Following on the heels of its 2022 open house on "Eight-Legged Wonders," the Bohart Museum of Entomology will showcase spiders, millipedes, centipedes, scorpions, tarantulas and isopods—and more—at its open house themed “Many-Legged Wonders” on Saturday, March 18.
The event, free and family friendly, will be from 1 to 4 p.m. in Room 1124 of the Academic Surge Building, 455 Crocker Lane, UC Davis campus. A family arts and crafts activity is also planned.
Tabatha Yang, education and outreach coordinator for the Bohart announced that doctoral candidates Emma Jochim and Xavier Zahnle of the Jason Bond arachnology lab will dispel myths about spiders and millipedes at a question-and-answer session from 1 to 1:30. Doctoral student Iris Quayle will moderate.
From 1:30 to 4 p.m., will be the general open house with a showing of live animals and specimens. UC Davis student Elijah Shih will display his isopods, which are crustaceans and have 14 legs.
Shih, a third-year transfer student studying neurobiology, physiology and behavior, says that “Isopods come in many morphs and sizes. There are many colorful and beautifully patterned isopods, some natural, some man made. Isopods are crustaceans and require moisture to breathe and molt properly. Some species have the ability to conglobate or roll up in to the ball where as others do not. They are great for helping create a bioactive system for reptiles, planted tanks, and a great feeder for young reptiles and amphibians.”
“There are many isopod species in the world,” Shih related, “and at least five common isopod species that are found in California: Porcellio laevis, Porcellio scaber, Armadillidium vulgare, Porcellio dilatatus, and Cubaris marina. Their morphs are considered wild type.”
Shih, who hopes to pursue a career in veterinary medicine, said he houses “many reptiles, both aquatic and terrestrial, such as the box turtle and gargoyle gecko. I wanted to create bioactive environments for my reptiles—(mainly to not have to pick up the feces)-- so I looked for ways to make that possible. I need something that was small, agile, prolific, and safe to be eaten. Isopods, better known as Rollie pillows or pill bugs, are the best solution for me. I had my isopods, but to complete the cleanup crew, I added springtails to help clean up any leftover food, but more importantly, the mold.”
Bohart Museum research associate Brittany Kohler, the "zookeeper" of the Bohart petting zoo, says the current residents include:
- 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.
The Bohart Museum, directed by UC Davis distinguished professor Lynn Kimsey, houses a global collection of eight million insect specimens, plus the petting zoo and a gift shop stocked with insect-themed books, posters, jewelry, t-shirts, hoodies and more. Dedicated to "understanding, documenting and communicating terrestrial arthropod diversity," the Bohart Museum was founded in 1946 and named for UC Davis professor and noted entomologist Richard Bohart. The insect museum is open to the public Mondays through Thursdays, from 8 a.m. to noon, and 1 to 5 p.m.

Her seminar also will be virtual. The Zoom link is https://ucdavis.zoom.us/j/95882849672. A coffee social will take place in 158 Briggs from 3:30 to 4:10 p.m.
Chamberland is a member of the laboratory of Jason Bond, associate dean, UC Davis College of Agricultural and Natural Resources, and professor and the Evert and Marion Schlinger Endowed Chair, UC Davis Department of Entomology and Nematology.
“Net-casting spiders (Deinopidae) comprise three genera with enigmatic evolutionary histories. Deinopisand Asianopis, the ogre-faced spiders, are best known for their giant light-capturing posterior median eyes (PME), whereas Menneus does not have enlarged PMEs,” Chamberland says in her abstract. “Molecular phylogenetic studies have revealed discordance between morphology and molecular data. We employed a character-rich, ultra-conserved element (UCE) dataset and a taxon-rich cytochrome oxidase I (COI) dataset to reconstruct a genus-level phylogeny of Deinopidae, aiming to investigate the group's historical biogeography, and examine PME size evolution. Although the phylogenetic results support the monophyly of Menneus and the single reduction of PME size in deinopids, these data also show that Deinopis is not monophyletic. Deinopid biogeographic history reflects the separation of Western Gondwana as well as long-distance dispersal events.”
Chamberland, who studies the evolution and biogeography of spiders, joined the Bond lab in 2021. She holds a doctorate in biology (2020) from the University of Vermont, Burlington, where she studied with Ingi Agnarsson. Her dissertation: "From Gondwana to GAARlandia: Molecular Phylogenetics and Historical Biogeography of Spiders." She received her bachelor's degree in biology and anthropology in 2013 from the University of Vermont.
“As an undergraduate at the University of Vermont, I was introduced to deinopids, the ogre-faced spiders, and it was love at first sight,” Chamberland related. “With a wide range of dispersal propensities and diverse hunting strategies, spiders have been a rich source for me to explore biogeographic and evolutionary questions. I would like to continue my work with historical biogeography and spiders after my postdoc and help foster the upcoming generation of arachnologists. I enjoy teaching, especially through the lens of phylogenetics and systematics, and I am working towards finding a teaching career where I can teach, mentor, and continue to ask evolutionary questions.”
Chamberland is the lead author of “Biogeography and Eye Evolution of the Ogre-faced Spiders," published Oct. 22, 2022 in Scientific Reports and co-authored by Ingi Agnarsson, Iris Quayle, Tess Ruddy, James Starrett and Jason Bond.
Chamberland and Bond co-hosted the 2022 American Arachnological Society Summer Symposium at UC Davis and she also delivered a research presentation at the symposium. At both UC Davis and at the University of Vermont, she has led and taught lab and field techniques, molecular methods and data analyses, and arachnology to high school, undergraduate, and graduate students, resulting in publications on systematics, evolution, and biogeography of spiders.
She earlier served as the invertebrate collections manager at the Zadock Thompson Zoological Collections (2020-2021), University of Vermont.
The department seminars, coordinated by urban landscape entomologist Emily Meineke, assistant professor, are held on Wednesdays through March 15. (See schedule.) Eight of the 10 will be in-person in 122 Briggs Hall, and all will be virtual.

The Bohart Museum of Entomology open house, "Eight-Legged Encounters," co-sponsored by the American Arachnological Society (AAS) and held June 25 in the Academic Surge Building, drew more than 250 attendees and 40 volunteers.
"It was an absolutely amazing event!" said arachnologist Jason Bond of UC Davis, co-host of the AAS meeting.
"We were pleased to see such a large turnout from the community but even more so delighted to see so many young people," said Bond, associate dean, UC Davis College of Agricultural and Environmental Sciences, and professor and the Evert and Marion Schlinger Chair in Insect Systematics, UC Davis Department of Entomology and Nematology. "There were over 40 volunteer arachnologists representing a national and international contingent of expertise. While we couldn't have done it without them, they also contributed a tremendous amount of expertise, excitement, and energy to the event."
Hebets, the Charles Bessey Professor at UNL and president of the Animal Behavior Society, co-hosted the open house as part of a U.S. National Science Foundation grant, “Eight-Legged Encounters” that she developed as an outreach project to connect arachnologists with communities, especially youth. (See her website).
Some 20 activity tables lined the hallway of the Academic Surge Building.
"Our Eight-Legged Encounters event at the UC Davis Bohart Museum far exceeded our expectations!" said Professor Hebets. "It was an incredibly successful event, with well over 250 attendees and more then 40 volunteers, many of which were graduate students and post-doctoral researchers from across the country and world. There is no doubt it was a life-changing experience for some of our young attendees as well as some of the student volunteers. I am so very thankful for the help and support we received from the Bohart Museum and from Dr. Jason Bond and his laboratory. It could not have happened without them."
Bond co-hosted the AAS conference, held June 26-30 on the UC Davis campus, with Lisa Chamberland, postdoctoral research associate of the Bond lab, and Joel Ledford, assistant professor of teaching, Department of Plant Biology, College of Biological Sciences. Chamberland coordinated the spider-species naming project with second-year doctoral student Emma Jochim of the Bond lab and incoming doctoral student Iris Bright, who starts this fall. No winner has yet been announced.
Some of the displays:
- "Black widow hourglasses are actually on their bellies. These spiders are actually social!"--Laura
- "I want to learn what is in spider venom and how it helps catch prey."--Greta
- "Trapdoor spiders live in California and eat bugs. There are many unknown species. I use DNA to find new species."-Jim
The Bohart Museum also drew scores of visitors during the 1 to 4 p.m. open house. Entomologist Jeff Smith, curator of the Lepidoptera collection and Bohart associate Greg Kareofelas showed visitors butterfly and moth specimens, while other volunteers discussed other collections, including spider wasps and small-headed flies. The museum, directed by UC Davis distinguished professor Lynn Kimsey, houses a global collection of eight million insect specimens, as well as a live "petting zoo" (Madagascar hissing cockroaches, stick insects and tarantulas) and an insect-themed gift shop.

One of the activities at the Bohart Museum of Entomology open house, "Eight-Legged Encounters," set from 1 to 4 p.m., Saturday, June 25, will be a "Name-That-Spider-Species" contest, open to students 18 and under. The focus: a male trapdoor spider, a new species from the genus Promyrmekiaphila.
The event will be co-hosted by the Bohart Museum and the American Arachnological Society (AAS).
The open house will kick off the annual meeting of AAS, which meets June 26-30 on the UC Davis campus, said arachnologist Jason Bond, associate dean, College of Agricultural and Environmental Sciences, and the Evert and Marion Schlinger Endowed Chair in Insect Systematics, UC Davis Department of Entomology and Nematology. Professor Bond is chairing the AAS conference with Lisa Chamberland, postdoctoral research associate of the Bond lab, and Joel Ledford, assistant professor of teaching, Department of Plant Biology, College of Biological Sciences.
Chamberland, who holds a doctorate from the University of Vermont where she studied the historical biogeography of net-casting spiders (Deinopis) and spiny-backed orb-weavers (Gasteracantha) in the Caribbean, is coordinating the spider-species naming project with doctoral student Emma Jochim of the Bond lab and incoming doctoral student Iris Bright, who starts this fall.
"The genus Promyrmekiaphila is a group of trapdoor spiders that construct silk-lined burrows with wafer-like trapdoor lids, usually decorated with plant material or substrate," Jochim explained. "It's found generally in the Southern Bay Area. As of now there are only two species in the genus, so this new species will be the third!"
The student who wins the contest will have the honor of naming the new species, and an acknowledgment will appear in a forthcoming scientific paper, said Bond.
At the open house, some 20 exhibits and activities--educational and entertaining--will be set up in the hallway of the Academic Surge Building. “There will be everything--spider specimens, live arachnids, activities, artwork, etc., at the open house," said Bond, adding that a powerhouse of the nation's arachnologists will participate.
AAS member Eileen Hebets, professor at the University of Nebraska, Lincoln, is co-hosting the open house as part of a U.S. National Science Foundation grant, “Eight-Legged Encounters” that she developed as an outreach project to connect arachnologists with communities, especially youth. She seeks to educate the public “about the wonders of biology and the possibility of scientific discovery using a charismatic and engaging group of animals--arachnids. Arachnids (spiders and their relatives) are ubiquitous, thriving in most habitable environments on our planet (including underwater),” as mentioned on her website, https://hebetslab.unl.edu/
Professor Bond offers five good reasons to like spiders:
- Spiders consume 400-800 million tons of prey, mostly insects, each year. Humans consume somewhere around 400 million tons of meat and fish each year.
- Spider silk is one of the strongest naturally occurring materials. Spider silk is stronger than steel, stronger and more stretchy than Kevlar; a pencil thick strand of spider silk could be used to stop a Boeing 747 in flight.
- Some spiders are incredibly fast--able to run up to 70 body lengths per second (10X faster than Usain Bolt).
- Although nearly all 47,000-plus spider species have venom used to kill their insect prey, very few actually have venom that is harmful to humans.
- Some spiders are really good parents--wolf spider moms carry their young on their backs until they are ready to strike out on their own; female trapdoor spiders keep their broods safe inside their burrows often longer than one year, and some female jumping spiders even nurse their spiderlings with a protein rich substance comparable to milk.
Hebets says that as a scientist, a mother and an educator, she often sees "the disconnect between youth and the world around them; between problem solving skills, observation skills, critical thinking, natural curiosity and the more traditional formal teaching programs experienced by many students. Youth are innately curious and tremendously creative and my aim is to leverage these traits for their own educational advancements in a fun and engaging manner.” To date, Hebets and her collaborators have developed more than 25 modular activity stations “encompassing arts and crafts, experiments, games, and other hands-on activities." They include classification and taxonomy, spiders and silk, path of predators, and hands-on science.
The Bohart Museum, directed by UC Davis distinguished professor Lynn Kimsey, houses a worldwide collection of eight million insect specimens; a live "petting zoo" (Madagascar hissing cockroaches, stick insects and tarantulas) and an insect-themed gift shop.
In addition to the open house, AAS has scheduled a series of arachnid lectures, free and open to the public, from 7:30 to 9 p.m. Tuesday, June 28, in the newly constructed 600-seat lecture hall, California Hall.

The free, public open house. featuring spiders and other arachnids, promises to be one of the biggest events--if not the leggiest!--of the year on the UC Davis campus and beyond. The Bohart Museum is located in the Academic Surge Building, Crocker Lane.
A "powerhouse" of arachnologists will be participating, said Jason Bond, associate dean, College of Agricultural and Environmental Sciences, and the Evert and Marion Schlinger Endowed Chair in Insect Systematics, UC Davis Department of Entomology and Nematology. He will be hosting the conference with Lisa Chamberland, postdoctoral research associate, Department of Entomology and Nematology, and Joel Ledford, assistant professor of teaching, Department of Plant Biology, College of Biological Sciences.

Also at the open house, plans call for “A Name-That-Spider-Species" contest, coordinated by postdoctoral fellow Lisa Chamberland and PhD students Iris Bright and Emma Jochim of the Bond lab. “We'll have an exhibit at the event with details on the spider,” Bond said. It's a trapdoor spider from the genus Promyrmekiaphila. “We'd like to restrict naming suggestions to be youths attending the event, students 18 years and younger."
