The three "F's" win hands-down: family, friends and food.
But "insects" should definitely added to that list. They are among the tiniest of critters on this planet, but think of their importance in our lives and in our ecosystems.
As British entomologist-zoologist George McGavin, author, academician, explorer and television presenter wrote in an article published in 2004 in The Guardian: "They are the most successful multi-cellular life form on the planet...Insects have endured for hundreds of millions of years. They have survived the numerous global upheavals and catastrophes that spelled the end for much greater and grander creatures and they will continue to be a major part of the Earth's fauna for many more millennia."
McGavin, an honorary research associate at both the Oxford University Museum of Natural History and the Oxford Department of Zoology, points out that insects are "the food of the world."
"Most of the higher animal species on Earth eat insect--they are the food of the world," he writes in his piece on Why I Love Insects. "All of the blue tit chicks in the British Isles alone consume 35bn caterpillars before they become adult. A single pipistrelle bat, the smallest bat species in the UK, has to eat between 2,000 and 3,000 insects most nights to stay alive."
McGavin also emphasizes the importance of pollinators and recyclers, that "we depend on bees for perhaps as much as a third of the food we eat....As recyclers, flies and beetles devour carcasses and clear prodigious quantities of dung every day."
We met George McGavin in July 2012 at a sunflower field in Winters. He and his crew were there to film a documentary on ultimate swarms, featuring Norm Gary, emeritus professor of entomology at UC Davis. Gary, an author, scientist and now a retired professional bee wrangler, clued him in on bee behavior.
Like many scientists, McGavin loves to share his enthusiasm for insects, something we all need to appreciate more and to support as much as we can. For example, the Entomological Society of America launched a Chrysalis Fund to bring insect education into the classroom. According to the website, it's "supported by donors dedicated to the mission of enhancing insect education for K-12 students. Teachers and educators with creative ideas for insect-themed programs or projects are encouraged to apply for funding." (On a side note, UC Davis distinguished professor Walter Leal donated his $1000 honorarium from the recent ESA Founders' Memorial Award Lecture to the Chrysalis Fund.)
So, what are we thankful for? Family, friends and food, for sure.
And the list also includes...insects.
A female and male Gulf Frit find one another.
Near them, Gulf Frit caterpillars hungrily munch the leaves. Soon they will form a chrysalis. From egg to larvae to chrysalis to adult.
If you'd like to learn to rear butterflies, silkworm moths, praying mantids or tarantulas, attend the UC Davis Bohart Museum of Entomology open house on “Arthropod Husbandry: Raising Insects for Research and Fun” from 1 to 4 p.m., Saturday, Nov. 16 in Room 1124 of the Academic Surge Building on Crocker Lane. It's free and family friendly.
UC Davis student Andrew Goffinet, a former UC Davis Bio Boot Camper, will be on hand to talk about rearing butterflies and moths. UC Davis entomology alumnus Lohit Garikipati will discuss praying mantids. Another entomology alumnus Nicole Tam, will talk about rearing insects in the Geoffrey Attardo lab as part of research projects. Doctoral student and Bohart associate Zaid Khouri's topic is how to rear tarantulas and millipedes for fun.
"We also will be discussing Madagascar hissing cockroaches (hissers) as good options for 'starter pets' for kids, and some of the problems with stick insects (walking sticks)," said Tabatha Yang, education and outreach coordinator. Visitors are invited to hold the hissers and stick insects and photograph them.
At 3 p.m., silkworm moth expert İsmail Şeker, a Turkish medical doctor who wrote a book about silkworm moths and the cottage silk industry in his home town, will show his newly produced video about the silkworm moth life cycle. Seker, also a talented videographer and a photographer, will answer questions following his 13-minute video presentation.
"This will be a fun open house for anyone considering a pet with an exoskeleton," Yang said."It will be good for educators to learn about classroom 'pets,' including those who do work with silk moths for life cycle lesson plans."
"Also, to kick off the holiday season we will have the unique wire jewelry by former entomology major Ann Kao, so people should be prepared to shop for some unique insect-inspired jewelry." A family craft activity is also planned.
This is the last open house of the year. The next open house will be on Jan. 18 when UC Davis graduate students from many different fields "will be talking/displaying about their cutting edge research with insects," Yang said.
The Bohart Museum houses a global collection of nearly eight million specimens. It is also the home of the seventh largest insect collection in North America, and the California Insect Survey, a storehouse of the insect biodiversity. Noted entomologist Richard M. Bohart (1913-2007) founded the museum. It maintains a live "petting zoo," featuring Madagascar hissing cockroaches, walking sticks or stick insects and tarantulas. The museum's gift shop, open year around, is stocked with T-shirts, sweatshirts, books, jewelry, posters, insect-collecting equipment and insect-themed candy.
Director of the museum is Lynn Kimsey, professor of entomology at UC Davis. The staff includes Steve Heydon, senior museum scientist; Tabatha Yang, education and outreach coordinator; and Jeff Smith, who curates the Lepidoptera (butterflies and moths) section.

It's Veterans' Day, and after paying tribute to the military veterans (my ancestors have fought in all of our nation's wars, dating back to the American Revolution--and my other half is a U.S. Air Force veteran), I slip out the back door to our pollinator garden to see where the insect action is.
Honey bees and a sole carpenter bee are buzzing on the African blue basil; Gulf Fritillaries are nectaring on the Mexican sunflower (Tithonia); and a cabbage white butterfly is sipping nectar from the Lantana.
But the passionflower vine (Passiflora) steals the show. A Gulf Fritillary has just eclosed from a chrysalis that resembles a thick wad of gum chewed up and spit out and left to mummify; several male Gulf Frits are fluttering around in search of females; and the offspring of previous reunions are crawling on the stems and munching what's left of the leaves.
Overhead, the California scrub jays glance down, as if trying to decide on their luncheon menu: a fat juicy caterpillar or the bird seed scattered in the feeder.
Their choice is clear. They forsake the fat juicy caterpillars for the bird seed. Tomorrow morning, however, there will be several caterpillars missing in action.
Where are you, Gulf Fritillaries?
The Gulf Fritillary (Agraulis vanillae) population seems to be diminishing this year around Solano and Yolo counties.
A few here, a few there, but not in the large numbers of last year.
Last summer the Gulf Frits overwhelmed our passionflower vine (Passiflora), their host plant, and skeletonized it.
Which is what we want them to do. We plant Passiflora for them, not for the fruit or the blossoms. On a good year, they eat it all--blossoms, fruit, leaves and stems--and look for more.
The history of the butterfly in California is as striking as its silver-spangled, reddish-orange coloring.
“It first appeared in California in the vicinity of San Diego in the 1870s,” says noted butterfly expert Art Shapiro, distinguished professor of evolution and ecology at the University of California, Davis. “It spread through Southern California in urban settings and was first recorded in the Bay Area about 1908. It became a persistent breeding resident in the East and South Bay in the 1950s and has been there since.”
Shapiro, who has monitored butterflies in central California since 1972 and maintains a research website at http://butterfly.ucdavis.edu, says the Gulf Frit “apparently bred in the Sacramento area and possibly in Davis in the 1960s, becoming extinct in the early 1970s, then recolonizing again throughout the area since 2000.”
It's making a comeback, but this year it doesn't seem to be "coming back" so much.
Want to attract the Gulf Frit? Plant its host plant and some of its favorite nectar plants. In our pollinator garden in Vacaville, their favorite nectar sources include the butterfly bush (Buddleia), Mexican sunflower (Tithonia) and lantana (genus Lantana.)
Plant them and they will come--if they're around!
Entomologists at the University of California, Davis, will share their love of insects with fairgoers at the 144th annual Dixon May Fair, which opened today (Thursday, May 9) and continues through Sunday, May 12.
Have a question about insects?
Entomologist Jeff Smith, who curates the Lepitopdera (butterfly and moth) section at the Bohart Museum of Entomology, UC Davis, and Alex Dedmon, a forensic entomologist and doctoral student at UC Davis, will be showing bee, butterfly, dragonfly and other specimens, and live insects from the "petting zoo," including walking sticks and Madagascar hissing cockroaches. Fairgoers are encouraged to hold them, photograph them and ask questions.
Smith and Dedmon will be at the fair on Saturday, May 11 from 11 a.m. to 3 p.m. in the Floriculture Building. Smith was honored in 2015 as a "Friend of the College," a coveted award presented by the College of Agricultural and Environmental Sciences. He saved the museum some $160,000 over a 27-year period through his volunteer service (See news story.)
Dedmon studies with forensic entomologist Robert Kimsey, an adjunct professor in the UC Davis Department of Entomology and Neamtology.
The Bohart Museum, directed by Lynn Kimsey, professor of entomology, is the home of nearly eight million insect specimens, plus a year-around gift shop and a petting zoo. The gift shop is stocked with books, jewelry, t-shirts, insect-collecting equipment, insect-themed candy, and stuffed animals.
The Bohart Museum, founded in 1946 by UC Davis entomologist Richard “Doc” Bohart (1913-2007), is open to the general public Mondays through Thursdays, from 9 a.m. to noon and from 1 to 5 p.m., plus occasional, weekend open houses. Admission is free. The next weekend event will be "Moth Night" on Saturday, Aug. 3 from 8 p.m. to 11 p.m. Further information is available on the Bohart Museum website or contact (530) 753-0493 or firstname.lastname@example.org.
