The Bohart Museum, home of nearly eight million insect specimens collected worldwide, will be one of the 13 museums or collections open on Saturday, Feb. 15 during the ninth annual UC Davis Biodiversity Museum Day.

Directed by Lynn Kimsey, professor of entomology at UC Davis, the Bohart Museum is located in Room 1124 of the Academic Surge Building on Crocker Lane. Scientists at the insect museum will greet visitors, show specimens, and answer questions from 9 a.m. to noon. The insect museum is also the home of a live "petting zoo," including Madagascar hissing cockroaches, walking sticks, and tarantulas. Its year-around gift shop is stocked insect-themed t-shirts and jewelry, books, posters, and collecting equipment.

Here's what's on tap for the campuswide Biodiversity Museum Day, a science-based day that's free and family friendly. The event drew 4000 visitors last year.

The schedule:

• The Botanical Conservatory, the Greenhouses along Kleiber Hall Drive, will be open from 9 a.m. to 4 p.m.

The following five will be open from 9 a.m. to 1 p.m.:

• Arboretum and Public Garden, Shields Oak Grove, alongside the Vet School,  Garrod Drive on campus
• Bohart Museum of Entomology, Room 1124 and Main Hall of the Academic Surge Building, Crocker Lane
• California Raptor Center, 340 Equine Lane, off Old Davis Road
• Museum of Wildlife and Fish Biology, Room 1394 and Mail Hall,  Academic Surge Building, Crocker Lane
• Paleontology Collection, Earth and Physical Sciences Building, 434 LaRue Road

Two collections will be open from 10 a.m. to 2 p.m.:

• Phaff Yeast Culture Collection, Robert Mondavi Institute of Wine and Food Science, 392 Old Davis Road, on campus
• Viticulture and Enology Culture Collection, Robert Mondavi Institute of Wine and Food Science, 392 Old Davis Road, on campus

These five will be open from noon to 4 p.m.:

• Anthropology Museum, 328 Young Hall and grounds
• Center for Plant Diversity, Sciences Laboratory Building, off Kleiber Hall Drive
• Häagen-Dazs Honey Bee Haven, Bee Biology Road, off Hopkins Road (take West Hutchison Drive to Hopkins)
• Nematode Collection, Sciences Laboratory Building, off Kleiber Hall Drive
• Marine Invertebrate Collection, Sciences Laboratory Building, off Kleiber Hall Drive

New this year will be public talks from noon to 1 p.m. in 194 Young Hall. The slate of speakers:

• Art Shapiro, distinguished professor of evolution and ecology, will discuss “Are Our Butterflies in Trouble?” (“Yes, they mostly are in trouble,” he says. He will discuss “How do we know and why?”)
• Gabrielle Nevitt, professor of animal behavior (on leave), will speak on “How Do Sub-Antarctic Seabirds Find their Food in the Vast Ocean?” (“They follow their nose," she says, "and sometimes it gets them into trouble.”)
• Melanie Truan, research ecologist, UC Davis Museum of Wildlife and Fish Biology, will cover “Biodiversity Studies at the UC Davis Wildlife Museum.” Biodiversity studies, she says, “can tell us a lot about the world and how it is functioning. This is especially important today where the influence of Homo sapiens is having profound impacts on the planet and its inhabitants.” She will touch on some of the ways that the UC Davis Museum of Wildlife and Fish Biology incorporates biodiversity into its research. 

Each scientist will present a 15-minute talk, with a question-and-answer session to follow.

All participating museums and collections have active education and outreach programs, said Biodiversity Museum Day coordinator Tabatha Yang, education and outreach coordinator for the Bohart Museum,  but the collections are not always accessible to the public.   Maps, signs and guides will be available at all the collections, and also online at http://biodiversitymuseumday.edu, and on social media, including Facebook and Twitter, @BioDivDay.

As you meander from site to site, pay close attention to the t-shirts the scientists/volunteers are wearing; pay attention for two reasons:

1. The t-shirt design, the work of entomologist/artist Ivana Li, shows a double-decker bus filled with organisms you'll see during the daylong science-based event. “I wanted a shirt that featured all the collections with a unifying element that felt very UC Davis,” said Li, a UC Davis biology lab manager. “I considered a cow initially, but once I sketched out the double-decker bus, it was the clear choice."
   
   
2. In keeping with diversity, the name tags will indicate the languages or multiple languages each volunteer speaks.  In addition to English and Spanish, they may include French, German, Portuguese, Mandarin, Indonesian and Swahili.

"The double-decker bus is filled with an organism from each type of collection--super cute," commented Biodiversity Museum Day coordinator Tabatha Yang, education and outreach coordinator of the Bohhart Museum of Entomology. "The shirts were generously donated by Ink Monkey, a local Davis printing company, making them an in-kind sponsor."

“To the shirts we are adding sticker badges that indicate if the scientist can speak languages other than English,” Yang said.  “There are many ways to make science more accessible and so these simple language badges are just another way to communicate and to celebrate the globalness of our science collections and of UC Davis.  Emma Cluff (Bohart associate) and I got the idea last year after attending a California Association of Museum conference that brought up a lot of issues about diversity ( the human kind) in museums.”

Kyria Boundy-Mills, curator of the Phaff Yeast Culture Collection, Food Science and Technology, quipped that her lab "has many cultures—both yeast cultures and human cultures.” Many in her lab are multilingual. For example, Blake Li speaks Mandarin and Irna Sitepu, Indonesian.

In the Jason Bond lab, UC Davis Department of Entomology and Nematology, doctoral candidate Rebecca Godwin speaks  Spanish and Swahili as well as English.

The  UC Davis Biodiversity Museum Day, always held the Saturday of Presidents' Day weekend, is billed as a “free, educational event for the community where visitors get to meet and talk with UC Davis scientists from undergraduate students to staff to emeritus professors and see amazing objects and organisms from the world around us." The schedule is online at http://biodiversitymuseumday.ucdavis.edu/schedule.html.  Last year's event drew more than 4000 visitors.

Bohart Museum of Entomology, 9 a.m. to 1 p.m.
TheBohart Museum of Entomology, located in Room 1124 of the Academic Surge Building onCrocker Lane, is the home of a global collection of nearly 8 million insect specimens. Insect scientists will meet with the public to help them explore insects and spiders (arachnids). Highlights will include the 500,000-specimen butterfly/moth collection, curated by entomologist Jeff Smith. The Bohart maintains a live “petting zoo,” comprised of Madagascar hissing cockroaches, walking sticks and tarantulas. Also, the UC Davis Library set up a Mary Foley Benson exhibit in the Academic Surge hallway. It will be up ponly for the month of February. "The library, is, of course full of special collections including very important research materials on bees and on nematodes," noted Tabatha Yang, the Bohart education and outreach coordinator.

California Raptor Center, 9 a.m. to 1 p.m.
Visitors to the The California Raptor Center, located at 1340 Equine Lane, Davis, just off Old Davis Road,  will see a living collection of non-releasable raptors. The center's educational ambassador birds will be out "on the glove," so visitors can get a close view of the birds of prey, and talk to the volunteers. Julie Cotton, volunteer and outreach coordinator, said visitors will see "on the glove" Swainson's hawks, a white-tailed kite, barn owl, great-horned owls and a eregrine falcon. Viewable in their exhibits will be golden eagles, American kestrels, turkey vultures, prairie falcon and Western screech owls.

Museum of Wildlife and Fish Biology, 9 a.m. to 1 p.m
The Museum of Wildlife and Fish Biology, located in Room 1394 of the Academic Surge Building, Crocker Lane (off LaRue Road)  will feature an action packed morning with displays highlighting carnivores, bats, reptiles and fish, said director Andrew Engilis Jr.  Visitors will see specimen preparation demonstrations. Also planned is a kids' craft table.

Paleontology Collection, 9 a.m. to 1 p.m.
Visitors at the Paleontology Collection, located in the Earth and Physical Sciences Building, 434 LaRue Road, can view fossil specimens dating from as old as 550 million years ago to more recent animal skeletons. Paleontology graduate students in invertebrate and vertebrate paleontology will answer questions and provide interesting factoids.

Phaff Yeast Culture Collection and Viticulture and Enology Culture Collection, 10 a.m. to 2 p.m.
The Phaff Yeast Culture Collection in the Department of Food Science, and the Wine Yeast and Bacteria collection in the Department of Viticulture and Enology, are jointly hosting exhibits and tours. They are located at the Robert Mondavi Institute Teaching Winery and Brewery Building, 392 Old Davis Road, on campus. Visitors to the yeast collection exhibits can taste kombucha and Vegemite, smell lots of different species of yeast, look at yeast and bacteria cells under the microscope, learn about the history of yeast research at UC Davis, and hear about the latest discoveries coming out of the UC Davis yeast collections, says Kyria Boundy-Mills, curator of the Phaff Yeast Culture Collection, Food Science and Technology.

Anthropology Museum, noon to 4 p.m.
Visitors to the Department of Anthropology Museum, located in 328 Young Hall, will see collections of archaeological, ethnographic, biological and archival materials. They will "experience our cultural diversity through art pieces from around the world, our complex evolutionary history through primate skeletons and fossil hominin casts, or how archaeologists at UC Davis work across the globe to understand past cultural diversity through the artifacts people leave behind," said Professor Christyann Darwent of the Department of Anthropology. "There will also be an opportunity for visitors to learn to make tools from obsidian stone and to throw a spear with an atlatl."

The Botanical Conservatory, 9 a.m. to 4 p.m.
"We again expect our cacao tree to be loaded with ripe fruit for display amongst the plethora of plant we'll be displaying!" says collections manager Ernesto Sandoval. "We'll also be showcasing our very well established pond that made a splash last year and newly added small epiphyte tree along with three towering Titan Arums in leaf!  if the outdoor weather is good, Visitors will be encouraged to take a walk over to the nearby Joe and Emma Lin Biological Orchard and Gardens and bask in the biodiversity of these sizable plots of Biodiversity and the neatly pruned fruit tree orchard." The Botanical Conservatory is located on Kleiber Hall Drive.

Center for Plant Diversity Herbarium, noon to 4 p.m.
Visitors to the Center for Plant Diversity Herbarium, located in Room 1026 of the Sciences Laboratory Building, central campus (off Kleiber Hall Drive),  can tour the collection area, see plant pressing and mounting demonstrations, “pet our plant zoo” (a table showcasing the diversity of plants, including mosses, pine cones, ferns and flowering plants); look and plants under a microscope, and view oak exhibit. The children's activity? Making herbarium specimens, says curator Ellen Dean.

Häagen-Dazs Honey Bee Haven, noon to 4 p.m.
Visitors to the Häagen-Dazs Honey Bee Haven, a half-acre bee demonstration garden located next to the Harry H. Laidlaw Jr. Honey Bee Research Facility, Bee Biology Road, can learn about bees and see the plants they frequent, said manager Christine Casey. Guests will learn how to identify bees. They can also use a bee vacuum to  catch, observe and release bees. A six-foot long sculpture of a worker bee by artist Donna Billick of Davis anchors the haven.

Nematode Collection, noon to 4 p.m.
The nematode collection will open from noon to 4 p.m. in the Science Laboratory Building, off Kleiber Hall Drive. It will feature both live and slide-mounted nematodes, as well as jars of larger parasites. Nematodes, also called worms, are described as “elongated cylindrical worms parasitic in animals or plants or free-living in soil or water. They exist in almost every known environment.”

Marine Invertebrate Collection, noon to 4 p.m.
The Marine Invertebrate Collection in the Science Laboratory Building, off Kleiber Hall Drive, will have  touch tanks, preserved specimens, and some displays showing aspects of marine ecology and evolution. There will also be a seashell activity for kids, said Ivana Li. "In our touch tanks, we'll likely have sea stars and sea urchins. We are showing all the different geographical locations from which they were collected. This means that people can match up where specimens like our slipper lobster or salp came from. Other displays that we will have are on how to distinguish true crabs from other animals, and a display on seaweed ecology." 

The sponsors made it all possible to have this event free to the public, Yang said. Ink Monkey provided 300 t-shirts for the volunteers, and Marrone Bio Innovations and Novozymes are also major supporters. Other supporters include the UC Davis Honey and Pollination Center, UC Davis Library, White Labs Inc., Margaret Berendsen, Fletchers Real Estate, Peter Lash and Dan Potter.

How many different bumble bee species have you seen or photographed this year?

Have you seen the black-tailed bumble bee, Bombus melanopygus? It's the earliest to emerge in this area.

We photographed several B. melanopygus on Jan. 25 near downtown Benicia.  Three were foraging on rosemary and one on a rose.

B. melanopygus is native to western North America and found from California to British Columbia and as far east as Idaho, it forages on manzanitas, wild lilacs, wild buckwheats, lupines, penstemons, clovers, and sages, among others.

Our little Bombus posse--Allan Jones, Gary Zamzow and Kim Chacon, all of Yolo County, and yours truly of Solano County--annually  compete to find and photograph the first bumble bee of the year. As earlier mentioned,  Jones won the 2020 contest--he photographed a B. melanopygus on Jan. 6 in the UC Davis Arboretum and Public Garden. No bumble bees are harmed in this contest. We don't poke 'em, prod 'em or pin 'em. We just take their picture, or rather, we capture their images.

The contest began in 2012 with our mentor, Robbin Thorp (1933-2019), distinguished emeritus professor of entomology, UC Davis Department of Entomology and Nematology. To memorialize him, the contest will now be known as  Robbin Thorp Memorial Bumble Bee Contest and will sponsored by the Bohart Museum of Entomology, where the professor spent much of his time.

Thorp, a member of the UC Davis entomology faculty for 30 years (1964-1994), achieved emeritus status in 1994 but continued to engage in research, teaching and public service until a few weeks before his death. In 2014, during his retirement, he co-authored two books, Bumble Bees of North America: An Identification Guide California Bees and Blooms: A Guide for Gardeners and Naturalists. He co-taught The Bee Course from 2002 to 2019. This is an intensive nine-day workshop affiliated with the American Museum of Natural History and held annually at the Southwestern Research Station, Portal, Ariz. It's geared for conservation biologists, pollination ecologists, and other biologists who want to gain greater knowledge of the systematics and biology of bees.

The good professor was always concerned about the declining bumble bees, especially Franklin's bumble bee, found only in a small range in Southern Oregon and Northern California. He was a global authority on bumble bees and sounded the alarm to protect bumble bees, including this one. Lynn Kimsey, director of the Bohart Museum of Entomology and a UC Davis professor, fears it is extinct. No one has seen it since Thorp spotted it in 2006. (See Bug Squad)

Meanwhile, keep an eye out for bumble bees, and do what you can to protect them (plant flowers that they prefer and don't use pesticides). Robbin Thorp would have liked that.

You've probably seen them hovering over flowers, which is why syprhids are commonly called "hover flies" or "flower flies."

Enter Andrew Young.

He's a UC Davis postdoctoral researcher with the Department of California Food and Agriculture (CDFA) and he researches syrphids.

Young, who specializes in Diptera taxonomy and phylogenetics at CDFA, will present a seminar to the UC Davis Department of Entomology and Nematology on "The Natural History of Syrphidae: from Pollinators to Parasitoids" at 4:10 p.m., Wednesday, Feb. 5 in 122 Briggs Hall, off Kleiber Hall Drive.

"Syrphidae (Dlptera) is a species-rich family of true fly, with over 6200 described species worldwide," he says in his abstract. "Often known as flower flies or hover flies, syrphlds are likely the most significant group of pollinators outside of the bees--especially in Arctic climates. While research into their pollination-related behavior is still nascent, other aspects of flower fly biology have been relatively well-studied."

"Adults of many species are well-known for their impressive mimicry of stinging Hymenoptera, and known larvae display a degree of habitat diversity that is unusually broad for a single family of Diptera. Many larvae are predators on soft-bodied insects such as aphids, and therefore, show potential for crop-pest management, while others are aquatic filter-feeders that may have value in waste-management applications." (See UC Integrated Pest Management Program website on syrphids; in their larval stage, they feed on aphids.)

Young says he will give an overview of the current understanding of flower fly phylogeny, followed by an exploration of the varied many adult and larval natural histories known to the group. He will emphasize "many of the little-known larval life histories that are still actively being discovered by dedicated field researchers. I will conclude by briefly discussing some of my past, present and future flower fly research."

Young studied Syrphidae in the lab of Stephen Marshall, professor of entomology at the University of Guelph, Ontario, Canada. Marshall and Young are among the six co-authors of Field Guide to the Flower Flies of Northeastern North America" (Princeton University Press, 2019), a book described as "a groundbreaking guide to flower flies in North America."

From the Princeton University Press website: "Flower flies are, along with bees, our most important pollinators. Found in a varied range of habitats, from backyard gardens to aquatic ecosystems, these flies are often overlooked because many of their species mimic bees or wasps. Despite this, many species are distinctive and even subtly differentiated species can be accurately identified." The guide includes more than 3,000 color photographs and 400 maps, covering all 416 species of flower flies that occur north of Tennessee and east of the Dakotas, including the high Arctic and Greenland. Each species account provides information on size, identification, abundance, and flight time, along with notes on behavior, classification, hybridization, habitats, larvae, and more."

Lynn Kimsey, director of the Bohart Museum of Entomology and professor of entomology at UC Davis, is the seminar host. Community ecologist Rachel Vannette, assistant professor, coordinates the weekly seminars.

Upcoming seminars for the winter quarter (See speaker list) are at 4:10 p.m. on Wednesday in 122 Briggs Hall.
