It's Labor Day, but honey bees aren't relaxing. They're out in force collecting nectar, pollen, water and propolis.
Ever seen them weighted down with huge pollen loads?
They seem to have "Herculean strength," don't you think? That's what Norman "Norm" Gary, emeritus professor of entomology at the University of California, Davis, writes in his book, Honey Bee Hobbyist: The Care and Keeping of Bees, considered the bible for hobby beekeepers.
"Ten pollen foraging trips a day is par for the typical pollen forager," Gary relates. "When pollen is abundant, a bee can gather a full load in as little as 10 minutes by visiting several dozen flowers...When all factors are favorable, bees from a strong colony can collect many thousands of loads a day. Incidentally, when.beekeepers describe their colonies as strong. they really mean populous--even though bees as individuals seem to have Herculean strength, flying with loads nearly as heavy as their body weight."
In an email, he wrote: "A worker honey bee weighs about 100 milligrams and are reported to be able to carry about 75 milligrams…approximately 75 percent of is body weight!"
Gary, now 90, served as a member of the UC Davis faculty from 1962-1994. He has kept bees for 75 years, starting at age 15.
As an aside, you may know him as not only a professor, scientist, musician, and author but one of the world's most incredible professional bee wranglers. He used to wear full-body bee suits and play the b-flat clarinet. (See Bug Squad blog of Nov. 30, 2016). He once trained bees to fly into his mouth to collect food from a small sponge saturated with his patented artificial nectar. He holds the Guinness World record (109 bees inside his closed mouth for 10 seconds) for the stunt.

A resident of Medina, Ohio, Kim died Sunday, Dec. 10 at his home of lung cancer at age 76. He served as editor of Bee Culture for 33 years, retiring in 2019. He authored numerous books and podcasts, including "5000 Years of Beekeeping in 24 Minutes (100)" with Jim Tew on Honey Bee Obscura.
We remember his talk at the 2021 California Honey Festival.
"If you want to be a beekeeper, you must think like a bee, not like a beekeeper," he related.
As a descendant of generations of beekeepers, I asked Kim why folks should keep bees. They "provide essential pollination, improve the genetics of the wild bee population in the area, ensure native plant populations," he said, "and because there is absolutely nothing more calming, soothing, enjoyable than being a part of that civilization, right in your backyard."
We remember when Kim addressed the 2017 Western Apicultural Society's 40th annual conference, held at UC Davis, where it was founded. He predicted that the nation's 250,000 beekeepers (who manage around 4 million colonies) will turn into a million beekeepers in five years.
Kim applauded "the incredible rise of new beekeepers in the last 10 years."
"The urban, suburban and country beekeepers are younger than the norm and we have more women beekeepers than ever," Kim told the crowd. "This isn't like the 1970s Green Movement--I'm old enough to remember that. It's got legs! But watch out for an ugly urban disaster like a major bee spill or bad honey recall."
"If I'm in beekeeping, pollination services is a sure bet," he said. "Beekeepers now get 200 bucks a colony for almond pollination in California. Pollination is more profitable than honey. Bee breeding? Queens can sell for as much as $40 or $50."
"In the United States, we eat on the average 1.2 pounds a year, but in Canada, it's 2.5 or 2.4 pounds." He lamented that unsafe and/or questionable honey from China floods our nation's supermarkets and is being sold at undercut prices. (Some statistics indicate that a "third or more of all the honey consumed in the U.S. is likely to have been smuggled in from China and may be tainted with illegal antibiotics and heavy metals"--Food Safety News.)
It's important for American beekeepers to label their honey "Made in America" or localize it by city or state, Kim said.
He also touched on such issues as honey bee health, nutrition, loss of habitat, poor quality forage, and pesticides.
The varroa mite/virus is the No. 1 problem for beekeepers, he said. "Other stressers include nutrition, nosema, pesticides...All of these can be fixed with money, increased diversity of bee stock, and a move away from both ag and in-hive legal and illegal chemicals."
Extension apiculturist emeritus Eric Mussen (1944-2022), serving his sixth term as president of WAS in 2017, commented at the time: "Kim Flottum has been a stalwart in U.S. beekeeping for decades. He ferrets out information on national, regional, and local beekeeping happenings and disseminates the news in various places, depending upon his role at the time. He has been associated with the A.I. Root Company; Gleanings in Bee Culture, and now editor of Bee Culture magazine. He is very active in the Eastern Apicultural Society and is well known by nearly every University and USDA scientist in the country. Kim consolidates all that information into some really interesting presentations in which he is not known for concealing his opinions."
Kim Flottum received his bachelor's degree in horticulture production from the University of Wisconsin and then worked as a researcher at the USDA Honey Bee Research Lab in Madison, where he specialized in crop pollination, pesticide problems with honey bees, and "honey plants" for the home landscape.
His career took him to Connecticut. He was elected president of Connecticut Beekeepers' Association. He served as publications manager and editor of Gleanings In Bee Culture, A. I. Root's monthly beekeeping magazine. He created a new magazine, BEEKeeping, Your First Three Years. He also served as president of the Ohio State Beekeepers' Association. He continued to keep bees in his backyard in Medina up until his death.
The son of the late Arnold and Edna Flottum of Turtle Lake, Wisc., Kim is survived by his wife, Kathy, of Medina; a daughter, Jessica of Akron; two stepsons, Matt and Grant Summers, both of Medina; and two brothers and two sisters, all from Wisconsin: Julie (Flottum) Hugg of Ashland; Bob Flottum of Chippewa Falls; Susan Flottum Zurcher of Wales; and Tom Flottum of Turtle Lake. A celebration of life is planned next spring. (See obituary)
A post on his Facebook page said simply: "RIP, Kim Flottum, you will be missed by all beekeepers."
And the bees.
His passion for bees, his wisdom about all things bees, his generosity, and his kindness, will never be forgotten.

On Labor Day, a federal holiday, we celebrate the our country's labor movement, our gratitude, and our achievements.
But there is no Labor Day holiday for the worker bee, one of three castes (queen, worker and drone) in a honey bee colony. No Labor Day holiday for the queen, either. In peak season, she will lay from 1000 to 2000 eggs a day. A laborious task, to be sure.
Most will be worker bees, the most needed of the three castes. Worker bees perform such age-related duties as nurse maids, nannies, royal attendants, builders, architects, foragers, dancers, honey tenders, pollen packers, propolis or "glue" specialists, air conditioning and heating technicians, guards, and undertakers. The worker bees (sterile females) run the hive. They're the "you-go" girls, the "you-got-this" girls and the "go-to" girls.
No "atta boys" here. The boys, or drones, have one job to do: mate with a virgin queen (in flight) and then they die. (Or as the late Eric Mussen, UC Extension apiculturist emeritus and a longtime member of the UC Davis Department of Entomology and Nematology faculty, would add "They die with a smile on their face.")
It's a matriarchal society.
But life is short for the foraging worker bees.
"Worker bees live for approximately five to six weeks in the spring and summer," writes author and retired bee scientist and bee wrangler Norman Gary, emeritus professor of entomology at the University of California, Davis, in his book, Honey Bee Hobbyist: The Care and Keeping of Bees.
"Those reared in the fall live for several months--long enough for the colony to survive the winter--and are replaced by young bees in late winter or early spring," says Gary, whose entire apicultural career spans 75 years, from student to retirement 26 years ago. (He still works with bees.)
For the foragers, collecting nectar and pollen can be dangerous. Their searching expeditions and forays can take them four to five miles from their hive. Due to predators (including birds, praying mantids and spiders), pesticides and other issues, many do not return home at night.
They put the "severe" in persevere.
What's not to admire about the honey bee? All hail Apis mellifera, not just on Labor Day, but every day of the year. You go, girls! You got this!

During the 11th annual National Moth Week, one thing's for sure:
Beekeepers won't be celebrating the beauty, life cycle, or habitat of the Greater Wax Moth (Galleria mellonella), also known as "the honeycomb moth." It's a major pest of bee colonies that aren't maintained well.
During the night, when we are sleeping, these female wax moths slip into bee hives and lay their eggs. The eggs hatch into larvae which consume honeycomb, leaving a destructive mess. The Greater Wax Moth is the most destructive comb pest, while the Lesser Wax Moth (smaller) is less serious.
In his book, Honey Bee Hobbyist: the Care and Keeping of Honey Bees, UC Davis emeritus entomology professor Norm Gary, explains that that the females wax moth "lays eggs at night in the cracks and cervices outside and inside the hive. Tiny tax-moth larvae tunnel through the combs--eating as they go--and lining the tunnels with silk that affords some protection from the bees, which would cast them from the colony. As the moth larvae grow larger, they are more exposed and vulnerable and are cast out of the hive by housecleaning bees."
Beekeepers remove the frames and freeze them, killing the larvae and any other pests that that might be in there--such as small hive beetles (Aethina tumida).
In its fact sheet on wax moths, the Mid-Atlantic Apicultural Research and Extension Consortium (MAAREC), says that "Beekeepers will never completely win the battle against wax moth. It is an insect well adapted for surviving around bee colonies."
MAAREC, however, describes the larvae as "a mixed blessing." The larvae are "raised for use as fish bait, animal feed, and scientific research and they are a good representative insect to use in Biology and Entomology classes. Beekeepers see the wax moth as a pest."
Meanwhile, it's National Moth Week, and a good time to head over to the Bohart Museum of Entomology Moth Night open house on Saturday, July 30 from 8 p.m. to 11 p.m. in Room 1124 of the Academic Surge Building at 455 Crocker Lane, UC Davis campus.
Indoors you'll see the Bohart Museum's global collection of moths, and outside, within a short walking distance, you'll see moths and other insects hanging on a white sheet in theblacklighting display. They are drawn there by an ultraviolet (UV) light. Yes, you'll see wax moth specimens.
"Yes, we have plenty of Greater Wax Moths as well as Lesser Wax Moths and a few other Pyralids that were reared from bumble bee nests," said entomologist Jeff Smith, who curates the Lepidoptera collection. (See Bug Squad blog about what Jeff Smith says about the collection)
The open house is free, family friendly and open to the public. Folks are invited to bring photos or moth specimens from their house, yard or neighborhood that they would like help in identifying, said Tabatha Yang, education and outreach coordinator. There also will be a craft activity, cookies, and "hot cocoa for anyone who needs help staying up past their bedtime," Yang quipped.
The Bohart Museum, founded in 1946 and directed by Lynn Kimsey, UC Davis distinguished professor of entomology, houses a worldwide collection of eight million insects. It also houses a live "petting zoo" (Madagascar hissing cockroaches, stick insects and tarantulas) and a insect-themed gift shop.

Ever seen a honey bee foraging on a daffodil?
In the early spring, blooms are few and far between. Daffodils are not usually considered "bee plants." But if nothing else is blooming, bees will head over to the daffodils.
On a Feb. 6th visit to the UC Davis Ecological Garden at the Student Farm, we watched a lone honey bee--probably from the Harry H. Laidlaw Jr. Honey Bee Research Facility apiary on Bee Biology Road--gathering pollen in a nearby bed of daffodils.
The bee's heavy load of daffodil pollen looked like pure gold.
Norm Gary, UC Davis emeritus professor of entomology, writes about the importance of pollen in his book, Honey Bee Hobbyist: The Care and Keeping of Bees: "The importance of pollen in the health and vigor of the honey bee colony cannot be overstated. Bees need a balanced diet. Honey satisfies the bees' carbohydrate requirements, while all of the other nutrients--minerals, proteins, vitamins, and fatty substances--are derived from pollen. Nurse bees consume large amounts of pollen, converting it into nutritious secretions that are fed to developing larvae. During an entire year, a typical bee colony gathers and consumes around 77 pounds (35 g) of pollen."
Daffodils belong to the genus Narcissus, named for a handsome hunter, who, in Greek mythology, fell in love with his own reflection (the word "narcissism" means "excessive self-love").
There was a lot of love that day in the daffodil bed.
