What's a picnic without bugs!
The UC Davis Department of Entomology and Nematology is gearing up for the 110th annual UC Davis Picnic Day, set April 20.
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.)
Picnic Day at Briggs Hall is from 9 a.m. to 5 p.m. Some of the activities will closer earlier.
The list of events and activities in and around 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 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.
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.”
Ranked Third in the Country. The UC Davis Department of Entomology and Nematology is ranked third among “The Best Entomology Colleges in the United States for 2024" by universities.com. The department includes 24 active and 19 retired faculty; 28 graduate students (five in the master's degree program and 23 in the doctoral degree program); 47 undergraduate entomology majors (based on the Office of Academic Support and Instructional Services (OASIS) Student Reports); and a staff comprised of 27 academics (non-faculty), 24 career, and 56 student assistants.

There's no fame, fortune or glory in writing a daily (volunteer) Bug Squad blog.
It's about the insects. It's always been about the insects, from honey bees to bumble bees, to butterflies, to dragonflies, to praying mantises and more.
Why? Just call it a fascination for insects, which evolved some 400 million years ago. "Three-quarters of all known animals are insects, a staggering 1 million species in total with an estimated 4 to 5 million yet to be discovered," according to a November 2015 article in New Scientist. "By contrast, there are fewer than 70,000 vertebrate species. Harvard University entomologist Edward O. Wilson has suggested there may be as many as 10 quintillion insects alive at any one time – that's 1018, or more than a billion for each person on the planet. They have colonised every continent, including Antarctica. They can live in air, land and water. They even live on us – lice evolved as soon as there was hair and feathers to set up home in. They are the kings of the arthropods – animals…"
I began writing the Bug Squad blog (at the invitation of Pam Kan-Rice) on the UC Agriculture and Natural Resources (UC ANR) website on Aug. 6, 2008, and have written it every night, Monday through Friday, never missing a single night of posting. Today that amounts to 4020. Along the way it's been named the No. 4 "bug blog in the world" (there aren't that many of us!) And, it has won some international awards. My photos have landed on the covers of several scientific journals and popular magazines, and in a few scientific books and children's books (all donations).
My photography has also resulted in thousands of copyright infringements. One man in Austria falsely claimed one of my images and was selling it on four stock photo platforms, including Getty Images. Others deliberately erase the copyrights and steal the images for their commercial purposes.
It's fun until it isn't.
Where do I take the images? Almost all are from our family's pollinator garden. My gear includes a Nikon Z7 mirrorless camera, a Nikon D800, a Nikon D500, a Canon AE1, coupled with half-a-dozen macro lenses. It's exhilarating to capture an image of a honey bee in flight, a monarch butterfly laying an egg, a dragonfly catching prey, or even to go eye-to-eye with a Western yellowjacket.
I don't poke 'em, prod 'em, or pin 'em. I am a guest in their habitat.
So, in 2023, "These are a few of my favorite things" (thanks, Oscar Hammerstein II and Richard Rodgers):

Members of the Entomology Graduate Student Association (EGSA) of the UC Davis Department of Entomology and Nematology design insect and arachnid-themed T-shirts that are all the fashion.
The critters climb, crawl, jump, roll, flutter, buzz, fly or otherwise position themselves on EGSA T-shirts.
If you've ever seen the EGSA booth at Briggs Hall during the campuswide annual UC Davis Picnic Day, you know how popular the T-shirts are.
They are hot-ticket items during the holiday season, too. They can be viewed and ordered online at https://mkt.com/UCDavisEntGrad/.
EGSA president Mia Lippey, a doctoral student in the laboratories of UC Davis distinguished professor Jay Rosenheim and assistant professor Emily Meineke, says that currently, the designs offered are:
- The Beetles (in black or red)
- Entomo Gothic (a play on the American Gothic, in grey)
- Whip Scorpion (in lavender and black)
- Bee-Haw (in black)
- They See Me Rollin' (dung beetles rolling a poop, in heather blue)
- Et in Terra (dark green)
- Entomophagy (in blue and green)
All T-shirts come in sizes from XS to XXL.
"The Beetles" T-shirt is EGSA's all-time best seller. Instead of the English rock band John Lennon, Paul McCartney, George Harrison and Ringo Star crossing Abbey Road in single file (that's the iconic image on the cover of their album, Abbey Road), think of The Beetles (four insects) crossing Abbey Road in single file. Beneath the images of the beetles are their family names: Phengogidae, Curculionidae, Cerambycidae and Scarabaeidae. Think glowworm, snout, long-horned, and scarab beetles.
One of the newer designs is "Bee Haw," of a honey bee disguised as a cowgirl, complete with hat and rope. The entomophagy ("eating insects") T-shirts are also "in," as are those that whip and roll--whip scorpions and dung beetles.
They are also great conversation pieces! What's that design on your shirt? Where did you get it?

The event: The 13th annual UC Davis Biodiversity Museum Day, a Super Science Day.
It's an opportunity to see scientists in action.
It's day when you can visit such biological museums or collections as the Phaff Yeast Culture Collection, Bohart Museum of Entomology, Museum of Wildlife and Fish Biology, Arboretum and Public Garden, California Raptor Center, Earth and Planetary Sciences Paleontology Collections, Botanical Conservatory, Center for Plant Diversity, Nematode Collections, Marine Invertebrate Teaching Collection, and the Department of Anthropology Museum.
And it's free and open to the public.
The date has not been set, but the first few Biodiversity Museum Days took place on Presidents' Day weekend. The committee will announce the date soon.
"Each year more than 200 volunteers--students, staff and faculty--from across campus help more 4,000 visitors--including other UC Davis students, staff and faculty--learn about biodiversity through our amazing biological collections," said UC Davis Biodiversity Museum Day chair Tabatha Yang, education and outreach coordinator for the Bohart Museum of Entomology.
Donations, from $5 on up, may be made at this website: UC Davis October Crowdfund campaign. It costs approximately $5000 to finance the Biodiversity Museum Day, the committee related. Donors may make contributions to honor a loved one or a favorite organism, such as a praying mantis, plant, nematode or fossil. The crowdfunding campaign ends at 11:59 p.m., Tuesday, Oct. 31.
The committee asks that you:
- Share the news with three friends/co-workers/neighbors
- Post on your social media. The UC Davis Crowdfund has links for Facebook, LinkedIn and Twitter (or X)
- Donate here
Coordinating the UC Davis October Crowdfund campaign are Yang; Brennen Dyer, collections manager for the Bohart Museum; and Melissa Cruz Hernandez, outreach and leadership program manager for the UC Davis Arboretum and Public Garden.

He told the villagers to line up in town square with their sickles. When they did, he immediately fingered the killer. The killer confessed.
How did Song Ci know? Because minute traces of blood left on the "cleaned" sickle drew a swarm of blow flies.
That was one of the stories that UC Davis forensic entomologist Robert "Bob" Kimsey of the Department of Entomology and Nematology recounted in his 45-minute talk during the Bohart Museum of Entomology open house on "Forensics and Insects."
Song Ci, also a judge, physician, anthropologist and writer, went on to author the book, Collected Cases of Injustice Rectified, containing the oldest known cases of forensic entomology.
In his presentation, Kimsey discussed the life cycle and development of blow flies and other insects. He is frequently called as a expert court witness at murder trials.
"Correct species identification is all important," said Kimsey, aka "Dr. Bob," in noting that different species have different development rates. He compared the life cycle of four species--Cochliomyia macellaria (secondary screwworm), Chrysoma rufifacies (a blow fly species), Phomia regina (a black blow fly), and Lucilia sericata (a common green bottle fly)--developing at a temperature of 27 Celsius. C. macellaria is the fastest and P. regina is the slowest, he said.
Kimsey also showed a chart illustrating the approximate age of a blow fly developing during a temperature of 72 degrees Fahrenheit. Another chart included information on the succession of arthropod taxa on carrion.
Following his talk, held in the nearby Museum of Wildlife and Fish Biology lecture room, Kimsey fielded questions in his "Dr. Death booth" in the Bohart Museum. He annually portrays Dr. Death at Briggs Hall during the annual campuswide UC Davis Picnic Day every April.
At the open house, the Bohart Museum displayed a number of species involved in forensic entomology, including
- Acalyptrate flies, numerous and diverse families, scavenging maggots
- Bluebottle flies, family Calliphoridae, scavenging maggots
- Green bottle flies, family Calliphoridae, scavenging maggots
- Large carrion, or burying beetles, family Silphidae
- Flesh flies, family Sarchophagidae, scavenging maggots
- Coffin flies, family Phoridae, scavenging maggots
- Clown or hister beetles, family Histeridae, predaceous beetles
- Red-legged ham beetle, family Cleridae, omnivorous predators that also scavenge
- Sap beetles, family Nitidulidae, "indirect" scavenge beetles
- Cockroaches, order Blattodea, scavenging larvae and adults
- Rove beetles, family Staphylinidae, predaceous beetles and their larvae
- Termites, infraorder Isoptera, scavengers for nitrogen
- Ants, family Formicidae, predators and scavengers
Ants: "Ants are a nightmare for the forensic entomologist! They are of little use as evidence as yet, but they can easily confound the development of vital evidence by establishing residency and defending the decedent from other scavengers, and further delay development of vital evidence by carrying off fly eggs and small maggots. Thus, they can delay progress of insect-mediated decomposition and feed vital evidence to their developing larval ants: the first, thus oldest and most important maggot cohorts (to the forensic entomologist)! They also ambush, kill and dismember female flies coming to the decedent to lay eggs."
Green Bottle Flies: "Green bottle flies are iridescent green in color. They belong to the genus Lucilia and comprise some of the most common flies with maggots that feed on carrion. A number of species, including the green bottle fly, Lucilia sericata, and the bronze bottle fly, Lucilia cuprina, have been introduced worldwide by human commerce, and the later, also known as the Australian sheep blow fly, commonly infests living sheep in Australia, causing enormous economic damage."
Termites: "In other parts of the world, insects exotic to what we in the temperate zones consider to be the standard groups associated with carrion, assist in the decomposition process. Termites in Central America exemplify such 'exotics' to decomposition, building mud casings over and defending carrion against all comers in an effort to garner nitrogenous materials to supplement their extremely nitrogen-poor diet."
Clown or Hister Beetles: "Distinctively shiny black and resembling a pill, these small to very small beetles feed on a great diversity of small arthropods found in carrion, including the smallest stages of maggots, fly eggs and scavenger or predaceous mites. Active at night, the numerous carrion-associated species appear in nearly all stages of decomposition, often specializing on prey found only in a particular stage.
Flesh Flies: "This very large family consists of large robust scavenger species and small species that parasitize other insects. The scavengers, Sarchophaga and Blaesozipha, frequently do not usually lay eggs but frequently deposit a small number of first-stage maggots on carrion, which puts their maggots at a distinct advantage over maggots of egg-laying species."
Cockroaches: "A number of cockroach species found around the house (peridomestic) will gnaw on the skin of decedents indoors during the early fresh stage of decomposition. They are well known to chew on the calluses, clean debris from under the fingernails and around the toes of sleeping sailors on ancient sailing ships right through to the current day. This kind of depredation occurs in circumstances of overwhelming cockroach infestations. In similar circumstances, they are also responsible for chewing on the ears and eyelashes of newborn infants in cases of child neglect."
The family art-and-crafts activity involved maggot-inspired art. Participants dipped maggots in non-toxic, water-based paint and guided them on white paper to create their masterpieces, suitable for framing or at least as conversation pieces. (Photos to appear in June 9th Bug Squad blog)
The next open house at the Bohart Museum is "Night at the Museum" (Moth Night) from 7 to 11 p.m. on Saturday, July 22. All open houses are free and family friendly, and parking, too, is free.
The Bohart Museum, directed by UC Davis distinguished professor Lynn Kimsey, houses a global collection of eight million insect specimens. It also maintains a live "petting zoo" (Madagascar hissing cockroaches, walking sticks, tarantulas and more) and an insect-themed gift shop, stocked with t-shirts, hoodies, jewelry, posters, books, pens and collecting equipment.
The Bohart Museum is located in Room 1124 of the Academic Surge Building, 455 Crocker Lane, UC Davis campus. The Bohart will be open to the public (walk-ins) only on Tuesdays from 2 to 5 p.m., this summer, starting June 13. This is due to the high number of outreach programs, summer camps, scheduled tours and unavailability of staff. More information is available on the website or by emailing bmuseum@ucdavis.edu.
