It will not be a day--it will be a month, the month of February.
It will not be a walk-around event--it will be virtual.
Traditionally billed as a “free, educational event for the community where visitors get to meet and talk with UC Davis scientists "and see amazing objects and organisms from the world around us,” it's a science-based event showcasing the diversity of life, according to Biodiversity Museum Day coordinator Tabatha Yang, education and outreach coordinator for the Bohart Museum of Entomology.
Over the last nine years, it took place the Saturday of Presidents' Day weekend. Last year more than 4000 attended.
Information on the event is being posted on the UC Davis Biodiversity Museum Day website as plans unfold. The 12 museums or collections participating in the virtual program this year via Zoom webinars, Facebook programs and YouTube will be:
- Anthropology Museum
- Arboretum and Public Garden
- Bohart Museum of Entomology
- Botanical Conservatory
- California Raptor Center
- Center for Plant Diversity
- Häagen-Dazs Honey Bee Haven
- Nematode Collection
- Marine Invertebrate Collection
- Museum of Wildlife and Fish Biology
- Paleontology Collection
- Phaff Yeast Culture Collection
Live talks will encompass such topics as heliconius butterflies, bees and gardens, orchid bees, plants in the Botanical Conservatory, Asian giant hornets (aka murder hornets), ants, yeasts, mammal specimen preparations and raptors.
Pre-recorded programs will cover bee diversity, millipedes, herbariums and marine life, as well as how to make a bee condo and how to prepare insects (spread the wings of butterflies and moths) for display, among other subjects.
All participating museums and collections have active education and outreach programs, Yang said, but the collections are not always accessible to the public. More information is pending on the website at http://biodiversitymuseumday.edu, and on social media, including Facebook and Twitter, @BioDivDay.
The UC Biodiversity Museum Day/Month program is participating in Crowdfund UC Davis "where alumni, students, parents and friends can make donations to support innovative projects that propel student engagement, new research discoveries, and efforts to expand UC Davis impact on California and the world." The funding program will continue through the end of February.

Cooperative Extension agricultural specialist Ian Grettenberger, assistant professor, UC Davis Department of Entomology and Nematology, and his graduate student, Madison "Madi" Hendrick, will discuss the crops, the pests, and the natural enemies or beneficials at a virtual Facebook live session from 11 a.m. to noon, Thursday, Oct 22.
The event, "The Good and the Bad: Insects and Other Arthropods in Agriculture, with a Focus on California Rice and Alfalfa," will be live-streamed on the UC Davis Bohart Museum of Entomology's Facebook page. (Link to Facebook live here). Grettenberger and Hendrick will present short talks and then field questions. No personal Facebook account is required to join the session, which is free and open to the public.
"This is all about the arthropods, both the pests and beneficials that they study in the rice and alfalfa fields," said Tabatha Yang, education and outreach coordinator for the Bohart Museum of Entomology. "Most of the focus is on insects, but tadpole shrimp in rice fields also will be discussed." A virtual family craft activity is also planned.
"I will be discussing some of the insect (or arthropod) problems faced by growers of rice in California and some of the challenges in managing them, Grettenberger said. "In rice, some of the key arthropod pests are tadpole shrimp, which can turn what would have been a lush stand if rice into a poor stand with a lot of floating seedlings. Meanwhile, later in the year, armyworm caterpillars, the larvae of a moth, can chew on rice leaves and destroy plants. I'll discuss some of the ongoing work to better understand and manage these pests."
Grettenberg's fields of expertise include field and vegetable crops; integrated pest management; applied insect ecology, and biological control of pests. (See Spotlight on Ian Grettenberger.) Among his current grants:
- Protection of rice from invertebrate pests
- Insecticide resistant alfalfa weevils in the western United States: Quantifying the scope of resistance and implementing a plan to manage the threat
- Management of key cotton arthropod pests with insecticides and acaricides, a proactive approach to prepare for the invasion of the tomato leafminer (Tuta absoluta) into California
- Detection, biology and control of the exotic Swede midge (Contarinia nasturtii) for California cole crops
- Management of the western spotted and striped cucumber beetle in melon production
- Biological control of the bagrada bug
- Insecticide resistance monitoring and evaluation of efficacy of current chemical tactics for managing aphids and thrips in lettuce
What sparked his interest in entomology? "I had biologist parents, and was drawn into entomology at a pretty young age," Grettenberger said. "I spent plenty of time looking in flowers and turning over logs looking for insects. Once I started thinking about going to graduate school for entomology, I decided to focus on the intersection of agricultural entomology and insect ecology. I wanted to work on applied issues in entomology."
Hendrick, a second-year graduate student in the Grettenberger lab, received her bachelor's degree in iInternational studies at North Carolina State University, and also spent a semester at Nagoya University in Japan (she minored in Japanese).
"I got my start in entomology completely by chance!," Hendrick related. "I needed a science credit and happened to pick a class called 'Insects and People.”' That class really helped me to reframe the way I thought about insects and appreciate what interesting little critters they are. Through that class, I was also able to get a job as an undergraduate assistant in an entomology lab. I worked in a specialty crops lab, where I developed interests in integrated pest management and invasive species. I now study insecticide resistance in the alfalfa weevil, and I'm excited to share what I've learned through this outreach event!"
Grettenberger, Yolo County Farm Advisor Rachael Freeman Long and Madi Hendrick recently wrote a piece in the UC Agricultural and Natural Resources (UC ANR) blog, Alfalfa and Forage News, "A (Virtual )Update on Worms, Weevils an Aphids in Alfalfa."
"This year, the Kearney Research and Extension Center Alfalfa and Forage Field Day went virtual," Grettenberger wrote. "Attendees did not get the chance to look out over lush fields of alfalfa or towering plantings of sorghum, but they get did an update on ongoing work in alfalfa and other forages. Our team put together a rapid-fire video to discuss what are typically the key insect pests in California alfalfa: summer worms, alfalfa weevils, and aphids."
The summer worms in alfalfa include the summer worms: Western yellowstriped armyworm, beet armyworm and alfalfa caterpillar. Another key pest is the alfalfa weevil. The trio also discussed aphids and their natural enemies, including lady beetles, aka ladybugs).
Pests of rice include armyworms, aster leafhoppers, crayfish, rice leafminers, rice seed midges, rice water weevils and tadpole shrimp.
The Bohart Museum, directed by Lynn Kimsey, UC Davis professor of entomology, is located in Room 1124 of the Academic Surge Building on Crocker Lane, UC Davis campus, but is temporarily closed. The museum houses nearly eight million insect specimens; a live "petting zoo" of Madagascar hissing cockroaches, walking sticks and taranatulas; and a gift shop stocked with insect-themed T-shirts, books, posters, jewelry, candy and insect-collecting equipment.

The Bohart Museum will live-stream the free open house on Facebook. Entomologist Jeff Smith, who curates the 500,000 Lepidoptera (butterflies and moths) collection, will show specimens and answer questions.
Due to the COVID-19 pandemic, this is the Bohart Museum's first-ever Virtual Moth Open House.
“We started holding a moth-themed open house near Mother's Day in May, because people who are enthusiasts for moths are called moth-ers,” said Tabatha Yang, education and outreach coordinator for the Bohart Museum. “We then switched our programming to align with National Moth Week. This year's Moth Week is July 18-26. The annual event is celebrated throughout the world with private and public events.
Bohart Museum officials are preparing videos on black-lighting and how to spread and pin moths.
During the Facebook Live program, viewers can type in their questions on moths.
Smith is expected to answer questions such as:
- What is the largest moth?
- How do butterflies and moths differ?
- What is so unique about moths?
- Why should we be concerned with moth diversity?
Smith received a 2015 Friend of the College Award from the UC Davis College of Agricultural and Environmental Sciences for saving the museum some $160,000 over a 27-year period through his volunteer service.
Kimsey, who has directed the museum since 1989, remembers when Smith joined the museum. “When Jeff was working for Univar Environmental Services, a 35-year career until his retirement in 2013, he would spend some of his vacation days at the museum. Over the years Jeff took over more and more of the curation of the butterfly and moth collection. He took home literally thousands of field pinned specimens and spread their wings at home, bringing them back to the museum perfectly mounted. To date he has spread the wings on more than 200,000 butterflies and moths. This translates into something like 33,000 hours of work!” The numbers have since increased.
“About a decade ago, Jeff began helping us by assembling specimen drawers from kits that we purchased,” Kimsey related. “This substantially lowered our curatorial costs, from $50/drawer to $16/drawer. We use several hundred drawers a year to accommodate donated specimens, research vouchers and specimens resulting from research grants and inventories. More recently, he's been accumulating scrap lumber and making the drawers from scratch at no cost to us. Overall, he has made more than 2000 drawers. Additionally, he makes smaller specimen boxes with the leftover scrap wood, which are used by students taking various field courses in the department. We simply could not curate the collection without his contributions.”
Kimsey praised Smith for completely reorganizing the butterfly and moth collection. “It's no small feat to rearrange this many specimens, housed in roughly one thousand drawers,” she said. “Many thousands of the specimens needed to be identified, and the taxonomy required extensive updating and reorganization.”
The Bohart Museum, located in Room 1124 of the Academic Surge Building, Crocker Lane, UC Davis campus, houses a global collection of nearly eight million specimens. It is also the home of the seventh largest insect collection in North America, and the California Insect Survey, a storehouse of the insect biodiversity. Noted entomologist Richard M. Bohart (1913-2007) founded the museum.
Bohart Museum is the home of a “live” petting zoo featuring Madagascar hissing cockroaches, walking sticks and tarantulas, and a gift shop, stocked with T-shirts, sweatshirts, books, jewelry, posters, insect-collecting equipment and insect-themed candy.
And what's the canceled 105th annual UC Davis Picnic without virtual insects?
The Department of Entomology and Nematology annually hosts dozens of insect-themed Picnic Day events at Briggs Hall and at the Bohart Museum of Entomology. But this year, the insects went virtual due to the coronavirus pandemic precautions.
The campuswide Picnic Day Committee hosted a virtual tour of some of the planned events, and posted this link: https://picnicday.ucdavis.edu/virtual/
The spotlight paused on the Bohart Museum, which houses nearly eight million insect specimens; the seventh largest insect collection in North America; the California Insect Survey, a storehouse of the insect biodiversity; and a live “petting zoo” comprised of Madagascar hissing cockroaches, walking sticks, tarantulas and the like. It also is the home of a gift shop, stocked with T-shirts, sweatshirts, books, jewelry, posters, insect-collecting equipment and insect-themed candy.
Directed by UC Davis entomology professor Lynn Kimsey for 30 years, the museum is named for noted entomologist Richard Bohart (1913-2007). The Bohart team includes senior museum scientist Steve Heydon; Tabatha Yang, education and outreach coordinator; and entomologist Jeff Smith, who curates the Lepidoptera (butterflies and moths section).
If you browse the Bohart Museum site, you'll find fact sheets about insects, written by Professor Kimsey.
But if you want to see the Bohart Museum's virtual tours, be sure to watch these videos:
- Director Lynn Kimsey giving a Bohart Museum introduction
- Tabatha Yang, education and outreach coordinator, presenting an arthropod virtual tour
- Diane Ullman, professor of entomology and former chair of the department, presenting a view of the Lepidodpera section.
Also on the UC Davis Virtual Picnic Day site, you'll learn “How to Make an Insect Collection," thanks to project coordinator James R. Carey, distinguished professor, UC Davis Department of Entomology and Nematology; and "Can Plants Talk to Each Other?" a TED-Ed Talk featuring the work of ecologist Rick Karban, professor, UC Davis Department of Entomology and Nematology.
"Female tsetse flies carry their young in an adapted uterus for the entirety of their immature development and provide their complete nutritional requirements via the synthesis and secretion of a milk like substance," he says. PBS featured his work in its Deep Look video, “A Tsetse Fly Births One Enormous Milk-Fed Baby,” released Jan. 28, 2020. (See its accompanying news story.)
PBS also collaborated with the Attardo lab and the Chris Barker lab, UC Davis School of Veterinary Medicine, for a PBS Deep Look video on Aedes aegypti, the mosquito that transmits dengue fever and Zika. The eggs are hardy; "they can dry out, but remain alive for months, waiting for a little water so they can hatch into squiggly larvae," according to the introduction. Watch the video, "This Dangerous Mosquito Lays Her Armored Eggs--in Your House."
In the meantime, the UC Davis Picnic Day leaders are gearing up for the 106th annual, set for April 17, 2021. What's a picnic without insects?
The Bohart Museum of Entomology is hosting its annual "Parasitoid Palooza" from 1 to 4 p.m., Saturday, Oct.19.
The event, free and family friendly, takes place in Room 1125 of the Academic Surge Building on Crocker Lane, UC Davis campus.
"An insect parasitoid is a species whose immatures live off of an insect host, often eating it from the inside out," said Tabatha Yang, education and outreach coordinator of the Bohart Museum. "It is part of their life cycle and the host generally dies."
Senior museum scientist Steve Heydon, who researches Pteromalids or jewel wasps, will present his work and answer questions. Graduate student Socrates Letana will also field parasite questions from the crowd.
There are some 3,450 described species of Pteromalids, found throughout the world and in virtually all habitats. Many are important as biological control agents.
Also planned at the open house:
- A family craft activity, to be announced
- Sampling of Chirp Chips, from the Bohart Museum's recent entomophagy open house
- Display of orange and black Harlequin beetles (just in time for Halloween) from Jasmin Ramirez Bonilla of the Ian Grettenberger lab, UC Davis Department of Entomology and Nematology
- Display of pumpkin-eating pests--cucumber beetles--which can be a pest on squashes, cucumbers and other members of the cucurbits family.
The Bohart Museum, directed by Lynn Kimsey, professor of entomology at UC Davis, houses a global collection of nearly eight million specimens. It is also the home of the seventh largest insect collection in North America, and the California Insect Survey, a storehouse of the insect biodiversity.
Special attractions include a “live” petting zoo, featuring Madagascar hissing cockroaches, walking sticks, praying mantids and tarantulas. Visitors are invited to hold some of the insects and photograph them. The museum's gift shop, open year around, includes T-shirts, sweatshirts, books, jewelry, posters, insect-collecting equipment and insect-themed candy.
The Bohart Museum holds special open houses throughout the academic year. Its regular hours are from 9 a.m. to noon and 1 to 5 p.m. Mondays through Thursdays. The museum is closed to the public on Fridays, Saturdays and Sundays and on major holidays. Admission is free.
