Maggot Art. Yes, you read that right. Maggot Art.
It's a traditional and popular part of the Department of Entomology and Nematology's many activities at Picnic Day. This year the UC Davis Picnic Day is Saturday, April 12, and the Briggs Hall events take place from 10 a.m. to 3 p.m.
Maggot Art is especially for children, but anyone can participate. You grab a special pair of forceps, pick up a maggot, dip it into non-toxic, water-based paint and let it crawl around on white paper. Voila! Maggot Art. Suitable for framing!
Rebecca O'Flaherty, former entomology doctoral candidate at UC Davis, coined and trademarked the term in 2001 while a student at the University of Hawaii. She was organizing a community outreach program and seeking ways to teach youngsters about insects. Not to hate them. Not to fear them. To respect them and learn about them.
Maggot Art was the way. Her way. It worked.
"I love my work and being able to share my love with so many people has truly been a joy," she told us in an interview back in 2007. "I tend to target young elementary students, second and third graders, because I find that at that age, most children are enthusiastic, uninhibited and extremely open to new ideas. They haven't developed aversions to insects, and we're able to instill in them an appreciation for and interest in all organisms, no matter how disgusting those organisms may be perceived to be."
Some adults find maggots revolting, she acknowledged. "A few parents have pulled their children away with a 'Eeew!' and 'Don't touch that!'"
Since 2001, O'Flaherty has taught thousands of students, ranging from kindergarteners to college students to law enforcement professionals. She even showcased her own Maggot Art at a 2007 art show in the Capital Athletic Club, Sacramento. Some art critics compared her work to that of American abstract expressionist Jackson Pollock.
While at UC Davis, O'Flaherty studied with major professor/forensic entomologist Robert Kimsey. Although she no longer participates in Picnic Day's Maggot Art, her art continues.
UC Davis entomology undergraduate and graduate students now guide little hands in creating art that is like no other.
Some youngsters are concerned about the welfare of the maggots (no maggots are harmed in the making of the paintings) and a few ask to take the maggots home.
Just the art work goes home, thank you. No maggots, please.

Frankly, who would want to attend a picnic WITHOUT bugs?
The UC Davis Department of Entomology and Nematology is gearing up for the 100th annual campuswide UC Davis Picnic Day, set from 10 a.m. to 3 p.m., Saturday, April 12.
Come one, come all.
Bugs, too. Bugs at Briggs. Bugs at Bohart.
That would be Briggs Hall and the Bohart Museum of Entomology.
Lots of fun and educational activities revolving around insects will be offered, according to forensic entomologist Robert Kimsey, coordinator of the activities at Briggs Hall, and Lynn Kimsey, director of the Bohart Museum.
The Bohart Museum, located in Room 1124 of the Academic Surge Building on Crocker Lane, is home to nearly 8 million insect specimens. It also features a live “petting zoo” where visitors can hold Madagascar hissing cockroaches, a rose-haired tarantula and walking sticks. The focus on Picnic Day will be "recently discovered and insects that are threatened and extinct," said Tabatha Yang, education and outreach coordinator at the Bohart Museum.
At Briggs Hall, located off Kleiber Hall Drive, the popular events will include maggot art (suitable for framing--at least for posting on your refrigerator), termite trails, cockroach races and honey tasting, as well as displays featuring forensic, medical, aquatic, apiculture and forest entomology. Exhibits also will include such topics as fly fishing/fly-tying, insect pests of ornamentals, and pollinators of California. In addition, you'll see bug sampling equipment.
Extension apiculturist Eric Mussen, coordinator of the honey tasting, will share six varieties of honey: Almond, yellow starthistle, leatherwood, cultivated buckwheat, safflower and “wild oak.” Each person will be given six toothpicks to sample the varieties.
The UC Statewide Integrated Pest Management Program (UC IPM) will provide a display in front of Briggs Hall. Visitors can learn about managing pests in their homes and garden. In addition, live lady beetles (aka ladybugs) will be distributed to children.
Plans also call for a “Bug Doctor” to answer insect-related questions from the public. That's called "bugging the Bug Doctor."

A honey bee apparently stung a 47-year-old father on his foot and he went into anaphylactic shock. Rushed to the hospital, he died 10 days later when his kidneys and heart failed. The article reported he was 6 feet, five inches tall, and weighed 17 stones, which is 238 pounds. (One stone equals 14 pounds).
His family indicated he was unaware of his allergic reaction to bee stings.
A sad and tragic case, indeed.
We know of people who have suffered severe allergic reactions and were raced to the hospital in time and fortunately survived. One was a Northern California parks employee who did not know he was allergic to bee stings.
How many people in the United States are allergic to honey bee stings? Approximately one or two out of every 1000 people, says Extension Apiculturist Eric Mussen of the UC Davis Department of Entomology and Nematology. "The severity of the response, to even a single sting, varies considerably from person to person."
Immediate injections with epinephrine will usually delay the possibility someone unable to breathe. Then a quick trip to a hospital where medical personnel can administrate antihistamines, steroids "and likely more epinephrine" are in order.
"While honey bees away from their hives normally do not pose too much of a sting threat, if the bees are intoxicated by exposure to certain pesticides, they can become an abnormal sting threat at distances quite a ways from the hives. Additionally, individuals who fear a sting, with good reason, sometimes are more apt to try to shoo the bee away. If a bee already is close to stinging, the additional movement of the 'shooer,' or if there is contact with the bee, results in a much greater likelihood of a sting."
Another piece of good advice that Mussen offers: "Individuals who do not appreciate attention by bees should do everything they can to not smell good to a bee. The use of flower-scented or bee products-scented soaps, shampoos, perfumes, or colognes should be avoided. There is no documented scientific study that suggests that honey bees can detect the odor of fear in humans. But if we watch from a distance, the physical reactions of fearful people often tend to be more likely to cause stings than the behavior of the rest of us."
Photographers who capture images of worker bees foraging in flowers are often asked if they've ever been stung. After all, they're just inches away from them. The usual answer: No. The bees are too busy gathering nectar and pollen for their colonies. Stings can and do occur when the worker bees are defending their hives. Or when you accidentally step on one.

What are the indirect effects of parasites and pesticides on pollination service?
Ecologist Sandra Gillespie, a postdoctoral researcher in the Neal Williams lab, UC Davis Department of Entomology and Nematology, will present the results of her research at a departmental seminar from 12:10 to 1 p.m., Wednesday, Oct. 16 in 122 Briggs Hall. It will be recorded for later posting on UCTV.
“Whether in natural or agro-ecosystems, researchers are increasingly viewing positive interactions such as pollination in a broader context rather than as isolated pair-wise interactions,” Gillespie says. “In natural ecosystems, my research has explored how incidence of parasites and diseases of native bumble bees may affect pollination of plants in old-field meadows in Massachusetts. High incidence of certain parasites reduced pollination of bumble bee-dependent wild plants, suggesting that parasitism may impact pollination service to native plants and crops.”
“In a more applied context, I examined the effects of field management decisions, including pesticide use and irrigation practices, on pollination service in onion seed production in California. High insecticide use, even pre-bloom, as well as reduced irrigation negatively impact pollinator visitation in this crop, highlighting the importance of considering the indirect effects of management on the pollination process in agro-ecosystems.”
Gillespie delivered a similar presentation at 2012 meeting of the Pacific Branch of the Entomological Society of America.
Gillespie, a postdoctoral researcher at UC Davis since 2011, received her bachelor’s degree in biology from Simon Fraser University, Canada, and her doctorate in both entomology and organismic and evolutionary biology from the University of Massachusetts, Amherst.
As a postdoc in the Williams lab, Gillespie is examining the mechanisms behind yield declines in hybrid onion seed production in California, with the goal of developing sustainable recommendations for producers.
Gillespie will be leaving UC Davis the first week of December; she has accepted a position at Simon Fraser University (starting Jan. 1) to work as a postdoc with Elizabeth Elle in the biology department. "I'll be studying pollinator-mediated selection in a community and landscape context," she said.
Her research on “Factors Affecting Parasite Prevalence among Wild Bumble Bees,” was published in Ecology Entomology, 2010. She has also published her work in the American Journal of Botany (“Variation in the Timing of Autonomous Selfing among Populations that Differ in Flower Size, Time to Reproductive Maturity, and Climate,” 2010) and Annals of the Entomological Society of America (“Laboratory Rearing of North American Tiger Beetles (Coleoptera, Carabidae: Cicindelinae,” 2011).
Pending publication in the Journal of Economic Entomology: “Insecticide Use in Hybrid Onion Seed Production Affects Pre- and Post-Pollination Processes,” the work of Gillespie, Neal Williams, Rachael Long and Nicola Seitz.

It's a topic we've all been waiting for: "Honey Bee Health and Disease Resistance."
Jay Evans, a research entomologist with the USDA's Agricultural Research Service (USDA-ARS) Beltsville Bee Research Laboratory for the past 14 years, will discuss "Bee Disease Resistance and Colony Health" on Wednesday, Oct. 2 to open the fall seminar series hosted by the UC Davis Department of Entomology and Nematology.
His lecture, open to all interested persons, is from 12:10 to 1 p.m. in Room 122 of Briggs Hall, located on Kleiber Hall Drive, UC Davis campus.
"Honey bees are vulnerable to poor nutrition, parasites and pathogens, and exposure to chemicals," Evans said. "These threats can occur in batches and little is known about the impacts of multiple challenges to honey bee health, and about the abilities of bees to fend off these threats. I will present recent work aimed at determining the impacts of multiple parasites on bee health. I will also discuss the impacts Varroa mites, chemicals, and bacterial symbionts on bee health and colony losses."
As a research entomologist, Evans has focused his projects on a range of bee pests including bacteria, fungi, viruses and, mites, and beetles. He is especially interested in the immune defenses of bees toward these threats.
Evans was an early proponent of the Honey Bee Genome Project and helped recruit and organize scientists interested in applied genomics for bees. He has improved and applied genetic screens for possible causes of colony collapse disorder and is now heading a consortium to sequence the genome of the Varroa mite in order to develop novel control methods for this key pest.
Evans holds a bachelor's degree in biology from Princeton and a doctorate in biology from the University of Utah.
The fall seminars, coordinated by faculty members Joanna Chiu and Brian Johnson, will be held every Wednesday noon through Dec. 11 in 122 Briggs Hall, except for Nov. 27, Thanksgiving Week, when no seminar will be held.
Under the coordination of professor James R. Carey, all seminars are to be videotaped and posted at a later date on UCTV.
Anyone with a computer can view the seminars, and yes, they're free.
