UC Davis third-year entomology student Sol Wantz, an intern at the Bohart Museum of Entomology, president of the UC Davis Entomology Club, and an undergraduate researcher in the Neal Williams' lab, shed light on "Grasshoppers, Crickets and Katydids" when she delivered a presentation at a recent Bohart Museum open house.
Jerusalem crickets, aka "potato bugs," drew the most interest.
The wingless insects, members of the family, Stenopelmatidae, are omniverous, feeding on both plants and animals, Wantz told the crowd. They are ground-dwelling insects found "mostly in North America, some in Asia and Africa," she said, and they include 7 genera and 67 species.
"They have a unique method of sound production," Wantz said. "They thump their abdomen against the ground to produce a surprisingly loud noise. Their thumping patterns can be used to identify their species."
Sol, who grew up in the Bay Area community of Belmont, is the first entomologist in her family. "My parents and brother all love insects, but I am the only one hoping to make a career out of entomology."
Jerusalem Cricket T-Shirt. The Bohart Museum sells a Jerusalem cricket t-shirt in its gift shop, the result of so many queries beginning with "What is that thing?" Kimsey's humorous answer, "basically Vienna sausages with bitey jaws," appears on the shirt. The art is the work of UC Davis student and Bohart volunteer Allen Chew, and the design by UC Davis doctoral alumnus Professor Fran Keller of Folsom Lake College, a Bohart Museum scientist.
Wantz also discussed grasshoppers and katydids. "The katydid genus Supersonus produces the highest frequency sound of any known animal, up to 150 kHz!" she said. "For reference, humans can only hear between 0 and 20 kHz."
Wantz grew up in the Bay Area community of Belmont. "My parents and brother all love insects, but I am the only one hoping to make a career out of entomology." Her parents, Adam Wantz and Patti Leggett-Wantz, were among those attending the seminar.
The Bohart Museum, located in Room 1124 of the Academic Surge Bulding, 455 Crocker Lane, is directed by Professor Jason Bond, the Evert and Marion Schlinger Endowed Chair in Insect Systematics, UC Davis Department of Entomology and Nematology; and associate dean of the UC Davis College of Agricultural and Environmental Sciences.
Two-Week Public Closure. Due to staff shortage, spring break, and winter quarter finals, the Bohart Museum will be closed to the public (walk-ins) for the next two weeks, Monday, March 18 through Friday, March 29. Previously scheduled group tours will continue to take place those two weeks. For more information, access the website at https://bohart.ucdavis.edu.

Just ask UC Davis entomology student Sol Wantz, who will present a talk on katydids (her favorite insect), grasshoppers and crickets at the Bohart Museum of Entomology open house, set from 1 to 4 p.m., Sunday, March 3 in Room 1124 of the Academic Surge Building, 455 Crocker Lane, UC Davis campus. It's free and family friendly.
We remember a crab spider that also found a katydid "incredibly fascinating." Umm, make that "nutritious." The spider grabbed the katydid on a Mexican sunflower (Tithonia rotundifola) in our garden, paralyzed it with a venomous bite, and then dragged it beneath the petals to eat it.
It's all about the cycle of life. Everything eats in the garden.
Sol Wantz triples as a curator intern at the Bohart Museum of Entomology, a student researcher in the lab of pollination ecologist and professor Neal Williams, and as president of the UC Davis Entomology Club.
“I'll be giving a overview of all of the major and most interesting--in my opinion--families of Orthoptera," she said. The order includes some 20,000 species worldwide.
Did you know that "the katydid genus Supersonus produces the highest frequency sound of any known animal, up to 150 kHz!" she asks. "For reference, humans can hear only between 0 and 20 kHz."
The Bohart Museum, directed by Professor Jason Bond, is located in Room 1124 of the Academic Surge Building, 455 Crocker Lane. It houses a global collection of eight million insect specimens, plus a live petting zoo (Madagasgar hissing cockroaches, stick insects, tarantulas and more) and an insect-themed gift shop stocked with T-shirts, hooded sweatshirts, books, posters, jewelry and insect-collecting equipment.

Themed "Grasshoppers, Crickets and Katydids," the open house will take place from 1 to 4 p.m., Sunday, March 3 in Room 1124 of the Academic Surge Building, 455 Crocker Lane, UC Davis campus. It's free and family friendly. Parking is also free.
UC Davis third-year entomology major Solea “Sol” Wantz, who triples as a curator intern at the Bohart Museum of Entomology, a student researcher in the lab of pollination ecologist and professor Neal Williams, and as president of the UC Davis Entomology Club, will discuss “Grasshoppers, Crickets and Katydids."
She'll deliver her presentation at 1 p.m., and questions and answers will follow. The venue: a classroom of the Museum of Wildlife and Fish Biology, located next to the Bohart Museum.
“I'll be giving a overview of all of the major and most interesting--in my opinion--families of Orthoptera," she said. The order includes some 20,000 species worldwide.
A few factoids she related:
- The katydid genus Supersonus produces the highest frequency sound of any known animal, up to 150 kHz! For reference, humans can only hear between 0 and 20 kHz.
- The family Myrmecophilidae, the “ant-loving crickets” are tiny, wingless crickets that live only in ant nests. “We even have these here in Davis, but they're hard to find unless you're digging through ant colonies,” Wantz says.
- Jerusalem crickets, also known as "potato bugs," have a unique method of sound production. "Rather than using their wings (they are actually wingless, she says) or another sound-producing organ, these crickets thump their abdomen against the ground to produce a surprisingly loud noise. Their thumping patterns can be used to identify their species."
“It's actually a grasshopper defense mechanism!” Wantz says. “When under stress--usually when they are grabbed, especially around the thorax-- grasshoppers vomit a foul-smelling/tasting liquid to ward off whatever predator is attacking them.”
Orthoptera (in ancient Greece, “ortho” means "straight,” and “optera” means "wings") is an order that includes grasshoppers, crickets, locusts and katydids. Grasshopper belong to the suborder Caelifera, and crickets and katydids to Ensifera.
Wantz, who decided at age 6 that she wanted to become an entomologist, is currently re-curating and reorganizing the Bohart's collection of several thousand specimens of Orthoptera.
"After finishing my undergraduate degree at UC Davis, I aim to enter a graduate program, potentially to explore my newfound interest in systematics. Ultimately, I hope to become a professor of entomology and lead my own research lab. This appeals to me because it presents the opportunity to weave together my knowledge of wild bee ecology and conservation, love of Orthoptera and museum work, and emphasis on professional outreach and public engagement."
The Bohart Museum, directed by Professor Jason Bond, houses a global collection of eight million insect specimens, plus a live petting zoo (Madagascar hissing cockroaches, stick insects, tarantulas and more) and an insect-themed gift shop stocked with T-shirts, hooded sweatshirts, books, posters, jewelry and insect-collecting equipment.

Ask her why people should be interested in insects, and she'll tell you. There's no "yecch" factor here: just the "ahh!" and "wow" factors.
Which is as it should be!
"First of all, bugs are just really cool!" says Sol, in her third year as an entomology major. "Second, they are extremely important in just about every aspect of life, even if most people don't like to think about that. Just as an example, almost all the food we eat was either directly or indirectly insect-pollinated. Fruits are obvious, but even all the meat we eat comes from animals that ate plants that were pollinated by insects. My field of study, wild bees, is especially important in this exact context because they cannot pollinate every crop. For example, alfalfa and tomatoes are two of our most common crops that cannot be pollinated by honey bees."
Sol, who grew up in the Bay Area community of Belmont, is the first entomologist in her family. "My parents and brother all love insects, but I am the only one hoping to make a career out of entomology. My dad is a forensic economist, my mom is a photographer, and my brother works as a distributor in the car wash industry."
What sparked her interest in entomology?
The UC Davis Entomology Club draws about 25 people to its weekly meetings, held on Thursdays at 6 p.m. in 122 Briggs Hall. (See Instagram account). "But this quarter a few of our meetings have had 40-plus," Sol said. "Every week, I lead a bug-themed activity, which ranges from professional pinning demos, guest speakers, and arboretum field trips, to movie nights, bug-themed trivia, and show-and-tell nights. At least once or twice a quarter, we do an overnight camping trip in Pope Valley to look for bugs. This fall, our camping trip had 25 insect-enthusiasts, which was a ton of fun but definitely a hassle for me to plan!"
Sol is passionate about her research. In the Williams lab, she is working on a project led by graduate student Elizabeth Reyes-Gallegos that is focused on comparing the functional traits of wild bees to floral functional traits. "Early this quarter, we finished our first field season sampling at plots at the Bee Biology Facility (Harry H. Laidlaw Jr. Honey Bee Research Facility on Bee Biology Road), so we are still in the early stages of the project," Sol said. "Since spring quarter, I have been working very closely with just about every bee we have collected because I have been dissecting their proboscises as well as pinning and labeling them. Because I have worked so closely with the bees' 'tongues,' I will be branching off slightly from Elizabeth's main focus to look for intraspecific variation in tongue lengths and body size. Currently, I am working closely with Elizabeth and Neal to fully flesh out this project."
At the Bohart Museum, Sol is involved in general curation: pinning, labeling and integrating specimens into the collections. She is currently organizing the Orthoptera collection, which includes grasshoppers, locusts, and crickets. And she's beginning species identification of katydids (Tettigoniidae).
Sol is a fixture at the Bohart Museum open houses. "I started volunteering with the Bohart in winter of 2022 at the Biodiversity Museum Day," she related. "In the months following that, I became a regular volunteer at their outreach events. This was also before I became president of the Entomology Club, but during that time I was helping out as much as I could with various club outreach opportunities, like birthday parties or campus festivals. In July of 2022, the Bohart hired me as an undergraduate intern and I have been working there ever since!"
Another project: Sol is spearheading the Bohart Museum's open house on "Grasshoppers, Crickets and Katydids," from 1 to 4 p.m., Sunday, March 3 in Room 1124 of the Academic Surge Building, 455 Crocker Lane, UC Davis campus. (See Bohart Museum schedule)
How would she describe herself to a stranger? "I am an ambitious, hard-working, and outgoing future career entomologist with a special interest in wild bees and katydids. I love to explore the outside looking for bugs, and have dreams of traveling the world for that very purpose. When I don't have insects on my mind, I like to spend my time playing violin, drawing, and surrounding myself with my friends and family."
She's played the violin for about 11 years; in high school she volunteered to teach fourth and fifth graders how to play the instrument.
Sol is glad she chose UC Davis to study entomology. "Overall, I really like how UC Davis is inclusive and welcoming. I also love that we have the arboretum, which has some really great places to find bugs. And of course, I'm especially glad that entomology is a major here and I absolutely love the little entomologist community we've built."
From a childhood loving insects to a senior majoring in entomology at UC Davis, to a researcher studying wild bees to a curator working in the Orthoptera collection at the Bohart Museum, what's next?
"After I graduate from UC Davis, I would like to go to graduate school and study systematics," Sol related. "Although I am also extremely interested in ecology, I have developed an interest in systematics and museum work over the last year. Ultimately, I think I would like to become a professor of entomology and maybe someday run my own lab."
Professor Sol Wantz...That has a nice ring to it!
