Oh, the questions that Lynn Kimsey, director of the Bohart Museum of Entomology, fielded at the Bohart's first-ever virtual symposium, held Friday morning, May 22.
For nearly an hour (11 to 11:45), Kimsey answered questions about the Asian giant hornet (aka "the murder hornet," so labeled by the news media); earwigs, native bees, midges, cockroaches, butterflies, yellow jackets and mosquitoes, and others.
Kimsey, a UC Davis professor of entomology and a two-time president of the International Society of Hymenopterists, related how a single colony of Asian giant hornets (Vespa mandarinia) was detected and destroyed on Vancouver Island, British Columbia, and a single hornet was found dead in Blaine, Wash. They are the first and only Asian giant hornets detected in North America. There is no invasion.
Unfortunately, she said, other insects are being mistaken for the giant hornets, including the Jerusalem cricket, known as "the potato bug." Even "dog vomit" is being mistaken for giant hornets, she said, pointing out that a Washington state colleague shared with her a photo of dog vomit. Someone figured a dog had swallowed an Asian giant hornet and "that's why it threw up," Kimsey told her virtual audience.
In Asia, "people live with them and they don't find them particularly troubling" any more than we do our yellow jackets, she said.
"In Asia, people eat these things, which shows you how terrified they are of them," quipped Kimsey, mentioning that her former graduate student, Matan Shelomi, now an assistant professor of entomology at the National Taiwan University in Taipei, Taiwan, has dined on the cooked larval and pupae dishes at Taiwanese restaurants.
The UC Davis professor said that the Japanese honey bees are larger than our European bees and form a ball to "cook" an Asian hornet. "They (honey bees) pick up the smell (of a hornet targeting their colony), cover it, and shiver their flight muscles to generate heat. They can raise it (the temperature) to well over 100 degrees Fahrenheit, which cooks the hornet."
Kimsey showed hornet and bee specimens from the Bohart collection. The hornet is about an inch and a half long, and "rarely gets up to 2 inches," despite what the media is saying, she said. "An inch and a half is still a big animal."
Unlike the honey bee workers, a hornet can sting multiple times. "Because it's such a large animal, it has more venom (than a honey bee)," she said, quipping "You could think about how nice they taste."
Kimsey said she's been stung by hornets and honey bees, and the sting of a honey bee hurts much more.
When she finished her presentation on "murder hornets," UC Davis spider specialist Jason Bond jokingly asked: “is there such a thing as a murder spider?” (A future Bohart Museum virtual house is scheduled to cover spiders. Bond, a noted spider authority and the Evert and Marion Schlinger Endowed Chair in Insect Systematics, UC Davis Department of Entomology and Nematology, recently discovered a new genus of spiders in Monterey County and is seeking public input on the species name. Suggestions are to be emailed to him at firstname.lastname@example.org by 5 p.m, June 1. See more here.)
Someone also asked Kimsey: "Are there murder mosquitoes?"
Other highlights of the virtual open house:
- On the website, you can access a drawing of an Asian giant hornet and download and color it. It is the work of UC Davis undergraduate student Meghan Crebbins-Oats. In addition, there's a drawing of a western yellowjacket to download and color; it is by artist Melinda Zavala.
- Also on the website, you can access a Swedish cinnamon roll recipe, posted there in connection with the Bohart's celebration of the birthday anniversary (May 23) of Swedish-born Linnaeus, "the father of modern taxonomy." UC Davis doctoral student Charlotte Herbert Alberts, of Swedish heritage, selected the recipe.
The Bohart Museum, located in Room 1124 of the Academic Surge Building, UC Davis campus, is the home of some 8 million insect specimens. It also includes a live "petting zoo" (including Madagascar hissing cockroaches, walking sticks and tarantulas) and a gift shop. In keeping with the mandated coronavirus pandemic precautions, the Bohart is closed until further notice.

If Lynn Kimsey, who directs the Bohart Museum of Entomology, UC Davis, had her say, the Asian giant hornets would NOT be nicknamed “the murder hornets.”
Kimsey, professor of entomology with the UC Davis Department of Entomology and Nematology and a past president (twice) of the International Society of Hymenopterists, will headline the Bohart Museum's virtual open house (Facebook Live) from 11 a.m. to 11:45 on Friday, May 22. It's the first-ever virtual open house; you can access it and ask questions on the Bohart Facebook page.
The theme is bees and wasps, so Professor Kimsey expects a number of questions about those obscure Asian giant hornets detected last fall in Canada and Washington state, the first confirmed sightings in North America. (One colony was detected and destroyed on Vancouver Island in September, and a single dead adult was found in Blaine, Wash. in December.
However, a news frenzy ("murder hornets are invading North America!") and considerable panic ensued.
So we asked Kimsey (she's granted six news media interviews on murder hornets to date), “What would you call them?”
“I'd just call them giant hornets,” she said matter-of-factly.
And then, in typical Kimsey humor, she deadpanned: “Or big, angry, orange-headed hornets!”
Meanwhile, the Bohart folks' unannounced test drive on Facebook Live earlier this week drew some unexpected participants and a few questions, such as:
- Do mantids often prey on hummingbirds?
- Why are some beetles metallic in color?
- What California beetle is attracted to fresh paint?
"On the website we will have a coloring sheet of the Asian giant hornet drawn by our scientific illustration intern Meghan Crebbins-Oats, an undergrad at UC Davis.”
The Bohart also will celebrate Linnaeus' birthday anniversary. Linnaeus (1707-1778), a Swedish taxonomist and physician known as "the father of modern taxonomy," was born May 23.
UC Davis doctoral student and Bohart associate Charlotte Herbert Alberts, who maintains strong ties to Sweden and taxonomy, thought that a traditional Swedish Fika with Kanelbullar to discuss taxonomy and Linnaeus would be "perfect."
"Hopefully people will be inspired to make some cinnamon buns, color, and think about names for Jason's new spider." (UC Davis professor Jason Bond discovered a new genus in Monterey County and is seeking a species name. (See Bug Squad blog about the spider and where to submit names.)
"The kanelbullars are not overly sweet and the dough is infused with cardamon," said Yang, who baked them for her family this week. They were a big hit.
Meanwhile, Kimsey is ready for lots of questions Friday morning on Facebook Live.
Don't be too surprised if she's asked about that "big, angry, orange-headed hornet."
