Moths, anything about moths, was the kind of event that Powell loved. He was an associate of the Bohart Museum and a scientific collaborator, identifying scores of insects and attending many of the Leipidopterist Society meetings held there.
The open house, free and family friendly, is set from 7 to 11 p.m., Saturday, July 22 in Room 1124 of the Academic Surge Building, 455 Crocker Lane, UC Davis, campus.
Plans call for scientists to set up their traditionalblacklighting (ultraviolet or UV) display to attract moths and other night-flying insects. Bohart Research Affiliate John DeBenedictus, a retired UC Davis Staff Research Associate, also known as "The Moth Man," usually heads the blacklighting project. De Benedictus received his master's degree in 1988 from UC Berkeley, studying with Powell. "I spent more time in the field with Jerry than any other grad student," he related. "I was privileged to be Jerry's student and lucky to have become his friend."
Powell and Paul Opler (1938-2023) co-authored Moths of Western America, published in 2009.
In a tribute to Powell on its website, the Essig Museum posted in part:
"In his teen years he was heavily influenced by Charles 'Harbie' Harbison, who ran the Junior Naturalist Program at the San Diego Museum of Natural History, and sparked an interest in Jerry for butterflies and moths. Seeing his potential, Harbie recommended Jerry for the Entomology program at UC Berkeley, where he received his BS in 1955 and his PhD in 1961. While climbing through the ranks of Junior Entomologist (1961-62), Assistant Entomologist (1962-67), Associate Entomologist (1967-73), Entomologist (1973-94), Lecturer in Entomology (1964-69), Associate Professor (1969-73), and Professor (1973-94) at UC Berkeley, Jerry also became Curator (1972-2018) and Director (1993-1999) of the Essig Museum of Entomology (1972-1999) and Project Leader for the California Insect Survey (1963-1999). Although he retired as Director in 1999, Jerry remained a professor of the Graduate School until 2012 and maintained an active research program in Lepidoptera life histories and systematics until 2018, advising many students along the way. (See more on Essig website.)"
"Jerry's rearing program was the most extensive in the history of the study of New World Microlepidoptera," according to the 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."
Powell gained international recognition when he detected the agricultural pest, the light brown apple moth, Epiphyas postvittana, in a ultralight (UV) trap on July 19, 2006 in his backyard in Berkeley.
In an email to colleagues on July 9, Peter Oboyski, executive director of the Essig Museum of Entomology, wrote: "With a heavy heart I am sad to report that professor Jerry Powell passed away this weekend. His contributions to our knowledge of California entomology, microlepidoptera, and insect life histories are inestimable, as is the value of the training he provided to his students. As one of those students, I am eternally grateful for the time, energy, and knowledge Jerry shared with me in the museum and the field."
"A consummate field biologist, Jerry's knowledge and interests were broad, allowing him to read landscapes and discover the most interesting and cryptic of species interactions," Oboyski noted. "This is well documented in over 220 publications, but also in the 60+ years of his field notes and rearing records that we are currently digitizing. He is the collector of over 400 holotypes of various insect orders, described over 170 species and 14 genera of moths, and honored by 41 patronyms. He also published papers on Hymenoptera, Coleoptera, Diptera, Dermaptera, and a Nematode. His legacy is impressive and will long be remembered."
Powell described himself as a "MothNut" on his vehicle license plate, and also displayed a sticker, "Larvae on Board."

Step into your garden, walk over to a community park, or hike in the wilderness and see what's out there.
And take along the newly published, newly revised "The Field Guide to California Insects."
It includes more than 600 insect species. Not sure what species of butterfly that is? Want to know if that's a Valley carpenter bee? What's that species of praying mantis you just found? Take a look at the text and photos. Chances are you'll find them in this handy book.
It's a California Natural History Guide and published by the University of California Press. If you're into entomology, you'll probably recognize the names of the four authors:
- Kip Will, entomologist, insect systematist, and former director of the Essig Museum of Entomology at UC Berkeley
- Joyce Gross, noted insect photographer (she works as a computer programmer with the Berkeley Natural History Museums at UC Berkeley)
- Dan Rubinoff, who grew up chasing insects in California and is now a professor of entomology and director of the University of Hawaii Insect Museum
- Jerry Powell, emeritus professor, UC Berkeley, and former director of the Essig Museum of Entomology
We remember reading the first edition, California Insects, published in September 1980 and authored by Professor Powell and (the late) Charles Hogue.
So this revision is 40 years in the making.
It's billed as the only California-specific, statewide book devoted to all groups of insects:
"Engaging accounts focus on distinguishing features, remarkable aspects of biology, and geographical distribution in the state. An accessible and compact introduction to identifying, understanding, and appreciating these often unfamiliar and fascinating creatures, this guide covers insects that readers are likely to encounter in homes and natural areas, cities and suburbs, rural lands and wilderness. It also addresses exotic and invasive species and their impact on native plants and animals. Field Guide to California Insects remains the definitive portable reference and a captivating read for beginners as well as avid naturalists."
The authors point out that worldwide, there are only a million described insects, and that's "more than five times the number of all animals combined." They also note that "estimates of the number remaining to be described and named vary between three million to 30 million or more."
Thirty million! Can you imagine?
The authors define what makes an insect, expanding on growth and reproduction, breathing and circulation, feeding and stinging. They write about the distribution and diversity of the California insect fauna; how insects are classified, and even how to make an insect collection, something most high schoolers will be asked to do.
The book offers you information on dragonflies and damselflies, mantises, stick insects, beetles, fleas, flies, mosquitoes, earwigs, moths and butterflies, and booklice--and more.
It's a fantastic book--well-researched, well-written, well-illustrated, and an opportunity for you to become not a Big Game Hunter, but a Little Game Hunter.
By the end of the book, you may even decide to study entomology. (And there's plenty of opportunities in California, including at the UC Davis Department of Entomology and Nematology)
You may also want to become an insect photographer: plant a pollinator garden and they will come. Below are some of the backyard or household images you can capture.

Have you ever seen a plume moth?
Or has a plume moth ever seen you?
We spotted a pterophorid plume moth (family Pterophoridae) yesterday on our back door in Vacaville, Calif. The t-shaped moth stayed in the same spot the entire day, from dawn to dusk, even when we entered and exited the door multiple times.
Its shape is what makes it unusual. Butterfly expert Art Shapiro, distinguished professor of evolution and ecology at the University of California, Davis, told us awhile back that the "T-square shape is classic."
In some respects, the pterophorid plume moth is fit to a "T."
At rest, the plume moth holds its slender wings at right angles to body, giving it a T-shaped profile.
In his book, California Insects, UC Berkeley entomologist Jerry Powell (now emeritus) explains why they're called plume moths..."because the forewings are deeply notched and the hindwings are divided into three linear parts, each with long scale fringes. When perched, the insects roll the forewings around the folded hindwing plumes, resulting in peculiar sticklike or craneflylike appearance, unlike any other moth."
Most are nocturnal and are attracted to lights, Powell adds. (Like porch lights!)
Its ancestors lived millions of years ago. Wikipedia tells us that a fossil species from the extant genus Merrifieldia originates from the Oligocene of France. The Oligocene, a geologic epoch of the Paleogene Period, occurred 33.9 million to 23 million years ago. Today some 160 species of plume moths live in North America.
So why did the plume moth visit us? Well, it's a common moth. The adults feed on nectar and pollen (plenty of that in our pollinator garden) and caterpillars of some of the species chew the leaves of garden plants, including geraniums and snapdragons (we have both).
We also have artichokes, and the larvae of one species, the artichoke plume moth, can be a pest when the vegetable is grown as a perennial, according to the UC Statewide Integrated Pest Management Program website.
One thing is for sure: once you see the plume moth, you'll always recognize it.

A pollinator garden is a study in diversity--and of inclusion and exclusion.
The residents, the immigrants, the fly-bys, the crawlers, the wigglers, the jumpers. The big, bad and bugly. The prey and the predators. The vegetarians and carnivores.
The nectar-rich flowers attract honey bees, bumble bees and butterflies. And right near them are the predators: the praying mantids, dragonflies and assassin bugs.
The assassin bugs, family Reduviidae, are ambush predators. They resemble human assassins (or at least those on the movie screen!): long narrow neck, beady eyes, and sturdy body. When they ambush a predator, they stab it with their rostrum, inject venom, and suck out the juices. Or as UC Berkeley entomologists Jerry Powell and Charles Hogue write in their book, California Insects, "The victims, which include all kinds of insects, are snatched by quick movements of the forelegs, and immediately subdued by a powerful venom injected through the beak."
Such was the case with the assassin bug, Zelus renardii, this week. We watched one lie in wait on a Mexican sunflower (Tithonia); we watched another dine on an unidentifiable prey on a milkweed blossom; and we watched yet another stab a lady beetle (aka lady bug) on a leaf.
Everybody eats in the pollinator garden.

The scientists and butterfly/moth enthusiasts who gathered Saturday, Feb. 9 for the Northern California Lepidoptera Society meeting in the Bohart Museum of Entomology at the University of California, Davis, did all that: identify specimens and engage in collaboration and camaraderie.
They ranged from those early in their career, to mid-point, to the height of their career, to retired.
The group meets for a mid-winter gathering once a year, alternating between the Bohart Museum of Entomology at UC Davis and the Essig Museum of Entomology at UC Berkeley.
Senior museum scientist Steve Heydon, Bohart associate John "Moth Man" DeBenedictis; and Jeff Smith, curator of the butterfly/moth section at the Bohart hosted the event, assisted by Lynn Kimsey, director of the Bohart Museum and Bohart associate and naturalist Greg Kareofelas.
In their meeting notice, Heydon, DeBenedictis and Smith noted that those attending could bring specimens, photos, PowerPoint presentations "or slides from collecting trips and tales of collecting triumphs to share with others
and that "attending lepidopterists may be able to help you identify specimens and the museum collection will be open for yoour inspection."
Retired public health entomologist and Bohart associate Dick Meyer of Bakersfield, known as "the mosquito guy," was there. He recently retired as assistant manager of the Orange County Vector Control Agency. He did not bring any of his collection, but he did tell us that he has 225 drawers of insects at home, including 71 drawers of butterflies. "Did you know that the highest diversity of butterflies in the country is in Kern County?" he asked. Meyer, who holds a doctorate in entomology, studied with major professor Richard M. Bohart Jr., for whom the Bohart Museum is named.
Among those participating:
- Bohart associate Jerry Powell, emeritus director of the Essig Museum, and co-author of California Insects.
- Marc Epstein, senior insect biosystematist for the California Department of Food and Agriculture and author of the book, Moths, Myths and Mosquitoes: the Eccentric life of Harrison G. Dyer Jr.
- Kelly Richers, treasurer of the Lepitopterists Society and an affiliate of Essig Museum of Entomology who is also afield associate with the Los Angeles County Museum of Natural History and member of board of directors of the Wedge Entomological Research Foundation
- Lawrence "Larry" Allen of Calaveras County, author of A Field Guide to the West Coast Butterflies of the United States, one of the books available in the Bohart Museum's gift shop (he donated all sales of his book that day to the Bohart).
- Arthur Shapiro, UC Davis distinguished professor of evolution and ecology and author of Field Guide to Butterflies of the San Francisco Bay Area and Sacramento Valley Regions.
- Entomologist Rick Kelson, who directs the butterfly habitat at Six Flags Discovery Kingdom, Vallejo
- Bohart associate Bill Patterson, former graduate student of Richard Bohart
- Rosser Garrison, research associate with the California State Collection of Arthropods, retired senior insect biosystematist, California Department of Food and Agriculture, and co-author of Dragonfly Genera of the New World: An Illustrated and Annotated Key to the Anisoptera
- Don Miller, professor at Chico State University who teaches entomology in the Department of Biological Sciences
- Ryan Hill, professor at University of Pacific, Stockton
- Chris Tenney, retired educator from Pacific Grove
- Jeffrey Caldwell, known for his ecological restoration
- John Lane, one of first graduate students of Art Shapiro (Lane received his master's degree)
- Paul Johnson, biologist with the National Parks Service
- Hobbyist Jeff Baier of Napa
- Physician Val Albu of Fresno
- And many more...
At the last gathering in the Bohart, Kelly Richers, who compiles the California Moth Specimen Database, maintained at the Essig Museum since 1996 as a resource to better survey and understand California moths, said of the systematists: "We're a dying breed."
This year self-described "aspiring entomologist" Madison Cunha of Modesto attended with her mother, Christine Cunha. True to her love of insects, Madison wore a dress adorned with a beetle pattern.
Scientists say that 180,000 species of the Lepidoptera are described, in 126 families and 46 superfamilies.
"The Lepidoptera are among the most successful groups of insects. They are found on all continents, except Antarctica, and inhabit all terrestrial habitats ranging from desert to rainforest, from lowland grasslands to mountain plateaus, but almost always associated with higher plants, especially angiosperms (flowering plants). Among the most northern dwelling species of butterflies and moths is the Arctic Apollo (Parnassius arcticus), which is found in the Arctic Circle in northeastern Yakutia, at an altitude of 1500 m above sea level. In the Himalayas, various Apollo species such as Parnassius epaphus have been recorded to occur up to an altitude of 6,000 miles above sea level."--Wikipedia.
