A landmark textbook on the newly emerging field of biodemography, lead-authored by UC Davis distinguished professor James R. Carey, has evolved into another landmark: Carey has created, recorded and published a first-of-its-kind video guidebook with free worldwide access.
The video guidebook showcases the 480-page textbook, Biodemography: An Introduction to Concepts and Methods (Princeton University Press, 2020), co-authored by Deborah Roach, professor and chair of the University of Virginia's Department of Biology. Carey and Roach define the pioneering field of biodemography as “integrating biology, mathematics and demography.”
Carey, a member of the UC Davis Department of Entomology and Nematology faculty since 1980 and a senior scholar with the UC Berkeley Center on the Economics and Demography of Aging (CEDA), opted to create the video playbook because “we believe the contents should be available to anyone interested in any aspect of biodemography regardless of their access to the book or their primary language.”
The video guidebook, now online on the UC Berkeley Population Sciences website, is unique in that never before has a scientific textbook author produced, scripted and narrated videos that encompass a book's entire content. The playlist includes 175 separate presentations, closed captioned in English and subtitled through YouTube in 300 different languages. The content covers the contents of his entire biodemography book with video modules on content ranging from life tables, mortality models and reproduction to stable population theory, matrix models and applied demography. He also has several dozen videos on best practices in visualization and presentation strategies.
Basically, the video guidebook is a cross-media learning experience that's viewers will find engaging, enduring and enjoyable. "Readers can scroll, scan and peruse the book's contents as well as add notes, bookmark pages, and highlight text,” Carey said. “Unlike books video content can be easily added or updated and as well as both closed captioned and foreign language subtitled.”
His playlist includes demographic basics, life tables, mortality, reproduction, population models, and such topics as the Donner Party tragedy, the Titanic disaster, Napoleon's Grand Armée, and “Why the Oldest Person in the World Keeps Dying.”
Carey also delves into “Entomology and Insect-Related Videos” (see https://bit.ly/3lgYcD2), ecology and conservation biology, and other specialty grouped topics. In addition, his playlist includes video appendices of African elephants and mountain gorillas that he recorded on his teaching trips to Africa.
Carey describes demography as “the taproot of an interdisciplinary tree containing multiple branches whose demographic topics range from health, disease, marriage and fertility to anthropology, paleontology, history, and education. Our book now adds a new branch to this tree—biodemography.”
Highly honored for his research, teaching and public service Carey served as the principal investigator of a 10-year, $10 million federal grant on “Aging in the Wild,” encompassing 14 scientists at 11 universities.
Carey won a 2018 global award in the Robert Foster Cherry Award for Great Teaching Program, an academic competition sponsored every two years by Baylor University, Waco, Texas. He received the 2015 Distinguished Achievement in Teaching Award from the Entomological Society of America (ESA) and the 2014 Distinguished Teaching Award from the Pacific Branch of ESA. The UC Davis Academic Senate honored him as the recipient of its 2014 Distinguished Teaching Award, given to internationally recognized professors who excel at teaching.
Carey is a fellow of four organizations; American Association for the Advancement of Science, Entomological Society of America, California Academy of Science and the Gerontological Society of America. He holds a doctorate in entomology from UC Berkeley.

Do you have a question about wasps or want to learn more about them?
It's the first open house of the academic year and will focus on Asian giant hornets, aka "murder hornets," pteromalids, oak galls, and fig wasps, among others.
The family arts-and-crafts activity will be to create "gall ghosts."
Visitors are also invited to hold and take images of the insects from the live "petting zoo," which will include Madagascar hissing cockroaches and stick insects, also known as "walking sticks."
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 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.
Other special events planned by the Bohart Museum this year include:
Saturday, Oct. 15, 1 to 4 p.m.
Insects, Art & Culture
Visitors will learn about insects through the lenses of art and culture. This event is part of Spirit Week (Oct. 10-16) for Aggie students, parents and alumni, but all are welcome.
Saturday, Oct. 15, 11 to 11:50 a.m.
Special Talk: Plants, Insects and Art: Mary Foley Benson's Scientific Illustrations
Location: Teaching and Learning Complex (TLC) Building, 482 Hutchison Drive, UC Davis campus
This event is part of Spirit Week for Aggie students, parents and alumni, but all are welcome. Srdan Tunic, a candidate for a master's degree in art history and a Bohart associate, will be highlighting the scientific illustrations of Mary Foley Benson (1905-1992), formerly of the U. S. Department of Agriculture's Bureau of Entomology and the Smithsonian Institution and who later worked for UC Davis entomologists. Much of her work appears on campus. (See research story on the artist by Malcolm Furniss)
Sunday, Nov. 6, 1 to 4 p.m.
Dragonflies Rule!
Dragonflies are described as "the ultimate predator both in the water and the air." Visitors will meet scientists and natural historians who will share information on the world of dragonflies.
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. More information is available on the website at https://bohart.ucdavis.edu or by contacting bmuseum@ucdavis.edu.

Yellowjackets, commonly known as "meat bees," in comparison to the "vegetarian" honey bees, will be among the wasps featured at the Bohart Museum of Entomology's open house from 1 to 4 p.m., Sunday, Sept. 25 in Room 1124 of the Academic Surge Building, 455 Crocker Lane, UC Davis campus. The theme: "Weird and Wonderful Wasps."
The open house is free and family friendly. A family arts and crafts activity is also planned.
"Yellowjackets are social wasps that build large, hidden nests," writes Lynn Kimsey, director of the Bohart Museum and a UC Davis distinguished professor of entomology, on one of her online fact sheets. "The nests are usually subterranean in rodent burrows or in cavities in trees, walls or attics.
"Yellow jacket nests can be huge with 50,000 to 100,000 workers," Kimsey points out. "In temperate climates these colonies are annual. Their nests die in the fall after producing new queens. New queens produced by the colonies in the fall spend the winter in protected places until spring when they found new colonies. Yellow jacket colonies can become perennial in warmer climates, such as in Hawaii and coastal California. In these situations the nests can become enormous, with millions of workers!"
Kimsey says that yellowjacket nests "can be distinguished from paper wasp nests because the brood cells are encased in a paper envelope so they can't be seen without taking off the outer envelope. These wasps generally feed on live prey, but the pest species, such as Vespula pensylvanica, will scavenge other sources of meat and sugar, including sodas, hamburgers and road kill. They will also visit aphids and scale insects for honeydew."
At the open house, 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. Kimsey will discuss the Asian giant hornet, Vespa mandarinia. 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.
Fairy wasps, in the family of chalcidoid wasps, are tiny insects. They include the world's smallest known insect, with a body length of only 0.139 mm (0.0055 in), and the smallest known flying insect, only 0.15 mm (0.0059 in) long, according to Wikipedia. The fairy wasps are found in temperate and tropical regions throughout the world. The family contains approximately 100 genera with 1400 species. All known fairy wasps are parasitoids of the eggs of other insects, Wikipedia says, "and several species have been successfully used as biological pest control agents."

Emily Meineke, assistant professor of urban landscape entomology, UC Davis Department of Entomology and Nematology, and coordinator of the department's seminars for the 2022-23 academic year, announced that all 11 seminars will take place both in-person and virtually at 4:10 p.m. on Wednesdays. in Room 122 of Briggs Hall except for the Nov. 9th and Dec. 7th seminars, which will be virtual only.
First in line is assistant professor Nicholas "Nick" Miller of the Department of Biology, Illinois Institute of Technology, Chicago, who will present his seminar on "Adaptation in the Cornfield, Research in the Classroom." The Zoom link: https://ucdavis.zoom.us/j/
Host is molecular geneticist and physiologist Joanna Chiu, professor and vice chair of the Department of Entomology and Nematology.
"Our interest in Diabrotica biology and evolution has lead naturally to an interest in Diabrotica genomics," Miller related. "Sequencing arthropod genomes is becoming relatively easy but analyzing and understanding those genomes remains hard and labor intensive. The flood of arthropod and other non-model genome sequences represents an opportunity for undergraduates to access research experiences that would otherwise be unavailable."
Research in the Miller lab focuses on the population genetics and evolution of herbivorous insects. "We mostly study species that are pests of agriculture," he says on his website. "Key areas of interest include: adaptation by insect pests to the technologies intended to control them, including genetically-modified crops and pesticides; the interactions of specialist and generalist herbivores to plant defenses; dispersal and movement of insects and the genes they carry."

To be a fly on Friday, what a day!
Entomologists who came up with "Friday Fly Day" are having a lot of fun posting images on social media of flies on Friday.
If you access WikiHow, "What to Do on a Friday Night," you'll find all kinds of suggestions. For instance:
- Watch a movie (that's do-able)
- Challenge friends to a game night (does anybody play games any more?)
- Treat yourself to a spa at home (a spa?)
- Give yourself a makeover (a what?)
- Cook a nice meal (how nice is nice?)
- Treat yourself to cocktail (some of us prefer coffee or water)
- Read a book or a magazine (did that, already)
- Start a new hobby (who has the time? Other hobbies are failing)
- Pamper your pet (he's already pampered; he has his own Facebook page, Vito and His Friends)
- Throw a karaoke or dance party (the neighbors would not like that)
- Work on an artistic or crafty project (some of us are crafty but not artistic)
- Start a bonfire (not in California!)
- Do something physically active (stationary bikes are good)
- and on and on and on....
Nowhere, but nowhere, does it say to take an image of a fly on Friday.
It doesn't have to be a fly on a wall. It can be a fly on a flower. But it has to be a fly on a Friday.
This one is a syrphid fly, aka flower fly or hover fly (and often mistaken for a honey bee) foraging on a blanket flower, or Gaillardia.
Gaillardia, a genus in the sunflower family, Asteraceae, is named for an 18th century French magistrate/botanist, Maître Gaillard de Charentonneau.
Maître Gaillard de Charentonneau, no doubt, never observed Friday Fly Day but being a botanist, he probably loved pollinators.
Cheers to a syrphid fly on "his" flower. (Well, it is a pollinator)
