Graduate students from the Jason Bond laboratory will showcase spiders, scorpions, centipedes and millipedes, while the Lynn Kimsey lab at the Bohart Museum will display specimens of the Asian giant hornet, Vespa mandarinia (nicknamed "the murder hornet" by the news media); and specimens of the state insect, the California dogface butterfly, Zerene eurydice, and its host plant, California false indigo, Amorpha californica.

Bond is the Evert and Marion Schlinger Endowed Chair in Insect Systematics, UC Davis Department of Entomology and Nematology, and associate dean, College of Agricultural and Environmental Sciences. Kimsey, a UC Davis distinguished professor of entomology, directs the Bohart Museum.

"The arachnid/myriapod section of Biodiversity Museum Day will consist of some live specimens--a tarantula, trapdoor spider, scorpion, and some millipedes, and ethanol preserved specimens of arachnids/myriapods that are pretty common and/or well-known, and a small interactive station where people will be able to use props that mimic an insect flying into a web and learn more about the sensory structures that spiders have to detect those vibration," said doctoral candidate Lacie Newton of the Bond lab, coordinator of the exhibit.

The Bohart section will feature Professor Kimsey sharing her expertise on the Asian giant hornet, and Professor Fran Keller of Folsom Lake College, a Bohart scientist and UC Davis doctoral alumnus will join Bohart associate Greg Kareofelas, naturalist and photographer, in discussing the California dogface butterfly and its host plant.

Admission and parking are free, but visitors must adhere to the COVID-19 Campus Ready guidelines. Masks will be required in accordance with campus policies, organizers said. Visitors can also sign up at the Conference Center for limited tours. The collections or museums offering tours:

• The Bohart Museum of Entomology, located in Room 1124 of the Academic Surge Building, Crocker Lane, has scheduled tours at noon, 1 and 2. The Bohart houses a global collection of eight million insect specimens, and also a live "petting zoo" and gift shop. "People will sign up at the Convention Center and be chaperoned over approximately 15 minutes before the hour to the attend their tour," said Tabatha Yang, education and outreach coordinator. "Tours should last 30 to 45 minutes." Entomologist Jeff Smith, curator of the Lepidoptera collection, will be discussing butterflies and moths.
  
  
• The UC Davis Bee Haven, located on Bee Biology Road, next to the Harry H.Laidlaw Jr. Honey Bee Research Facility, west of the central campus, will offer tours at noon and 2. Established in the fall of 2009, the Bee Haven is a half-acre demonstration garden operated by the Department of Entomology and Nematology. "We'll focus on how best to observe and identify bees in the garden, as well as suggested bee plants that grow well in our area with low water," said Christine Casey, academic program management officer of the Bee Haven.

  The Arboretum and Public Garden will provide two 30-45 minute tours, "Climate-Ready Tree Project: Texas Tree Trials." Groups will leave the Conference Center at 11:30 a.m. and 1:30 p.m.  The project mission is to see if trees from west and central Texas will do well in this climate. The project involved collecting seeds, propagating them and planting them in the Arboretum.
  
  
• The Phaff Yeast Culture Collection is planning self-guided tours of the UC Davis Brewery, used for teaching and research, according to Kyria Boundy-Mills, curator, Phaff Yeast Culture Collection, Food Science and Technology.
  Different yeast strains are used for different styles of beer. These include ale yeast strains, lager yeast strains, and Belgian beer strains that are hybrids of wild yeasts. UC Davis offers an undergraduate major in food science and technology, with an emphasis on brewing science. Training includes chemistry, biochemistry, microbiology, quality assurance, engineering, sanitation, packaging, malting and crewing. The program currently includes 18 students studying for their bachelor of science degrees,  and three students seeking their master of science degrees.
  
  
• The Botanical Conservatory is technically not offering tours, says manager Ernesto Sandoval "but we will be open to the public so people can wander through at their own pace and we'll regulate the number of people in the greenhouse at any one time.  They can see our revamped succulent and carnivore rooms as well as our Cacao, aka  'Chocolate Tree,' with fruits as well as coffee and a very happy vanilla plant all amongst an incredible diversity of plants from ferns to an assortment of orchids."

The UC Davis Biodiversity Museum Day is traditionally held on the Saturday of Presidents' Day weekend. However, last year's event was virtual, and this year's event is centrally located in an exposition.
