Then shortly after Wilson's death, entomologist Doug Tallamy, a University of Delaware professor, published an article in The Conversation that explored Wilson's lifelong passion for ants.
"Wilson, who died Dec. 26, 2021 at the age of 92, discovered the chemical means by which ants communicate," wrote Tallamy. "He worked out the importance of habitat size and position within the landscape in sustaining animal populations. And he was the first to understand the evolutionary basis of both animal and human societies."
"Each of his seminal contributions fundamentally changed the way scientists approached these disciplines, and explained why E.O.--as he was fondly known--was an academic god for many young scientists like me," Tallamy continued. "This astonishing record of achievement may have been due to his phenomenal ability to piece together new ideas using information garnered from disparate fields of study."
"Though I am an entomologist," Tallamy wrote, "I did not realize that insects were “the little things that run the world” until Wilson explained why this is so in 1987. Like nearly all scientists and nonscientists alike, my understanding of how biodiversity sustains humans was embarrassingly cursory. Fortunately, Wilson opened our eyes."
Last weekend I noticed some "little things that run the world" when I ventured out in the backyard to set out a spoonful of honey (not to "let the medicine go down" but to see ants come up).
What arrived: Argentine ants, as identified by Phil Ward.
Argentine ants are pests, says Ward, known globally for his expertise on ant systematics. These invaders from South America "form super colonies, which means different colonies don't fight each other; they're all cooperating," he told the UC Davis Biodiversity Museum Day/Month viewers. "And the other downside of Argentine ants is that they tend to eliminate native ants. So over the years I've lived in Davis, I have certainly noticed that native ants have declined as the Argentine ants have expanded. And they expand not just in, say, urban areas, but along certain natural habitats and one that they really like is the riparian habitat. So if you look along rivers and streams that are near urban areas, they're getting invaded by Argentine ants. And when they do, most native ants just disappear. This is a very tough aggressive ant and the mellow California ants can't handle an aggressive invader from South America. So they just disappear."
In his hour-long UC Davis presentation, Ward answered scores of questions, drawing viewers from as far away as Virginia. He illustrated his talk with ant images taken his former doctoral student Alex Wild (PhD from UC Davis in 2005), curator of entomology at the University of Texas, Austin, and a noted macro photographer (http://www.alexanderwild.com).
Ants, Ward said, live in long-lived colonies with (1) cooperative brood care (2) overlapping generations and (3) reproductive division of labor, the hall marks of eusocial behavior. He also pointed out:
- A typical ant colony contains a reproductive queen, numerous non-reproductive workers and brood (eggs, larvae, pupae)
- Colonies of ants can be thought of as superorganisms: tightly integrated and cooperative entities with complex systems of communication and division of labor (castes)
Ants originated about 120 million years ago (early Cretaceous), evolving from "wasp-like creatures," Ward said. They are members of the order Hymenoptera, and their closest relatives include honey bees, cockroach wasp and the mud daubers.
California has some 300 species of ants, Ward related, but thousands more are in the tropics, like Costa Rico. Globally, there may be as many as 40,000 to 50,000 species of ants, the professor estimated, but only about 14,000 are described.
"Ants have occupied almost all of the world's land surfaces, from deserts to rain forests," Ward said. "There's a few places they're absent. They're not in Antarctica, no surprise! They haven't colonized the Arctic and a few very high elevation tropical mountains, but apart from that, almost any place you go on land you'll see our friends, the ants. And they have assumed a quite a diverse array of ecological roles. Some of them are predators, others are scavengers, and some are seed collectors, and these habits vary tremendously among different species in different parts of the world."
Ants communicate largely by chemical (pheromones) and tactile means, Ward said, adding that their vision is "not particularly acute." He pointed out that that they lay a trail pheromones from the source of food back to the nest. They have alarm pheromones, causing other workers to act defensively. Chemicals also help ants distinguish their nest mates.
Ward's presentation, "All About Ants II," is posted on YouTube at https://youtu.be/d8eRNsD8dxo. You'll want to see why the UC Davis myrmecologist calls "My friends, the ants."
As for my little venture into "the ant world," I learned they are quite fascinating, but also quite difficult to photograph. They are indeed "the little things that run the world" and the emphasis should be on "run."
Even with a belly full of honey.

The open-to-the-public competition involved searching for the first-of-the-year bumble bee in the two-county area of Yolo or Solano; photographing it; and emailing the image to the Bohart Museum at bmuseum@ucdavis.edu.
The first bumble bee to emerge in this area is usually the black-tailed bumble bee, Bombus melanopygus, but another bumble bee, the yellow-faced bumble bee, Bombus vosnesenskii,is out early as well.
Both are considered "spring bees" because that is when their population is the highest, according to Thorp. Then their numbers "tail" the rest of the year.
Lynn Kimsey, director of the Bohart and a UC Davis distinguished professor, Department of Entomology and Nematology, announced Saturday that "we have the winners."
Not one winner, but two. No one species, but two.
Coincidentally, they each took their photos at exactly 2:30 p.m., Jan. 1 in the 100-acre UC Davis Arboretum and Public Garden as the bees foraged on manzanita.
And fittingly, they both knew and worked with Robbin Thorp (1933-2019), a global authority on bees and a UC Davis distinguished emeritus professor of entomology.
The event also marked the second consecutive year that a member of the Williams lab won. Last year postdoctoral researcher Charlie Casey Nicholson of the Williams lab and the lab of Elina Lastro Niño, claimed the prize by photographing a B. melanopygus at 3:10 p.m., Jan. 14 in a manzanita patch in the Arboretum.
As the 2022 winners, Page and Zagory will each receive a coffee cup designed with the endangered Franklin's bumble bee, a bee that Thorp closely monitored in its small range at the California-Oregon border. The cup features the image of the bee specimen, photographed by Bohart scientist Brennen Dyer, and designed by UC Davis doctoral alumnus Fran Keller, professor at Folsom Lake College.
The television program, Good Day Sacramento, featured the contest on Jan. 3. (See it here.)
Worldwide Collection. The Bohart Museum houses a worldwide collection of 8 million insect specimens, including 112 species of bumble bees, Kimsey said. Thorp spend much of his time at the Bohart where he identified bees and helped colleagues with their research.
Thorp, a 30-year member of the UC Davis faculty, retired in 1994 but continued his work on bees until his death at age 85 at his home in Davis. Known as a tireless advocate of pollinator species protection and conservation, he co-authored two books in 2014: Bumble Bees of North America: An Identification Guide (Princeton University) and California Bees and Blooms: A Guide for Gardeners and Naturalists (Heyday).
Said Zagory: “I indeed knew Robbin Thorp, one of the most generous and kind people I have ever met. Dr. Thorp invited me to do a page for their book (California Bees And Blooms: A Guide for Gardeners and Naturalists) about the UC Davis Arboretum All-Stars (pages 230 -232) and he edited a publication we created at the UC Davis Arboretum called Ten Bees and Ten Plants they Love that can be downloaded from the website at https://arboretum.ucdavis.edu/pollinator-gardening.
Page is a 2018 alumnus of The Bee Course, which Thorp co-taught from 2002-2018. The nine-day intensive workshop, geared for conservation biologists and pollination ecologists and considered the world's premiere native bee biology and taxonomic course, takes place annually in Portal, Ariz. at the Southwestern Research Station, part of the American Museum of Natural History, N.Y. (The 2021 winner--Charlie Casey Nicholson--is a 2015 alumnus of The Bee Course.)
Page said she was “also lucky enough to participate in a "Bumble Bee Blitz" organized by Thorp and the U. S. Fish and Wildlife Service in July 2016 on Mt. Ashland, where we searched for Bombus franklini and Bombus occidentalis-- two very rare West Coast bee species. We unfortunately did not find Bombus franklini, which is now recognized as an endangered species under the Endangered Species Act.”
Brilliant Scientist. “Robbin was a brilliant scientist and a dedicated advocate for bumble bee conservation,” Page said. “His death was a great loss and I wish more of my career could have overlapped with his time in Davis.”
As a doctoral candidate in entomology, Page researches and investigates “whether European honey bees compete with native bees for floral resources and how we can use well-planned floral enhancements to mitigate negative effects of competition."
How rare is it find Bombus vosnesenskii on Jan. 1?
In an email today, UC Davis doctoral alumnus and Thorp protégé Kim Chacon, said she has seen B. vosnesenskii near San Luis Obispo since Dec 26. She is a lecturer at California Polytechnic University (Cal Poly). "I think it is a very opportunistic species. In my research, that was one of the first emergers, the 6th genus actually. Robbin Thorp had an interesting theory about bumble bees dealing with a virus or other illness which was shifting the dominant species to vosnesenskii. I'm so happy both Ellen and Maureen won-- they are both awesome!"
"My congratulations, too," said bumble bee enthusiast/photographer Allan Jones of Davis, a friend of Thorp's. "I did not even go out considering the chilly weather. I expected it to be on the second day when we got up into the sixties, and with the ground so damp and cold, too. Hats off, brrrr."
Both bumble bee species have also been sighted and photographed in recent years on Dec. 31 and Jan. 1 in Benicia, Solano County.

If you're thinking about taking a walk in Yolo or Solano counties to celebrate the new year--or just to get some exercise in keeping with your New Year's Resolution (you did make one, didn't you?)--bring your camera.
You might find and photograph the first bumble bee of the year in a contest sponsored by the Bohart Museum of Entomology and memorializing bumble bee expert Robbin Thorp (1933-2019), UC Davis distinguished emeritus professor of entomology.
Participants are to capture an image of a bumble bee in the wild in either of the two counties and email the image to bmuseum@ucdavis.edu, with the details of time, date and place. The image must be recognizable as a bumble bee, said contest coordinator Lynn Kimsey, director of the Bohart Museum and a UC Davis distinguished professor of entomology.
The first bumble bee to emerge in this area is the black-tailed bumble bee, Bombus melanopygus, according to Thorp, who co-authored Bumble Bees of North America: An Identification Guide (Princeton University) and California Bees and Blooms: A Guide for Gardeners and Naturalists (Heyday).
Thorp launched the first unofficial bumble-bee-of-the-year contest several years ago with a small group of bumble bee enthusiasts/photographers: Allan Jones and Gary Zamzow of Yolo County, and yours truly of Solano County. Kim Chacon, then a UC Davis doctoral candidate and a Thorp protégé, joined us later. She is a 2019 alumnus of The Bee Course (co-taught by Thorp from 2002-2018). The nine-day intensive workshop, geared for conservation biologists and pollination ecologists and considered the world's premiere native bee biology and taxonomic course, takes place annually in Portal, Ariz. at the Southwestern Research Station, part of the American Museum of Natural History, N.Y.
Nicholson photographed B. melanopygus, in a manzanita patch at 3:10 p.m., Thursday, Jan. 14, 2021 in the UC Davis Arboretum and Public Garden to claim the honor. He is a researcher in the UC Davis Department of Entomology and Nematology labs of Professor Neal Williams, a pollination ecologist, and Extension apiculturist Elina Lastro Niño.
His prize? A coffee cup designed with the endangered bumble bee that Thorp closely monitored—Franklin's bumble bee, Bombus franklini, known to exist in a small area by the California-Oregon border. UC Davis doctoral alumnus Fran Keller, a professor at Folsom Lake College and a Bohart Museum scientist, designed the cup. Bohart scientist Brennen Dyer photographed the specimen from the Bohart collection.
The 2022 winner also will receive that prized coffee cup.
So, take a walk. Invite your camera. Keep that New Year's Resolution.
Game on!

Back in May of 2005, entomologist Fran Keller, a professor at Folsom Lake College and a UC Davis doctoral alumnus, interviewed E. O. Wilson for a presentation at the 2005 Entomological Society of America meeting in Fort Lauderdale, Fla.
This week remembrances are pouring in for Wilson, the legendary Harvard emeritus professor, biologist, naturalist and author who died Dec. 26 at age 92 in Burlington, Mass. (See UC Davis tributes on the Department of Entomology and Nematology website.)
Recognized as one of the world's most influential scientists, Wilson was known as “The Ant Man,” "The Father of Sociobiology," "The Father of Diversity" and “The Modern-Day Darwin," for his pioneering and trailblazing work that drew global admiration and won scores of scientific awards.
But among his peers, colleagues and mentees, he was known as "Ed."
"Our department of entomology helped fund my trip to Harvard,” Keller recalled, “and he agreed to meet me over the course of two days in May 2005. The ESA symposium took place in mid-December. I recorded our interview on a cassette tape,” she said, adding she hopes to publish it in a journal.
“We walked around the MCZ (Harvard Museum of Comparative Zoology) for a bit together, talking about species discovery, biodiversity and extinction,” she recalled. “We stopped at the display of birds and the ivory-billed woodpecker. We stopped at Darwin's finches on display. We went into the room where the rhinos were displayed and as we stared together at the rhinos, silent, I couldn't help myself and I began to cry. I apologized for my emotional display and said ‘It just makes me horribly sad that I may never get to see this animal in the wild, that it may be lost forever. I'm an entomologist, I don't know why this rhino makes me so sad. I didn't cry in front of the ivory-billed woodpecker.”
“After my interview with Ed, I bought the book in the MCZ, The Rarest of the Rare: Stories Behind the Treasues at the Harvard Museum of Natural History. In that book, it highlights the extinct and rare species held in the MCZ collections. One of those specimens is the last Xerces butterfly, which was caught by Harry Lange (UC Davis emeritus professor of entomology). Harry's quote in that book, ‘I didn't know it was the last one, I thought there would be more' and then my time eating lunch and then wandering the MCZ collection and chatting with Ed inspired me to create the Xerces t-shirt for the Bohart Museum of Entomology.”
One of Keller's mentors, Tom Schoener, studied with Wilson. “I worked on plant ecology and island biogeography for my undergrad research (Sacramento City College)," she said, "and continued that for awhile in grad school (UC Davis). Ed Wilson was one of the founders of island biogeography.” And, as a undergraduate at Sacramento City College, Keller was part of a field trip to hear Wilson speak at his 2002 book tour on The Future of Life.
Wilson's work, On Human Nature, won the Pulitzer Prize in 1979. He won a second Pulitzer in 1991 with The Ants, co-authored with colleague Bert Hölldobler. In 1990, the Royal Swedish Academy of Sciences awarded Wilson the Crafoord Prize in biosciences, the highest scientific award in the field. In 1996, Time magazine named him one of America's 25 most influential people. In 1977 President Jimmy Carter awarded him the National Medal of Science for his contributions toward the advancement of knowledge in biology.
Wilson, according to reports, always considered himself an Alabaman who went to Harvard, rather than a Harvard professor born in Alabama. Born June 10, 1929 in Birmingham, Ed graduated from the University of Alabama in 1949 with two degrees in biology, and received his doctorate in biology from Harvard in 1955. He joined the Harvard faculty in 1956. Although officially retiring in 1996, he remained active as an emeritus professor and honorary curator until his death.

The COVID-19 pandemic precautions and/or lockdown may interfere with it.
"As of now, no," says contest sponsor Art Shapiro, UC Davis distinguished professor of evolution and ecology, who launched the competition in 1972.
Remember the contest?
For scientific purposes, the UC Davis professor seeks to determine the cabbage white butterfly's first flight of the year in the three-county area of Sacramento, Solano and Yolo.
The traditional rules: Catch a live cabbage white butterfly, Pieris rapae, in the wild in one of those three counties, deliver it live to his department office, 2320 Storer Hall, UC Davis (during work hours, 8 a.m. to 5 p.m., Monday through Friday, with the full data, exact time, date and location of the capture) and if it's the first of the year, you win a pitcher of beer or its equivalent.
Shapiro, who maintains a research website at http://butterfly.ucdavis.
The butterfly inhabits vacant lots, fields and gardens where its host plants, weedy mustards, grow. The male is white. The female is often slightly buffy; the "underside of the hindwing and apex of the forewing may be distinctly yellow and normally have a gray cast,” Shapiro says. “The black dots and apical spot on the upperside tend to be faint or even to disappear really early in the season.”
Shapiro or his graduate students have often won the contest.
Shapiro has monitored butterfly population trends on a transect across central California since 1972 and records the information on his research website at http://butterfly.ucdavis.edu/.
Shapiro, a member of the UC Davis faculty since 1971 and author of the book, Field Guide to Butterflies of the San Francisco Bay Area and Sacramento Valley Regions, has studied more than 160 species of butterflies in his transect.
So suds for a bug in 2022? Well, maybe you can welcome in the New Year with suds...without a bug...
