The open house, themed "Social Wasps," is free and family friendly. Parking is also free.
Kimsey defines social wasps as "wasps that live together and cooperate in a colony, with female workers and a queen; only the queen has babies."
What drew her to study social wasps? "I just like stinging things in general and their anatomy and social behavior are really interesting."
Kimsey lists some of the common myths about social wasps as:
- They are often seen as malevolent beings out to get you and will chase you
- That they serve no purpose except to annoy us
- If you're allergic to bee stings you'll be allergic to wasp stings
- A copper penny place on a sting will make it go away
The public should know that social wasps "provide valuable ecosystem services; do pest control, and assist in nutrient recycling and pollination," she said.
"There are about 2,000 described species of social wasps worldwide," Kimsey said, and probably around 500 species undescribed.
The Bohart Museum has approximately 50,000 vespids in its collection, "and clearly the most popular is the Northern giant hornet, Vespa mandarinia," she said. The press dubbed it "Murder hornet." The Entomological Society of America recently changed its common name, "the Asian giant hornet," to "northern giant hornet."
The hornet, considered the world's largest hornet, is native to Asia. It was first detected in the Pacific Northwest in 2019, and with nests found in 2021.
Kimsey is a recognized authority on insect biodiversity, systematics and biogeography of parasitic wasps, urban entomology, civil forensic entomology, and arthropod-related industrial hygiene. She holds bachelor and doctoral degrees from UC Davis. She joined UC Davis entomology faculty in 1989, and has served as director of the Bohart Museum since 1990.
She plans to retire this year, but not from research and public service.
Kimsey served as president of the International Society of Hymenopterists from 2002-2004, and as a member of the board of directors of the Natural Science Collections Alliance in 2000 and 2001. The Pacific Branch, Entomological Society of Ameica (PBESA) singled her out for its highest honor, the C. W. Woodworth Award, in 2020. She received the PBESA Systematics, Evolution, and Biodiversity Award in 2014 and was a member of 'The Bee Team' that won the PBESA Outstanding Team Award in 2013. The UC Davis Academic Senate honored her with its Distinguished Scholarly Public Service Award in 2016 in recognition of her outstanding work. She received the UC Davis College of Agricultural and Environmental Sciences (CA&ES) Exceptional Faculty Award in 2023.
The Bohart Museum also houses a live "petting zoo" (Madagascar hissing cockroaches, stick insects, tarantulas and more), and an insect-themed gift shop.

The event is free and family friendly. It is the Bohart's first special event of the fall season.
Visitors will learn about the smallest fairy wasps to the "murder hornets"; what role wasps play in plant galls and figs; and how to distinguish a parasitoid from a parasite. Lynn Kimsey, director of the Bohart Museum and a UC Davis distinguished professor of entomology, will discuss the Asian giant hornet, Vespa mandarinia, dubbed by the news media as “the murder hornet." The Entomological Society of America recently established as its official common name, “northern giant hornet.”
A single colony of the Asian giant hornet was found and destroyed Sept. 18, 2019 in Nanaimo, Vancouver Island, Canada, and a single dead hornet was found Dec. 8, 2019 in nearby Blaine, Wash. Since then, it also has been sighted-- and destroyed--in both Canada and Washington state.
Kimsey, an authority on the giant hornet and a two-term past president of the International Society of Hymenopterist, says the insects probably "hitched a ride" in a cargo box shipped from Asia to a North American seaport. The insect is considered the world's largest species of hornet and can reach up to 2 inches in length. A few hornets can destroy a bee colony, decapitating the honey bees, in a matter of hours.
Kimsey and two other wasp experts published “The Diversity of Hornets in the Genus Vespa (Hymenoptera: Vespidae; Vespinae); Their Importance and Interceptions in the United States,” in the journal Insect Systematics and Diversity in May of 2020. (See https://bit.ly/3BVZ34Y)
Lead author Allan Smith-Pardo, U.S. Department of Agriculture Animal and Plant Health Inspection Service (APHIS), and co-authors James Carpenter of the American Museum of Natural History's Division of Invertebrate Zoology, and Kimsey covered 22 species of hornets, including V. mandarinia.
Fairy wasps, which belong to the family of chalcidoid wasps, are tiny insects that include the world's smallest known insect, with a body length of 0.139mm, and the smallest known flying insect, only 0.15mm. All known fairy wasps are parasitoids of the eggs of other insects.
A family arts-and-crafts activity is also planned at the open house.
The Bohart Museum is the home of a global collection of eight million insect specimens. It also houses a live “petting zoo,” comprised of Madagascar hissing cockroaches, stick insects and tarantulas; and a gift shop with insect-themed items.
