Show me the honey? Show me the California Honey Festival.
The annual event, which emphasizes the importance of bees, and promotes honey and honey bees and their products, will take place from 10 a.m. to 7 p.m., Saturday, May 4 in downtown Woodland.
It's free and family friendly. It traditionally draws a crowd of some 40,000.
Amina Harris, who retired last June as director of the UC Davis Honey and Pollination Center, co-founded the honey festival in 2017 with the City of Woodland. She actually "retired" to the family business, Z Food Specialty and The HIVE, Woodland, where her title is "Queen bee."
The California Honey Festival continues to partner with the Honey and Pollination Center in presenting the festival.
The organizers promise "something for everyone." You can expect honey tastings, bee observation hives, kids' activities, cooking demonstrations, live music, vendors and much more. The UC Davis-based California Master Beekeeper Program, which uses science-base information to educate stewards and ambassadors for honey bees and beekeeping, will not be participating this year. But science-based information on bees will be provided by the California State Beekeepers Association and the Sacramento Area Beekeepers' Association.
Ask them questions! And remember you can sign up for classes with the California Master Beekeeper Program (CAMPB), founded (2016) and directed by Elina Lastro Niño, associate professor of UC Cooperative Extension, apiculture. She is a member of the faculty of the Department of Entomology and Nematology. As the CAMPB website indicates: The organization is "a continuous train-the-trainer effort. The CAMBP's vision is to certify Honey Bee Ambassador, Apprentice, Journey, and Master level beekeepers so they can effectively communicate the importance of honey bees and other pollinators within their communities, serve as mentors for other beekeepers, and become the informational conduit between the beekeeping communities throughout the state and UCCE staff. Explore the Certifications Page for more information."

Give them a 21-insect net salute.
That's what occurred at a recent retirement celebration honoring the legacy of UC Davis distinguished professor emerita Lynn Kimsey, director of the Bohart Museum of Entomology for 34 years.
Kimsey, who joined the UC Davis Department of Entomology (now the Department of Entomology and Nematology) in 1989, became the director of the Bohart Museum in 1990.
Noted entomologist Richard "Doc" Bohart (1913-2007) founded the insect museum in 1946. UC Davis Chancellor James Meyer (1922-2002) dedicated the facility in 1986 as "the Bohart Museum of Entomology" at a ceremony in Briggs Hall. A highlight: Faculty, postdoctoral fellows, graduate students and others saluted him with a 21-insect net salute. They lined up, formed an archway with their nets, and Professor Bohart walked under the archway.
Kimsey, who was Bohart's last graduate student, recalled that event "as one of the funniest memories" of her career when she delivered a speech last November at the Davis College of Agricultural and Environmental Sciences (CA&ES) event honoring recipients of its excellence awards. Kimsey received the Exceptional Faculty Award.
Kimsey retired on Feb. 1, 2024 (but she's still doing research and continues to be the executive director of the Bohart Museum Society and the writer-editor-publisher of the quarterly Bohart newsletter.)
Then came the retirement celebration on April 6. Her colleagues, collaborators, faculty, staff and students gathered in a Mathematics Building classroom on Crocker Lane for speeches, and then headed over to the nearby Bohart Museum for the 21-insect net salute, a buffet and more tributes.
As Kimsey walked beneath the archway of the 21-insect net salute leading into the Bohart Museum, a chorus of cheers and applause greeted her.
She always remember that.
Just as she remembers the first insect net she received at age 5.
“I've always been interested in insects," Kimsey said. "I got my first insect net at age 5.” A portrait of her holding that net graces the Bohart Museum.
Under Kimsey's direction, the Bohart Museum that "Doc" Bohart founded 78 years ago expanded from 400 specimens to some eight million insect specimens today. It is the seventh largest insect collection in North America.
A recognized authority on biodiversity, systematics and biogeography of parasitic wasps, urban entomology, civil forensic entomology, and arthropod-related industrial hygiene, Kimsey holds two entomology degrees from UC Davis: a bachelor's degree (1976) and a doctorate (1979). "I got to pursue my bug interests," she said. "I know it was kind of weird, but even as a little kid it was fun."
It still is, Kimsey told the crowd at her retirement celebration.
The new Bohart Museum director is arachnologist and Professor Jason Bond, the Evert and Marion Schlinger Endowed Chair in the Department of Entomology and Nematology and associate dean, College of Environmental Sciences (CA&ES).

Assistant professor Laura "Melissa" Guzman of the University of Southern California (USC) will discuss "Using Occupancy Models to Infer Trends of Bee Biodiversity in North America" at the April 29th seminar hosted by the UC Davis Department of Entomology and Nematology.
Her seminar begins at 4:10 p.m. in 122 Briggs Hall and also will be on Zoom. The Zoom link:
https://ucdavis.zoom.us/j/9 5882849672
"Historical museum records provide potentially useful data for identifying drivers of temporal trends in species occupancy, however, because these records were not explicitly collected for this purpose, methodological developments are needed in order to enable robust inferences," Guzman writes in her abstract. "Occupancy-detection models, a relatively new and powerful suite of methods, are potentially useful here, because these models allow us to account for changes in collection effort through space and time. Applying such occupancy-detection models to historical museum records is not a straightforward process, as these models have strict data requirements that museum data usually do not meet."
"Here I will present a methodological road-map for using occupancy models to analyze historical museum records. I use simulated data-sets to identify how and when modeling decisions and patterns in data can bias inferences. I will focus primarily on the consequences of contrasting methodological approaches for dealing with species ranges and non-detections in both space and time. Finally, I will present an application of these methods to bees in North America and will present drivers of change for these species in the past 30 years."
Guzman says that the "overarching goal of my research is to develop statistical and computational methods to leverage large biodiversity datasets to learn about ecological processes. While we know that the distribution of some species is changing, it is actually very difficult to make reliable inferences as to which species are declining and by how much from the often messy and complex historical and spatial datasets that we have to work with — for example, historical museum records, where species occurrences are aggregated from studies with different sampling procedures."
"In order to address this gap," Guzman says, "my research focuses on determining if and how statistical models can be applied to historical records without yielding biased trends. In my research I also apply these statistical models to determine how the distribution of pollinators has changed through time, where museum records provide lots of information. I am also interested in determining which drivers (e.g. pesticide use, climate change, land use change, etc.) are causing the most decline of the most pollinator species."
"Another aspect of my research is to understand the processes that shape communities, for example, I have combined experiments and modelling to understand how the structure of body size in a community affects the stability of food webs. In more recent work, I used large-scale simulations and machine learning to identify the signal of metacommunity processes in ecological time series."
Guzman is a Gabilan assistant professor in USC's Department of Biological Sciences. She received two degrees from McGlll University: her bachelor's degree (2012) in biology and her master's degree (2013) in ecology and evolution. She obtained her Ph.D. at the University of British Columbia.
She recently co-authored a piece in the journal Ecology titled "A Data Set for Pollinator Diversity and their Interactions with Plants in the Pacific Northwest," published in November 2022.
The abstract:
"Pollinator populations have declined substantially in recent years. The resulting loss in pollination services has both ecological and economic consequences, including reductions in plant diversity and crop production and lower food security. Data sets that identify pollinators and their plant hosts are of the utmost importance for the light can shed on the main causes of pollinator declines. Here we present a data set that contains 67,954 individual pollinator records. The data were collected across the Pacific Northwest, primarily focused in British Columbia (Canada), with 182 individual sites over 11 years, between 2005 and 2017. This data set comprises multiple studies that aimed to collect information on pollinator abundance, diversity, and their interactions with plants. Overall, the data set includes 937 morphospecies (of which 482 were identified to the species level) of pollinators across 105 families, including data for bees, wasps, butterflies, moths, and flies. We also present information on the interactions of these species, with 473 species of plants. The data set is being released for noncommercial use only. Credits should be given to this paper (i.e., proper citation)."
Guzman won the American Society of Naturalists Young Investigator Award, 2022-2023, and the Canadian Society of Ecology and Evolution Early Career Award, 2022-2023.

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.

Well, it wouldn't be a picnic at all!
The UC Davis Department of Entomology and Nematology (ENT) is planning scores of displays and activities at Briggs Hall for the 110th annual campuswide UC Davis Picnic Day, to take place Saturday, April 20.
Think ants, bees, beetles, butterflies, flies, cockroaches, maggots, mosquitoes, nematodes, spiders and scorpions.
And more.
This year, all of the entomology exhibits, including those at the Bohart Museum of Entomology, will be at Briggs Hall. (The Bohart Museum headquarters in the Academic Surge Building will be closed on Picnic Day.)
Hours? From 9 a.m. to 5 p.m. The Bohart Museum's pop-up tent in front of Briggs, featuring insect specimens and an insect petting zoo, will be open from noon to 4 p.m.
The entomology displays traditionally draw some 3000 attendees, said the ENT co-chairs, doctoral student Grace Horne of the Emily Meineke lab, and faculty member and forensic entomologist Robert "Bob" Kimsey. It's all free and family friendly.
Among the crowd pleasers are the cockroach races, maggot art, stick insects, and the Bug Doctor booth. The doctor is always in!
New to the line-up is the “I IUV Bugs," an exhibit about plant-insect interactions under ultraviolet light. The "glowing bugs exhibit" is the brainchild of Horne and primarily designed by the Meineke lab, "especially (doctoral student) Marielle Hansel Friedman," Horne said. "We will have plants from the UC Davis Arboretum Teaching Nursery and local/pet-trade arthropods which glow under ultraviolet light. With this exhibit, we seek to highlight the interplay between light, color, and species interactions."
Doctoral student Veronica Casey of the Shahid Siddique lab designed the new nematode exhibit. Carla-Cristina "CC" Melo Edwards of the Geoffrey Attardo lab is coordinating the new medical entomology display. "The bumble bee observation hive is unfortunately not ready for the spotlight this year," Horne said.
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 event will close at 3 p.m. this year (last year it was at 5 p.m.)
Dr. Death
122 Briggs Hall
Forensic entomologist Robert Kimsey will display and discuss his work in his "Dr. Death" booth. Last year Kimsey pin-mounted and identified flies from various cases and research efforts, and displayed studies on the sequence of development of individual maggots, calling attention to the development and sequence of communities of insect maggots. "By these means, approximations about how long a person has been dead can be made," he told the crowd.
Entomology at UC Davis
122 Briggs Hall
Displays of insects, including bees, ants and more. Graduate students, faculty and emeriti will staff the tables.
Bohart Museum of Entomology
Front of Briggs Hall
A pop-up tent, staffed by the Bohart Museum, will include stick insects (walking sticks) and Madagascar hissing cockroaches. "We are excited to be part of the bigger department's offerings," said Tabatha Yang, education and outreach coordinator. Give-aways are also planned.
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. The T-shirt, EGSA's all-time best seller, is a take-off of the cover of The Beetles' Abbey Road alum. However, instead of the Beatles crossing the road in a single file, four beetles (family names Phengogidae, Curculionidae, Cerambycidae and Scarabaeidae) do so.
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 handing out give-a-ways, including mosquito repellent.
