The UC team, which swept the national championship last year, just won the regional competition Monday night at the Pacific Branch, Entomological Society of America (PBESA) meeting in San Diego. The Linnaean Games, launched in 1983, are lively, college-bowl style competitions on entomological facts, including questions on insects and entomologists.
The UC team is comprised of UC Davis and UC Berkeley graduate students: captain Ralph Washington Jr., who received his bachelor of science degree at UC Davis and is now a graduate student at UC Berkeley; doctoral candidate Brendon Boudinot of the Phil Ward lab, UC Davis; and graduate student Zach Griebenow of the Phil Ward lab.
At the PBESA meeting, UC Riverside took second, and Washington State University, third.
The UC Team will now defend its championship at the ESA meeting , set Nov. 17-20 in St. Louis, Mo. Both the first and second-place teams from each of the ESA's six branches are eligible to compete.
Question: The Passandridae are a family of beetles. What is unusual about their larvae?
Answer: The larvae are ectoparasitoids of wood-boring insects
Both Boudinot and Washington have received major accolades at the ESA and PBESA meetings. Boudinot, who researches ants, won the 2019 John Henry Comstock Award, the highest graduate student award presented by PBESA. He delivered a presentation on his research at the San Diego meeting. He next will be honored as one of the six Comstock award winners (one from each ESA branch) at the national meeting.
Washington, who at UC Davis studied with major professors Steve Nadler, professor and chair of the UC Davis Department of Entomology and Nematology, and assistant professor Brian Johnson, won PBESA's 2017 Student Leadership Award.
PBESA encompasses 11 Western states, plus U.S. territories and parts of Canada and Mexico. ESA, the world's largest entomological society, is comprised of 7000 members.
Her research already has.
She just won the prize for best student presentation at the recent 9th International Congress of Dipterology in Windhoek, Namibia.
Gillung delivered her presentation on “Phylogenetic Relationships of Spider Flies (Acroceridae) – Discordance, Uncertainty and the Perils of Phylogenomics.” Acrocerid adults are floral visitors, and some are specialized pollinators, while the larvae are internal parasitoids of spiders.
Approximately 350 delegates attended the conference; the scientists focus on the Diptera order, which includes houseflies, mosquitoes, and gnats. Gillung was among 40 students presenting their research.
Gillung studies with major professor Lynn Kimsey, director of the Bohart Museum of Entomology and professor of entomology, UC Davis Department of Entomology and Nematology; mentor Shaun Winterton of the California Department of Food and Agriculture; and collaborator Phil Ward, UC Davis professor of entomology.
UC Davis doctoral students Charlotte Herbert Alberts and Socrates Letana, who both study with Kimsey, also presented their work; Alberts delivered an oral presentation on her research (she studies Asilidae (Assassin flies), and Letana displayed a poster on bot flies.
Presenting the award to Gillung was Professor Thomas Pape of the Natural History Museum of Denmark and chair of the Council for the International Congresses of Dipterology, which organizes the conferences. The next Congress takes place in 2022 in California.
In her abstract, Gillung described spider flies “as a monophyletic group of lower Brachycera currently classified into three subfamilies, 55 genera and ca 530 species.”
“The group has long been considered a rogue taxon and its placement within the Diptera tree of life remains uncertain,” she wrote. “Phylogenetic relationships among lineages of spider flies are by contrast relatively well established, with hypotheses proposed based on molecular data from both Sanger and high-throughput sequencing. Phylogenomic estimation of spider fly relationships yields different topologies, depending on whether data is coded and analyzed as nucleotides or as amino acids. The most significant difference among the two data types is in the monophyly of Panopinae; a morphologically and ecologically recognizable group, that is recovered as monophyletic only in the analyses of nucleotides. This study uses Acroceridae as a system to explore the effects of potential confounding factors in phylogenomic reconstruction. This research takes advantage of modern and powerful statistical approaches, including posterior predictive simulation, to understand the effects of conflict, uncertainty and systematic error in the estimation of evolutionary relationships using the standard phylogenomic toolkit.”
Fast forward to her exit seminar, which she will deliver at 2 p.m., Friday, Dec. 14 in 122 Briggs Hall, located off Kleiber Hall Drive. The title: “Evolution of Fossil and Living Spider Flies (Diptera, Acroceridae): A Tale of Conflict and Uncertainty."
"Parasitoid flies," Gillung wrote in her abstract for her Dec. 14 seminar, "are some of the most remarkable, yet poorly known groups of insects. Represented by over 10,000 species distributed in 21 families, dipteran parasitoids comprise over 100 independent lineages, offering an unparalleled system to understanding the origin, evolution and diversification of the parasitoid life history. My dissertation research unraveled the systematics, evolution and biology of a lineage of dipteran parasitoids specialized in spiders, Acroceridae, commonly known as spider flies. My research resulted in a monograph of fossil spider flies, and a robust hypothesis for the pattern and timing of spider fly evolution based on high throughput sequencing. Through the combination of DNA sequence data obtained via Sanger sequencing with morphological characters, I also estimated their relationships among spider fly genera using an extensive taxon sampling which culminated in a new taxonomic classification for the family.”
Gillung has accepted a postdoctoral position at Cornell University, Ithaca, beginning Jan. 2. She will be working with Bryan Danforth on Apoidea (stinging wasps and bees) phylogenomics, evolution and diversification.
She recently was named the recipient of the prestigious 2018 Student Leadership Award, presented by the Pacific Branch, Entomological Society of America (PBESA), which represents 11 states, seven U.S. territories, and parts of Canada and Mexico.

The incredible University of California Linnaean Games Team, comprised of graduate students from UC Davis and UC Berkeley, won the national championship at the popular and highly competitive Linnaean Games hosted this week at the Entomological Society of America's meeting in Vancouver, B.C.
This makes the third year that a UC Davis-based team has won the national championship.
"In the final, UC defeated Texas A&M (graduate students), 140-20," said Joe Rominiecki, manager of communications for the Entomological Society of America (ESA). "UC defeated the University of Florida 110-100 in the semifinal round. In the preliminary round, UC defeated the Texas A&M undergrad team."
The Linnaean Games, launched in 1983, are lively question-and-answer, college bowl-style competitions on entomological facts and played by winners of the ESA branch competitions. The teams score points by correctly answering random questions.
The UC team is comprised of captain Ralph Washington Jr., a UC Davis entomology graduate who is studying public policy at UC Berkeley; UC Davis doctoral students Brendon Boudinot, Jill Oberski and Zachary Griebenow, all of Phil Ward lab, specializing in ants; and UC Davis doctoral student Emily Bick of the Christian Nansen lab, a lab that specializes in insect ecology, integrated pest management and remote sensing.
In the first round, the UC team defeated the Texas A&M undergrads, the defending champions, by 120 to 0. "In the second round, we played Florida (including doctoral candidate David Plotkin, who specializes in the systematics and morphology of emerald moths), and won it in a nail-biting competition down to the last question!" said Boudinot. "Our final round was against the Texas A&M grads."
"Before us, there was a sudden death double overtime game (Texas A&M grads vs University of Delaware) which was really exciting," Boudinot said.
Griebenow recalled that among the questions the UC team correctly answered in the championship round:
Question: The longest-lived lepidopteran is a wooly-bear moth in the Arctiidae. In what habitat would you find these?
Answer: Arctic tundra
Question: The Passandridae are a family of beetles. What is unusual about their larvae?
Answer: The larvae are e ectoparasitoids of wood-boring insects.
The UC Davis Linnaean Games Team, captained by Washington, won the national championship twice, defeating the University of Georgia in 2016 and the University of Florida in 2015. Boudinot served on both championship teams, and Bick, the 2016 team. Last year UC Davis did not compete. Texas A&M won the national championship, with Ohio State University finishing second.
Each ESA branch hosts a Linnaean game competition at its annual meeting. The winning team and the runner-up both advance to the national competition. The national preliminaries took place Sunday, Nov. 11 while the finals got underway at 5 p.m. on Tuesday, Nov. 13.
Members of the winning team will each receive a gold medal and and a plaque for the team's department.
To get to the national finals, the UC team won the regional championship hosted by the Pacific Branch of ESA at its meeting June 10-13 in Reno. They defeated Washington State University in a sudden death overtime to win the title.
Congrats, UC Linnaean Team!

Insects are in. They're not only everywhere in nature (well, almost everywhere!), they've climbed, crawled, jumped, buzzed, fluttered, flew or otherwise positioned themselves on fashions, including the UC Davis Entomology Graduate Student Association (EGSA) t-shirts.
The EGSA, comprised of UC Davis graduate students who study insect systems, is an organization that "works to connect students from across disciplines, inform students of and provide opportunities for academic success, and to serve as a bridge between the students and administration," according to EGSA president Brendon Boudinot, an ant specialist/doctoral student in the Phil Ward lab.
As a year-around fundraising project, they sell t-shirts, which can be viewed and ordered online at https://mkt.com/UCDavisEntGrad/. Jill Oberski, a graduate student in the Phil Ward lab, serves as the t-shirt sales coordinator. She can be reached at firstname.lastname@example.org.
Oberski designed an award-winning onesie, “My Sister Loves Me." It's an adult ant, “loosely based on Ochetellus, a mostly-Australian genus.”
Boudinot's award-winning design is REPRESANT, with illustrations by colleague Eli Sarnat, an alumnus of the Ward lab.
One of the favorite bee t-shirts depicts a honey bee emerging from its iconic hexagonal cells. It's the 2014 winner by then doctoral student Danny Klittich, now a California central coast agronomist.
Another "fave" bee shirt--this one showing a bee barbecuing--is by doctoral student and nematologist Corwin Parker, who studies with Steve Nadler, professor and chair of the UC Davis Department of Entomology and Nematology. It was one of the 2018 winners. (See the three winners on this site.)
EGSA is heading for the Entomological Society of America annual meeting in November. In addition to their participation, the graduate students will be selling shirts at the meeting, appropriately themed "Sharing Insects Globally." It's set for Nov. 11-14 in Vancouver, B.C. The EGSA also sells its t-shirts at other events, including at Briggs Hall during the annual UC Davis Picnic Day.
Insects rock. But some climb, crawl, jump, flutter, buzz, fly or otherwise position themselves on EGSA t-shirts.
Images by three UC Davis-affiliated photographers will be among those displayed at the international Insect Salon photography competition at the Entomological Society of America's meeting, Nov. 11-14 in Vancouver, B.C.
The insect photographers: Alexander Nguyen, who submitted an image of a syprhid fly--a wasp mimic, Ceriana tridens, ovipositing in the fissures of a tree; Allan Jones, a photo of a female leafcutter bee, Megachile fidelis, carrying a leaf petal back to her nest; and Kathy Keatley Garvey, an image of a pollen-drenched honey bee, Apis mellifera, nectaring on mustard.
The images were among 122 accepted for the Insect Salon from a total of 333 images submitted by 84 photographers from 22 countries (a 37 percent acceptance rate).
Nguyen, who received his bachelor of science degree in entomology from UC Davis, is a biologist for the Solano County Department of Agriculture. He captured the image of the wasp mimic at Spanish Flat on the west bank of Lake Berryessa, Napa County. "After larvae hatch they will feed on sap from the tree," said Nguyen, who maintains a photography website at https://alexandernguyen.smugmug.com. Senior insect biosystematist Martin Hauser of the California Department of Food and Agriculture identified the syrphid.
Jones, who holds bachelor's degrees in English and German and a master's degree in English from UC Davis, is a California Department of Agriculture (CDFA) retiree who now resides in Davis. He captured his winning image of the leafcutter bee in the Häagen-Dazs Honey Bee Haven, a half-acre bee garden, operated by the UC Davis Department of Entomology and Nematology and located on Bee Biology Road, west of the central campus. It shows the bee carrying a Clarkia petal back to her nest.
Kathy Keatley Garvey
Garvey, who holds degrees in communications and journalism from Washington State University, Pullman, is a communications specialist with the Department of Entomology and Nematology. She captured her winning image of the pollen-packing honey bee in a Vacaville (Calif.) mustard patch. In her leisure time, Garvey writes a Bug Squad blog, about insects and entomologists, on the UC Agriculture and Natural Resources website, a blog she has written every night, Monday through Friday, for the past 10 years.
