Ask her why people should be interested in insects, and she'll tell you. There's no "yecch" factor here: just the "ahh!" and "wow" factors.
Which is as it should be!
"First of all, bugs are just really cool!" says Sol, in her third year as an entomology major. "Second, they are extremely important in just about every aspect of life, even if most people don't like to think about that. Just as an example, almost all the food we eat was either directly or indirectly insect-pollinated. Fruits are obvious, but even all the meat we eat comes from animals that ate plants that were pollinated by insects. My field of study, wild bees, is especially important in this exact context because they cannot pollinate every crop. For example, alfalfa and tomatoes are two of our most common crops that cannot be pollinated by honey bees."
Sol, who grew up in the Bay Area community of Belmont, is the first entomologist in her family. "My parents and brother all love insects, but I am the only one hoping to make a career out of entomology. My dad is a forensic economist, my mom is a photographer, and my brother works as a distributor in the car wash industry."
What sparked her interest in entomology?
The UC Davis Entomology Club draws about 25 people to its weekly meetings, held on Thursdays at 6 p.m. in 122 Briggs Hall. (See Instagram account). "But this quarter a few of our meetings have had 40-plus," Sol said. "Every week, I lead a bug-themed activity, which ranges from professional pinning demos, guest speakers, and arboretum field trips, to movie nights, bug-themed trivia, and show-and-tell nights. At least once or twice a quarter, we do an overnight camping trip in Pope Valley to look for bugs. This fall, our camping trip had 25 insect-enthusiasts, which was a ton of fun but definitely a hassle for me to plan!"
Sol is passionate about her research. In the Williams lab, she is working on a project led by graduate student Elizabeth Reyes-Gallegos that is focused on comparing the functional traits of wild bees to floral functional traits. "Early this quarter, we finished our first field season sampling at plots at the Bee Biology Facility (Harry H. Laidlaw Jr. Honey Bee Research Facility on Bee Biology Road), so we are still in the early stages of the project," Sol said. "Since spring quarter, I have been working very closely with just about every bee we have collected because I have been dissecting their proboscises as well as pinning and labeling them. Because I have worked so closely with the bees' 'tongues,' I will be branching off slightly from Elizabeth's main focus to look for intraspecific variation in tongue lengths and body size. Currently, I am working closely with Elizabeth and Neal to fully flesh out this project."
At the Bohart Museum, Sol is involved in general curation: pinning, labeling and integrating specimens into the collections. She is currently organizing the Orthoptera collection, which includes grasshoppers, locusts, and crickets. And she's beginning species identification of katydids (Tettigoniidae).
Sol is a fixture at the Bohart Museum open houses. "I started volunteering with the Bohart in winter of 2022 at the Biodiversity Museum Day," she related. "In the months following that, I became a regular volunteer at their outreach events. This was also before I became president of the Entomology Club, but during that time I was helping out as much as I could with various club outreach opportunities, like birthday parties or campus festivals. In July of 2022, the Bohart hired me as an undergraduate intern and I have been working there ever since!"
Another project: Sol is spearheading the Bohart Museum's open house on "Grasshoppers, Crickets and Katydids," from 1 to 4 p.m., Sunday, March 3 in Room 1124 of the Academic Surge Building, 455 Crocker Lane, UC Davis campus. (See Bohart Museum schedule)
How would she describe herself to a stranger? "I am an ambitious, hard-working, and outgoing future career entomologist with a special interest in wild bees and katydids. I love to explore the outside looking for bugs, and have dreams of traveling the world for that very purpose. When I don't have insects on my mind, I like to spend my time playing violin, drawing, and surrounding myself with my friends and family."
She's played the violin for about 11 years; in high school she volunteered to teach fourth and fifth graders how to play the instrument.
Sol is glad she chose UC Davis to study entomology. "Overall, I really like how UC Davis is inclusive and welcoming. I also love that we have the arboretum, which has some really great places to find bugs. And of course, I'm especially glad that entomology is a major here and I absolutely love the little entomologist community we've built."
From a childhood loving insects to a senior majoring in entomology at UC Davis, to a researcher studying wild bees to a curator working in the Orthoptera collection at the Bohart Museum, what's next?
"After I graduate from UC Davis, I would like to go to graduate school and study systematics," Sol related. "Although I am also extremely interested in ecology, I have developed an interest in systematics and museum work over the last year. Ultimately, I think I would like to become a professor of entomology and maybe someday run my own lab."
Professor Sol Wantz...That has a nice ring to it!

Stuligross, who received her doctorate in ecology on Sept. 9 from UC Davis, will present her exit seminar, "Individual and Combined Effects of Resource and Pesticide Stressors on Wild Bees and a Potential Strategy to Mitigate Impacts" at 10 a.m., Tuesday, Oct. 18 in Room 1022 of Green Hall.
The seminar, open to all interested persons, also will be virtual. The Zoom link is https://ucdavis.zoom.us/j/3661107142.
Stuligross researches nutrition and pesticide exposure and their comparative effects on the blue orchard bee, Osmia lignaria, and the yellow-faced bumble bee, Bombus vosnesenskii. Pollination ecologist Neal Williams, professor in the Department of Entomology and Nematology, served as her major professor.
"I am doing a short postdoc with Neal Williams this fall, and in January I will start a postdoctoral research position with Nicole Rafferty at UC Riverside," Stuligross said.
"Anthropogenic environmental changes present multiple stressors that together impact biodiversity and ecosystem function," Stuligross writes in her abstract. "Among these, pesticide exposure and the loss of flowering plants are ubiquitous across contemporary landscapes and threaten the persistence of bee populations. In this dissertation, I explored the individual and combined effects of pesticide and floral resource stressors on bee behavior, reproduction, and population persistence, as well as a potential strategy for mitigating these impacts. I used a combination of manipulative field cage experiments and landscape studies to examine these stressors and their impacts at different scales.
"Because bees often experience pesticide and resource stressors simultaneously, I first examined the potential for interactive effects of these stressors, as well as their individual impacts on wild bees. I established a fully crossed design in field cages; nesting female Osmia lignaria, the solitary blue orchard bee, accessed wildflowers at high or low densities, treated with or without the common insecticide, imidacloprid. In Chapter 1, I showed that pesticide exposure and floral resource scarcity combined additively to dramatically alter multiple vital rates, including reduced reproduction and a male-biased offspring sex ratio. In Chapter 2, I quantified behavioral responses in the same experiment, revealing that the resource and pesticide stressors had differential impacts with consequences for bee populations and potentially for pollination services through individual behavioral changes. Limited floral resources required bees to make fewer, longer foraging trips as well as misidentify their nests more often upon return from these trips. Bees exposed to pesticides made shorter foraging trips and did not compensate for this by taking more trips, reducing their overall foraging activity. Pesticide exposure also interacted with age to affect antagonistic behavior."
"In Chapter 3, I examined the carryover effects of past pesticide exposure on wild bees. Using the offspring from the previous cage experiment with known pesticide exposure backgrounds, I re-established the field cages and released bees in a crossed design with pesticide exposure or no exposure in each year. Thus, some bees experienced pesticides over two generations and others not at all. Regardless of the past exposure history, pesticides in the second year reduced reproduction. For bees that were also exposed in the past, the exposure over two years additively impaired individual performance, leading to a nearly fourfold estimated reduction in bee population growth. Furthermore, even past exposure by itself, regardless of exposure in the second year, led to a decline in offspring production."
"In Chapter 4, I collaborated with Maj Rundlöf to investigate the potential for wildflower plantings to mitigate the negative effects of pesticide exposure in agricultural landscapes. We assessed the nesting and reproduction of O. lignaria and the bumble bee Bombus vosnesenskii in replicate agricultural landscapes, half of which contained a wildflower planting next to the nest or colony. We collected pollen from foraging bees to determine resource use and pesticide residues. The wildflower plantings were a source of pesticide exposure, especially for O. lignaria, but also supported O. lignaria nesting. The landscape-level floral resources better predicted B. vosnesenskii colony success, but the local flower resources mitigated the negative effects of pesticides on their reproduction."
"These chapters together show that two common environmental stressors combine to negativel impact bees. They also reveal potential mechanisms underlying impacts of the stressors on reproduction and population growth. My dissertation highlights the importance of mitigating the negative effects of pesticides and floral resource limitation, especially in agricultural landscapes where the two stressors often co-occur. Finally, this work offers insight into how the stressors could be mitigated through an emerging strategy to diversity agricultural landscapes."
Stuligross received her bachelor of arts degree in environmental studies in 2014 in Indiana from Earlham College, Richmond, where she minored in biology and outdoor education. At UC Davis, she was awarded a 2017-22 National Science Foundation Graduate Research Fellowship, and a 2016-18 UC Davis Graduate Group in Ecology Fellowship.
Recognized nationally for her research, Stuligross scored second place in the Entomological Society of America's 2020 President's Prize competition. Her research posters also won the top award at the UC Davis Graduate Student Symposium in Ecology in both 2019 and 2021.
Stuligross and her colleague, Maj Rundlöf, are the co-first authors of "Flower Plantings Support Wild Bee Reproduction and May Also Mitigate Pesticide Exposure Effects," published in May 2022 in the Journal of Applied Ecology. She was the lead author of "Past Insecticide Exposure Reduces Bee Reproduction and Population Growth Rate," published in November 2021 in the Proceedings of the National Academy of Sciences, and also the lead author of "Pesticide and Resource Stressors Sdditively Impair Wild Bee Reproduction," published in September 2020 in The Proceedings of the Royal Society B.
Stuligross has also co-authored a number of other research publications, most recently:
- "A Meta-Analysis of Single Visit Pollination Effectiveness Comparing Honeybees and Other Floral Visitors," American Journal of Botany
- "Impact of 'Nonlethal' Tarsal Clipping on Bumble Bees (Bombus vosnesenskii) May Depend on Queen Stage and Worker Size," Journal of Insect Conservation
Want to learn more about wild bees, also known as undomesticated bees? Be sure to read the UC-authored book, California Bees and Blooms: A Guide for Gardeners and Naturalists. It's the work of Gordon Frankie of UC Berkeley, the late Robbin Thorp of the UC Davis Department of Entomology and Nematology; Barbara Ertter of UC Berkeley; and photographer Rollin Coville, alumnus of UC Berkeley. California is home to more than 1600 species of undomesticated or wild bees.

If you've observed honeybees and wild bees foraging in your garden, you've probably wanted to compare them. Is the honey bee the most effective pollinator?
Newly published UC Davis research in the American Journal of Botany yields some surprising results.
Honeybees are effective pollinators, but when compared to other pollinators, including wild bees, they are rarely the most effective plant pollinators, according to a meta-analysis project led by doctoral candidate Maureen Page and postdoctoral researcher Charlie Casey Nicholson of the Neal Williams laboratory, UC Davis Department of Entomology and Nematology.
Page and Nicholson are the co-leading authors of "A Meta-Analysis of Single Visit Pollination Effectiveness Comparing Honeybees and other Floral Visitors," the cover story of the current edition of the journal, published Nov. 30.
“Although high visitation frequencies make honeybees important pollinators, they were rarely the most effective pollinators of plants and were less effective than the average bee,” said Page. “This suggests that honeybees may be imperfect substitutes for the loss of wild pollinators and ensuring pollination will benefit from conservation of non-honeybee taxa. In the future, we hope other researchers will use the data we have collected to further investigate the factors that influence pollination effectiveness.
Page and Nicholson originated the idea for the project during a graduate seminar led by UC Davis professor and community ecologist Louie Yang in the winter of 2020. While the COVID-19 pandemic shut down or postponed many other research projects, Page and Nicholson forged ahead and organized fellow graduate students and postdoctoral students to collectively read and extract single visit-effectiveness data from more than 468 papers. The two then analyzed the data from a subset of these papers (168) to ask whether honeybees and other floral visitors differed in their single visit pollination effectiveness.
The researchers conducted a hierarchical meta-analysis of 168 studies and extracted 1564 single visit effectiveness (SVE) measures for 240 plant species. “We paired SVE data with visitation frequency data for 69 of these studies,” they wrote. “We used these data to ask three questions: (1) Do honeybees (Apis mellifera) and other floral visitors differ in their SVE? (2) To what extent do plant and pollinator attributes predict differences in SVE between honeybees and other visitors? (3) Is there a correlation between visitation frequency and SVE?”
They compared honeybees to multiple pollinator groups, including ants, bees, beetles, birds, butterflies, flies, moths, and wasps.
"Surprisingly, honeybees were less effective than other bees as pollinators of crop plants, suggesting that the importance of honeybees as crop pollinators derives largely from their numerical abundance rather than the quality of their floral visits," Page said.
“Honeybees were significantly less effective than the most effective non-honeybee pollinators but were as effective as the average pollinator," they wrote in their results section of the paper. "The type of pollinator moderated these effects. Honeybees were less effective compared to the most effective and average bird and bee pollinators but were as effective as other taxa. Visitation frequency and SVE were positively correlated, but this trend was largely driven by data from communities where honeybees were absent.”
Also contributing to the project were Ross Brennan, Anna Britzman, Jessica Greer, Jeremy Hemberger, Hanna Kahl, Uta Müller, Youhong Peng, Nick Rosenberger, Clara Stuligross, Li Wang, and Professors Louie Yang and Neal Williams.
Cover Photo. The cover photo, by Kathy Keatley Garvey, communications specialist, UC Davis Department of Entomology and Nematology, shows several species of bees on a sunflower, Helianthus sp. They include a honeybee (Apis mellifera), sunflower bee (Svastra obliqua), and two sweat bees (Halictus tripartitus and Halictus ligatus), as identified by Professor Williams, a pollinator ecologist.
"Honeybees are as effective as the average pollinator, but rarely the most effective pollinators of plants," according to the caption. "Surprisingly, honeybees are less effective than other bees as pollinators of cultivated plants, suggesting the importance of honeybees as agricultural pollinators derives largely from their numerical abundance. Their study confirms a widely held belief that honeybees are not the best pollinators of plants globally and substantiates the growing concern that honeybees may be imperfect substitutes for the loss of wild pollinators."
Charlie Nicholson. Nicholson, a researcher in the UC Davis Department of Entomology and Nematology labs of both Professor Neal Williams, and Extension apiculturist Elina Lastro Niño, holds a bachelor of arts degree in biology (evolution, ecology and behavior), 2010, cum laude, from Skidmore College, Saratoga Springs, New York. He received his doctorate in natural resources in 2018 from the University of Vermont, where he was a Gund Institute for Environment graduate fellow. In his dissertation, he examined how landscape and farm management affect the multiple benefits provided by wild bees.
Nicholson joined UC Davis as a postdoctoral scholar in the spring of 2019, and receives funding support from the USDA Invasive Species and Pollinator Health Unit. He recently co-authored a paper, “Natural Hazard Threats to Pollinators and Pollination,” published in the journal Global Change Biology, that analyzed 117 published research papers on natural hazards that threaten pollinators and pollination.
Maureen Page. Page received her bachelor's degree in biology, cum laude, from Scripps College, Claremont, Calif., in 2016, and then enrolled in the UC Davis entomology graduate program, with a career goal of becoming a professor and principal investigator. In 2018, she received prestigious three-year fellowship, a National Defense Science and Engineering Graduate Fellowship, for her research proposal, “Promoting Food Security by Optimizing Wildflower Plantings to Support Wild and Managed Bees." Long interested in bee research, Page received a 2013 Scripps Environmental Research Grant to establish a solitary bee monitoring program at the Bernard Field Station in Claremont. She created a reference collection and species list of bee diversity at the field station, gaining experience collecting, pinning and identifying bee specimens. She presented her findings at the Scripps Undergraduate Research Symposium. Page later worked on a project categorizing pollen deposition by the yellow-faced bumble bee, Bombus vosnesenkii to California figwort, Scrophularia california.

Egerer will speak on "Entomological Investigations in Urban Gardens," focusing on wild bees and natural enemies in urban gardens in Germany, at a virtual seminar hosted by the UC Davis Department of Entomology and Nematology on Wednesday, Nov. 24.
Her seminar begins at 4:10 p.m., Pacific Time. The Zoom link is here.
More than 60 percent of our world's population will live in cities in the next decades, Egerer says in her abstract. "Urban agriculture has great potential to support arthropod biodiversity and thereby potentially enhance ecosystem services such as pollination and pest predation for more sustainable food production. In this talk, I discuss interdisciplinary research on wild bees and natural enemies in urban community gardens in Berlin and Munich, Germany. Specifically, I examine how urban garden management can play an important role in supporting species diversity and the provision of insect-mediated services. Furthermore, I discuss citizen science initiatives that our group uses to engage the public in scientific research on urban biodiversity and ecosystem services."
Egerer, whose research and teaching interests include ecology, biodiversity, agroecology, urban ecology, insect ecology, climate change, and food systems, holds a bachelor's degree in biology (2013) from Kalamazoo College, Mich., and then received her master's degree (2017) and her doctorate (2019) in environmental studies from UC Santa Cruz, studying with major professor Stacy Philpott.
After research work in Australia, Egerer joined the Institute of Ecology at the Technical University of Berlin in 2019 as an International Postdoc Initiative (IPODI) postdoctoral fellow. In 2020, she was appointed to the professorship for Urban Productive Ecosystems in the TUM School of Life Sciences.

She spoke on "The Importance of People in Pollinator Conservation" to a capacity crowd gathered July 18 in the ARC Ballroom.
“Who needs to act?" she asked. "Farmers, governments, conservationists, researchers, the general public and businesses.”
Quoting noted biologist/author E. O. Wilson, Dicks said that insects are “the little things that run the world.”
Dicks began her presentation by chronicling news media accounts of “insectageddon,” which Cambridge fellow Robert Macfarlane defined on Twitter as “the current calamitous population decline of insect species globally, with catastrophic results for life on earth.”
One news story, by environment editor Damian Carrington of The Guardian, warned that "The world's insects are hurtling down the path to extinction, threatening a catastrophic collapse of nature's ecosystems." Carrington, in his Feb. 10, 2019 piece, titled “Plummeting Insect Numbers ‘Threaten Collapse of Nature," wrote that “More than 40 percent of insect species are declining and a third are endangered...The rate of extinction is eight times faster than that of mammals, birds and reptiles. The total mass of insects is falling by a precipitous 2.5% a year, according to the best data available, suggesting they could vanish within a century.”
“Wild insect pollinators have declined in occurrence, diversity, and in some cases, abundance, in Europe and North America,” Dicks told the crowd. “Lack of data for other regions prevents global assessment of status for insect pollinators, but the main drivers of decline are operating everywhere.”
“Why does pollinator decline matter?” she asked. “Eighty-eight percent of wild plant species depend on pollinators. At least half of the crop pollination serves are provided by wild pollinators—half by managed honey bees.”
Farmers, governments, conservationists, researchers, the general public and businesses must get involved, she reiterated.
What Farmers Should Do
For example, she said, farmers should
- Plant flowers for nectar and pollen
- Manage hedges and forest edges for wildlife
- Restore and protect flower-rich native habitats like meadows, scrubland and woodland
- Provide set aside or fallow areas
- Leave field edges and corners to naturally generate
- Provide nesting sites for bees ("bare ground, big old trees and bee hotels")
What the General Public Should Do
The general public's role should be:
- Grow more flowers, shrubs and trees
- Let your garden grow wild
- Cut your grass less often
- Don't disturb insect nest and hibernation spots
- Think carefully about whether to use pesticides
What Governments Should Do
Dicks touched on 10 "pollinator policies" that governments should do:
- Raise pesticide regularly standards
- Promote integrated pest management
- Include indirect and sublethal effects in GM crop risk assessment
- Regulate movement of managed pollinators
- Develop incentives, such as insurance schemes, to help farmers benefit from ecosystem services instead of agrochemicals
- Recognize pollination as an agricultural input in a extension services
- Support diversified farming systems
- Conserve and restore 'green infrastructure” (a network of habitats that pollinators can move between) in agricultural and urban landscapes
- Develop long-term monitoring of pollinators and pollination
- Fund participatory research on improving yields in organic, diversified and ecologically intensive farming
Dicks, in her position at the University of East Anglia, engages in research in entomology, agroecology, management of biodiversity and ecosystem services on farms. (See research profile.)
In addition to addressing pollinator decline and "who needs to act and what should they do," the researcher touched on how to motivate people: "insights from the behavioral sciences; and the importance of local knowledge and culture."
Awareness and Understanding Are Not Sufficient
She offered key insights from behavioral science, noting that "awareness and understanding are not sufficient; decisions are not always rational; social norms are important; peer-to-peer communication within social groups drives behavior change and people must feel ABLE to act in their current context."
Dicks recommended that the attendees become acquainted with the work of the coalition Promote Pollinators (https://promotepollinators.org). An excerpt from the website: "Pollinators play a key role in the conservation of biological diversity, ecosystems, food production and the global economy. The effects of current human activities hamper animal pollination. Promote Pollinators, the Coalition of the Willing on Pollinators, reaches out to potential new partners to develop and implement national pollinator strategies. The coalition believes that country-led politics can foster policy measures and innovative action on protecting pollinators."
She also cited the work of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES)
Dicks described pollinator decline as "a complex issue." People--including some politicians--have to change to help protect the pollinators and the ecosystem.
How Some Politicians Use Science
Dicks quoted author Mark Avery, former director of conservation at the Royal Society for the Protection of Birds: "I have rarely seen a policy argument won through logic and science, even though everybody pretends that they are. No, politicians use science like a drunk uses a lamp post--more for support than for illumination."
The conference, “Multidimensional Solutions to Current and Future Threats to Pollinator Health,” covered a wide range of topics in pollinator research: from genomics to ecology and their application to land use and management; to breeding of managed bees; and to monitoring of global pollinator populations. (See agenda.)
Dicks keynoted the conference on Thursday morning, July 18, and Christina Grozinger, distinguished professor of entomology and director of the Center for Pollinator Research, Pennsylvania State University, delivered a keynote address on Friday, July 19, discussing "Bee Nutritional Ecology: From Genes to Landscapes."
Pollination ecologist and professor Neal Williams and Extension apiculturist Elina Lastro Niño, both of the UC Davis Department of Entomology and Nematology, co-chaired the conference. Amina Harris, director of the UC Davis Honey and Pollination Center, and events manager Elizabeth Luu coordinated the four-day event.
Presenters from 15 Countries
Williams said that presenters represented 15 countries: Australia, Thailand, Korea, Japan, Colombia, Brazil, Israel, Mexico, France, Germany, Spain, Sweden, United Kingdom, Canada, and the United States. "And we had at least one attendee from China--although not presenting."
"This was the fourth International Conference on Pollinator Biology, Health and Policy," Williams said. "Each time we try to add new elements that address emerging challenges and new directions in research. This year's sessions felt as fresh and innovative as ever, adding symposia on climate change, innovative monitoring and data collection, and urban bees. By restricting presenters to those who had not presented in the past six years we also added new voices and perspectives."
"We also grew. In the past the conference has been just under 200 attendees. This year it topped 250, and we had to turn away several people because we simply could not fit more into the space. We added a second evening of posters to provide more time to interact. The response was overwhelming with 112 poster presenters!"
Williams said that the conference "also added more explicit policy elements by creating a set of ViewPOINTS documents summarizing key areas in pollinator biology and heath that target policy makers. This has allowed for collaborative interaction across the attendees and a set of deliverable products from our interactions."
The UC Davis Honey and Pollination Center, directed by Amina Harris, coordinated the conference, with events manager Elizabeth "Liz" Luu serving in the lead role.
"It was an amazing team effort pulling it all together," Williams said. "Liz Luu from the UC Davis Honey and Pollination Center (HRC) was in a word, fantastic, keeping every thing and everyone together. The HPC really showed what it can do and what tremendous value it adds to our campus. The organizing committee worked so well together, sharing the load throughout. A great set of colleagues!"
The next International Pollinator Conference will take place at Pennsylvania State University. Grozinger and Rufus Isaacs of Michigan State University launched the conference in 2012. They are held every third year.
