And this one, too.
And that one over there!
When UC Davis employees and their offspring visited the Bohart Museum of Entomology during the recent "Take Your Daughters and Sons to Work" Day, reactions ranged from awe to "wow!"
They held walking sticks (stick insects), Madagascar hissing cockroaches and tomato hornworms. Two youngsters held tarantulas. And all checked out the butterfly and beetle specimens.
One little girl, Olivia Bingen, 4, who was there with her father, Steve Bingen of the UC Davis Department of Music, was dressed in pink and asked the Bohart scientists if they had any pink butterflies.
"She likes pink," her father said. She also likes to play the violin.
The museum, founded in 1946 by the late Richard M. Bohart and now directed by Lynn Kimsey, UC Davis professor of entomology, is open to the public from 9 a.m. to noon and from 1 to 5 p.m., Mondays through Fridays, except on holidays. Admission is free.
Special weekend events, free and family friendly, are held throughout the year. The next weekend event is Moth Night from 8 p.m. to 11 p.m. on Saturday, Aug. 3. Blacklighting will take place just outside the museum. Inside, the attendees will visit the museum's displays and, outside, they will see what insects are attracted to the black-lighted white sheets.
Among those scheduled to host Moth Night are John "Moth Man" DeBenedictis; senior museum scientist Steve Heydon; entomologist Jeff Smith, who curates the Lepitopdera (butterflies and moths) section of the Bohart; and Greg Kareofelas, Bohart associate and naturalist.

James R. Carey, UC Davis distinguished professor of entomology, will discuss "What Can Insect Studies Tell Us about Longevity and Aging? Lots!" at his UC Davis Emeriti Association presentation at 11:30 a.m., Thursday, May 9 in the Walter A. Buehler Alumni Center, 530 Alumni Lane.
Among the topics he will cover:
- Are there lifespan limits?
- Evolution of lifespan extremes
- Male-female longevity differences
- Evolutionary demography of humans as informed by insect studies
- Three raging controversies in the demography of aging and lifespan in humans
Jeanne Calment of France (1875-1997), who died at age 122 (and 164 days), holds the record of the longest confirmed human lifespan.
An internationally recognized leader and distinguished scholar in insect demography and invasion biology, spanning three decades, Carey also researches health demography, biology of aging, and lifespan theory. He is the author of a landmark study published in the journal Science in 1992 that showed mortality of Mediterranean fruit flies (medflies) slows at older ages. Scientists last year confirmed that this also occurs in humans, citing the study of 105-year-old Italian women.
Carey, who joined the UC Davis Department of Entomology (now Entomology and Nematology) in 1980, directed an 11-university, $10 million, 10-year study on biodemography of aging from 2003-2013. He is also known for discovering Carey's Equality or the death distribution in a life table population equals its age structure. He teaches a popular longevity course that draws 250 to 300 students year, and recently authored a book on biodemography, to be published by Princeton University next year.
Carey drew a large, enthusiastic crowd at his Science Café presentation Oct.10 on "Are There Upper Limits to Human Lifespan?” in the G St. Wunderbar, Davis.
His talk on May 9 is open to all interested persons, according to UC Davis Retiree Center acting director Becky Heard. Those who opt for lunch, however, must RSVP by Monday, May 6 to the UC Davis Retiree Center at (530) 752-5182 or retireecenter@ucdavis.edu.

Long time passing
Where have all the flowers gone?
Long time ago
Where have all the flowers gone?
Girls have picked them every one
When will they ever learn?
When will they ever learn?"
--Pete Seeger
The late folksinger and social activist Pete Seeger (1919-2014) sounded many alarms, but a recent article in the New York Times Magazine struck a different but somewhat similar chord: the declining population of insects worldwide.
Brooke Jarvis's piece on "The Insect Apocalypse Is Here," published Nov. 27, should be required reading.
Basically: Where have all the insects gone? What does it mean? Why haven't we noticed? And what are we going to do about it?
Well, butterfly guru/entomologist Art Shapiro, distinguished emeritus professor of evolution and ecology at the University of California, Davis, has noticed. Shapiro has monitored butterfly population trends on a transect across central California for 46 years and maintains a research website at http://butterfly.ucdavis.edu/. The 10 sites stretch from the Sacramento River Delta through the Sacramento Valley and Sierra Nevada mountains to the high desert of the Western Great Basin. Shapiro visits his sites every two weeks "to record what's out" from spring to fall. The largest and oldest database in North America, it was recently cited by British conservation biologist Chris Thomas in a worldwide study of insect biomass.
In her article, Jarvis related: "In October, an entomologist sent me an email with the subject line, “Holy [expletive]!” and an attachment: a study just out from Proceedings of the National Academy of Sciences that he labeled, “Krefeld comes to Puerto Rico.” (See news article on Krefeld's "Insect Armageddon.")
That entomologist was Art Shapiro.
Pesticides, loss of habitat, diseases, climate change, and human encroachment--and more--are some of the reasons why our global population of insects is dwindling.
Shapiro, who engaged in a 90-minute conversation with author Jarvis (and suggested topics and interviews for the piece), is quoted as having one of the few long-term data sets about insect abundance in the United States.
"In 1972, he began walking transects in the Central Valley and the Sierras, counting butterflies," Jarvis wrote. "He planned to do a study on how short-term weather variations affected butterfly populations. But the longer he sampled, the more valuable his data became, offering a signal through the noise of seasonal ups and downs. 'And so here I am in Year 46,' he said, nearly half a century of spending five days a week, from late spring to the end of autumn, observing butterflies. In that time he has watched overall numbers decline and seen some species that used to be everywhere — even species that 'everyone regarded as a junk species' only a few decades ago — all but disappear. Shapiro believes that Krefeld-level declines are likely to be happening all over the globe. 'But, of course, I don't cover the entire globe,' he added. 'I cover I-80.'"
Jarvis quotes plant ecologist Hans de Kroon of Radboud University, the Netherlands, as characterizing the life of many modern insects as trying to survive from one dwindling oasis to the next but with “a desert in between, and at worst it's a poisonous desert.”
Why should we care? As Jarvis succinctly points out: "Insects are the vital pollinators and recyclers of ecosystems and the base of food webs everywhere."
So true.
Now the concern should not only be "Where have all the insects gone?" but "What are we going to do about it?"

The 92nd Street Y and the United Nations Foundation launched "Giving Tuesday" in 2012 in response to the troubling commercialization and consumerism in the post-Thanksgiving season (think Black Friday and Cyber Monday).
A very worthy benefactor on "Giving Tuesday" is the UC Davis Bohart Museum of Entomology, located in Room 1124 of the Academic Surge Building on the UC Davis campus.
Directed by Lynn Kimsey, UC Davis professor of entomology, the insect museum is named for its founder, noted entomologist Richard M. Bohart (1913-2007), a professor and former chair of the UC Davis Department of Entomology (now the UC Davis Department of Entomology and Nematology). He founded the museum in 1946.
When you think of the Bohart Museum, you think of excellence: excellent scientists, staff and volunteers. The insect museum houses
- nearly eight million insect specimens collected worldwide
- the seventh largest insect collection in North America
- the California Insect Survey, a storehouse of the insect biodiversity
- a live "petting zoo," comprised of Madagascar hissing cockroaches, walking sticks, tarantulas and praying mantids; and
- a year-around gift shop, which is stocked with T-shirts, sweatshirts, books, jewelry, posters, insect-collecting equipment and insect-themed candy
Another key part of the Bohart Museum outreach efforts: they host open houses at scheduled times on weekends throughout the academic year. On the campuswide Picnic Day, the Bohart draws as many as 4000 visitors. Thousands also attend the UC Davis Biodiversity Museum Day. (See video on YouTube).
Scientists throughout the world study the insect collection.
What does the Bohart need?
"Support for our outreach programs," said Kimsey. "I would love to get another photograph like the Biss one we have in the hall."
That would be like the newly acquired 5x6-foot photographic image or "microsculpture" of a cuckoo or emerald wasp, the work of noted British photographer Levon Biss. The “cuckoo” name refers to the fact that the female lays her eggs in the nests of unsuspecting hosts, including the sand wasp. The larvae of the cuckoo wasp then consume the host eggs, larvae and the stored food. The wasp is found throughout Europe but not in the United States.
Biss's intricate work, titled "Ruby-Tailed Wasp" (Parnopes grandior), encompasses more than 8,000 separate images, Kimsey said. “We chose it partly to honor the work that ‘Doc' Bohart did." Bohart spent much of his career studying chrysidid wasps or parasitoid wasps.
Biss, based in London, works across many genres, including news, sports, portraiture and insects. He credits his son, Sebastian, for developing his interest in insects. Sebastian found a ground beetle in their backyard and Dad photographed it. That led to a collaboration with the Oxford Museum of Natural History, where Biss gained access to the museum's historical collection of insects, including some collected by Charles Darwin.
Biss now creates micro-scale images for what he calls his Microsculpture series. Over a two-year period, he photographed 37 insects from the Oxford collection. To create the final insect portraits, he composites thousands of images using multiple lighting setups. Biss says he photographed most of them in about 30 sections, “each section lit differently with strobe lights to accentuate the microsculpture of that particular area of the body.”
In October 2017, Biss drew rave reviews for his TED talk, Mind-Blowing Magnified Portraits of Insects. That led to a world gallery tour of his images; his show is now at the Houston (Texas) Museum of Natural Science, July 13, 2018 through Jan. 13, 2019.
Unlike many insect museums, the Bohart Museum is open to the general public four days a week: Mondays through Thursdays, from 9 a.m. to noon and from 1 to 5 p.m., plus occasional, weekend open houses. Admission is free.
