The predators and their prey were all in costumes, of course:
- The queen bee: UC Davis distinguished professor Lynn Kimsey, director of the Bohart Museum
- The praying mantis: Tabatha Yang, education and outreach coordinator of the Bohart Museum
- The green darner dragonfly: Christofer Brothers, a UC Davis doctoral candidate researching dragonflies
- The monarch: Barbara Heinsch, a Bohart Museum volunteer, who arrived with her entomologist-husband, Mike Pitcairn, retired senior environmental scientist, supervisor, California Department of Food and Agriculture (CDFA). He wore his CDFA lab coat and swung an insect net.
And the guy in the ghillie suit serving beverages (that would be forensic entomologist Robert "Bob" Kimsey of the UC Davis Department of Entomology and Nematology) is keenly interested in flies, but he didn't net the fly.
UC Davis entomology alumna Ivana Li, a biology lab manager at UC Davis, catered the event and arrived with her dog, Juniper, dressed as a taco. Lynn Kimsey cut a carrot cake, decorated with tiny carrots and large googly eyes.
Some attendees, including Joanna Chiu, professor and chair of the Department of Entomology and Nematology; UC Davis doctoral alumna Fran Keller, professor at Folsom Lake College; Bohart Museum associate Greg Karofelas; UC Davis doctoral alumnus Dick Meyer (who studied with the late Richard Bohart); and entomology student Kaitai Liu, arrived as themselves, sans Halloween costumes.
The Bohart Museum, located in Room 1124 of the Academic Surge Building, 455 Crocker Lane, houses a global collection of eight million insect specimens, plus a live insect petting zoo and a gift shop. Founded in 1946 by the late UC Davis professor Richard Bohart, it has been directed by Kimsey, his former doctoral student, since 1990.

Next Open House on Monarchs. The Bohart's next open open house, set from 1 to 4 p.m., Saturday, Nov. 4, is on monarchs.
The event, free and family friendly, will be held in Room 1124 of the Academic Surge Building, Crocker Lane. This is an opportunity for attendees to ask questions about monarchs (Danaus plexippus) and native vs. non-native milkweed, among other topics.
The scientists will include:
- UC Davis distinguished professor emeritus Art Shapiroof the Department of Evolution and Ecology, who has studied butterfly populations in central California since 1972 and maintains a research website, Art's Butterfly World.
- UC Davis emeritus professor Hugh Dingle, a worldwide authority on animal migration, including monarchs. He is the author of Migration: The Biology of Life on the Move (Oxford University Press), a sequel to the first edition published in 1996. See news story on the UC Davis Entomology and Nematology website.
- UC Davis professor Louie Yang, who does research on monarchs. Due to parental duties, he may be able to attend only the last part of the open house. See news story about his work.
- UC Davis professor Elizabeth Crone of the Department of Evolution and Ecology, formerly of Tufts University, who researches monarchs. See news story about the declining monarch population on the UC Davis Entomology and Nematology website.
- UC Davis postdoctoral fellow Aramee Diethelm of the Elizabeth Crone lab. She holds a doctorate from the University of Nevada, Reno. Both her Ph.D. and postdoctoral work are on monarch butterflies. As a doctoral student, she investigated the phytochemical landscape of milkweed (Asclepias) species across northern Nevada and the effects of this variation on western monarch (Danaus plexippus) butterfly performance. See her research posted on Google Scholar, and her blog on "Drought Influences Monarch Host Plant Selection."
Shapiro points out that the monarch "is NOT a focal species in my research and I am NOT a monarch expert. On the other hand, I have a unique breeding-season census data set starting in 1999. The only other census data are for the overwintering roosts on the coast. It has become apparent that the two data sets do not always agree." Shapiro said he'd talk briefly about this at the open house.

Background. The Bohart Museum, located in Room 1124 of the Academic Surge Building, 455 Crocker Lane, houses a global collection of eight million insect specimens, plus a live insect petting zoo and a gift shop. Founded in 1946 by the late UC Davis professor Richard Bohart, it has been directed by Kimsey, his former doctoral student, since 1990.
A recognized authority on insect biodiversity, systematics and biogeography of parasitic wasps, urban entomology, civil forensic entomology, and arthropod-related industrial hygiene, Kimsey is a 34-year member of the UC Davis entomology faculty and a UC Davis alumna, holding bachelor and doctoral degrees in entomology.
When former department chair Richard Bohart (for whom the museum is named), founded the museum in 1946, it was a “hole in the wall” in Briggs Hall that included only 400 insect specimens. Under Kimsey's tenure, it has grown to a global collection of eight million insect specimens and is the seventh largest insect collection in North America.
The Bohart draws an average of 15,000 visitors a year, adds an average of 30,000 new specimens annually, and loans an average 7000 specimens yearly to scientists worldwide. It supports campus classes with specimens, live insects and exhibits in keeping with its mission: “Understanding, documenting and communicating terrestrial arthropod diversity.”

If you have a passionflower vine (Passiflora), you probably have cats.
No, not the four-legged ones that meow, chase mice or cavort with catnip.
These 'cats or caterpillars are part of the life cycle of the Gulf Fritillary butterflies (Agraulis vanillae) and Passiflora is their host plant.
Watch for the chewed leaves, the frass (poo) and the chrysalids.
Expect a cat-tastrophe when predators like the California scrub jays, European paper wasps, and praying mantids appear and the 'cats disappear.
The circle of life...

It's early morning and the spider is hungry.
It snares a honey bee foraging for pollen and nectar in a patch of Mexican sunflowers (Tithonia rotundifola) in a Vacaville pollinator garden.
The spider slides down the sticky web, kills its prey with a venomous bite, and begins to eat.
The spider is not alone. It soon has unexpected dining partners: tiny freeloader flies (family Milichiidae) who did no work but insist on their share of the free food.
Indeed, orbweavers are artists. Wrote Emily Dickinson (1830-1886) in her poem, "The Spider as an Artist":
The spider as an artist
Has never been employed
Though his surpassing merit
Is freely certified.
Today was a good day for an unemployed artist, freely certified, too--and a good day for the freeloaders, certified hungry.
Emily Dickinson? She wrote many poems with references to such arthropods as bees, spiders, butterflies, flies and gnats,
Emily Dickinson's Arthropods
"By my count, 180 of Dickinson's 1,775 poems refer to one or more arthropods," wrote U.S. Army medical entomologist (retired) Louis C. Rutledge in The American Entomologist, summer of 2003.

Bee scientist James Nieh, a UC San Diego professor in the Section of Ecology, Behavior and Evolution, Division of Biological Sciences, will present the first fall quarter seminar hosted by UC Davis Department of Entomology and Nematology.
Nieh will speak on "Animal Information Warfare: How Sophisticated Communications May Arise from the Race to Find an Advantage in a Deadly Game Between Honey Bees and Their Predators" at 4:10 p.m., Wednesday, Sept. 25 in 122 Briggs Hall. Brian Johnson, associate professor of entomology, is the host.
"In addition to the classical arm race that has evolved between predators and prey, information races also occur, which can lead to the evolution of sophisticated animal communication," Nieh says in his abstract. "Such information can shape the food web and contribute to the evolution of remarkable communication strategies, including eavesdropping, referential signaling and communication within and between species, including between predators and prey."
"I focus on the world of information exchange (acoustic, olfactory and visual) that has co-evolved between Asian honey bees (Apis cerana, A. florea, and A. dorsata) and their predators, the Asian hornets (Vespa velutina and V. mandarinia)," Nieh says. "I will explore how and why such information races occur through the remarkable examples provided by these high social insects."
He presented a TED talk on "Bees and Us: an Ancient and Future Symbiosis" in July 2019.
A native of Taiwan, Nieh grew up in Southern California and received his bachelor's degree in organismic and evolutionary biology in 1991 from Harvard University, Cambridge, and his doctorate in neurobiology and behavior from Cornell University, Ithaca, N.Y., in 1997. He subsequently received an NSF-NATO postdoctoral fellowship to study at the University of Würzburg in German. A Harvard junior fellowship followed.
Nieh joined the faculty of the Section of Ecology, Behavior and Evolution in 1997 as an assistant professor, advancing to associate professor in 2007 and professor in 2009. He served as vice chair of the section from 2009 to 2014, and as chair from 2014 to 2017.
His latest co-authored research, published in the journal Chemosphere in 2019, is titled Combined Nutritional Stress and a New Systemic Pesticide (flupyradifurone, Sivanto®) Reduce Bee Survival, Food Consumption, Flight Success, and Thermoregulation.
Assistant professor Rachel Vannette is coordinating the fall quarter seminars. (See list of seminars.)She may be reached at rlvannette@ucdavis.edu.
