Scientists also encouraged the visitors to touch or handle a few of the live specimens, including millipedes, Madagascar hissing cockroaches and walking sticks.
Doctoral candidates Emma Jochim and Xavier Zahnle of the Jason Bond arachnology lab opened the event with a 30-minute mythbusting session moderated by doctoral student Iris Quayle of the Bond lab. (See the UC Davis Entomology and Nematology website for which myths they busted, and watch their YouTube-posted video on brown recluse spiders.)
The trio studies with major professor Jason Bond, the Evert and Marion Schlinger Endowed Chair in Insect Systematics, UC Davis Department of Entomology and Nematology, and associate dean, College of Agricultural and Environmental Sciences.
Following the mythbusting, Jochim, Zahnle and Quayle and researcher and project scientist Jim Starrett of the Bond lab (he holds a doctorate in genetics, genomics and bioinformatics from UC Riverside), teamed with Davis students to showcase critters. Elijah Shih, a third-year UC Davis transfer student who plans to pursue a career in veterinary medicine, displayed his isopods. Bohart Museum research associate Brittany Kohler, the "zookeeper" of the Bohart's live petting zoo, provided tarantulas, black widows, a brown widow, a centipede, Madagascar hissing cockroaches, stick insects and ironclad beetles, among others.
The tarantulas sport such names as "Princess Herbert," "Peaches" and "Coco McFluffin." Starrett wowed the crowd at two "feeding times" for Princess Herbert. The menu? Crickets, which she instantly devoured. Princess Herbert, the Bohart Museum's oldest tenant in its petting zoo, is a Brazilian salmon-pink bird-eating tarantula (Lasiodora parahybana).
Kim Crawford of Cameron Park and her daughter, Emma, 10, loved the millipedes. Valentina Leijja, 8, of Mexico City, attending with her parents, Martha Leija and Mario Preciado, asked scores of questions of doctoral student Emma Jochim and then visited the Lepitoptera section to see the butterflies and moths, being shown by Bohart associate Greg Kareofelas and Kohler.
Meanwhile, the arts-and-crafts table came to life with newly sculptured arachnids, carefully modeled of clay. (More on pending Bug Squad posts.)
Tabatha Yang, the Bohart Museum's education and outreach coordinator, estimated that more than 350 attended. "The open house featured arachnids, myriapods, isopods and even some tardigrades (also known as water bears)," she said.
A tardigrade scupture, the work of Solomon Bassoff, fronts the entrance to the Academic Surge Building. The Bohart Museum houses one of the world's largest collections of tardigrades. The current collection includes some 25,000 slide-mounted specimens. In a recent newsletter, Bohart Museum director Lynn Kimsey described the water bear as “one of the most peculiar and indestructible groups of animals known. The microscopic and nearly indestructible tardigrade can survive being heated to 304 degrees Fahrenheit or being chilled for days at -328 F. And, even if it's frozen for 30 years, it can still reproduce." See video on EurekAlert.
The Bohart Museum, part of the UC Davis Department of Entomology and Nematology, houses a global collection of eight million insect specimens, plus the live petting zoo, and a gift shop stocked with insect-themed books, posters, jewelry, t-shirts, hoodies and more. Founded in 1946 and named for UC Davis professor Richard Bohart, it is dedicated to "understanding, documenting and communicating terrestrial arthropod diversity." It is open to the public Mondays through Thursdays, from 8 a.m. to noon, and 1 to 5 p.m. More information is available on the Bohart website at https://bohart.ucdavis.edu or by emailing bmuseum@ucdavis.edu.
The Bohart Museum is now preparing for the annual campuswide UC Davis Picnic Day on Saturday, April 15. This year is the 109th annual.

It's a myth. There are no established populations of Loxoceles reclusa in California, doctoral candidates Emma Jochim and Xavier Zahnle of the Jason Bond arachnology lab related during their 30-minute mythbusting at the Bohart Museum of Entomology open house, "Many Legged-Wonders," on Saturday, March 18. First-year doctoral student Iris Quayle of the Bond lab moderated the session.
They study with their major professor Jason Bond, the Evert and Marion Schlinger Endowed Chair in Insect Systematics, UC Davis Department of Entomology and Nematology, and associate dean, College of Agricultural and Environmental Sciences.
Jochim related that a person claiming to have been bitten by a brow recluse spider in California may have recently returned from a state where they are established or that they handled one that was shipped from that area.
That brings to mind the research of Rick Vetter of UC Riverside and his piece on "Myth of the Brown Recluse: Fact, Fear and Loathing."
"This website presents evidence for the lack of brown recluse spiders as part of the Californian spider fauna. Unfortunately, this contradicts what most Californians believe; beliefs that are born out of media-driven hyperbole and erroneous, anxiety-filled public hearsay which is further compounded by medical misdiagnoses. Although people are free to disagree, this opinion has come about after more than two decades of constant research resulting in many publications in the scientific and medical literature."
Vitter goes on to say: "Spiders are one group of arthropods that are very well known by the common person yet are terribly misunderstood; because of the rare occasion of a deleterious venom incident, almost all spiders are lumped into the category of 'squish first and ask questions later.' There are remarkably few spiders in California that are capable of causing injuries via biting. Overall, spiders are beneficial to humans in that they eat many pestiferous insects that either infest our foods (many phytophagous insects), are vectors of disease (flies, mosquitoes) or are aesthetically-challenged (cockroaches, earwigs). Unfortunately, humans have a low tolerance for spiders in their homes, either because spiders are symbols of danger, unkemptness or arachnophobia. One of the first steps one should take in dealing with these critters should be to identify them properly before blasting them with pesticide and/or getting hysterical."
Meanwhile, listen to UC Davis arachnologists:
Said one attendee: "Dr. Rick Vetter at U. C. Riverside fought the battle for the truth for decades and finally pretty much threw up his hands in defeat. He just couldn't get the media or California medical profession to stop claiming the Brown Recluse is HERE and diagnosing every little spot or open sore as a spider bite. My opinion is that people LIKE to think they were bitten by a brown recluse and wear it as a badge of honor. So much more thrilling than saying bacteria infection.”

That includes spiders. You've seen those adorable jumping spiders with green "fangs" (chelicerae), right? But have you even seen the green lynx spiders?
A few years ago we spotted a green lynx spider, Peucetia viridans, on a pink rockrose blossom. Arachnologists tell us it's usually found on green plants--green on green--which is exactly why we can't find it!
Meanwhile, want to see and learn about spiders?
Then you'll want to attend the Bohart Museum of Entomology open house, themed "Many Legged Wonders," from 1 to 4 p.m., Saturday, March 18 in Room 1124 of the Academic Surge Building, 455 Crocker Lane. Yes, it's free. So is parking. And yes, it's family friendly. The family arts-and-crafts activity, coordinated by UC Davis doctoral candidate Emma Jochim, of the Jason Bond arachnology lab will be working with model clay to mold arachnids and myriapods.
Jochim and fellow doctoral candidate Xavier Zahnle of the Bond lab will answer your questions about spiders from 1 to 1:30. First-year graduate student Iris Quayle of the Bond lab will moderate the session. Lab members also will show some "rarer live arachnids such as 'vinegaroons' and 'whip spiders' in addition to tarantulas and scorpions," Jochim said. "We will also have millipedes that people can handle and many species of isopods."
A showing of live animals and specimens is scheduled from 1:30 to 4 p.m. Elijah Shih, a third-year UC Davis transfer student who plans to pursue a career in veterinary medicine, will show his isopods. Bohart Museum research associate Brittany Kohler, the "zookeeper" of the Bohart petting zoo, will show the current tenants, which include tarantulas, black widows, a brown widow, a centipede, Madagascar hissing cockroaches, stick insects and ironclad beetles.
Of course, the tarantulas sport such endearing names as "Princess Herbert," "Peaches" and "Coco McFluffin." Much better than "Killer," "Fang" or "Monster Man."

Oh? In California?
That leads to such questions as:
- "Does California have brown recluse spiders?"
- "Do millipedes really have 1000 legs?"
- "Are baby scorpions deadlier than adults?"
Those are some of the topics that UC Davis doctoral candidates Emma Jochim and Xavier Zahnle of the Jason Bond arachnology lab will discuss when they dispel myths about spiders and millipedes at the Bohart Museum of Entomology open house on Saturday, March 18. The theme: "Many-Legged Wonders."
The Bond lab's question-and-answer session about spider myths is set from 1 to 1:30 p.m. First-year doctoral student Iris Quayle will moderate. Lab members also will show some "rarer live arachnids such as 'vinegaroons' and 'whip spiders' in addition to tarantulas and scorpions," Jochim said. "We will also have millipedes that people can handle and many species of isopods."
Professor Bond is the Evert and Marion Schlinger Endowed Chair in Insect Systematics, UC Davis Department of Entomology and Nematology, and associate dean, College of Agricultural and Environmental Sciences.
- Princess Herbert, a Brazilian salmon-pink bird-eating tarantula (Lasiodora parahybana), age estimated to be around 20 (current oldest resident)
- Peaches, a Chilean rose hair tarantula (Grammostola rosea)
- Coco McFluffin, a Chaco golden knee tarantula (Grammostola pulchripes)
- Beatrice, a Vietnamese centipede (Scolopendra subspinipes), newest resident
- Two black widows (Latrodectus hesperus)
- One brown widow (Latrodectus geometricus)
Among the other residents are Madagascar hissing cockroaches, a giant cave cockroach, stick insects, a bark scorpion and ironclad beetles. A family arts-and-crafts activity is also planned.
The family arts-and-crafts activity, being planned by Jochim, will be molding arachnids and myriapods using model clay.

A BioBlitz is set from 9 to 11 a.m., Saturday, April 29 in the UC Davis Arboretum and Public Garden. It's being hosted by UC Davis doctoral student Grace Horne of the Department of Entomology and Nematology.
Participants will meet in at the Wyatt Deck (previously the BioBlitz was scheduled for the Carolee Shields White Flower Garden and Gazebo.)
"I am excited about the location change because we will be located next to two biodiversity hubs: The T. Elliot Weier Redwood Grove and the Mary Wattis Brown Garden of California Native Plants," said Horne, a member of the laboratory of urban landscape entomologist Emily Meineke, assistant professor, UC Davis Department of Entomology and Nematology.
Reservations (free) are underway here.
“We need your help to track and identify the wildlife in Davis!" said Horne, a member of the laboratory of urban landscape entomologist Emily Meineke, assistant professor, UC Davis Department of Entomology and Nematology. "Participants will take photos of plants, animals, and fungi, and upload these observations to the community science platform, iNaturalist. All you need to bring is a smartphone or a photo-taking device. We will have a table with small lenses, bug boxes, field guides, insect specimens, and more to help you make observations of wildlife. Local experts will also be available to assist in identifying the wildlife."
This event will be hosted in coordination with the City Nature Challenge Sacramento. The City Nature Challenge (CNC) is an annual international competition among cities with the goal of documenting the most biodiversity within a four-day period.
This year the challenge will occur from April 28 to May 1, "so any observations of wildlife that are uploaded to iNaturalist will contribute to the 2023 CNC," Horne said. "At the end of the CNC, the region with the most observations wins. We are looking to make as many quality observations as we can during the Davis Bioblitz, so stop by the Shields Gazebo to help contribute observations to the Greater Sacramento Region!”
Horne's undergraduate thesis about the effects of the decline of ash trees on native caterpillars, scored the cover of the February edition of the journal Environmental Entomology. The paper, “Specialist Herbivore Performance on Introduced Plants During Native Host Decline,” is co-authored by Ria Manderino of the Oak Spring Garden Foundation, Upperville, VA and Samuel Jaffe of The Caterpillar Lab, Marlborough, N.H. “Our publication highlights the importance of multispecies assessments of host plant acceptance,” said Horne, who studies plant-insect interactions, urban ecology, global change biology, natural history and community science in the Meineke lab.
