They're featured prominently on the newly available Bohart Museum of Entomology hooded sweatshirts, the work of artist Charlotte Herbert Alberts and designer Fran Keller.
Tardigrades can survive in many extreme conditions, including space, and they're sure to survive in the Bohart--unless they're all gone soon.
Available in red, gray and black, from sizes extra small to extra extra large, they'll be offered in the Bohart Museum gift shop during the UC Davis Biodiversity Museum Day on Saturday, Feb. 16. Proceeds from the sales benefit the insect museum's educational activities.
The artist? Charlotte Herbert Alberts, an entomology doctoral candidate who studies Asilidae (Assassin flies) with her major professor, Lynn Kimsey, director of the Bohart and UC Davis professor of entomology. Alberts cleverly drew a "Bohart Republic" water bear flag, a take-off of the California Bear Flag, except hers features an entomologist, insect net in hand, riding a huge tardigrade.
The front features a tardigrade face inside a Bohart logo, a design by Fran Keller, an assistant professor at Folsom Lake College. She received her doctorate in entomology from UC Davis, studying with Kimsey and designed many of the shirts, sweatshirts and posters in the Bohart Museum's gift shop.

No, time's fun when you're studying flies!
Take it from the fly researchers at the University of California, Davis, who will present their work at the Bohart Museum of Entomology open house from 1 to 4 p.m., Saturday, Jan. 12 in Room 1124 of the Academic Surge Building, Crocker Lane. The event, themed “Time's Fun When You're Studying Flies," is free, open to the public, and family friendly.
The open house will showcase botflies, spotted-wing drosophilas, assassin flies, Mediterranean fruit flies, mosquitoes and other members of the Diptera order. Ten scientists, including undergraduate students, graduate students and a visiting scholar, will participate. They will displaying specimens, photos and field equipment and chat with the public.
"Besides checking out the flies, this is also a good time for visitors to inquire about graduate school, ask about starting research projects, and to meet people working in forensics, evolution, agriculture, animal behavior, genetics, geography, and home pests, among other topics," said Tabatha Yang, education and outreach coordinator.
Entomologist Jeff Smith, who curates the Bohart's butterfly and moth section, will be on hand to open the Diptera section. "He will dust off and put on his pest industry hat to talk about those relevant flies," Yang said.
A family craft activity is also planned.
Among the fly researchers participating is fourth-year doctoral candidate Charlotte Herbert Alberts, who studies assassin fly (Asilidae) systematics with major professor Lynn Kimsey, director of the Bohart Museum of Entomology and professor of entomology, UC Davis Department of Entomology and Nematology.
“Assassin flies are one of the only families of flies that are predatory (on other insects) both in their larval and adult stages,” Alberts says.
Other interesting facts about assassin flies:
- They are venomous! Their venom both immobilizes their prey and starts extra-oral digestion.
- They have very fancy facial hair (beards and mustaches) called a mystax, thought to protect their face while they catch and eat their prey.
- Some assassin flies are very selective in their prey choice and may have specialized venom to help them overcome their prey.
- There are more than 7,500 species found all over the world!
Graduate student Socrates Letana, who also studies with major professor Lynn Kimsey. researches the evolution and diversification of botflies (Oestridae) "in the global mammal host-space with special emphasis on the New World." Part of his research interests include Diptera systematics, biogeography and Southeast Asian biodiversity. He is a research associate with the California State Collection of Arthropods, California Department of Food and Agriculture.
The larvae of botflies are internal parasites of mammals; some species grow in the host's flesh and others within the gut. The Dermatobia hominis is the only species of botfly known to parasitize humans routinely.
Said Letana: "I will be using the pinned and alcohol-preserved materials from the Bohart collection. Also, I am thinking of using my laptop just to show some photos from other museum collections. Some people might be a little squeamish about this group of flies and I will try my best not to scare them away."
UC Davis doctoral student Caroline Wright Larsen of the Graduate Group in Ecology, will discuss her research on non-native tephritid flies, including the Mediterranean fruit fly. She studies with major professor James R. Carey, distinguished professor of entomology. A Bio Boot Camp instructor, part of the Bohart Museum program, she attended Bryn Mawr College outside of Philadelphia for her undergraduate degree, "during which I spent six months living in Kruger National Park, South Africa doing insect biodiversity research." She began her graduate studies in 2011 at U.C. Davis "where I explore the ways in which difficult-to-detect populations of non-native tephritid flies move over space and time in California."
UC Davis undergraduate researcher Cindy Truong of the Joanna Chiu lab, will be showing flies in various life stages and have coloring pages for kids. "We primarily study circadian rhythm, which is the sleep and wake cycle. More specifically we study the mechanisms in which 'clock proteins' go through in order to maintain this cycle." She will expand on "How flies tell time.”
Christine Tabuloc, an undergraduate researcher in the Chiu lab. will discuss her work on fruit flies. "My current focus is to investigate the effects of climatic change on gene expression of an invasive pest and determine whether there is a correlation to resistance and survival," she said. "In addition to pest management research, I am also studying a kinase of a core clock protein in Drosophila melanogaster and hoping to dissect its functional contribution to the molecular oscillator."
Others from the Chiu lab participating will be Yao Cai, a doctoral graduate student who studies genetic mechanisms underlying the regulation of organismal behavior, and undergraduate researcher Christopher Ochoa.
Among the other scientists participating:
- Kathlyne-Inez Soukhaseum of the Frank Zalom lab will talk about her research on the spotted-wing drosophila, Drosophilasuzukii, a major agricultural pest that invaded California in 2008.
- Danielle Wishon, a forsenic entomologist who holds a bachelor's degree in entomology from UC Davis, will discuss bed bugs and other pests.
- Nermeen Raffat, visiting scholar in the Sharon Lawler lab, will focus on mosquito larvae. He is working on "the effect of copper sulphate and other toxicants on the development and anti-predatory behavior of the mosquitoes larvae."
The Bohart Museum, founded in 1946 by UC Davis entomologist Richard “Doc” Bohart (1913-2007), is the home of nearly eight million insect specimens, plus a year-around gift shop and live "petting zoo" that includes Madagascar hissing corckroaces, stick insects, tarantulas and praying mantids. The gift shop is stocked with newly published calendars, books, jewlery, t-shirts, insect-collecting equipment, insect-themed candy, and stuffed animals.
The Bohart Museum is open to the general public Mondays through Thursdays, from 9 a.m. to noon and from 1 to 5 p.m., plus occasional, weekend open houses. Admission is free. The next weekend open house is from 1 to 4 p.m., Sunday, Nov. 18 and centers around urban entomology..
This particular monarch chrysalis was not the immature stage of a monarch butterfly but a piñata--complete with an emerging parasitoid--cleverly crafted by UC Davis doctoral student Charlotte Herbert Alberts and her husband, George, and recent UC Davis graduate Emma Cluff.
The sculpted larva of what monarch enthusiasts call the "dreaded tachinid fly" protruded from the piñata. It was the first to go, victim of a direct hit.
The annual pre-Halloween party presented by the Bohart Museum Society, draws assorted arthropod costumes, from assassin bugs to praying mantids to peacock spiders, but the annual piñata breaking contest, is always "the" smash hit. You can almost feel the whops, wallops and whammies, along with the one-two-three punches (each hitter gets three swings) as the crowd cheers.
Then there's the scramble for the candy.
The Bohart Museum is the home of some 8 million insect specimens, plus a live "petting zoo" (Madagascar hissing cockroaches, walking sticks, tarantulas and praying mantids) and an insect-themed gift shop. It's directed by Lynn Kimsey, UC Davis professor of entomology. Those who join the Bohart Museum Society look forward to their invitation to the annual pre-Halloween party, which this year featured a parasitoid theme. (See Oct. 29 Bug Squad blog).
How much of a smash hit was the piñata? See the images below and the YouTube video.
The Bohart Museum Society hosted the Bohart Museum of Entomology's 24th annual pre-Halloween party on Saturday, Oct. 27 at the University of California, Davis, billing it as “They Come From Within" and promising a “haunting night full of frights and delights."
You can thank the emerald cockroach wasp or jewel wasp (Ampulex compressa), an entomophagous parasite, for that! It is known for its unusual reproductive behavior, in which it stings a cockroach and then uses it as a host for its larvae, eating it alive.
That was the critter depicted on the invitation.
UC Davis entomology undergraduate student and talented artist Karissa Merritt created the much-applauded, wasp-inspired invitation. "For this year's Bohart Halloween party invite, I set out to create an original--fake--movie poster, inspired by old B-movies such as 'Them' and 'Invasion of the Saucer Men,'" she explained. "I really wanted the invitations to grab people's attention with the bright colors, and grotesque horror as a giant jewel wasp--based on Ampulex compressa--emerges from a living man's chest."
It did. It also grabbed the attention of UC Davis entomology doctoral candidate Charlotte Herbert Alberts, who studies Asilidae (Assassin flies) with her major professor, Lynn Kimsey, director of the Bohart Museum and professor of entomology. "I made my costume to honor Karissa's incredible drawing of the invitation," said Charlotte, who anticipates receiving her Ph.D in 2020. Her husband, George, dressed as Dracula. Their Brittany Spaniel, Westley, declined to wear a dinosaur costume and came as himself.
At the entrance, assorted mustaches and masks commanded a table. A sign urged people to "write a name tag, yet disguise yourself if you aren't in costume." (With the addition: "I know it doesn't make sense; just humor us.")
Among those coming as themselves were entomologist Jeff Smith, who curates the butterfly and moth collection; his wife, Cathy; and Bohart associate and naturalist-photographer Greg Kareofelas.
Senior museum scientist Steve Heydon wore an orange jumpsuit lettered with "Department of Corrections" while his wife, Anita, came dressed as a police officer, complete with badge and handcuffs.
Forensic entomologist Robert "Bob" Kimsey, husband of Lynn Kimsey, donned his traditional ghillie suit.
Bohart Museum director Lynn Kimsey cut a 72nd anniversary cake, a red-velvet, chocolate-frosted cake decorated with--what else?--bugs! After all, the Bohart Museum houses some 8 million specimens, plus a live "petting zoo" of Madagascar hissing cockroaches, walking sticks, tarantulas and praying mantids, as well an insect-themed gift shop.
Meanwhile evolutionary ecologist Scott Carroll, at 6'11", towered over everyone. "I can pick him out in a crowd," quipped his wife, entomologist Jenella Loye.
(See tomorrow's Bug Squad blog for more Halloween images, including the pinata breaking game. The pinata? A replica of a monarch chrysalis.)
Bohart associates sang "Happy Birthday" and cheered when he blew out a candle on the dessert plate.
For the occasion, doctoral student Charlotte Herbert Alberts, who studies with Lynn Kimsey, director of the Bohart Museum and professor of entomology at UC Davis, drew two longhorned bees on his birthday card envelope--the bees replaced the "b's" in his first name. Tabatha Yang, education and outreach coordinator at the Bohart Museum, coordinated the event.
Thorp actually celebrated his birthday while he was teaching Aug. 18-28 at The Bee Course, sponsored annually by the American Museum of Natural History, New York at its Southwest Research Station, Portal, Ariz. The nine-day intensive workshop draws conservation biologists, pollination ecologists, and other biologists who seek greater knowledge of the systematics and biology of bees.
He is the co-author of Bumble Bees of California: An Identification Guide (2014, Princeton University Press) and California Bees and Blooms: A Guide for Gardeners and Naturalists (2014, Heyday Books). both available in the Bohart Museum of Entomology's gift shop.
Robbin received his bachelor and master's degrees in zoology from the University of Michigan, Ann Arbor, and his doctorate degree in entomology from the University of California, Berkeley. He served on the faculty of the UC Davis Department of Entomology (now the Department of Entomology and Nematology) from 1964 to 1994.
During his long and productive career, Thorp conducted research on pollination of crops pollinated by honey bees, especially almonds. His research also included the use of other bee species in crop pollination, the roles of native bees in pollination of flowers in natural ecosystems such as vernal pools, and the ecology and systematics of native bees. He taught courses at UC Davis in General Entomology, Natural History of Insects, Insect Classification, Field Entomology, California Insect Diversity, and Pollination Ecology, and has given scores of public presentations.
Thorp is a fellow of the California Academy of Sciences, San Francisco (since 1986). Among his many awards: the distinguished team award (shared with Eric Mussen, Neal Williams, Brian Johnson and Lynn Kimsey of the UC Davis Department of Entomology and Nematology) in 2013 from the Pacific Branch of the Entomological Society of America for their collaborative work specializing in honey bees, wild bees and pollination issues through research, education and outreach. Their service to UC Davis at that time spanned 116 years.
Although Thorp retired in 1994, he continues to be active. For many years after his retirement, he researched ecology, systematics, biodiversity, and conservation of bees including pollen specialist bees in vernal pool ecosystems, as well as the role of native bees in crop pollination, the role of urban gardens as bee habitat, and declines in native bumble bee populations. He maintains an office at the Harry H. Laidlaw Jr. Honey Bee Research Facility at UC Davis where he continues his public service. That includes identifying bees for his colleagues. He recently served as a "bee" advisor for Leslie Saul-Gershenz, who holds a doctorate in entomology from UC Davis (2017) and published her first piece in the Proceedings for the Natural Academy of Sciences (PNAS) on “Deceptive Signals and Behaviors of a Cleptoparasitic Beetle Show Local Adaptation to Different Host Bee Species.”
Robbin Thorp is truly a dedicated entomologist who does the University of California proud!
