When the UC Davis Department of Entomology and Nematology hosts its "bug activities" at Briggs Hall during the 110th annual UC Davis Picnic Day on Saturday, April 20, one of the most popular is maggot art.
Children and adults alike create maggot art by using plastic forceps to dip a live maggot into water-based, non-toxic paint. They then watch it--or guide it--to make the drawing they're seeking.
The result: It's suitable for framing (or at least a spot on the refrigerator door).
Rebecca O'Flaherty, a former graduate student of UC Davis forensic entomologist Robert "Bob" Kimsey, coined the educational teaching curriculum, "Maggot Art," back in 2001 when she was studying at the University of Hawaii and rearing blowflies for her forensic research.
Then, asked to create an activity to draw the interest of elementary school students, she came up with "Maggot Art." She also wanted a way to generate interest and respect for forensic entomology,
It quickly drew national interest. The CSI television show featured one of her works, “Ancient Offering,” which hung on the permanent set in Gil Grissom's office. O'Flaherty also exhibited her work at art shows, including a two-month exhibition at the Capital Athletic Club, Sacramento, in 2007.
Today, maggot art activities occur sporadically throughout the country. The Entomological Society of America acknowledged O'Flaherty here. "The basic premise is dipping prepuparial blow fly larvae (Diptera: Calliphoridae) into non-toxic ink and then placing them on a piece of paper or file card and letting them crawl around to create an abstract picture. Different larvae are used in different colours to create the picture. Rebecca O'Flaherty first demonstrated this at a North American Forensic Entomology Association Meeting many years ago, and it is a popular activity and many youtubes can be viewed to see how it works."
Sometimes the young artists get quite attached to a maggot and ask an event coordinator or parent if they can take it home. (Nobody ever gets a "yes!")

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.

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.

Doctoral student Grace Horne of the UC Davis Department of Entomology and Nematology is coordinating a City Nature Challenge Bioblitz on Saturday, April 27 from 8 to 10 p.m. in the UC Davis Arboretum and Public Garden. The family-friendly event, funded by the UC Davis Center for Citizen and Community Science, is open to all interested persons. "All ages are welcome," Horne said.
The nature challengers will meet at the Wyatt Deck, located at the west end of the Redwood Grove, across Arboretum Drive from the Wyatt Pavilion Theater. Registration is underway on this Eventbrite link:
https://iluvbugs2024.eventbrite.com.
"It's perfect for nature enthusiasts of all ages and experience levels,” Horne said, adding that it promises to be “an exciting opportunity to connect with nature and appreciate the beauty of bugs.”
Dubbed the #iluvbugs City Nature Challenge Arboretum BioBlitz and billed as "illuminating biodiversity search," the event will be an extension of Horne's first-ever "glowing bugs" exhibit (showcasing plant-insect interactions under ultraviolet light) at Briggs Hall during the 110th annual campuswide UC Davis Picnic Day on Saturday, April 20.
Bioblitz participants "will take photos of plants and animals--especially bugs!--and upload these observations to the community science platform, iNaturalist,” she said. “All you need to bring is a smartphone or a photo-taking device. We will have a table with small lenses, bug boxes, field guides, insect specimens, and more to help you make observations of wildlife. Local experts will also be available to assist in identifying the wildlife.”
The bioblitz is affiliated with the City Nature Challenge Sacramento. CNC is an annual worldwide competition among some 500 cities with the goal of documenting the most biodiversity within a four-day period. "Participants use the iNaturalist app and platform to photograph, catalog, identify, and organize observations of wildlife in their area," according to the CNC website. "From April 26-29, any iNaturalist photo uploaded within the Sacramento Region will count towards our goal of 10,000 observations."
"We are looking to make as many quality observations as we can during the UC Davis Bioblitz," said Horne, who is marking her second consecutive year hosting a bioblitz in the Arboretum.
Participants are asked to bring a flashlight, comfortable walking shoes, insect repellent, a camera/cell phone, binoculars (if desired), a water bottle, and weather-appropriate clothing.
Meineke Lab. Horne, who joined the UC Davis entomology graduate program in 2021 and studies with urban landscape entomologist and assistant professor Emily Meineke, is a 2021 graduate of Colby College, Waterville, ME, where she received her bachelor's degree in biology and environmental science, magna cum laude. Her thesis: "Reduced Performance of Ash-Specialist Caterpillars on Non-Native, Cultivated Oleaceous Plants.”
At UC Davis, Horne studies "plant-insect interactions using long-term data—primarily expert-collected observations and natural history collections. "Currently, I am investigating how moth populations in Davis and Stebbins Cold Canyon have changed over the past 30 or so years using data collected by John de Benedictis of the Bohart Museum of Entomology."
She is an alumna of The Caterpillar Lab in Marlborough, NH. "At The Caterpillar Lab, we brought together caterpillars and their host plants to teach about species interactions, conservation, and ecology," Horne said. "Our work brought us to museums, libraries, 4th grade classrooms, farmers' markets, etc."
Horne co-chairs the UC Davis Department of Entomology and Nematology's Picnic Day Committee with forensic entomologist Robert Kimsey. This year all of the department's exhibits and activities, including those hosted by the Bohart Museum of Entomology, will be at Briggs Hall.
Her Picnic Day exhibit, “I IUV Bugs," is her brainchild. The project is 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."

Scientists estimate that only 10 percent of the eggs and 'cats survive to adulthood.
They don't "survive" at all in California classrooms.
California classrooms used to showcase the metamorphosis of the monarch--from egg to caterpillar to chrysalis to adult-- but no more. If you live in California, you're not allowed to collect or rear monarchs without a scientific permit. And scientific permits are difficult to obtain.
According to the California Department of Fish and Wildlife: "A Scientific Collecting Permit (SCP) is required to handle wild monarchs in California including for educational purposes. It is unlawful to collect, remove from the wild and/or captively rear monarchs in California without an SCP, per California Code of Regulations (CCR), Title 14, section 650.
Admire them in the wild, but legally, you can't collect or rear them.
As a child growing up in the San Jose area, entomologist Jeff Smith, curator of the Lepidoptera collection at the Bohart Museum of Entomology, UC Davis, "raised and released many, many dozens of monarchs, as most empty lots were filled with vast stands of narrow-leaf milkweed, and we could easily gather caterpillars and keep them fed and healthy until they matured. This was an extraordinary thing to be able to watch--the final instar of the larva molting to change to the beautiful chrysalis and then seeing the butterfly develop within the chrysalis and hatch. We would hold it on our finger as the wings expanded and, finally, the butterfly flew away."
The Bohart Museum has some seven drawers of monarch specimens. "With around 60 specimens per drawer that could amount to nearly 400 plus specimens (some drawers are not full," he said. The collection also includes nearly-white monarch specimens from Hawaii.
In their book, The Lives of Butterflies: A Natural History of Our Planet's Butterfly Life (Princeton University Press, 2024), authors David James and David Lohman point out that "...our children are the future and it is they who will determine the future of butterflies. If a child finds a caterpillar, let them keep it, feed it, and watch it metamorphose.They will remember the experience for the rest of their life, and it will instill in them a love and appreciation for lives smaller than their own."
James is an entomologist and associate professor at Washington State University who researches migratory monarchs, and Lohman is a biologist, professor and department chair, City College of New York.
“It is important that we do not try to excessively regulate to conserve butterfly populations," they wrote. "We need people to be part of the process and be the power on the ground behind conservation programs.”
They quote Lincoln Brower (1931-2018), a renowned Lepidopterist educated at Princeton and Yale universities: “Butterflies are treasures, like great works of art. Should we not value them as much as the beauty of Picasso's art or the music of Mozart or the Beatles?"
Robert Michael Pyle, founder of the Xerces Society for Invertebrate Conservation, and colleague David L. Wagner, advocated "Keep Nets in the Hands of Kids--and Others" in a piece in the fall edition of the Lepidopterists' Society newsletter. They asked:
"Is the coup de grace for children's face-to-face fascination with small-scale life to be delivered now by well-intentioned but ill-considered regulation?"
Smith declared that the regulation will not "help" with the conservation of monarchs, and that he hopes it will be reversed or modified.
