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.
This year's UC team, captained by Ralph Washington Jr., a UC Berkeley public policy graduate student who received his bachelor's degree in entomology at UC Davis, includes five UC Davis doctoral students in entomology: Brendon Boudinot, Zachary Griebenow and Jill Oberski, all of the Phil Ward lab, UC Davis Department of Entomology and Nematology; and alternates Miles Dakin of the Christian Nansen lab and Hanna Kahl of the Jay Rosenheim lab.
Washington has captained all three winning teams, and Boudinot has helped anchor all of them.
The record:
- 2018: UC won the national championship (link to news story) in Vancouver, B.C., defeating Texas A&M Graduates, with Washington captaining the team and joined by Boudinot, Oberski and Griebenow, and Emily Bick (who received her doctorate this year) of the Christian Nansen lab. (No video of the championship round)
- 2017: The UC team did not compete. (Texas A&M won the national championship; see championship round on YouTube)
- 2016: UC won the national and international championships at the University of Florida, at the joint and international meeting of ESA and the International Congress of Entomology (ICE), defeating the University of Georgia. (See championship round on YouTube)
- 2015: UC won the national championship at the games held in Minneapolis, Minn., defeating the University of Florida. (See championship round on YouTube)
All branches of ESA conduct a Linnaean Games competition, with each branch sending the winner and the second-place winner to the nationals. The UC team has won the Pacific Branch (PBESA) competition multiple times. PBESA encompasses 11 Western U.S. states, plus several U.S. territories and parts of Canada and Mexico.
Some of the previous questions asked of the UC team during the championship rounds:

Boudinot co-led the development of the collection with István Mikó, collections manager at the University of New Hampshire Department of Biological Sciences.
For the year-long project. Boudinot and Mikó gathered articles illustrating cutting-edge research techniques in insect morphology and phylogenetics, including videos, interactive 3D images, and augmented reality.
"The increasing availability of advanced technologies, such as micro-computed tomography and confocal laser scanning microscopy, are allowing researchers to generate models of morphology in three and four dimensions based on physical data,” Boudinot wrote in the foreword. “These models not only allow for detailed and quantitative study of anatomical systems and their biomechanical properties, but they also allow end-users to experience the richness of morphology in virtual reality, which is incredible."
Boudinot marvels at the 3D models “which open new pathways of research and which you can manipulate on your computer, and another which can project your model in virtual reality on your phone or tablet.”
Boudinot also wrote an editorial on the future of morphology titled Toward Phylomics in Entomology: Current Systematic and Evolutionary Morphology.
Articles in the collection include:
- A Systematist's Guide to Estimating Bayesian Phylogenies From Morphological Data
- PARAMO: A Pipeline for Reconstructing Ancestral Anatomies Using Ontologies and Stochastic Mapping
- From Spinning Silk to Spreading Saliva: Mouthpart Remodeling in Manduca sexta (Lepidoptera: Sphingidae)
- Jumping and Grasping: Universal Locking Mechanisms in Insect Legs
- Revision of the Highly Specialized Ant Genus Discothyrea (Hymenoptera: Formicidae) in the Afrotropics with X-Ray Microtomography and 3D Cybertaxonomy
- Ready Species One: Exploring the Use of Augmented Reality to Enhance Systematic Biology with a Revision of Fijian Strumigenys (Hymenoptera: Formicidae)
Boudinot said the six papers “span an arc from integrated methods of phenotype observation and visualization to methods and background for phylogenetic modeling of morphological characters.” In his editorial, he reviewed “the central role of anatomical classification and anatomical terminology in systematic by way of outlining the special collection. I argue ultimately for a reconceptualization of phylogenetic morphology.”
Boudinot coined the word, “Phylomics,” which he said “can be defined as the inference of organismal evolution at the molecular and morphological scale, through the use of genomic and phenomic data (the ‘phenome' being a physical model of the phenotype of an organism, such as seen in the ISD special collection). The idea ultimately is to model the morphology of organisms across the phylogeny, through time, literally depicting ancestors and seeing the transformation from ancestor to descendant across the tree of life.”
UC Davis undergraduate student Ziv Lieberman of the Phil Ward lab (he's a senior majoring in evolution and ecology), and Francisco Hita-Garcia of Okinawa (of the Biodiversity and Biocomplexity Unit and Institute of Science and Technology Graduate University), served as the lead authors of “Revision of the Highly Specialized Ant Genus Discothyrea (Hymenoptera: Formicidae) in the Afrotropics with X-Ray Microtomography and 3D Cybertaxonomy.”
Lieberman and Hita-Garcia and three other co-authors described 15 new species in the genus, which is poorly represented in museum collections. Due to its “cryptic lifestyle, Discothyrea are poorly represented in museum collections and their taxonomy has been severely neglected,” they wrote. “We perform the first comprehensive revision of Discothyrea in the Afrotropical region through a combination of traditional and three-dimensional (3D) cybertaxonomy based on microtomography (micro-CT). Species diagnostics and morphological character evaluations are based on examinations of all physical specimens and virtual analyses of 3D surface models generated from micro-CT data.” These models can be seen for free in their article and online at https://sketchfab.com/arilab/collections/discothyrea.
Additionally, they applied “virtual dissections for detailed examinations of cephalic structures to establish terminology based on homology for the first time in Discothyrea. The complete datasets comprising micro-CT data, 3D surface models and videos, still images of volume renderings, and colored stacked images are available online as cybertype datasets (Hita Garcia et al. 2019, http://doi.org/10.5061/dryad.3qm4183).”
The journal, Insect Systematics and Diversity, launched by ESA in 2017, publishes research on systematics, evolution, and biodiversity of insects and related arthropods, including comparative and developmental morphology, conservation, behavior, taxonomy, molecular phylogenetics, paleobiology, natural history, and phylogeography.
The journal set out to host articles that utilize novel technologies or data types or describe emerging methods of research, ESA spokesperson Lisa Junker said. The new special collection on current techniques in morphology, she said, highlights how Insect Systematics and Diversity has become a premier outlet for integrative research combining multiple subdisciplines within the field.

Boudinot presented a talk in Germany at the 9th Dresden Meeting on Insect Phylogeny, hosted by the Senckenberg Institute. In his presentation, "Skeletomuscular Evolution of Male Insect Genitalia, with Emphasis on the Endopterygota," he explained the second chapter of his thesis to an international audience of entomologists, spanning phylogeneticists to anatomists.
At the XXIV Simpósio de Mirmecologia in Belo Horizonte, Minas Gerais, Brazil, Boudinot will present preliminary results from his third and final thesis chapter in a symposium titled "Morphology Reloaded: Conquering the Third Dimension of Ant Evolution and Biogeography." His talk is titled "Altered States: Aculeate Anatomy and the Early Evolution of the Formicoidea."
"While this symposium is focused on the application of scanning technologies, such as X-ray computed microtomography, I will be speaking about the evolution of ant morphology through evolutionary time," Boudinot related. He will be presenting results from combined phylogenetic analysis of genome-scale DNA sequence data and a massive dataset of 576 morphological characters scored for 573 species.
"One of the novel aspects of my study is how many fossils I have included (more than 300)," Boudinot said. "The objective of this particular work is to estimate the geological age in which the ants originated, as well as the physical features of the ancestral ant, which I will then use to trace evolutionary and paleoecological patterns to the modern fauna."
Boudinot received the prestigious John Henry Comstock Award in April at the Pacific Branch, Entomological Society of America (PBESA) meeting in San Diego. This is the highest graduate student award given by PBESA, which encompasses 11 Western states, U.S. territories, and parts of Canada and Mexico. Its parent organization, the Entomological Society of America (ESA), will honor the six Comstock award winners--one from each branch--at its Nov. 17-20 meeting in St. Louis.
Boudinot, who was praised for his academic record, leadership, public service activities, participation in professional activities, and his publications, is the sixth UC Davis recipient of the Comstock award:
2019: Brendon Boudinot (major professor Phil Ward)
2015: Mohammad-Amir Aghaee (major professor the late Larry Godfrey)
2014: Kelly Hamby (major professor Frank Zalom)
2013: Matan Shelomi (major professor Lynn Kimsey)
2008: Christopher Barker (major professor William Reisen)
1983: Elaine Backus (major professor the late Donald McLean)
Active in PBESA and ESA, Boudinot received multiple “President's Prize” awards for his research presentations at national ESA meetings. He organized the ESA symposium, “Evolutionary and Phylogenetic Morphology,” at the 2018 meeting in Vancouver, B.C. , and delivered a presentation on “Male Ants: Past, Present and Prospects” at the 2016 International Congress of Entomology meeting in Orlando, Fla.
Boudinot served on—and anchored—three of the UC Davis Linnaean Games teams that won national or international ESA championships. The Linnaean Games are a lively question-and-answer, college bowl-style competition on entomological facts played between university-sponsored student teams.
Boudinot has served as president of the UC Davis Entomology Graduate Student Association since 2006, and is active in the campuswide UC Davis Picnic Day; he has co-chaired the department's Picnic Day Committee since 2017.

The UC Davis recipients, as announced today:
Molecular geneticist/physiologist Joanna Chiu, vice chair of the department, associate professor and Chancellor's Fellow, won the Physiology, Biochemistry, and Toxicology Award. The annual award is presented to an individual who has an outstanding record of accomplishment in at least one of the entomological sub-disciplines of physiology, biochemistry, and toxicology.
Pollination ecologist Neal Williams, professor, won the Plant-Insect Ecosystems Award. The annual award is given to an individual with outstanding accomplishments in the study of insect interrelationships with plants.
Doctoral candidate and ant specialist Brendon Boudinot who studies with Professor Phil Ward, won the 2019 John Henry Comstock Graduate Student Award, the top graduate student award. This award is based on academic record, leadership, public service activities, participation in professional activities, and publications.
They will be honored at PBESA's 103rd annual meeting, to take place March 31 - April 3 in San Diego, California.
The University of California accounted for eight of the 12 PBESA awards, with UC Davis winning four, UC Riverside, three, and the UC Agriculture and Natural Resources (UC ANR), one.
Joanna Chiu, Physiology, Biochemistry, and Toxicology Award
"Dr. Chiu not only excels in unique and cutting-edge research, both basic and applied, but has distinguished herself in mentoring, teaching and service contributions,” said Steve Nadler, professor and chair of the UC Davis Department of Entomology and Nematology, who nominated her for the award.
She studies how genes and proteins regulate animal physiology and behavior in response to changes in environment and resources. Her research involves molecular genetics of animal behavior, circadian rhythm biology, and posttranslational regulation of proteins. Major grants from the National Institutes of Health and the National Science Foundation fund her research.
Chiu investigates the regulation of animal circadian rhythms in her laboratory by using a combination of molecular genetics, biochemical, genomic, proteomic, and metabolomic approaches. Her overall research goal: to dissect the molecular and cellular mechanisms that control the circadian clock in animals, and to investigate how this endogenous timer interacts with the environment and cellular metabolism to drive rhythms of physiology and behavior.
Neal Williams, Plant-Insect Ecosystems Award
"Dr. Williams is widely known and respected for his excellence in research, extension, outreach, teaching, leadership and mentoring," said Nadler. “He is a leading voice in the development of collaborative research on insect ecology. He has organized national and international conferences, leads scores of working groups, and guides reviews of impacts of land use and other global change drivers on insects and the services they provide.”
Williams focuses his research on the ecology and evolution of bees and other pollinator insects and their interactions with flowering plants. His work is particularly timely given concern over the global decline in bees and other pollinators.
In July, Williams will co-chair the Fourth International Conference on Pollinator Biology, Health and Policy at UC Davis. The four-day conference, themed “Multidimensional Solutions to Current and Future Threats to Pollinator Health,” will highlight recent research advances in the biology and health of pollinators, and link to policy implications.
Brendon Boudinot, John Henry Comstock Graduate Student Award
Brendon Boudinot was praised for his academic record, leadership, public service activities, participation in professional activities, and his publications. “A highly respected scientist, teacher and leader with a keen intellect, unbridled enthusiasm, and an incredible penchant for public service, Brendon maintains a 4.00 grade point average; has published 12 outstanding publications on insect systematics (some are landmarks or ground-breaking publications); and engages in exceptional academic, student and professional activities,” Nadler wrote.
Active in PBESA and ESA, Boudinot received multiple “President's Prize” awards for his research presentations at national ESA meetings. He organized the ESA symposium, “Evolutionary and Phylogenetic Morphology,” at the 2018 meeting in Vancouver, B.C. , and delivered a presentation on “Male Ants: Past, Present and Prospects” at the 2016 International Congress of Entomology meeting in Orlando, Fla.
Boudinot served on—and anchored—three of the UC Davis Linnaean Games teams that won national or international ESA championships. The Linnaean Games are a lively question-and-answer, college bowl-style competition on entomological facts played between university-sponsored student teams.
Boudinot has served as president of the UC Davis Entomology Graduate Student Association since 2006, and is active in the campuswide UC Davis Picnic Day; he has co-chaired the department's Picnic Day Committee since 2017.
Jessica Gillung, Early Career Award
Jessica Gillung studied for her doctorate with major professor Lynn Kimsey, director of the Bohart Museum of Entomology and professor of entomology. “Dr. Gillung has made outstanding contributions to entomology, shown commitment to extension or outreach, and excelled in entomological education,” Kimsey wrote in her letter of nomination. “In one word: she is ‘phenomenal.' Gillung most recently won the “Best Student Presentation Award” at the ninth annual International Congress of Dipterology, held in Windhoek, Namibia, and the 2018 PBESA Student Leadership Award. Her dissertation was titled: “Systematics and Phylogenomics of Spider Flies (Diptera, Acroceridae).”
Kimsey praised her phenomenal leadership activities, her nearly straight-A academic record (3.91 grade point average), her excellence as an entomologist and teacher, and her incredible publication record. “Note that she has 11 refereed publications on her thesis organisms in very strong journals,” Kimsey wrote. “Most entomologists do not publish nearly that much, even as a postdoctoral scholar or a junior faculty member!”
As a postdoctoral researcher at Cornell University in the Bryan Danforth lab, Gillung is researching Apoidea (stinging wasps and bees) phylogenomics, evolution and diversification.

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.
"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:
Answer: Arctic tundra
Question: The Passandridae are a family of beetles. What is unusual about their larvae?
Answer: The larvae are ectoparasitoids of wood-boring insects.
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.
