The goal is "to advance the land management aims of local tribal communities and provide a platform to educate about the importance of maintaining wetland biology for climate change, ecological and human health, and vector control,” announced medical entomologist-geneticist Geoffrey Attardo, associate professor, UC Davis Department of Entomology and Nematology.
The symposium is sponsored by the UC Davis Department of Entomology and Nematology and the Pacific Southwest Center of Excellence in Vector-Borne Diseases, which aims to “strengthen the capacity to prevent and respond to emerging vector-borne diseases in the southwestern United States and Pacific Islands.”
His collaborator is Diana Almendariz, a traditional ecological knowledge specialist and a cultural practitioner of Maidu/Wintun,Hupa/Yurok traditions, heritage, and experiences. She will discuss the precolonial relationships between native peoples and wetlands in Northern California, the impacts of colonization on those relationships, and the application of traditional ecological knowledge practices to restore damaged wetland ecosystems. (See video of her talking about her goals at https://www.youtube.com/watch?

The emeriti celebrations are the brainchild of UC Davis distinguished professor Walter Leal of the Department of Molecular and Cellular Biology (and former professor and chair of the Department of Entomology). He organizes and hosts the events in the International Center.
The recent emeriti celebration honored 73 faculty who retired in the 2022-2023 cohort. Some discussed their research.
Shapiro titled his talk "Using Butterflies to Understand Biotic Responses to Climate Change."
Shapiro, who holds a bachelor's degree in biology from the University of Pennsylvania (1966) and doctorate in entomology from Cornell University (1970), began his UC Davis career in 1972 with the Department of Entomology. He recently retired from the UC Davis Department of Evolution and Ecology faculty, but continues his research with his former doctoral student, Professor Matt Forister of the University of Nevada.
Shapiro maintains a research website at https://butterfly.ucdavis.edu. Some excerpts from his slide show presentation:
How It All Began
In 1972, as a new assistant professor, I inaugurated what was supposed to be a 5-year study of butterfly phenology (seasonality) in an attempt to identify which weather variables had the greatest impact on the life-history “strategies” of species.
Why Five Years?
- That would give me enough variability for statistical analysis, using multivariate methods, and
- Given the time frame for my tenure decision, it would allow me to finish the project in case I had to leave.
- I got tenure. And I kept on gathering data!
Why Keep Going?
If you were here in the early 1970s, you'll recall that the climate was extraordinarily variable. That was great for me; the more year-to-year variation, the more could be teased out statistically about climate-life history correlations.
The variability continued, and the data were so good I didn't dare stop collecting them. What started as a 5-year project became a 45-year project!
At that time there was only one other longterm butterfly monitoring project in the world—in the U.K., started at the same time.
I started out trying to understand the climatic basis for “voltinism”—the number of generations (broods) per year--and the way each species spent what is for it the “adverse season.” But once I had several years of data a new question arose: what determines the “first flight date” (FFD) of a species in a given year?
This Graphic Illustrates Why I Kept Going
Look carefully at it! What pattern strikes your eye?
If you have studied statistics, you may have learned about "time series analysis," which is used to extract information from long series of repeated data or measurements.
An important idea here is the distinction between "signal" and "noise." Noise is short-term variability. Signal is longer-term trend.
There's lots of noise on this annual-rainfall plot, but is there any signal? To answer that, we need to look at more than one time frame. By inspection--the stats bear it out--the first third of this data set was extremely noisy and the last third nearly as much so.
The middle third was much less so. If we calculate means and variances--variance is a measure of dispersion around the mean--the middle third of years was both drier and more predictable than the others. I arrived just in time to exploit the return of the Gold Rush era climatic unpredictability, and I was in Seventh Heaven.
And here is the seasonal snowfall data from Donner Summit, where the pattern is less clear
Those factors are going to vary with altitude and climate
A species occurring here in the High North Coast Range of Colusa County has to deal with snowmelt timing, a factor that will not impinge directly on the same species in the foothills below. When we have multiple years of data for the same locations, we can work out detailed analyses of the factors controlling seasonability.
At low elevations, we find ample evidence of advancing first-flight dates (FFDs)
We have a set of 20 indicator species that have been tracked at all our low-elevation sites throughout the study (we had 23, but 3 have gone regionally extinct, like the Large Marble (Euchloe ausonides).
These two species have been the most responsive to climatic warning in our study: the Red Admiral (Vanessa stalanta) and the Field Skipper (Atalopedes campestris)
Both have fascinating back stories. The Red Admiral, which hibernates as an adult, also occurs in the U.K., where it has ALSO been the most phenologically responsive species to climatic warning. And the Field Skipper, which in the 1920s was confined to Southern California, expanded northward, reaching near the Oregon border by 1980 and subsequently expanding its breeding and overwintering range to Washington State and western Nevada, where it had previously been a rare stray. Its spread is statistically closely matched with climatic trends.
Cabbage White Butterfly
The Cabbage White Butterfly (Pieris rapae) has a special place in our study--because we enlist the general public in trying to document its FFD.
We offer a pitcher of beer for the first Pieris rapae collected in Yolo, Solano of Sacramento counties each year. The idea is to get as many people as possible out looking for it. If I begin losing frequently, this says I'm not looking hard enough. Public participation keeps me honest. I've lost 5 times in 45 years. Actually 7, but two finds were ruled inadmissible because the butterflies were caught indoors--both in kitchens. Sometimes a mature caterpillar will be brought in on a head of cabbage, escape undetected, and pupate somewhere. Then, given the higher indoor temperature, it hatches into an adult before any are flying outside. The rules originally didn't specify that the beast had to be caught outdoors. They do now. As sole judge, I simply declared those two indoor bugs ineligible!
So, what have we found?
Near sea level, of the 20 surviving indicator species, 9 are emerging significantly earlier in the 2010s than in the 1970s and 2 are significantly later--but those 2 are in the process of going regionally extinct and their apparent lateness appears to result from the low probability of encountering such rare species. The remainder are not statistically significant, but most are earlier. The average significantly earlier species is emerging 2/3 of a day earlier/year, on average, or a week earlier/decade!
One of the disappearing ones is the Field Crescent (Phyciodes campestris).
One consequence of climate change may be to disrupt butterfly-plant synchrony
Especially for specialist species, if the phenology of the insect responds to climate change differently from that of plants that are essential to its life cycle--be they larval host plants or adult nectar sources--that species is going to be in big trouble!
Many multiple-brooded lowland species change host plant with each generation, making this potentially a complex "many-body problem."
Butterfly seasonality is critically dependent on the amount of snow pack and the timing of snow melt. As a previous graphic showed, there as NOT been a clear trend in total seasonal snowfall at Donner Summit since records have been kept. This is a picture at 7000 feet on June 24 last year. During the preceding drought, there was no snow at all on the ground here by June 24 and many things were happening--flowers blooming, butterflies flying. Analysis of data from our mountain sites thus requires use of variables beyond those taken into account at lower elevations, and is very effort-intensive.
This is the ridgetop between Castle and Basin Peaks at 9000 feet, west slope at left. Note how the snow persists much later on the east slope. This is partly due to the SW wind redistributing snow from the west side to the east, generating massive "cornices" which are slow to melt and would form the nuclei of growing glaciers if favorable conditions persisted several years. Butterfly species that occur on both slopes may emerge weeks later on the east side than on the west slope at the same elevation, producing a prolonged flight season.
These two Coopers occur at 7000 feet, but have no host plant at 9000 feet. We see adults at 9000 feet with increasing frequency, but they cannot breed.
In unflooded places, wet ground and a saturated "boundary layer" of air above the ground are favorable for bacterial and fungal pathogens to proliferate, and overwinter mortality is heavy.
But lack of snow portends a poor butterfly season
But here we see as whatever moisture produced by melting snow is long gone. Butterfly seasons after a poor snow pack tend to end early as the vegetation dries up!
In the high country, heavy snow INCREASES butterfly numbers (and diversity to some extent), and lack of snow INCREASES them.
Because the recent drought went on for over 4 years, the cumulative damage to montane butterfly faunas was far too great to be alleviated by good overwinter survival under one year's heavy snow pack. There were too few animals under the snow at the outset.
Our butterfly faunas have experienced a great deal of climatic variation on multiple time scales. We know from fossil pollen and other indicators that California climates have been exceedingly variable since the end of the Pleistocene ice ages, some 15,000 years ago. Remember our discussion of noise vs. signal? In the short term, a 5-year drought is a critical event. IN the longer term, we know there have been 400-year droughts. We know that the vegetation that exists today--apart from human impacts!--can be seen as a freeze-frame taken from a very long movie. The butterflies we have today are the species that have been able to persist, either by adapting to climate change or by moving around to track favorable conditions--or both. Our studies document their coping mechanisms on a short (45-year) time scale--but no one has ever done that before. They give us data that will help us predict biotic responses to FUTURE climate change--which is essential for their well-being AND OURS.

The walking sticks, or stick insects, belong to the order Phasmatodea. The Phasmids, a word derived from "phantom" in ancient Greek, refers to their ghost-like ability to camouflage themselves as leaves or twigs.
They're found on all continents except Antarctica.
At the recent Bohart Museum open house, hands reigned supreme in the form of "guiding hands" and "hand-over-hand" as visitors cradled the 'sticks.
Definitely a "hands-on" activity!
The Bohart Museum, home of a global collection of eight million insect specimens, is located in Room 1124 of the Academic Surge Building, 455 Crocker Lane, UC Davis campus. It houses the seventh largest insect collection in North America. It is also the home of the California Insect Survey, a storehouse of insect biodiversity. Noted entomologist Richard M. Bohart (1913-2007) founded the museum in 1946.
The Bohart Museum also maintains an insect-themed gift shop, stocked with t-shirts, hoodies, jewelry, books, posters and insect-collecting equipment.
In fact, the gift shop includes a t-shirt, "Know Your Sticks." It includes a stick person, a real stick or twig, a Vietnamese walking stick and an Australian spiny stick. Entomologist Fran Keller, then a doctoral student at UC Davis and now a professor at Folsom Lake College, came up with the idea, and Ivana Li, then an entomology student doubling as president of the Entomology Club--and now biology lab manager at UC Davis--drew the illustrations.
New hours! The Bohart Museum is open to walk-in-visitors on Tuesdays through Thursdays, from 9 a.m. to noon, and from 1 to 4:30 p.m.
The museum will be operational on Mondays and Fridays as well, but the focus will solely be on research those days. Director of the museum is Professor Jason Bond the Evert and Marion Schlinger Endowed Chair, UC Davis Department of Entomology and Nematology, and associate dean, UC Davis College of Agricultural and Environmental Sciences.
For the campuswide UC Davis Picnic Day on Saturday, April 20, the Bohart Museum is planning a pop-up tent at Briggs Hall; the Academic Surge building will be closed. For more information on the Bohart Museum, access the website or email bmuseum@ucdavis.edu.

The bee buzzed cautiously amid the pink and white flowers, near anglers, kayakers, picnickers, bench occupiers, and walkers.
"Bumble bee!" I whispered, raising the camera. "Bombus vosnesenskii!"
Nobody seemed to notice. "Just a bee," they probably thought. "Just a bee."
The site is named for Matthew Turner (1825-1909), a sea captain, shipbuilder and designer who built ships at the site.
Wikipedia tells us: "He constructed 228 vessels, of which 154 were built in the Matthew Turner shipyard in Benicia. He built more sailing vessels than any other single shipbuilder in America, and can be considered 'the 'grandaddy' of big time wooden shipbuilding on the Pacific Coast...Turner also built some of the fastest racing yachts in the world, proven out during the famous races sponsored by the San Francisco Yacht Club, of which Turner was a charter member."
A historical marker at the Benicia site reads: "In 1882, Matthew Turner of San Francisco relocated his shipyard to Benicia. Turner, the most prodigious shipbuilder in North America, constructed 228 vessels, 169 of which were launched here. In 1913, the shipyard was purchased by James Robertson, who operated it until 1918. The yard's ways, and the whaler "Stamboul," used as a shipyard work platform, are visible at low tide."
The State Department of Parks and Recreation, in cooperation with the City of Benicia, designated the site as California Registered Historical Landmark No. 973 on June 18, 1987.
Turner would have been proud of the "namesake" park. And maybe, just maybe, while he was building ships, he may have noticed a bumble bee...or two...or three....

When UC Davis distinguished professor emeritus and noted integrated pest management specialist Frank Zalom of the Department of Entomology and Nematology received a Lifetime IPM Achievement Award from the California Department of Pesticide Regulation (CDPR), his colleagues and former graduate students rushed to congratulate him.
Zalom officially retired in 2018 but continues his IPM research and outreach efforts as a recall professor in the Department of Entomology and Nematology. His 45-year career includes director of the UC Statewide IPM Program for 16 years.
The best accolade we've heard came from UC Davis doctoral alumnus Mohammad Amir Aghaee: "Frank Zalom is the Michael Jordan of IPM."
Aghaee posted that on the "Insects & Entomology" section of LinkedIn.
Aghaee, now entomology program leader with California Polytechnic State University (Cal Poly), San Luis Obispo, was a top-notch graduate student at UC Davis. He won the 2015 John Henry Comstock Award, the highest graduate student award given by the Pacific Branch, Entomological Society of America and numerous other honors. (See news story) At the time he received the award, Aghaee was a fifth year Ph.D. candidate working on rice water weevil management in California rice.
Carlos Bográn: "No one more deserving of this recognition! Thank you for sharing, this is very special to many of us that have learned from him and his example of professionalism and grace."
David Bellamy: "Congratulations, Frank. Clearly well deserved..."
Carlos Vargas: You, sir, are a great wealth of knowledge..."
Numerous entomologists and organizations turned to X (formerly Twitter) to congratulate Zalom. UC Davis distinguished professor Walter Leal of the Department of Molecular and Cellular Biology, and former chair of the Department of Entomology, posted a newspaper clipping of Zalom talking to his former student Hannah Burrack, now professor and chair of the Department of Entomology, Michigan State University. The headline: "Separating the Good Bugs from the Bad."
Comments on Facebook included:
Walter Bentley (UC IPM entomologist, emeritus): "Congratulations, Frank. This is a well-deserved honor."
The UC Davis Department of Entomology and Nematology website chronicled Zalom's achievements in a comprehensive news story. CDPR praised Zalom for “advancing IPM practices in California specialty crops as a preeminent researcher, practitioner and champion of sustainable pest management.”
"Dr. Zalom's work has contributed greatly to advancing safe, effective, and sustainable IPM practices in specialty crops such as almonds, strawberries, tomatoes, and olives,” a CDPR spokesman said. “Through hundreds of presentations and publications, Dr. Zalom has contributed to broad adoption of IPM practices for numerous agricultural pests, resulting in less insecticide use and reduced run-off impacts and high-risk pesticide exposures.”
The news story went on to note that Zalom's career led to his presidency of the 7000-member Entomological Society of America (ESA) in 2014, and ESA's highest honor, Honorary Member, in 2021. His peers also elected him Fellow of the ESA, American Association for the Advancement of Science, Royal Entomological Society (London), and the California Academy of Sciences.
Among Zalom's many other accomplishments:
- He served as editor-in-chief of ESA's Journal of Economic Entomology from 2018-2022.
- The American Entomologist featured him in a 2023 "legends of entomology" piece titled Blue Collar California.
- He has authored or co-authored 376 journal articles and book chapters. Google Scholar attributes more than 11,000 citations to his papers, and assigns a h-index score of 50 and an i-index score of 207 to these works. (The i-index reflects the number of his papers that have been cited at least 10 times in other research papers.)
- He has delivered more 900 presentations at various clientele meetings in California since 1980.
- He has published well over 400 outreach articles on practical IPM during his 43-year UC career.
- He served as editor-in-chief of ESA's Journal of Economic Entomology from 2018-2022. This 115-year-old publication is the "most cited" journal in entomology, and well over half of the papers originate from outside of the U.S.
- He has participated in various international leadership projects involving IPM. (See more)
Today we're sharing three links to the CDPR's Feb. 29th ceremony, honoring five recipients:
