abstract of the Menke publication:
"The North and Central American species of Ammophila are described and a key provided for their identification. Sixty-nine species are recognized, of which 62 are known from North America. The other seven are known only from Mexico. Four new species are described, hallelujah from northeastern California, linda from southern California, mexica and zapoteca from south central Mexico."
Mencke is also the co-author of "Funny or Curious Zoological Names." Included in the list: he named a species of Australian wasp, "Aha ha," as a joke. From Wikipedia: "Menke described several years after its discovery how, when he received a package from a colleague containing insect specimens, he exclaimed 'Aha, a new genus,' with fellow entomologist Eric Grissell responding "ha" doubtfully. The name of the insect is commonly found in lists of bizarre scientific names. The name was also used as the vehicle registration plate of Menke's car, "AHA HA."
