You'll see insects you've never seen before--and learn a little about them.
The cover image of the larva of the elm zigzag sawfly, Aproceros leucopoda (order Hymenoptera, family Argidae), native to Asia, is especially spectacular. It's the work of Christian Brockes of Germany.
"The elm zigzag sawfly is an east-Asian pest of elms (Ulmus spp), invasive in Europe since about 10 years ago and now also established in some North American regions," the ESA text relates. "The common name was inspired by the very distinctive patterns that their larvae leave on elm trees, while feeding. In large numbers, this species can critically damage elm populations. Often dozens of the tiny larvae--each only a few millimeters long--can be found on a single leaf, which they can skeletonize in a short period of time."
Scientists first detected this pest in the United States (Virginia) in 2021. Since 2022, it's been confirmed in four other states: Pennsylvania, North Carolina, Maryland and New York, according to research published in July 2023 in the Journal of Integrated Pest Management. The elm zigzag sawfly feeds exclusively on elms (Ulmus spp). It draws its name from the zizag-shaped pattern on the leaves as the larvae feed.
ESA prides itself on publishing world-class photography. Among the eight judges this year: Alex Wild, curator of entomology at the University of Texas and a doctoral alumnus from UC Davis. Wild studied with ant specialist Phil Ward, professor of entomology, UC Davis Department of Entomology and Nematology.
ESA issues a call for photos every January, and publishes the calendar every November. Of added interest, unselected images may appear on social media in the ESA's weekly "Arthropod Photo of the Week." Follow "Arthropod Photo of the Week" via the #arthropodPOTW hashtag on Twitter, Facebook, Instagram, and Mastodon.
We remember that an image of a hoverfly by UC Davis alumnus Alexander Nguyen appeared in the 2018 World of Insects Calendar. (See UC Davis of Entomology and Nematology website.) Judges chose his photo as one of the 12 winning images from a field of 560 entries submitted by 133 photographers from multiple continents. Nguyen captured the image at the UC Davis Stebbens Cold Canyon Reserve in April 2017, using his Canon 7D camera and a MPE 65-mm lens. Senior insect biosystematist Martin Hauser of the California Department of Food and Agriculture identified the hover fly as a male Platycheirus trichopus (Thomson, 1869).
What images are in the 2024 calendar? You'll see an ant tending treehopper nymphs, a chalcid wasp on Hemipteran eggs, stingless bees, a sunburst diving beetle, a Baltimore checkerspot butterfly, a Corsican owlfly, an ant-mimicking crab spider, a giant silk moth, an ambush bug preying on a bumble bee, a chestnut weevil, a poplar sphinx moth and an East Asian red damselfly. In addition, images that won honorable mentions share space on the calendar.

This is the story of how two native bees from Vacaville, Calif., traveled 1872 miles to Oklahoma City.
Not really.
But a photo I took in Vacaville of two Melissodes agilis bees zipping over a Mexican sunflower, Tithonia rotundifola, happened to win a top prize at the 63rd North Central Insect Photographic Salon, co-sponsored by the North Central Branch of the Entomological Society of America (ESA) and the Photographic Society of America.
Judges scored it "Best Image by an ESA Member." All 7000 ESA members are invited to contribute, as are non-members. I wasn't planning to enter--this was my first time--but Insect Salon coordinator/ESA member Tom Myers posted a note on Facebook seeking images to be showcased at the 2023 Joint North Central and Southwestern Branch meeting in Oklahoma City. The theme: "Branch Cross-Pollination: Seeking Hybrid Vigor in Science through Communication, Collaboration, and Societal Impact."
The North Central Branch covers Colorado, Illinois, Indiana, Iowa, Kansas, Kentucky, Michigan, Minnesota, Missouri, Nebraska, North Dakota, Ohio, South Dakota, Wisconsin, plus parts of Canada (Manitoba, Nunavut, Ontario) while the Southwestern Branch encompasses New Mexico, Oklahoma and Texas, and all of Mexico, except Baja California, Baja California Sur, Sinaloa and Sonora.
To be accepted for display, a photo must score 85 points or more. The image of the male and female bees, which I titled "Catch Me If You Can," scored 94 points, and two other Garvey images, one of a golden dung fly (Scathophaga stercoraria), "Checking You Out," and the other titled "I Do," of two Gulf Fritillaries (Agraulis vanillae), tallied 92 and 89 points, respectively. "Checking You Out" earlier won "Best Image by an ESA Member" in the 64th annual International Insect Salon competition.
The M. agilis species are fun to photograph, but set your shutter speed high. These bees are the Usain Bolts of the bee world. Catch me if you can!
I captured the image of "Catch Me If You Can" with a Nikon D500, mounted with a 200mm lens. Settings: shutter speed set at 1/8000 of second, f-stop 5, and ISO 800.
For "Checking You Out:" Nikon D500 with a 105mm lens, 1/320 of second, f-stop 9, and ISO 800.
For "I Do": Nikon D500 with a 70-180 lens (110 focal length), 1/640 of a second, f-stop at 10, and ISO of 800.
All were taken in our family's pollinator garden. (No tripod, no flash.) The added benefit of planting a pollinator garden includes capturing images of the residents and visitors.
Me? I'm just a guest in their habitat. I don't poke 'em, prod 'em or pin 'em. I just photograph them. When. They. Let. Me.

She--and any others near them--will smile every time!
Fact is, Rob Page is our favorite honey bee geneticist, and he was just named the recipient of the 2023 C. W. Woodworth Award, the highest honor accorded by the Pacific Branch, Entomological Society of America (PBESA).
It's an honor well deserved. And a honey of an award.
“Dr. Page is a pioneering researcher in the field of evolutionary genetics and social behavior of honey bees, and a highly respected and quoted author, teacher and former administrator,” wrote nominator Steve Nadler, professor and chair of the UC Davis Department of Entomology and Nematology.
Page is the 12th UC Davis recipient of the award, first presented in 1969. His mentor, and later colleague, Harry H. Laidlaw Jr. (for whom the UC Davis bee biology research facility is named), won the award in 1981.
The PBESA awards ceremony will take place at its meeting, April 2-5, in Seattle. The organization encompasses 11 Western states, and parts of Canada, Mexico and U.S. territories.
“One of Dr. Page's most salient contributions to science was to construct the first genomic map of the honey bee, which sparked a variety of pioneering contributions not only to insect biology but to genetics at large,” Nadler related. “It was the first genetic map of any social insect. He was the first to demonstrate that a significant amount of observed behavioral variation among honey bee workers is due to genotypic variation. In the 1990s, he and his students and colleagues isolated, characterized and validated the complementary sex determination gene of the honey bee; considered the most important paper yet published about the genetics of Hymenoptera. The journal Cell featured their work on its cover. In subsequent studies, he and his team published further research into the regulation of honey bee foraging, defensive and alarm behavior.”
Page's career at ASU led to a series of top-level administrative roles: founding director, School of Life Sciences (2004-2010), vice provost and dean, College of Liberal Arts and Sciences (2011-2013) and university provost, 2014-2015.
Nadler praised Page's strategic vision, his leadership and his contributions to science. He built two modern apicultural labs (in Ohio and Arizona), major legacies that are centers of honey bee research and training. The Social Insect Research Group (SIRG) at ASU is regarded as “the best in the world,” according to the late E. O. Wilson. ASU Professor Bert Hoelldobler, in an ASU news release, declared Dr. Page as "the leading honey bee geneticist in the world. A number of now well-known scientists in the U.S. and Europe learned the ropes of sociogenetics in Rob's laboratory.”
While at UC Davis, Page worked closely with Harry H. Laidlaw Jr., the father of honey bee genetics, and together they published many significant research papers and the landmark book, “Queen Rearing and Bee Breeding” (Wicwas Press, 1998). It is considered the most important resource book for honey bee genetics, breeding, and queen rearing. Page is now in the process of updating it.
For 24 years, from 1989 to 2015, Page maintained a honey bee-breeding program, managed by bee breeder-geneticist Kim Fondrk. Their contributions include discovering a link between social behavior and maternal traits in bees. Their work was featured in a cover story in the journal Nature. In all, Nature featured his work on four covers from work mostly done at UC Davis.
A 2012 Fellow of the Entomological Society of America, Page has held national and international offices. He served as secretary, chair-elect, chair, subsection cb (apiculture and social insects) of ESA from 1986-1989; president of the North American Section, International Union for the Study of Social Insects, 1991; and a Council member, International Bee Research Association, 1995-2000.
Among his many honors:
- Fellow of the American Association for the Advancement of Science
- Awardee of the Alexander von Humboldt Senior Scientist Award (the Humboldt Prize - the highest honor given by the German government to foreign scientists)
- Foreign Member of the Brazilian Academy of Sciences
- Fellow of the American Academy of Arts and Sciences
- Elected to the Leopoldina - the German National Academy of Sciences (the longest continuing academy in the world)
- Fellow of the Wissenschaftskolleg zu Berlin
- Fellow of the Entomological Society of America
- Awardee of the Carl Friedrich von Siemens Fellowship
- Fellow of the California Academy of Sciences
- Fellow, Carl Friedrich von Siemens Foundation, Munich, Germany, September 2017-August
- Thomas and Nina Leigh Distinguished Alumni Award from UC Davis Department of Entomology and Nematology
- James Creasman Award of Excellence (ASU Alumni Association)
- UC Davis Distinguished Emeritus Professor, one awarded annually
- Distinguished Emeritus Award, College of Agricultural and Environmental Sciences, one awarded annually
In his letter of support, colleague and research collaborator James R. Carey, distinguished professor of entomology at UC Davis, described Page as "one of the most gifted scientists, administrators, and teachers I have had the privilege to know in my 42 years in academia.”
Bee breeder-geneticist Susan Cobey of Washington State University, former manager of the Laidlaw facility, emphasized Page's importance to the bee breeding and beekeeping industry. Cobey, who has based her career on the Page-Laidlaw Closed Population Breeding, wrote that: “The beauty of this system is that it is practical and addresses the unique challenges of honey bee stock improvement. Queens mate in flight with numerous drones and selection is based upon complex behaviors at the colony level, influenced by the environmental. Hence, traditional animal breeding models do not apply well to honey bees.”
Nadler also noted that “Dr. Page was involved in genome mappings of bumble bees, parasitic wasps and two species of ants. His most recent work focuses on the genetic bases of individuality in honey bees; demonstrating genetic links between pollen and nectar collection, tactile and olfactory learning characteristics, and neuroendocrine function. This work provides the most detailed understanding to date of the molecular and genetic bases to task variation in a social insect colony.”
Nadler added: "Not surprisingly, Dr. Page humbly considers his most far-reaching and important accomplishment, the success of his mentees, including at least 25 graduate students and postdocs who are now faculty members at leading research institutions around the world."
Charles William Woodworth (1865-1940), is considered the founder of both the UC Berkeley and UC Davis departments of entomology. William Harry Lange Jr., (1912-2004) was the first UC Davis recipient of the Woodworth award (1978). Other recipients: Harry Laidlaw Jr., (1907-2003), 1981; Robert Washino, 1987; Thomas Leigh (1923-1993), 1991; Harry Kaya, 1998; Charles Summers, (1941-2021), 2009; Walter Leal, 2010; Frank Zalom, 2011; James R. Carey, 2014; Thomas Scott, 2015; and Lynn Kimsey, 2020.
Joining Rob Page in the 2023 PBESA winners' circle from UC Davis: community ecologist Louie Yang, professor, UC Davis Department of Entomology and Nematology, recipient of the Distinction in Student Mentoring Award; and UC Davis student Gary Ge, of the UC Davis Research Scholars Program in Insect Biology, who won the second annual Dr. Stephen Garczynski Undergraduate Research Scholarship.

Who takes images of flies? Raise your hand! No, not the hand with the flyswatter.
Well, almost anything is fair game for my camera.
That includes golden dung flies.
I am humbled to learn that my image of a golden dung fly won the Entomological Society of America (ESA) medal for "Best Image by an ESA Member" in the 64th annual International Insect Salon competition.
ESA showcased the winning images on Sunday, Nov. 13 at its joint meeting of the Entomological Society of Canada and the Entomological Society of British Columbia, which opened Nov. 13 and continues through Nov. 16 in Vancouver, British Columbia.
I captured the image of the fly, Scathophaga stercoraria, perched on a lavender stem in our family's pollinator garden in Vacaville and titled it “Checking You Out.” Scathophaga play an important role in the natural decomposition of dung. UC Davis distinguished professor Lynn Kimsey, director of the Bohart Museum of Entomology, identified the fly.
The Peoria Camera Club, Illinois, sponsors the Insect Salon in conjunction with ESA and the Photographic Society of America. Coordinator Joe Virbickis of the Peoria Camera Club said the images are restricted to insects, spiders, and related arthropods (such as barnacles, crabs, lobsters, shrimp, centipedes, and millipedes.) Each photographer may submit up to four entries. "The range for acceptances is 33-35 percent of eligible images," he said.
This year's competition drew 254 entries. Judges gave acceptances to photographers from 17 countries: Austria, Belgium, Canada, China, England, Germany, Hong Kong, India, Indonesia, Kazakhstan, Malaysia, New Zealand, Scotland, Singapore, Taiwan, United Kingdom, and United States. (See acceptances and awards at https://insectsalon.peoriacameraclub.com/results/2022/Html/sect_1.htm)
Two other images that I submitted also gained acceptances. One was of a crab spider nailing a katydid (Did or Didn't I?), and the other of a pollen-covered honey bee (Eureka! I Found It!).
Best of Show. Best of show medal went to Kenneth Gillies of West Lothian, Scotland, United Kingdom, for his “Peppermint Shrimps Inside a Sponge.”
Gillies was joined by the five other top winners:
- Medal for Most Unusual Image: Weihua Ma of Guangzhou City, Guangdong Province, China, for “Pretending to be a Branch.”
- Medal for Best Storytelling Image: Dre Van Mensel of Tielen, Antwerpen, Belgium, for “It's Mine.”
- Medal for Best Image by a ESA member: Kathy Keatley Garvey of UC Davis/Vacaville, Calif., for “Checking You Out.” (as earlier mentioned)
- Medal for Best Image by a non-ESA member, Tim Sanders of Bideford, Devon, England, for “At Work.”
- Medal for Best Peoria Camera Club member: Ladean Spring of Creve Coeur, lll., for “Hummingbird Moth.”
ESA member and noted insect photographer Tom Myers of Lexington, Ky., displayed the Insect Salon images at the ESA meeting. Virbickis assisted in preparing it. Myers is a frequent recipient of Insect Salon awards. His acceptances this year: "European Hornet Vespa Crabro" (honorable mention); "Chalcid Wasp 1"; and "Brood X Cicada Magicicada Sp."

The project? Fourteen articles in The Journal of Economic Entomology's Special Collection: Research Advances in Spotted-Wing Drosophila suzukii Management, published in the August 2022 edition.
The insect? It's native to Asia and primarily targets soft-skinned fruits in the berry industry, such as raspberries, blackberries, blueberries, strawberries, and cherries. The tiny insect, about 1/12 to 1/8 inch long, invaded the continental United States in 2008.
The authors? They're from eight countries: United States, Austria, Brazil, Canada, Italy, Spain, Sweden, and the United Kingdom and represent perspectives from universities, federal and state laboratories, growers, and pest product companies.
Thirteen UC Davis scientists or former affiliates are among the authors who contributed.
“All of the papers were by invitation of the co-editors of the special collection—Jana Lee, Cesar Rodrigue-Saona, and me,” said journal editor-in-chief Frank Zalom, a UC Davis distinguished professor emeritus and recall professor in the Department of Entomology and Nematology. Zalom's research includes the insect, Drosophila suzukii.
Lee, formerly with the UC Davis laboratory of the late chemical ecologist Steve Seybold, is a research entomologist with the Horticultural Crops Research Unit, U. S. Department of Agriculture, Agricultural Research Service, Corvallis. Rodriguez-Saona, who received his doctorate from UC Riverside, is an Extension entomologist with the Department of Entomology, Rutgers University, the State University of New Jersey.
One paper, Spatio-temporal Variation of Spinosad Susceptibility in Drosophila suzukii (Diptera: Drosophilidae), a Three-year Study in California's Monterey Bay Region, is from the Zalom lab and includes co-author, molecular geneticist and physiologist Joanna Chiu, professor and vice chair of the Department of Entomology and Nematology.
Since 2008, "D. suzukii has become a key economical pest of raspberries, blackberries, blueberries, strawberries, and cherries in the United States and worldwide," the editors wrote in their introductory remarks. "Not surprisingly, the number of publications has proliferated from 29 publications as of 2010 to 978 additional publications between 2011 and 2021 from a Web of Science search for ‘Drosophila suzukii.' While many publications are available, this special collection will highlight advances in D. suzukii pest management since its U.S. invasion. We solicited papers by open call and received 66 abstracts, and selected 14 papers covering: 1) review, 2) monitoring and risk, 3) behavioral control, 4) biological control, 5) cultural control, and 6) chemical control."
The editors pointed out that “Given that 14 years of research has accumulated since the continental U.S. invasion, it was fitting to include two reviews that provide a different scope than was covered in prior reviews on D. suzukii biological control (Lee et al. 2019, Wang et al. 2020), trapping (Burrack et al. 2020), cultural control (Schöneberg et al. 2021), and chemical ecology (Cloonan et al. 2018). This special collection is anchored by Tait et al. (2021), a review of the most promising methods as part of an Integrated Pest Management (IPM) strategy against D. suzukii across the world since 2008. The effectiveness, impact, sustainability, and present stage of development and implementation are discussed for each of the considered techniques, and insights for continued development are presented.”
The researchers related that the pest is a significant threat to California's berry production industry, which the California Department of Food and Agriculture (CDFA) valued at more than $2.8 billion in 2019. Caneberries, in particular, "are a preferred host of D. suzukii, and California accounts for 89.4 percent of all production in the United States, with the Monterey Bay region producing about half of the state's raspberries and blackberries (CDFA 2020). This pest has now spread to all major berry and cherry growing areas of the United States."
The collection is meant to serve "as a key reference point for entomologists across many institutions (e.g., academia, government, and industry) on important advances in D. suzukii pest management," according to the Entomological Society of America. "The articles in this collection will also provide scientists information on potential research gaps that will help guide future research directions on this important pest. The goal is to preserve and catalog articles on various aspects of D. suzukii pest management, i.e., monitoring, cultural control, chemical control, behavioral control, and biological control, that will be shared among entomologists."
