The insects, that is.
Bohart Museum of Entomology research associate John "Moth Man" De Benedictus and colleagues set up a blacklighting display during the Bohart's annual Moth Night, held July 20, hoping to find a diversity of moths and other night-flying insects.
"We saw just three species," he said, listing them as:
- Pelochrista eburata, a tortricid moth with no common name
- Platynota stultana, a tortricid known as the Omnivorous Leafroller Moth, and
- Ephestiodes gilvescentella, a pyralid moth known as the Dusky Raisin Moth.
Entomologists study and collect nocturnal insects with blacklighting. They hang a white sheet, affix an ultraviolet light, and await the arrival of moths, beetles and other insects drawn to the light.
What else arrived from 10 to 11 p.m.? "Numerous small flies, a couple of earwigs, a large longhorn beetle (probably Prionus californicus), and a few green lacewings," he reported.
In comparison, the 2019 Moth Night resulted in these finds:
Family Tineidae:
Opogona omoscopa (Opogona crown borer)
Family Tortricidae:
Clepsis peritana
Platynota stultana (omnivorous leafroller)
Cydia latiferreana (filbertworm)
Family Pyralidae:
Achyra rantalis (garden webworm)
Ephestiodes gilvescentella (dusky raisin moth)
Cadra figuliella
Family Geometridae:
Digrammia muscariata
Family Noctuidae:
Spodoptera exigua (beet armyworm)
Spodoptera praefica (western yellow-striped armyworm)
Parabagrotis formais
De Benedictus has blacklighted for 37 years. His moth collection of some 600 species from the Stebbins Cold Canyon Reserve and 300 species from his backyard in Davis is housed in the Bohart Museum.
De Benedictus displayed his collection that includes the Dusky Raisin Moth, "the most common moth in Davis," he said. It's been recorded not only in California and Arizona, but in Oklahoma, Utah, Montana, Alberta an British Columbia. The moth is so named because its larvae feed on raisins (as well as prunes, walnuts, yeast and the like).
De Benedictus, who holds a master's degree in entomology (1998) from UC Berkeley, studied with major professor and noted entomologist Jerry Powell (1933-2023).
"Jerry Powell once estimated that there are about 17,000 North American butterflies and moths," De Benedictus commented. "I would not be surprised if it's closer to 20,000."
Every year De Benedictus helps coordinates the "Mid-Winter Lepidopterist Gatherings," a legacy of Powell. The gatherings are traditionally held annually at either the Essig Museum or the Bohart Museum "for colleagues to exchange information on moths and butterflies."
The Bohart Museum, located in Room 1124 of the Academic Surge Building, 455 Crocker Lane, is the home of a global collection of eight million insect specimens, plus a live petting zoo and a gift shop. Director is Professor Jason Bond, the Evert and Marion Schlinger Endowed Chair, UC Davis Department of Entomology and Nematology, and associate dean, Agricultural Sciences, UC Davis College of Agricultural and Environmental Sciences.

The open house showcased moths, in celebration of National Moth Week, and spotlighted flies, in keeping with the 10th International Dipterology Congress, held July 16-21 in Reno. Bohart officials dedicated the open house to the late Jerry Powell, international moth authority and a former director of the Essig Museum of Entomology, UC Berkeley, who died July 8 at age 90.
A blacklighting display, near the entrance to the Bohart Museum, drew night-flying insects to a white sheet, illuminated by an ultraviolet light.
"There were not many moths," said "Moth Man" John de Benedictus, a research entomologist associate with the Bohart Museum and a former graduate student of Powell's. "Only about 5 or six in all. All but two were the so-called Dusky Raisin Moth, Ephestiodes gilvescentella,which comes as no surprise as it is the most common moth in my yard and probably throughout Davis. Its caterpillar feeds on a wide variety of plants, including dried fruit and nuts, but it is not a major pest. There were two granite moths, probably Digrammia californiaria, and/or Digrammia muscariata. The younger kids entertained themselves by pointing out or trying to catch the other insects that flew in, mainly gnats and other small flies; a few beetles, including lady bugs; some aquatic bugs; and a couple of lacewings and earwigs. An older boy collected some ants that marched to the sheet."
Entomologist Jeff Smith, curator of the Bohart Museum's Lepidoptera collection, and Bohart associate and naturalist Greg Kareoelas, showed visitors many of the moth specimens, including death's-head hawkmoths, featured in the 1991 movie, Silence of the Lambs. In the movie, serial killer, Buffalo Bill (played by Ted Levine), stuffs death's-head hawkmoths inside his victims' throats. FBI trainee Clarice Starling (played by Jodie Foster) seeks the advice of the cannibalistic psychiatrist, Hannibal Lecter (played by Anthony Hopkins), to solve the mystery. The moths appearing in the movie are Acherontia stropos. The moth markings resemble a human skull.
The Bohart Museum, directed by UC Davis distinguished professor Lynn Kimsey, houses a global collection of eight million insect specimens, including some 500,000 moths or butterflies (60 percent moths and 40 percent butterflies). The museum is located in Room 1124 of the Academic Surge Building, 455 Crocker Lane, UC Davis campus. During the summer, the Bohart Museum is open to the public on Tuesdays from 2 to 5 p.m. For more information, contact the Bohart Museum at bmuseum@ucdavis.edu or (530) 752-0493.

The event, "A Night at the Museum," is free and family friendly. It takes place in several places: (1) inside the insect museum, located in Room 1124 of the Academic Surge Building, 455 Crocker Lane, UC Davis campus; (2) in the hallway of the Academic Surge Building; (3) directly outside the building for the blacklighting display; and (4) in the nearby Wildlife Classroom (Department of Wildlife, Fish and Conservation Biology) for a insect drawing demonstration.
The focus is on moths as this is National Moth Week. Entomologist Jeff Smith, who curates the Lepidopterist collection, will be in "the moth aisle" with Bohart associate and naturalist Greg Kareofelas to show specimens and answer questions.
At the Bohart table, inside the museum, fly experts from around the world--including dipterists at the California Department of Food and Agriculture--will answer your questions and show specimens. They were in Reno to participate in the 10th International Dipterology Congress, held July 16-21.
The hallway will be a plethora of exhibits and activities.
- There will be a memorial to the late international moth authority, Jerry Powell, former director of the Essig Museum of Entomology, UC Berkeley, who died July 8 at age 90. "Jerry's rearing program was the most extensive in the history of the study of New World Microlepidoptera," according to an Essig post. "For over 50 years he and his students processed more than 15,000 collections of larval or live adult Lepidoptera. Resulting data encompass more than 1,000 species of moths, through rearing either field-collected larvae or those emerging from eggs deposited by females in confinement. This total includes more than 60% of an estimated 1,500 species of Microlepidoptera occurring in California."
- Visitors can hold the tenants of the live insect petting zoo, including Madagascar hissing cockroaches and walking sticks and take selfies.
- Science educator and entomologist Nazzy Pakpour, who holds a bachelor's degree in entomology from UC Davis, and a doctorate in microbiology, virology, and parasitology from the University of Pennsylvania and did postdoctoral research at UC Davis, will be showcasing her new children's book, "Please Don't Bite Me! Insects That Buzz, Bite and Sting. The book is illustrated by Owen Davy. "All proceeds of book sales will go to the Bohart Museum, thanks to Nazzy's generosity," said Tabatha Yang, education and outreach coordinator. (See Pakpour's biography on One Aggie Network). Pakpour was a member of a collaborative team who worked on a malaria-proof mosquito that made Time Magazine's "50 Best Inventions of 2010." See Bug Squad post: "Malaria-Proof Mosquito Takes the Spotlight."
Nazzy Pakpour - Microscopes also will be set up in the hallway for visitors to view insect specimens.
Wildlife Classroom: Multiple insect drawing demonstrations, "How to Draw Bugs," will be given Professor Miguel Angel Miranda of the University of the Balearic Islands (UBI), Spain, who just returned from the International Dipterology Congress. He is a zoologist, entomologist and noted insect illustrator.

Two of those attending the four-day international Lepidopterists' Society conference held recently at the University of California, Davis, are as celebrated in Lepidoptera circles as the butterflies they study.
Robert Michael Pyle, a septuagenarian, and Paul Opler, an octogenarian, are international authorities on the insect order and share a love of science, teaching, and writing.
The two were among those who gathered at the Bohart Museum of Entomology during the Lepidopterists' Society conference. Lynn Kimsey, director of the Bohart Museum and a UC Davis professor of entomology, hosted two visits with several other Davis-based society members: retired research entomologist John De Benedictus; entomologist Jeff Smith, who curates the Bohart Museum's Lepidoptera collection; Bohart senior museum scientist Steve Heydon, and Bohart associate and naturalist Greg Kareofelas.
"This was our 68th annual meeting," said society president Brian Scholtens, a professor at the College of Charleston, South Carolina. "We have more than 1000 members worldwide."
This year's meeting, headquartered in the Independent Order of Odd Fellows Hall in downtown Davis, included two scientific gatherings at the Bohart Museum of Entomology.
The conference focused on the theme, "Insects in a Changing World Climate." "Attendees came from as far away as Finland to hear student and member speakers and to meet with their fellow Lepidopterists," said Smith. Marianne Horak of the Australian National Insect Collection received the prestigious Karl Jordan Medal, in absentia, at a banquet on the closing night.
The conference t-shirt and name tags depicted the California state insect, the dogface butterfly, Zerene eurydice.
Robert Michael Pyle
Robert Michael Pyle, a Yale-trained ecologist and a Guggenheim fellow, is the founder of the Xerces Society for Invertebrate Conservation. He has authored 23 publications, including the comprehensive National Audubon Society Field Guide to North American Butterflies, a go-to reference source. Among his other insect-related books: Chasing Monarchs: Migrating with the Butterflies of Passage, which chronicles his 9,000-mile journey to discover the secrets of the monarchs' annual migration. For his book, Mariposa Road: The First Butterfly Big Year, Pyle sought to track, firsthand, the 800 species of butterflies known in the United States. The book is a result of his 88,000 mile journey.
Pyle, now a resident of Grays River, Washington, recently published Magdalena Mountain: A Novel, about three Magdalenas:
- Mary, a woman on an uncertain journey;
- Magdalena Mountain, "shrouded in mystery and menace" and
- The Magdalena alpine butterfly, an all-black alpine butterfly, considered "the most elusive of several rare and beautiful species found on the mountain."
While at the Bohart Museum, Pyle delighted in examining the Magdalena specimens.
Professor Paul Opler, attending with his wife, naturalist/writer/nature photographer Evi Buckner-Opler, is a special appointment professor at Colorado State University. He is best known for his research on insect host relationships of Lepidoptera and tropical ecology and his service as first editor of American Entomologist, published by the Entomological Society of America (ESA). A fellow of ESA and a prolific writer, he authored field guides to both eastern and western butterflies. He is also known for his contribution to Moths of Western North America, and his role as scientific editor of "Status and Trends of Our Nation's Biological Resources."
UC Berkeley Reunion
Three entomologists, trained directly or indirectly by Professor (now emeritus) Jerry Powell of UC Berkeley reunited at the Bohart gathering: Dan Rubinoff, professor of entomology and director of the University of Hawaii Insect Museum, Honolulu; "Moth Man" John De Benedictus, retired UC Davis research entomologist; and Paul Opler, who retired from the U.S. Fish and Wildlife Service as the first entomologist in the Endangered Species Program and then accepted a special appointment professor in the Department of Bioagricultural Sciences at Colorado State University.
All three received degrees in entomology from UC Berkeley. Opler (Ph.D) and De Benedictus (Masters) studied with Powell, while Rubinoff (Ph.D) studied with Powell's successor, Felix Sperling.
At the Bohart gathering, director Lynn Kimsey gifted the attendees with a copy of the museum's innovative calendar featuring humorous sentences she collected from students in her classroom. UC Davis entomology student/artist Karissa Merritt illustrated the calendar.
The Bohart Museum, located in Room 1124 of the Academic Surge Building on Crocker Lane, is the home of nearly eight million insect specimens and the California Insect Survey. They're used as an "insect library" or references during identifications. They're also a permanent record of insect species' distribution in time and space.
In addition, the Bohart Museum houses a gift shop and a live "petting zoo," comprised of Madagascar hissing cockroaches, walking sticks and tarantulas.
