Take the case of a male monarch reared, released and tagged by Steven Johnson in a Washington State University citizen-science project operated by WSU entomologist David James. Johnson tagged and released the monarch on Sunday, Aug. 28, 2016 in Ashland, Ore. Seven days later, on Sept. 5, it fluttered into our family's backyard pollinator garden in Vacaville, Calif., where we photographed it.
"So, assuming it didn't travel much on the day you saw it, it flew 285 miles in 7 days or about 40.7 miles per day," James said. "Pretty amazing." (See Bug Squad blog)
But how do monarchs know when to migrate? You can find out when you attend the UC Davis Bohart Museum of Entomology open house on Saturday, Jan. 18 from 1 to 4 p.m. in Room 1124 of the Academic Surge Building, Crocker Lane.
Doctoral student Yao Cai, a fourth-year doctoral student in the Joanna Chiu lab who studies circadian clocks in insects, will relate how monarchs know when to migrate. “Using Drosophila melanogaster (fruit fly) and Danaus plexippus (monarch butterfly), as models, we seek to understand how these insects receive environmental time cues and tell time, how they organize their daily rhythms in physiology and behavior, such as feeding, sleep and migration (in monarch butterfly)," he says.
Cai is one of six doctoral students who will be showcasing their research. The event is free and family friendly.
Visitors not only will have the opportunity to talk to graduate students about their research and glean information about insects, but will be able see their work through a microscope. In fact, eight microscopes will be set up, Yang said.
In addition to Cai, doctoral students participating and their topics:
Ants: Zachary Griebenow of the Phil Ward lab, UC Davis Department of Entomology and Nematology
Assassin flies: Charlotte Herbert Alberts, who studies with major professor Lynn Kimsey, director of the Bohart Museum, UC Davis Department of Entomology and Nematology
Bats (what insects they eat): Ecologist Ann Holmes of the Graduate Group in Ecology, Department of Animal Science, and the Genomic Variation Laboratory, who studies with major professors Andrea Schreier and Mandi Finger.
Bark Beetles: Crystal Homicz. who studies with Joanna Chiu, UC Davis Department of Entomology and Nematology and research forest entomologist Chris Fettig, Pacific Southwest Research Station, USDA Forest Service, Davis.
Forensic entomology: Alexander Dedmon, who studies with Robert Kimsey, UC Davis Department of Entomology and Nematology
Some doctoral students also will deliver PowerPoint presentations or show slides. The projects:
“Did you know that between 1987 and 2017 bark beetles were responsible for more tree death than wildfire?” asks Crystal Homicz, a first-year doctoral student. “Bark beetles are an incredibly important feature of forests, especially as disturbance agents. My research focuses on how bark beetles and fire interact, given that these are the two most important disturbance agents of the Sierra Nevada. At my table, I will discuss how the interaction between bark beetles and fire, why bark beetles and fire are important feature of our forest ecosystem, and I will discuss more generally the importance of bark beetles in many forest systems throughout North America.
“I will have several wood samples, insect specimens and photographs to display what bark beetle damage looks like, and the landscape level effects bark beetles have. I will also have samples of wood damage caused by other wood boring beetles and insects. My table will focus widely on the subject of forest entomology and extend beyond beetle-fire interactions.”
Visitors, she said, can expect to leave with a clear understanding of what bark beetles are and what they do, as well as a deeper understanding of the importance of disturbance ecology in our temperate forests.
Charlotte Alberts, a fifth-year doctoral candidate, will display assassin flies and their relatives, as well as examples of prey they eat and/or mimic. Visitors can expect to learn about basic assassin fly ecology and evolution. Alberts studies the evolution of assassin flies (Diptera: Asilidae) and their relatives.
“Assassin flies are voracious predators on other insects and are able to overcome prey much larger than themselves,” she said. “Both adult and larval assassin flies are venomous. Their venom consists of neurotoxins that paralyze their prey, and digestive enzymes that allow assassin flies to consume their prey in a liquid form. These flies are incredibly diverse, ranging in size from 5-60mm, and can be found all over the world! With over 7,500 species, Asilidae is the third most specious family of flies. Despite assassin flies being very common, most people do not even know of their existence. This may be due to their impressive ability to mimic other insects, mainly wasps, and bees.”
For her thesis, she is trying to resolve the phylogenetic relationships of Asiloidea (Asilidae and their relatives) using Ultra Conserved Elements (UCEs), and morphology. "I am also interested in evolutionary trends of prey specificity within Asilidae, which may be one of the major driving forces leading to this family's diversity."
Ecologist Ann Holmes, a fourth-year doctoral student, is studying what insects that bats eat. "I will be talking about my research project that looks at insects eaten by bats in the Yolo Bypass. The insects eat crops such as rice, so bats provide a valuable service to farmers. Hungry bats can eat as much as their own body weight in insects each night."
"Visitors can expect to learn how DNA is used to detect insects in bat guano (poop)." "Insects in bat poop are hard to identify because they have been digested, but I can use DNA to determine which insects are there," she said. "We care about which insects bats eat because bats are natural pest controllers. With plenty of bats we can use less pesticide on farms and less mosquito repellent on ourselves."
Zachary Griebenow, a third-year doctoral student, will be showcasing or discussing specimens of the ant subfamily Leptanillinae, most of them male. “I will be showing specimens of the Leptanillinae under the microscope, emphasizing the great morphological diversity observed in males and talking about my systematic revision of the subfamily," he said. "In particular, I want to explain how the study of an extremely obscure group of ants can help us understand the process of evolution that has given rise to all organisms."
Forensic entomologist Alex Dedmon, a sixth-year doctoral student, will display tools and text and explain what forensic entomology is all about. "My research focuses on insect succession. In forensic entomology, succession uses the patterns of insects that come and go from a body. These patterns help us estimate how long a person has been dead. Visitors can expect to learn about the many different ways insects can be used as evidence, and what that evidence tells us."
Other Open House Activities
The family craft activity will be painting rocks, which can be taken home or hidden around campus. "Hopefully some kind words on rocks found by random strangers can also make for a kinder better future,” said Yang.
In addition to meeting and chatting with the researchers, visitors can see insect specimens (including butterflies and moths), meet the critters in the live “petting zoo” (including Madagascar hissing cockroaches, walking sticks and tarantulas) and browse the gift shop, containing books, insect-themed t-shirts and sweatshirts, jewelry, insect-collecting equipment and insect-themed candy.
The Bohart Museum, directed by Professor Lynn Kimsey and founded by noted entomologist Richard M. Bohart (1913-2007), houses a global collection of nearly eight million specimens. It is also the home of the seventh largest insect collection in North America, and the California Insect Survey, a storehouse of insect biodiversity.
The insect museum is open to the public Mondays through Thursdays from 9 a.m. to noon and 1 to 5 p.m., except on holidays. More information on the Bohart Museum is available on the website at http://bohart.ucdavis.edu or by contacting (530) 752-0493 or email@example.com.
They range in topics from fruit flies to spider glue to an African odysssey.

And that's just a small portion of what they do.
And what a difference they're making!
Four UC Davis entomologists won awards from the Pacific Branch, Entomological Society of America (PBESA). They will be honored at the PBESA conference set for March 31-April 2 in San Diego.
Molecular geneticist/physiologist Joanna Chiu won the Physiology, Biochemistry, and Toxicology Award; pollination ecologist Neal Williams, the Plant-Insect Ecosystems Award; doctoral candidate Brendon Boudinot, the John Henry Comstock Graduate Student Award, the highest PBESA graduate student award; and UC Davis doctoral graduate Jessica Gillung, the Early Career Award.
Joanna Chiu is a newly selected Chancellor's Fellow, a five-year prestigious honor given to what Chancellor Gary May calls “prolific scholars, strong teachers, effective mentors and dedicated contributors to campus whose work is novel, unique and cutting-edge, groundbreaking and pathbreaking.”
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.
Among the insects she studies: the spotted-wing drosophila, Drosophila suzukii.
"She has published a considerable amount on the spotted-wing drosophila, including its annotated genome, resistance studies, molecular basis of the so-called ‘winter morphs that are found in colder areas, and a molecular diagnostic for quickly providing species identification for all stages of this pest to distinguish it from other common Drosophila species," said emeritus Frank Zalom, UC Davis distinguished professor of entomology and a past president of the 7000-member Entomological Society of America.
"I can honestly say that in my 40 years on the faculty at UC Davis and earlier at the University of Minnesota, I have
never had the opportunity to work with a more collaborative and energetic early career scientist than Dr. Chiu," Zalom said.
Chiu, along with Professor Jay Rosenheim and associate professor Louie Yang of the UC Davis Department of Entomology and Nematology, are co-founders and co-directors of the highly successful, campuswide Research Scholars Program in Insect Biology. She helps students conduct cutting-edge research and provides guidance and advice, even after they have embarked on their own careers. Under her tutelage, many of her students are first authors of publications in prestigious journals.
Neal Williams "is widely known and respected for his excellence in research, extension, outreach, teaching, leadership and mentoring," said nominator Steve Nadler, chair of the Department of Entomology and Nematology. “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.
Research entomologist James P. Strange of USDA's Bee Biology and Systematics Laboratory at Utah State University, describes Williams as “a valuable resource and prolific scientist in pollination biology and pollinator management. His papers are the result of collaborations with leaders in pollinator ecology, behavior and management and have been cited over 13,000 times during his career. His work has unraveled several questions central to plant-pollinator interactions, especially illuminating our understanding of the impacts of landscape resources on pollinator populations.”
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.
Williams is also organizing a symposium at the PBESA's San Diego meeting in April on the lifelong contributions of native pollinator specialist, Robbin Thorp, UC Davis distinguished emeritus professor of entomology. Nine scientists influenced by Thorp and his research program will speak.
Brendon Boudinot, who studies with ant specialist/professor Phil Ward, 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.
Ward said that Boudinot, despite being at an early stage of his academic career, has already published several landmark papers on insect systematics. "This includes a remarkable article, just published in Arthropod Structure & Development, in which Brendon presents a comprehensive theory of genital homologies across all Hexapoda (Boudinot 2018). Based on careful comparative morphological study and conducted within a phylogenetic framework, this paper is a major contribution to the field and is destined to become a “classic." This could have been a decade-long study by any investigator, and yet it is just one chapter of Brendon's thesis!"
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 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!”
"Not only is Jessica's research on the cutting edge of the field of phylogenomics but--and this is where leadership comes in--she has taken it upon herself to involve and train other graduate students in the same cutting-edge techniques and theoretical framework," Kimsey said. "She is a dynamo--brilliant and high energy, but also constantly teaching."
A native of Brazil, Gillung speaks four languages fluently: Portuguese, Spanish, English and German. While at UC Davis, Gillung was active in PBESA and ESA, presenting a number of presentations and serving on award-winning Linnaean Games teams. In outreach programs, she reached at least 20,000 people encompassing all events from 2013 to 2018. This included open houses, off-site programs, science presentations, summer camps, classroom activities, UC Davis Picnic Days, agriculture days, and fairs and festivals.
As a postdoctoral researcher at Cornell University in the Bryan Danforth lab, Gillung is researching Apoidea (stinging wasps and bees) phylogenomics, evolution and diversification.

Founded in 1889, ESA is the world's largest organization serving the professional and scientific needs of entomologists and individuals in related disciplines. It is comprised of more than 7000 members, who are affiliated with educational institutions, health agencies, private industry, and government. Members are researchers, teachers, extension service personnel, administrators, marketing representatives, research technicians, consultants, students, pest management professionals, and hobbyists.
His seminar, part of the department's weekly seminars, is from 4:10 to 5 p.m., Wednesday, Feb. 13 in 122 Briggs Hall, off Kleiber Hall Drive. The title: "Understanding the Molecular Mechanisms Underlying Photoperiodic Time Measurement in Drosophila melanogaster."
"I will talk about the molecular mechanisms involved in seasonal adaptation in insects," Brieux said. "Overwintering insects undergo profound physiological changes characterized by an arrest in development and reproduction in adults, known as diapause. While the hormonal control of reproductive diapause is relatively well described it is still unclear how organisms interpret variations in photoperiod (daylength) and temperature to modulate their physiology in order to survive through unfavorable seasons."
"In this context I will present the progress we made in the characterization of a key mechanism signaling seasonal changes in insects and how it can promote our understanding of animal seasonal timing in a comparative framework. In addition, future work on this aspect is also expected to have a broad significance in understanding the evolutionary response of pest insects to rapid climate change."
Says Brieux: "Arguably, the most well recognized seasonal response in insects is the induction of overwintering diapause, which can be induced at different life stages, and is characterized by arrest in growth and reproduction. Since PPTM is critical to seasonal adaptation in insects, it has been studied extensively. Yet, the molecular and neuronal basis of the insect photoperiodic timer has evaded characterization."
The overall goal of this study, he says, is "to address the long-standing knowledge gap using the genetically tractable Drosophila melanogaster and the migratory butterfly, the monarch, Danaus plexippus, as complementary model."
"Specifically, we propose to investigate the mechanisms by which the seasonal timer interprets and signals changes in photoperiod to elicit downstream neuroendocrine and physiological responses in insects."
D. melanogaster "continues to be widely used for biological research in genetics, physiology, microbial pathogenesis, and life history evolution," according to Wikipedia. "As of 2017, eight Nobel prizes had been awarded for research using Drosophila."
Brieux received his bachelor's degree in biology in 2009 and pursued a master's degree from Pierre and Marie Curie University, Paris, France. He finished his doctorate in 2014 with faculty members Line Duportets and Christophe Gadenne at Angers University, western France, where he investigated the role of hormones and biogenic amines in the behavioral response to the sex pheromone in the noctuid Agrotis ipsilon.
The postdoctoral scientist joined the Chiu lab in the spring of 2016. In addition to his passion for research, Brieuz is a talented photographer passionate about macrophotography. Check out his photos on his website.
Associate professor Joanna Chiu, a molecular geneticist and physiologist, serves as the vice chair of the UC Davis Department of Entomology and Nematology, and is a newly selected Chancellor's Fellow. Her research expertise involves molecular genetics of animal behavior, circadian rhythm biology, and posttranslational regulation of proteins.
Naoki Yamanaka, an assistant professor at UC Riverside (UCR), is known for his innovative and creative research. In fact, the National Institute of Health (NIH) just awarded him a $2.4 million grant in its High-Risk, High-Reward Research Program to study the role of steroid hormone transporters in insect development and reproduction. A UCR news release pointed out that he will "translate that knowledge into new ways to combat the spread of mosquitoes, which are among the deadliest animals on the plant."
Fast forward to today--actually next week! And this time, it's about fruit flies. Steroid hormone transporters in fruit flies.
Yamanaka will discuss "A Membrane Transporter Is Required for Steroid Hormone Intake in Drosophila" at the UC Davis Department of Entomology and Nematology seminar, set from 4:10 to 5 p.m., Wednesday, Oct. 24, in 122 Briggs Hall. Host is seminar coordinator and medical entomologist Geoffrey Attardo, assistant professor of entomology.
"Steroid hormones are a group of lipophilic hormones that are believed to enter cells by simple diffusion to regulate diverse physiological processes through intracellular nuclear receptors," Yamanaka explains. "We recently challenged this model in the fruit fly Drosophila melanogaster by demonstrating that a membrane transporter that we named Ecdysone importer (Ecl) is involved in cellular uptake of the steroid hormone ecdysone.Eci encodes an organic anion transporting polypeptide of the evolutionary conserved solute carrier organic anion superfamily. Results of our study may have wide implications for basic and medical aspects of steroid hormone research."
Yamanaka, who received his doctorate in biological sciences in 2007 from the University of Tokyo, says that his lab is "focused on identifying and characterizing neuroendocrine signaling pathways that regulate physiological and behavioral changes during insect development. Similar to humans, where physical and mental development during juvenile stage (puberty) is controlled by the neuroendocrine system, insects also have a sophisticated hormone signaling network that regulates their developmental transitions. Mainly by using fruit fly molecular genetic tools, we would like to understand what kind of hormones and receptors are involved in this system, how they work at the molecular level, and how such knowledge can be applied to develop new approaches to control animal development."
This is exciting research.
What exactly are "steroid hormones?" As author Sarah Nightingale explained in the UCR news release:
"Steroid hormones mediate many biological processes, including growth and development in insects, and sexual maturation, immunity and cancer progression in humans. After they are produced by glands of the endocrine system, steroid hormones must enter cells to exert their biological effects. For decades, the assumption has been that these hormones enter cells by simple diffusion, but preliminary work in Yamanaka's lab suggests a defined passageway controlled by proteins called membrane transporters."
Said Yamanaka: "The overall goal of this project is to challenge the conventional paradigm in endocrinology that steroid hormones freely travel across cell membranes by simple diffusion. We will also screen chemicals that inhibit steroid hormone entry into cells, with the goal of developing new pest control reagents.”
The NIH High-Risk, High-Reward Research Program is quite competitive. This year NIH officials granted only 89 awards and they were to “extraordinarily creative scientists proposing highly innovative research to address major challenges in biomedical research.”
Yamanaka's research may lead to important pest control strategies for mosquitoes that transmit deadly diseases. As Nightingale explained: "Using the simple but powerful fruit fly model, his team will study how the insect steroid hormone ecdysone is transported in (and potentially out) of cells with the help of membrane transporters. Since ecdysone controls metamorphosis and molting as an insect moves from one stage of its life cycle to the next, blocking its transport could offer a new way to inhibit insect growth and development. The team will then study the same transport pathway in the mosquito that causes yellow fever, hoping to identify chemicals that inhibit steroid hormone transport as a pest control strategy. Worldwide, mosquito-borne diseases cause millions of deaths each year, with malaria alone causing more than 400,000 deaths, according to the World Health Organization."
Bottom line: “By targeting the membrane transporter from outside the cells, we may be able to circumvent common pesticide resistance machinery provided by proteins within the cells, such as detoxification enzymes and drug efflux pumps,” Yamanaka pointed out in the news release.
His seminar at UC Davis is the fifth in a series of fall seminars coordinated by Attardo. (Note: The Yamanaka seminar will not be recorded.)
