Treat, please, says this jumping spider.
It's time to jump in to help the 13th annual UC Davis Biodiversity Museum Day crowdunding project.
It's a Super Science Day to be held Saturday, Feb. 10 on the UC Davis campus.
It's a free and family friendly event. You can visit such biological museums or collections as the Phaff Yeast Culture Collection, Bohart Museum of Entomology, Museum of Wildlife and Fish Biology, Arboretum and Public Garden, California Raptor Center, Earth and Planetary Sciences Paleontology Collections, Botanical Conservatory, Center for Plant Diversity, Nematode Collections, Marine Invertebrate Teaching Collection, and the Department of Anthropology Museum.
And you can talk to the scientists one-on-one.
The crowdfunding project ends at 11:59 p.m., Monday, Oct. 30. You can donate here. You can donate in memory of a loved one, or, for example, to honor your favorite scientist or favorite insect or spider.
"Donations will help us sustain this free science event, and enable our student interns to take science outreach to a whole new level," according to Biodiversity Museum Day chair Tabatha Yang, education and outreach coordinator for the Bohart Museum of Entomology." The goal of our event is to connect people from all walks of life to science and the biodiversity surrounding them."
Donation levels start at $5.

Then you'll want to attend the Bohart Museum of Entomology open house on Saturday, Nov. 4 from 1 to 4 p.m. in Room 1124 of the Academic Surge Building, 455 Crocker Lane. Scientists will be there to answer your questions.
The event is free and family friendly and a great opportunity to learn more about Danaus plexippus.
The scientists will include:
- UC Davis distinguished professor emeritus Art Shapiro of 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
Shapiro, a Lepidopterist, 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.
"The iconic black and orange monarch butterfly is known for its astonishing long-distance annual migration and reliance on milkweed as its obligate larval host plant," according to a post on the California Department of Fish and Wildlife (CDFW). "Though genetically similar, there are two subpopulations of monarchs in North America, with the eastern population overwintering in Mexico and breeding in the midwestern states, and the western population overwintering in coastal California and fanning out across the west from Arizona to Idaho. Outside the U.S., there are at least 74 known populations of resident, non-migratory monarchs that have established around the world in the past 200 years, all with origins in North America (Nial et al. 2019)."
"Both North American migratory populations have declined over the past twenty years due to a suite of interrelated factors including habitat loss in breeding and overwintering sites, habitat degradation, disease, pesticide exposure, and climate change," CDFW says. "Recently the western population has experienced dramatic swings, for a low of less than 2,000 in 2020-21 to over 200,000 in 2021-22 (Xerces Society Western Monarch Count). While it is unclear which of the many factors are driving these dynamics, insect population commonly fluctuate from year to year. The overall downward trend remains concerning, particularly if the threats are not ameliorated. Though more research is needed, a stable population for western monarchs is likely closer to the historic averages in the 1980's, which are estimated to have ranged between one to four million overwintering butterflies."
"n 2014, monarchs were petitioned to be listed under the federal Endangered Species Act. In December 2020, the U.S. Fish and Wildlife Service found that listing was warranted but precluded by other listing actions on its National Priority List. The monarch is currently slated to be listed in 2024."
The monarch population is in trouble. Says the Xerces Society for Invertebrate Conservation in a post on its website: "In the 1990s, hundreds of millions of monarchs made the epic flight each fall from the northern plains of the U.S. and Canada to sites in the oyamel fir forests in central Mexico, and more than a million monarchs overwintered in forested groves on the California coast. Now, researchers and community scientists estimate that only a fraction of the population remains—a decline of approximately 70% has been seen in central Mexico and a decline of >90% has been seen in California."

What, you don't? They scare you? And you scream?
Fear not.
Arachnologists will set the record straight. (Maybe not your scream, though!)
Just in time for Halloween, the next UC Davis Department of Entomology and Nematology seminar will be on spiders.
Arachnologist Rodrigo Monjaraz-Ruedas of San Diego State University's Department of Biology, will speak on "Ring Species, Ring Speciation or a Ring of Species? An Example with California Mygalomorph Spiders" at 4:10 p.m., Monday, Oct. 30 in Room 122 of Briggs Hall. It also will be on Zoom.

"Ring species can be defined as a chain of interbreeding populations which expands along two pathways around a geographic barrier, where terminal forms can coexist without interbreeding," Monjaraz-Ruedas writes in his abstract. "A broken ring species model preserves the geographic setting and fundamental features of an idealized model but accommodates varying degrees of gene flow restriction through evolutionary time. Members of the genus Calisoga are distributed around the Central Valley of California, and previous genetic studies have shown that this is a lineage-rich complex of mygalomorph spiders, with evidence to suggest that Calisoga might be a case of ring speciation. Here we examine broken ring species dynamics in Calisoga spiders, using UCEs and mitogenomes we test key predictions of timing, ancestry, connectivity and terminal overlap. I will discuss why ring species should not be viewed as homogeneous entities, but rather as heterogeneous units with different predicted evolutionary dynamics in different geographic parts of the ring."
Monjaraz-Ruedas joined the Marshal Hedin lab at San Diego State University as a postdoctoral research fellow in 2020. He studies "Phylogenomic, spatial phylogenetics and conservation prioritization in trapdoor spiders (and kin) of the California Floristic Province."
The Hedin lab focuses on arachnids, with particular emphasis on mygalomorph spiders and Opiliones (harvesters)," according to its website. "Species discovery, delimitation and description is important to us--although the biological world is amazingly diverse, most biodiversity remains undiscovered and undescribed. We spend a considerable amount of time conducting fieldwork--the western US and Appalachian mountains are hotspots for our research efforts. Cave arachnids interest us! In the lab we strive to be integrative, but our strength lies in molecular phylogeography and phylogenomics."

A well-deserved honor!
Kimsey, a recognized authority on insect biodiversity, systematics and biogeography of parasitic wasps, urban entomology, civil forensic entomology, and arthropod-related industrial hygiene, is a 34-year member of the UC Davis entomology faculty and a UC Davis alumna. She has directed the Bohart Museum since 1990.
Kimsey will be honored at the CA&ES Award of Distinction dinner on Thursday, Nov. 2 in the UC Davis Activities and Recreation Center (ARC) Ballroom. The event begins at 5:30 p.m. with a reception, followed by the dinner and awards ceremony. Registration ends Friday, Oct. 27; register online here.
"A renowned hymenopterist and taxonomist, Dr. Kimsey has brought worldwide distinction to our department, college, and the university for her research, teaching, public service, leadership, development funding, mentoring, and outreach," wrote Steve Nadler, then the chair of the Department of Entomology and Nematology, in his June nomination letter. "She works tirelessly to make insects and entomological knowledge more accessible to scientists and the public, and her influence and impact are felt internationally."
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 in Room 1124 of the Academic Surge Building, 455 Crocker Lane, 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.”
It is also the home of a year-around insect-themed gift shop (proceeds benefit the Bohart's educational activities) and a live “petting zoo” that includes Madagascar hissing cockroaches, stick insects and tarantulas. Children delight in holding the “hissers” and the walking sticks."
Unlike other directors of insect museums, which are working environments for scientists, Kimsey encourages visits by the public. Says UC Davis doctoral alumna Fran Keller, now a professor at Folsom Lake College: “Lynn….believes that allowing the public in to see the collection, to see scientists working, to talk to entomologists about insects is the most important thing we should be doing as entomologists. Lynn stressed that we should be willing to talk to anyone and provide information to anyone who asks a question about insects or who walks in the museum doors. She has focused on making the collection available for the public to see and to learn about what happens in an entomology museum.”
The Bohart takes its outreach programs to nearly 40 institutions annually. This includes schools, state and county fairs and libraries.
"Dr. Kimsey is a legend not only on the UC Davis campus but is called upon as an insect expert at the state, national and global levels," Nadler wrote. "She consults with international, national and state agencies; she identifies some 2000 insects every year for scientific collaborators, public agencies and the general public; she has answered an estimated 30,000 questions from the public and news media. They include bed bugs, yellowjackets, spiders, moths, butterflies, crane flies and Asian giant hornets (what the news media dubbed 'murder hornets'). She encourages a greater appreciation of insects through the Bohart Museum's many open houses, workshops and lectures. She also directs the support group, the Bohart Museum Society, and writes quarterly newsletters (nearly 100 to date) and fact sheets (80 to date) on insects and other arthropods). She compiled crucial information on human skin parasites and delusional parasitosis, important topics available on her website. The Bohart also sponsors summer BioBoot camps for middle-school and high school students."
Kimsey served as president of the International Society of Hymenopterists from 2002-2004, and as a member of the board of directors of the Natural Science Collections Alliance in 2000 and 2001. The Pacific Branch, Entomological Society of Ameica (PBESA) singled her out for its highest honor, the C. W. Woodworth Award, in 2020. She received the PBESA Systematics, Evolution, and Biodiversity Award in 2014 and was a member of 'The Bee Team' that won the PBESA Outstanding Team Award in 2013. The UC Davis Academic Senate honored her with its Distinguished Scholarly Public Service Award in 2016 in recognition of her outstanding work.
The nominating team described Kimsey as a favorite among the news media, with her ability to translate complex subjects into lay language, and her love of people. Over her 34 years at UC Davis, Dr. Kimsey has granted thousands of interviews to news outlets, including British Broadcasting System, New York Times, National Geographic, Associated Press, and Los Angeles Times.
Kimsey holds two degrees in entomology from UC Davis: a bachelor's degree (1976) and a doctorate (1979). She served served as the vice chair of the UC Davis Department of Entomology in 2005-2006 and again in 2009-2010.
