Don't head over to the Bohart Museum of Entomology in the Academic Surge Building on Crocker Lane on Saturday, April 20 during the 110th annual UC Davis Picnic Day.
Why?
It will be closed.
The Bohart Museum, part of the UC Davis Department of Entomology and Nematology (ENT), will be staffing a pop-up tent from noon to 4 p.m. in front of Briggs Hall, home of the department.
That means all the "bug" displays at the 2024 UC Picnic Day will be at one place: Briggs Hall. The Bohart has provided a QR code and the location:
https://maps.app.goo.gl/DLBmhLuEnP1rWjn67.
Tabatha Yang, education and outreach coordinator, says the Bohart Museum is planning four areas of interest:
- The "Oh, my drawers," (California arachnids and wing diversity showcasing cicadas and California dogface butterflies.
- Petting zoo of live insects (thorny sticks), which attendees can hold and photograph. Also shown will be a cicada nymph (from retired Bohart senior museum scientist Steve Heydon) and horntail caterpillars from UC Davis biology lab manager and UC Davis alumna Ivana Li.
- A Bohart poster giveaway--California dogface butterflies.
- A dogface butterfly face banner where attendees can pose for photos
The California dogface butterfly, Zerene eurydice, is California's state insect, as authorized by the State Legislature in 1972. The butterfly is found only in California, from the foothills of the Sierra Nevada to the Coast Ranges and from Sonoma south to San Diego. Its most prevalent habitat is in Auburn at the Placer Land Trust's private conservation site (which the public can see through specially guided tours). Why is it there? Because its larval host plant, false indigo (Amorpha californica) thrives there.
The male, which sports a yellow silhouette of a dog's head on its wings, is known as "the flying pansy." The female is mostly solid yellow except for a single black spot on its upper wings.
Kareofelas serves as a docent or volunteer tour guide for the Placer Land Trust's dogface butterfly site. He has reared--and photographed--a dogface butterfly from egg to adult. And he's also grown false indigo.
The posters to be given away Saturday--until gone--are the work of Kareofelas and Keller and depict the male and female butterfly.
Theme of the Bohart Museum's Picnic Day display is "Bonding with the Bohart," in reference to Professor Jason Bond, who succeeded UC Davis distinguished professor emerita Lynn Kimsey as director on Feb. 1. Kimsey served 34 years as the director. Although officially retired from the university, she continues to serve as a researcher, and as the executive director of the Bohart Museum Society and editor of the newsletter. Bond is the Evert and Marion Schlinger Endowed Chair of the Department of Entomology and Nematology, and the associate dean, UC Davis College of Agricultural and Environmental Sciences. He also serves as president-elect of the American Arachnological Society.
In addition to the Bohart Museum displays, the entomological events at Briggs Hall will include:
Bug Doctor
Briggs Hall Entryway
Graduate students will answer questions about insects. What's that bug? Attendees are encouraged to bring an insect or photo for identification.
Cockroach Races
Front of Briggs Hall
American cockroaches, Periplaneta americana, from Bob Kimsey's forensic lab, race on a specially made track, while roach fans cheer for their favorites. (Sometimes the athletes are named for faculty, friends or bystanders.
Medical Entomology
122 Briggs Hall
Carla-Cristina "CC" Melo Edwards of the Geoffrey Attardo lab is coordinating the medical entomology display. Her research focuses on investigating the physiological mechanisms underlying pyrethroid resistance in Aedes aegypti (the yellow fever mosquito).
Diversity of Arachnids
122 Briggs Hall
Doctoral student Emma Jochim of the Jason Bond lab is coordinating an exhibit she created last year to display the diversity of arachnids, such as vinegaroons, whip spiders, tarantulas, and scorpions. "We'll have live animals and fact sheets that will give a general overview of their diversity, behavior, and habitat," Jochim said. "I'll also bring some curated specimens to show what goes into creating a scientific collection and talk about why collections are important for understanding biodiversity. "
Maggot Art
Briggs Courtyard
Artists--children and adults alike--create maggot art by dipping a live maggot into water-based, non-toxic paint. It's suitable for framing (or at least a spot on the refrigerator door). This activity will close at 3.
Dr. Death
122 Briggs Hall
Forensic entomologist Robert Kimsey will display and discuss his work.
Entomology at UC Davis
122 Briggs Hall
Displays of insects, including bees, ants and more. Graduate students, faculty and emeriti will staff the tables.
Fly-Tying
Briggs Hall courtyard
Fly Fishers of Davis will show attendees how to tie a fly. The recipients take home the flies.
Insect-Themed T-Shirt Sales
Briggs Hall entryway
Members of the Entomology Graduate Student Association (EGSA), led by president Mia Lippey, will be selling their popular insect-themed t-shirts, including The Beetles.
Mosquito Control Booth
Entrance to Briggs (below front steps)
Sacramento-Yolo Mosquito and Vector Control District will be providing information on mosquitoes, answering questions, and offering give-a-ways.
UC Statewide Integrated Pest Management (UC IPM)
Briggs Hall Courtyard
“We plan to have many of our usual materials on display and will be giving out the live lady beetles (aka ladybugs) again,” said urban and community IPM educator Lauren Fordyce. “We purchase them from a local garden center. In addition to that, we plan to have a prize wheel that adults and kids can spin, answer a question, and win a prize if they answer correctly. We may also have temporary insect tattoos to give away.”

Remember when San Francisco 49'ers wide receiver Brandon Aiyuk credited his spectacular 51-yard catch in the 2024 NFC championship game with the Detroit Lions to a ladybug (note that entomologists correctly call it a "lady beetle") landing on his shoe before the game?
Well, those attending the 110th annual UC Davis Picnic Day activities on Saturday, April 20 at Briggs Hall--home of the UC Davis Department of Entomology and Nematology--can also net some luck.
Children are encouraged to take home a couple of the beetles at the UC Statewide Integrated Pest Management Program (UC IPM) booth in the courtyard of Briggs. (Adults can do so, too. Maybe they'll name their beetles "Brandon" and "Aiyuk.")
The ladybug is actually a beetle (Coleoptera), not a bug (Hemiptera). It's associated with good luck because it eats the aphids that try to destroy our crops. It can eat as many as 5000 aphids in its lifetime, scientists estimate.
"These beetles have become a cultural icon of sorts because of their appearance and their beneficial habits," writes UC Davis distinguished professor Lynn Kimsey, former director of the Bohart Museum of Entomology, in her insect fact sheet on lady beetles. "Both adults and larvae feed on aphids and other small, soft-bodied insects...They are ferocious predators on small insects." (See what the UC Statewide Integrated Pest Management Program says about lady beetles.)
Ever seen a close-up shot of a lady beetle eating an aphid? The predator and the prey...
Ever seen a cellar spider snaring and eating a lady beetle? The predator and the predator...one becomes prey.
Ordinarily, the lady beetle's bright red coloration serves as a "warning" to predators. Plus, lady beetles are known to ooze a foul-tasting chemical that tastes so bad that predators leave them alone. This lady beetle engaged in "reflex bleeding," exuding an alkaloid toxin (which did not deter the predator).
Lady beetles will be just a few of the bugs at Briggs Hall during UC Davis Picnic Day. You'll also see cockroach races, maggot art, and displays featuring ants, bees, walking sticks, mosquitoes, nematodes, butterflies, spiders, whip scorpions, and more. Check out "bug" activities at Briggs Hall here. UC Davis Picnic Day is free and family friendly.

"I took a gap decade. During that time I had a series of eclectic jobs and life experiences. Those experiences proved extremely useful during my PhD."
Lamas, a former commercial beekeeper in New Hampshire, will share his life and research experiences at a seminar hosted by the UC Davis Department of Entomology and Nematology, on Monday, April 15.
His seminar, titled "How Doing a PhD Is Like Building a House," begins at 4:10 p.m. in Room 122 of Briggs Hall. It also will be on Zoom. The Zoom link:
https://ucdavis.zoom.us/j/9 5882849672
"This presentation describes how the intersection of life experiences and my PhD led to creative and generative research that led to large discovery in disease transmission dynamics in collapsing honey bee colonies," Lamas says.
A first-generation college student, Lamas received his bachelor's degree in biology in 2008 from Colby-Sawyer College, a private college in New London, New Hampshire. He obtained his doctorate in entomology at the University of Maryland in 2022.
He credits his mentor, USDA-ARS research entomologist Jay Evans of the Bee Research Laboratory, Beltsville, MD., with encouraging him to apply to become an Oak Ridge Institute for Science and Education (ORISE) fellow with the USDA-ARS Research Participation Program.
Lamas, known as "Dr. Zac," has presented programs on his research and beekeeping management to state beekeeping associations in California, Texas, Florida, Colorado, Virginia, Missouri, West Virginia, and Washington State, among others, and has addressed the American Beekeeping Federation, American Honey Producers' Association and Apimondia. Globally, he has delivered presentations to Apimondia, Montreal, Canada, and to the Eurbee 8th Congress of Apidology, Ghent, Belgium.
Lamas rears open-mated carniolans. "These are docile, productive bees, that I produce for my own experiments," he writes on his website. "We can literally pet our bees during experiments. This level of docility allows us to work intimately with the bees, sitting in front of open colonies for long periods to collect samples."
Lamas is a noted researcher on varroa mites. "Who do Varroa really feed on? Check out this presentation where I share a new finding of Varroa destructor I carried out three years of research, and along with collaborators (including my family!) individually inspected over 30,000 bees to describe the distribution of Varroa inside a colony." (See YouTube presentation.)
Lamas' recent publications involve varroa mites, infectious diseases and pesticides:

As mentioned earlier, two members of the Academic Senate's winners' circle are UC Davis Distinguished Professor Walter Leal of the Department of Molecular and Cellular Biology (and former professor and chair of the UC Davis Department of Entomology), and Professor Louie Yang of the Department of Entomology and Nematology (ENT).
Leal won the Distinguished Faculty Research Award (see Feb. 22 Bug Squad blog) and Yang won a Distinguished Teaching Award, undergraduate category (see Feb. 26 Bug Squad blog). UC Davis Distinguished Professor Bruce Hammock of ENT nominated Leal, while Joanna Chiu, professor and chair of ENT, nominated Yang.
The awards reception is Monday, May 13; more information is pending. "In all, 15 faculty members have received awards from the two groups at UC Davis," UC Davis Dateline reports. (See list of the recipients.)
Leal is the first UC Davis faculty member to win all three of the Academic Senate's most coveted awards: in research, teaching, and public service. In 2020, the Academic Senate awarded him the Distinguished Teaching Award for Undergraduate Teaching, and in 2022 Distinguished Scholarly Public Service Award.
“Dr. Leal is an internationally recognized entomologist and a world leader in his field for his groundbreaking and transformative research in insect olfaction and chemical ecology,” Hammock wrote. "Walter is truly a renaissance man. "He chaired our entomology department from 2006 to 2008, and under his tenure, our department was ranked No. 1 in the country. I've long admired (1) his rigorous fundamental research programs supported by National Science Foundation, National Institutes of Health, and the U.S. Department of Food and Agriculture, and other agencies, (2) how he tackles and solves multiple challenging problems in insect olfaction and chemical ecology, (3) his grasp of how to organize and moderate highly successful worldwide research webinars (4) his generosity in helping other succeed and (4) his finely honed sense of humor."
Wrote Chiu: "I have watched him (Professor Yang) engage, inspire, and challenge his students, fostering creative and critical thinking like no one else I've ever seen. We deeply appreciate and admire his innovative and inclusive teaching, his exemplary work ethic, his welcoming demeanor, his dedication to his students, and his nationally recognized ecology expertise. Louie has received many well-deserved teaching and mentoring awards for his teaching contributions on and off campus.”
Of special note, too, is the James H. Meyer Distinguished Achievement Award, given annually to a member of the Academic Federation for "a distinguished record in research, teaching, and/or public service." This year the award went to Kirsten Gilardi, director of Karen C. Drayer Wildlife Health Center, and a health sciences clinical professor of Medicine and Epidemiology, School of Veterinary Medicine.
Wrote Dateline: "Health Sciences Clinical Professor Kirsten Gilardi has been part of the UC Davis Community since 1989. She is currently the director of the Karen C. Drayer Wildlife Health Center, a research, service and teaching center of excellence. In 2005, she founded the California Lost Fishing Gear Recovery Program, which hires experienced commercial scuba divers to remove gear and other marine debris from near-shore waters in a safe and environmentally sensitive manner. This program continues to help reduce the potential impact of losing fishing gear and marine debris on living marine resources and underwater habitat. Beyond her significant accomplishments in her field, her colleagues around the world highlight her passion for her position at UC Davis 'that expects her to protect wild animals and wild places.'"
