It was like a moth to a flame--or 400 moths to a flame--when a record crowd surged into the Bohart Museum of Entomology Moth Night for its July 30th open house.
After a two-year hiatus due to the COVID pandemic, "how great it was to have the doors open again for the public," said entomologist Jeff Smith, curator of the lepidoptera collection.
The 400-member crowd, thought to be the largest crowd at the Bohart, other than at UC Davis Picnic Day, was there to learn more about moths, draw images of moths on the sidewalks, enjoy an evening of camaraderie, and head outside to watch moths and other insects fly onto the hanging white sheet, part of the blacklighting demonstration display.
“People could draw whatever they wanted on chalk (outside the Academic Surge Building), but there were a lot of moths, although my kids went rogue and drew a soccer field and a figure,” said Tabatha Yang, the Bohart Museum education and outreach coordinator.
“We ran out of hot water, for the hot cocoa packets, and cookies half-way through!" Yand said, quipping "I thought we would be eating left over chocolate chip cookies at the Bohart all week, but alas that is not the case.”
The blacklighting display (white hanging sheet, ultraviolet light, and a generator) served as a demonstration site. "We had a few small beetles and a few small moths come in," Yang said.
The open house, which drew visitors from as far away as Alameda, took place the weekend before UC Davis summer sessions, so “the popularity among the college set was perhaps because of that, she said. "People were free from studying their required courses and so, on their own, they decided to seek out and learn about moths!”
Kareofelas fielded scores of questions about the Polyphemus moth, Antheraea polyphemus. “They are currently making their appearance in Davis, so a number of folks have seen them and had photos on their phones," he said. "A number of folks came with the desire to see a specific moth, and if we were lucky, it was located in the aisle we had open. Jeff (Smith) had pulled the drawers, from other aisles, with a number of specific species and had them labeled--a lot of questions about these drawers.”
"Some wanted to see the hummingbird moth, so I got to show Hyles lineata to a number of folks," Kareofelas said. "We had a lot of just plain 'good ol' interest' in seeing something and learning something about moths. The night started with a bang and went right to 11:00, still busy!"
"I was surprised at how popular the event was, how busy the store was, and how many folks showed up," Kareofelas said. "It was a great night!"
Smith spent the entire open house demonstrating how to spread the wings of moths. “I couldn't believe how many people came, and I was never ABLE to leave the table where I was demonstrating spreading," Smith said. "There was a constant group of people watching and asking questions, such as 'How did you become interested in this?' and of course, lots of questions on the spreading materials and techniques."
“The moment the door officially opened at 8 p.m., groups came in and headed in all different directions," Smith said. "One couple from Dixon was there with a group of scouts and they must have hung around my demo for 45 minutes with all kinds of interest and questions. People showed me photos on their cell phones of the white-lined sphinx moth, the ceanothus silk moth, and even a buck moth (Hemileuca) from Mono Basin."
Smith said he allowed "at least 10 different young people try their own hand at spreading a moth or two and that was really well received. I had a ziplock bag of surplus, papered moths and let some of the people take some for themselves. When it finally slowed a bit, I finally got up and couldn't believe it was already past 11 p.m." He headed over to the moth aisle where Kareofelas was still showing and answering questions about moths. "Greg did an amazing job. And, I ended up talking to a couple who work on campus until nearly 11:30."
Outside, the crowd marveled at the chalk drawings, including the tiger moths created by Srdan Tunic of UC Davis, a second-year master's degree student in art history. Skilled in street art and in academics (his Linked In profile indicates "Curating: creating bridges between art and people, ideas and objects"), Tunic is the co-founder, researcher and guide of Street Art Walks Belgrade, where he conducts lectures and tours on street art, graffiti, and the history of Belgrade. He holds a bachelor of arts degree (2008) in art history from the University of Belgrade, Serbia, and a master of arts in cultural policy and management (2017) from the University of Arts, Belgrade. He expects to receive his master's degree in art history from UC Davis in May of 2023.
The Bohart Museum, located in Room 1124 of the Academic Surge Building, 455 Crocker Lane, UC Davis campus, and directed by UC Davis distinguished professor Lynn Kimsey, houses a global collection of more than eight million insect specimens. It also houses a live "petting zoo" (Madagascar hissing cockroaches, stick insects and tarantulas) and an insect-themed gift shop. The latest t-shirt features a Jerusalem cricket, aka potato bug.

The free, family event takes place in the Bohart Museum, located in Room 1124 of the Academic Surge Building, 455 Crocker Lane, UC Davis campus. The event will focus on the biology and history of the butterfly. A family arts and crafts activity is also planned.
Found only in California, the rarely seen butterfly is also known as (1) "the flying pansy," referring to the male's spectacular black and yellow coloring, and (2) as a "dog head" butterfly (the markings on the male resemble a silhouette of a dog's head). The female is mostly solid yellow.
The butterfly's major breeding ground is in Auburn at a preserve maintained by the Placer Land Trust (PLT). The butterfly is there because its larval host plant--false indigo (Amorpha californica)--grows well there. "The dogface butterfly has a range from San Diego County to Sonoma County and is usually found in mountain and foothill locations," according to an article on the PLT website.

Meanwhile, the folks at the Bohart Museum of Entomology, including director Lynn Kimsey, museum scientist Fran Keller and Bohart associate Greg Kareofelas (he shares his expertise as a docent leading tours and delivering presentations for the Pacific Land Trust), hope to connect with the fourth grade students of Betty Harding and Shirley Klein in the Dailey Elementary School, Fresno, who advocated it as the state insect. The teachers and students enlisted the help of State Assemblyman Kenneth L. Maddy, who authored AB 1834. "His bill was read for the first time on March 15, 1972 and referred to the Assembly Committee on Government Organization, according to a state website.
"On May 25, 1972, with a committee vote of 6-2, Mr. Maddy failed to garner the needed eight votes to recommend the legislation to a floor vote. It wasn't clear why two members voted against the bill, but a bill to designate an official state fossil also gone down to defeat earlier in the day. The Fresno Bee wrote, 'Dog-Faced Butterfly Has Wings Clipped.'
"Assemblyman Maddy vowed to fight on and promised a better result when the full committee was present in the next week.
"Good to his word, Mr. Maddy moved the bill out of committee and to approval by the full Assembly on June 19. 1972.
"A month later, on July 20, the Senate voted 29-0 to approve AB 1834.
"On July 28, 1972, Governor Ronald Reagan signed Assembly Bill No. 1834 designating the California dog-face butterfly the official State Insect of California." (Read more on how the butterfly became the state insect under the Ronald Reagan administration.)
In 2013, Fran Keller, a UC Davis doctoral alumnus and now a professor at Folsom Lake College, published a 35-page children's book, The Story of the Dogface Butterfly that includes includes photos by Kareofelas and Keller and illustrations by then UC Davis student Laine Bauer. They earlier created a poster. Both the book and the poster are are available for sale in the Bohart Museum gift shop.
The book tells the untold story of the California dogface butterfly, and how schoolchildren became involved in convincing the State Legislature to select the dogface butterfly as the state insect. As part of their research, Keller, Kareofelas and Bauer visited the Placer Land Trust habitat of the butterfly. Kareofelas reared the insect from egg to adult, photographing all stages. At the open house, Keller will do a book reading for youths and their parents at 1:30 p.m. and 3:30 p.m.
Kareofelas has assisted with news documentaries on the butterfly:
- Rob on the Road, KVIE, Public Broadcasting Service (PBS)
- Capital Public Radio, National Public Radio (NPR)
The history of how the butterfly became the state insect actually begins in the 1920s with the Lorquin Entomological Society of Los Angeles. In an October 1929 article in The Pan-Pacific Entomologist, a publication of the Pacific Coast Entomological Society, J. D. Dunder of Pasadena credits the Lorquin Entomological Society with seeking "to establish a state insect for California." Out of three choices, the group voted on the California dogface butterfly.
Dunder wrote that the butterfly is "strictly a native California butterfly" and that "thousands of specimens are used each year in entomological art work for trays, bookends, plaques, etc., so the species is already fairly well known to the pubic."
Today its image graces a first-class U.S. stamp and our California driver licenses. It's also depicted on the California State Fair monorail. The Lone Buffalo Vineyards and Winery, Auburn, memorialized it on labels of specially bottled wine, with proceeds helping conservation efforts of the Placer Land Trust to protect the butterfly.
Take a look at the amazing images that Greg Kareofelas captured of the life cycle of the California dogface butterfly.

The California Honey Festival, set Saturday, May 7 from 10 a.m. to 5 p.m. in downtown Woodland, will focus on honey, bees, plants and pollination.
"UC Davis will have a slimmed down version this year," said Amina Harris, director of the UC Davis Honey and Pollination Center at the Robert Mondavi Institute, and a co-founder of the event. Launched in 2017, the Honey Festival hasn't been held since 2019 due to the COVID-19 pandemic. Some of the events on tap Saturday:
- The UC Davis Honey and Pollination Center will showcase its honey tasting wheel and offer free honey tasting.
- The California Master Beekeeper Program will staff two educational booths. Visitors can examine a bee observation hive, check out the beekeeping equipment and peer through microscopes. Kids' activities are also planned.
- The Bohart Museum of Entomology of the UC Davis Department of Entomology and Nematolgoy will showcase bee diversity in its specimen drawers. Its live "petting zoo" will include Madagascar hissing cockroaches and stick insects (walking sticks) that folks can hold, said Tabatha Yang, education and outreach coordinator.
- The UC Davis Arboretum and Public Garden will address pollinator needs and gardening.
- The Woodland Public Library will offer a children's reading hour.
- Uncle Jer's Traveling Bee Show will provide educational performances.
- The UC Davis Bookstores booth will contain honey, books, and other gifts for sale.
- Visitors can don a bee costume and get their picture taken in the UC Davis Pollination Park, a collaboration with the UC Davis Arboretum and Public Garden.
Harris said the festival will include live music, a beer and mead garden, and about 100 vendors selling everything from food to plants to arts and crafts. Admission to the festival is free. The first festival drew some 30,000 visitors.
An after-party is planned at The Hive, owned by Z Specialty Food, Woodland. Advance registration is required. Access https://zspecialtyfood.com/event/california-honey-festival-after-party/
(Note: This year the UC Davis Bee Haven, operated by the UC Davis Department of Entomology and Nematology, won't be able to participate due to scheduling conflicts, said academic program management manager Christine Casey.)

Professor Denison, who retired in 2018, joined the department in 1992 and advanced to professor in 1997. He served as a researcher in the UC Davis SRP, funded by National Institute of Environmental Health Sciences (NIEHS), for more than 25 years.
Over a 44-year period, Denison focused his research on understanding the molecular mechanisms by which a protein known as the Ah receptor mediates the biological/toxicological actions of dioxins and related chemicals. He was widely acclaimed for his development of the Chemical Activated LUciferase gene eXpression (CALUX) assay, a cell-based bioassay used to detect specific environmental contaminants, including, but not limited, to dioxin-like chemicals and environmental hormones (endocrine disruptors).
The test, approved by the intergovernmental Organization of Economic Cooperation and the U.S. Department of Environmental Protection Agency, is the international standard for detecting environmental contaminants in the protection of human health. Denison also made other seminal contributions to the Ah receptor field and was a leader in advancing the study of Ah receptor biology, said UC Davis distinguished professor Bruce Hammock, the founding director of UC Davis SRP and a close friend and colleague of Denison's.
“He is best possibly known for his fundamental work on the mechanism of action of TCDD and the translation of this knowledge into a quantitative, rapid and inexpensive assays for tetrachlorodioxin like chemicals and other chemicals that bound to the aryl hydrocarbon hydroxylase receptor," Hammock said. "He went on to use the CALUX format to measure a number of other small molecule receptor interactions. Mike was also funded for much of his career by competitive grants from NIEHS, including his MS and PhD work.”
Robert Rice, professor and chair of the Department of Environmental Toxicology, said that "Mike's absence leaves quite a void in our department. Even in retirement, he continued to be a source of wisdom and amusement, and he was still an inspiration to students."
Rice added that he first met Denison in 1992 when he joined the faculty, "and I ended up being department chair in recent years after he declined the position."
Denison, trained in biology, marine biology, animal physiology and environmental toxicology, received his associate of arts degree in biology from the County College of Morris, N.J. in 1975, and his bachelor's degree in marine biology from St. Francis College, Biddeford, Maine, in 1977. He obtained his master's degree in animal physiology from Mississippi State University, Starkville, in 1980, and went on to receive his doctorate in environmental toxicology from Cornell University, Ithaca, N.Y., in 1983. Denison did postdoctoral research at the Department of Clinical Pharmacology, Hospital for Sick Children, Toronto, Canada, from 1983 to 1985, and with Stanford University's Department of Pharmacology, 1985-1988.
Denison began his academic career as an assistant professor in the Department of Biochemistry at Michigan State University, East Lansing, from 1988 to 1992, and then relocated to the UC Davis Department of Environmental Toxicology.
Michael and his twin brother, Steven, were born on Dec. 8, 1954, in Shirley, Mass., the sons of Alan (deceased) and Alma Denison. While the father served in the U.S. Army, the family lived in numerous places around the world and settled in Wharton, N.J. when boys were 11.
“Michael was a happy and optimistic person,” said his widow Grace Bedoian, who retired in 2014 as a UC Davis SRP administrator and a member of the Hammock lab. “The only thing he took seriously was science, which he loved."
“His typical day was spent at work, conducting his research and mentoring students, returning home and making a wonderful dinner at the end of the day, and then retreating to his home office to work until the wee hours of the following morning," she said. "He maintained curiosity and wonder of the world around him. He loved to solve problems and figure out how things worked. He was generous with his friends and colleagues alike and always quick to offer his services to those in need."
Denison is survived by his widow, Grace; his mother, Alma; two brothers (Steven and Daniel) and their wives (Gloria and Angela); two nieces, two nephews, and several grandnephews.
The family thanks the staff at Yolo Cares of Davis for “their exceptional expertise, kindness and compassion in providing in-home hospice care for Michael. All of the staff members at Yolo Cares are truly angels on this earth.” In lieu of flowers, donations may be made to Yolo Cares by contacting (530) 758-5566 or http://www.yolocares.org.
Donations also may be made to the Michael S. Denison, Ph.D. '83 Environmental Toxicology Research Fund, an endowment created at Cornell University by a colleague. Checks payable to Cornell University may be mailed to Cornell University, Box 37334, Boone, IA 50037-0334. In the memo field or in the correspondence, donors are asked to add: Michael S.

The 108th annual UC Davis Picnic Day will include scores of insect-related displays and activities sponsored by the UC Davis Department of Entomology and Nematology. Entomological events will take place at Briggs Hall; the Bohart Museum of Entomology (Academic Surge Building on Crocker Lane); and in the courtyard of Green Hall (formerly Life Sciences).
Free and open to the public (as is parking), it will be the first in-person Picnic Day in nearly three years. The theme is "Rediscovering Tomorrow."
Danielle Rutkowski, doctoral candidate in the lab of associate professor Rachel Vannette, is planning and coordinating the UC Davis Graduate Student Association (EGSA) events.
"We're all so excited that it's in-person again," said Jill Oberski, EGSA president. "Grad students usually run most of the entomology exhibits, but most of the younger graduate students have never been to a 'real' Picnic Day—so we finally have the chance to pass the experience on to them. It's always crazy and exhausting but it's so much fun, and a really great opportunity to engage with the public."
EGSA will be selling a number of t-shirts, both classic attire and new designs. New designs are "UCD Amblypygid," designed by Emma Jochim of the Jason Bond lab (it's EGSA's first arachnid shirt) and the limited-edition 'Mosquito Picnic' for Picnic Day 2022, designed by Oberski. "And we have stickers, masks, and several years' worth of back stock we would love to sell!" Oberski noted, adding that EGSA takes both cash and credit cards. Some of the classic T-shirt designs, such as The Beetles, sell fast. The link to EGSA's online store: https://ucdavisentgrad.
