Back in 2010, Extension apiculturist Eric Mussen (now emeritus) and yours truly of the UC Davis Department of Entomology and Nematology decided that "The 12 Days of Christmas" ought to be replaced with insects.
Why not? "Entomology" means "insect science," and it's the holiday season so why not change "five gold rings" to "five golden bees?" And add some other insects and pests, as well.
Note that the original "Twelve Days of Christmas," published in 1780, features no insects. Zero. Zilch. Nada. Just a partridge in a pear tree, 2 turtle doves, 3 French hens, 4 calling birds, 5 gold rings, 6 geese-a-laying, 7 swans-a-swimming, 8 maids a'milking, 9 ladies dancing, 10 lords-a-leaping, and 11 pipers piping.
Didn't seem fair.
On the first day of Christmas, my true love gave to me, a psyllid in a pear tree.
On the second day of Christmas, my true love gave to me, 2 tortoises beetles and a psyllid in a pear tree
On the third day of Christmas, my true love gave to me, 3 French flies, 2 tortoise beetles and a psyllid in a pear tree
On the fourth day of Christmas, my true love gave to me, 4 calling cicadas, 3 French flies, 2 tortoise beetles and a psyllid in a pear tree
On the fifth day of Christmas, my true love gave to me 5 golden bees, 4 calling cicadas, 3 French flies, 2 tortoise beetles and a psyllid in a pear tree
On the sixth day of Christmas, my true love gave to me 6 lice a'laying, 5 golden bees, 4 calling cicadas, 3 French flies, 2 tortoise beetles and a psyllid in a pear tree
On the seventh day of Christmas, my true love gave to me 7 boatmen swimming, 6 lice a'laying, 5 golden bees, 4 calling cicadas, 3 French flies, 2 tortoise beetles and a psyllid in a pear tree
On the ninth day of Christmas, my true love gave to me 9 mayflies dancing, 8 ants a'milking aphids, 7 boatmen swimming, 6 lice a'laying, 5 golden bees, 4 calling cicadas, 3 French flies, 2 tortoise beetles and a psyllid in a pear tree
On the tenth day of Christmas, my true love gave to me 10 locusts leaping, 9 mayflies dancing, 8 ants a'milking aphids, 7 boatmen swimming, 6 lice a'laying, 5 golden bees, 4 calling cicadas, 3 French flies, 2 tortoise beetles and a psyllid in a pear tree
On the 11th day of Christmas, my true love gave to me 11 queen bees piping, 10 locusts leaping, 9 mayflies dancing, 8 ants a'milking aphids, 7 boatmen swimming, 6 lice a'laying, 5 golden bees, 4 calling cicadas, 3 French flies, 2 tortoise beetles and a psyllid in a pear tree
On the 12th day of Christmas, my true love gave to me 12 deathwatch beetles drumming, 11 queen bees piping, 10 locusts leaping, 9 mayflies dancing, 8 ants a'milking aphids, 7 boatmen swimming, 6 lice a'laying, 5 golden bees, 4 calling cicadas, 3 French flies, 2 tortoise beetles and a psyllid in a pear tree
"On the 13th day of Christmas, Californians woke to see:?? 13 Kaphra beetles, ?12 Diaprepes weevils, ?11 citrus psyllids, ?10 Tropilaelaps clareae, ?9 melon fruit flies, 8 Aedes aegypti, 7 ash tree borers, 6 six spotted-wing Drosophila, 5 ?five gypsy moths, 4 Japanese beetles, 3 imported fire ants, 2 brown apple moths, and a medfly in a pear tree."
Today the song is still making the rounds, but with some different pests--pests that challenge the entomologists in the California Department of Food and Agriculture:
On the first day of Christmas, my true love gave to me, a psyllid in a pear tree.
One the second day of Christmas, my true love gave to me, two peach fruit flies
On the third day of Christmas, my true love gave to me, three false codling moths
On the fourth day of Christmas, my true love gave to me, four peach fruit flies
On the fifth day of Christmas, my true love gave to me, five gypsy moths
On the sixth day of Christmas, my true love gave to me, six white striped fruit flies
On the seventh day of Christmas, my true love gave to me, seven imported fire ants
On the eighth day of Christmas, my true love gave to me, eight longhorn beetles
On the ninth day of Christmas, my true love gave to me, nine melon fruit flies
On the 10th day of Christmas, my true love gave to me, ten brown apple moths
On the 11th day of Christmas, my true love gave to me, eleven citrus psyllids
On the 12th day of Christmas, my true love gave to me, twelve guava fruit flies.
On the 13th day of Christmas, my true love gave to me, thirteen Japanese beetles
And, then, of course, there's that dratted pest, the Varroa destructor (varroa mite) from Asia, which arrived in the United States in 1987. Known as the No. 1 enemy of beekeepers, this external parasitic mite not only sucks a bee's lifeblood, but can transmit debilitating viruses. This is not what you want for Christmas--or any other time.

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.

Mark your calendars!
The next open house at the Bohart Museum of Entomology, located in Room 1124 of the Academic Surge Building on Crocker Lane, UC Davis campus, is set for 1 to 4 p.m., Sunday, Nov. 18. It's free and family friendly.
"The focus is urban entomology," said director Lynn Kimsey, UC Davis professor of entomology. "We'll have out examples of all the wonderful household pests/friends and garden pests, along with the kinds of things they inspect restaurants for."
Think of such beneficial insects in the garden as lady beetles (lady bugs) and praying mantids, and such pests as cockroaches and booklice in homes and restaurants.
What are booklice? These nearly microscopic insects, Liposcelis bostrychophila, or "psocids" (pronounced "so kids"), are common pests in stored grains. They're usually unseen because they're about a millimeter long--about the size of a speck of dust--and are transparent to light brown in color.
At the open house, look for scores of displays dealing with urban entomology. The UC Statewide Integrated Pest Management Program (UC IPM) will take part. A family arts and crafts activity is also planned.
The Bohart Museum, home of nearly eight million insect specimens, is the seventh largest insect collection in North America and houses the California Insect Survey, a storehouse of insect biodiversity.
In addition, the Bohart features 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.
Public weekend hours for the academic year 2018-2019 are:
- Sunday, Nov. 18, from 1 to 4 p.m.: "Bring It Home: Urban Entomology"
- Saturday, Jan. 12, from 1 to 4 p.m.: "Time's Fun When You're Studying Flies"
- Saturday, Feb. 16, times vary: (campuswide) Biodiversity Museum Day
- Saturday, March 9, 1 to 4 p.m., "Eight-Legged Wonders"
- Saturday, April 14, 10 a.m. to 3 p.m., (campuswide) UC Davis Picnic Da
The Bohart Museum's regular hours are from 9 a.m. to noon and 1 to 5 p.m. Mondays through Thursdays. It is closed to the public on Fridays, Saturdays and Sundays and on major holidays. Admission is free. More information on the Bohart Museum is available on the website or by contacting (530) 752-0493 or emailing bmuseum@ucdavis.edu.

Yes, you do eat insects!
Maybe not deliberately, as in those who engage in entomophagy, the technical term for eating insects. Think of chocolate chirp cookies! Think of cricket flour! Think of making a meal out of mealworms.
For thousands of years, "humans have harvested the eggs, larvae, pupae and adults of certain insect species from forests or other suitable habitats to eat," according to a page on the UC Riverside Center for Invasive Species Research website. "This practice is still common in many tropical countries where certain insect species grow to large sizes, and they are abundant and relatively easy to harvest year around. Insects as food are an excellent source of proteins, vitamins, fats, and essentail minerals."
In fact, as the UC Riverside officials point out: "there is a strong case in favor of mass rearing insects for food as this practice is probably less environmentally damaging than other forms of protein production." And, compared to eating cattle, eating insects is "five times more efficient at converting food into edible tissue."
Coming soon: insect farms in your community? Or in your cornmeal?
Last Monday, yours truly posted an article on "bugs in cornmeal" on the UC ANR Food Blog about an "insect farm" in the six-month-old cornmeal in our pantry. The cornmeal came to life in a see-through jar, with a tightly fitted lid, but you could barely see them.
Booklice. Nearly microscopic.
These Liposcelis bostrychophila, or "psocids" (pronounced "so kids"), are common pests in stored grains. They're usually unseen because they're about a millimeter long--about the size of a speck of dust--and are transparent to light brown in color.
They're called "booklice," although they are not lice. "Booklice can be scavengers and often feed on the bits of mold or fungi that grow on damp materials," entomologist Jeff Smith, who curates the Bohart Museum of Entomology's butterfly and moth collection, explained. "Very old, neglected food stuffs are also subject to them, and the key to prevention is to use food materials reasonably quickly and not store them for years, store them in a nice dry location and in airtight containers."
"They very well could have been in the food already when you bought it, but they're so common that you probably have some roaming around in the house all the time, just looking for something good to eat. They'll feed on dead bugs in window sills, stale pet foods, etc."
Statistics indicate that the average American unknowingly eats one to two pounds of insects a year. But the U.S. Food and Drug Administration "has very specific tolerances for the amount of residue in food stuffs," said Lynn Kimsey, director of the Bohart Museum of Entomology and professor of entomology at UC Davis.
