Isn't it illegal to import stingless bees in the United States? It is.
So what's going on?
Members of the Pacific Coast Entomological Society and guests will find out when Martin Hauser, senior insect biosystematist with the Plant Pest Diagnostics Center, California Department of Food and Agriculture (CDFA), speaks on “The Curious Case of the Stingless Bees of Palo Alto” on Thursday night, Feb. 27 on the UC Davis campus.
The society will meet at 7:30 p.m. in the conference room of the Museum of Wildlife and Fish Biology, Room 1371 of the Academic Surge Building on Crocker Lane.
“In 2013 we found a stingless bee colony in Palo Alto in a tree,” Hauser said, “and I had a very hard time identifying the species—the genus is Plebeia—and I had no idea how they made it into California and where they came from. Many years later and many strange events later, I figured all these things out.”
Hauser will discuss his research and also reveal how long stingless bees have been recorded in California.
The 7:30 p.m. meeting begins with a general business session, followed by Hauser's talk.
A pre-meeting dinner will begin at 6 p.m. at the KetMoRee restaurant in downtown Davis. Members and entomology associates interested in joining the group for dinner should e-mail Catherine "Kady" Tauber at email@example.com before Tuesday, Feb. 25.
The society meets six to eight times a year, usually at the California Academy of Sciences, UC Berkeley, or at the CDFA's Plant Pest Diagnostics Center. Membership in the society, organized in 1901, is open to everyone--amateurs and professionals alike. The annual membership fee is $25, and $12.50 for students. The society publishes the quarterly journal, The Pan-Pacific Entomologist. and the Bits and PES Newsletter for members residing within commuting distance of San Francisco.
You've probably seen them hovering over flowers, which is why syprhids are commonly called "hover flies" or "flower flies."
Enter Andrew Young.
He's a UC Davis postdoctoral researcher with the Department of California Food and Agriculture (CDFA) and he researches syrphids.
Young, who specializes in Diptera taxonomy and phylogenetics at CDFA, will present a seminar to the UC Davis Department of Entomology and Nematology on "The Natural History of Syrphidae: from Pollinators to Parasitoids" at 4:10 p.m., Wednesday, Feb. 5 in 122 Briggs Hall, off Kleiber Hall Drive.
"Syrphidae (Dlptera) is a species-rich family of true fly, with over 6200 described species worldwide," he says in his abstract. "Often known as flower flies or hover flies, syrphlds are likely the most significant group of pollinators outside of the bees--especially in Arctic climates. While research into their pollination-related behavior is still nascent, other aspects of flower fly biology have been relatively well-studied."
"Adults of many species are well-known for their impressive mimicry of stinging Hymenoptera, and known larvae display a degree of habitat diversity that is unusually broad for a single family of Diptera. Many larvae are predators on soft-bodied insects such as aphids, and therefore, show potential for crop-pest management, while others are aquatic filter-feeders that may have value in waste-management applications." (See UC Integrated Pest Management Program website on syrphids; in their larval stage, they feed on aphids.)
Young says he will give an overview of the current understanding of flower fly phylogeny, followed by an exploration of the varied many adult and larval natural histories known to the group. He will emphasize "many of the little-known larval life histories that are still actively being discovered by dedicated field researchers. I will conclude by briefly discussing some of my past, present and future flower fly research."
Young studied Syrphidae in the lab of Stephen Marshall, professor of entomology at the University of Guelph, Ontario, Canada. Marshall and Young are among the six co-authors of Field Guide to the Flower Flies of Northeastern North America" (Princeton University Press, 2019), a book described as "a groundbreaking guide to flower flies in North America."
From the Princeton University Press website: "Flower flies are, along with bees, our most important pollinators. Found in a varied range of habitats, from backyard gardens to aquatic ecosystems, these flies are often overlooked because many of their species mimic bees or wasps. Despite this, many species are distinctive and even subtly differentiated species can be accurately identified." The guide includes more than 3,000 color photographs and 400 maps, covering all 416 species of flower flies that occur north of Tennessee and east of the Dakotas, including the high Arctic and Greenland. Each species account provides information on size, identification, abundance, and flight time, along with notes on behavior, classification, hybridization, habitats, larvae, and more."
Lynn Kimsey, director of the Bohart Museum of Entomology and professor of entomology at UC Davis, is the seminar host. Community ecologist Rachel Vannette, assistant professor, coordinates the weekly seminars.
Upcoming seminars for the winter quarter (See speaker list) are at 4:10 p.m. on Wednesday in 122 Briggs Hall.

Find the green darner.
Trying to spot the green darner dragonfly, Anax junius--so named because of its resemblance to a darning needle--is like finding the proverbial needle in a haystack.
But there it was, camouflaged in shrubbery on Sept. 23 in the Benicia Capitol State Historical Park.
This dragonfly, one of the most common and abundant species in the United States, as well as North America, is one of the few dragonflies that migrate. It migrates from the northern United States south into Texas and Mexico, according to Wikipedia. "It also occurs in the Caribbean, Tahiti, and Asia from Japan to mainland China."
The green darner is included in the Bohart Museum of Entomology's poster, "Dragonflies of California," available in its gift shop in Room 1124 of the Academic Surge Building, UC Davis campus. The poster is the work of entomologist Fran Keller, then a Ph.D student at UC Davis and now an assistant professor at Folsom Lake College, and Bohart associate and naturalist/photographer Greg Karoefelas. (See the Bohart Museum website.)
Did you know that the green darner is the official insect of the state of Washington, the Evergreen State? And it is one of the largest dragonflies in the order, Odonata? Males grow to 76 mm (3.0 in) in length with a wingspan of up to 80 mm (3.1 in)?
Females oviposit in aquatic vegetation, laying their eggs beneath the water surface. The nymphs (naiads) are aquatic carnivores, feasting on insects, tadpoles and small fish. The adults--they catch insects on the wing. Their prey includes flies and mosquitoes.
We remember several years ago when dragonfly/damselfly expert Rosser Garrison of the California Department of Food and Agriculture (CDFA) shared his knowledge of Odonata--and showcased some of his global specimens--at the Bohart Museum.
Fossil records show that they were the world's largest flying insects--some with wingspans measuring three feet--and they existed before dinosaurs. "Dragonfly relatives existed before the onset of the dinosaurs---Triassic Period, 250 to 200 million years ago,” related Garrison, a senior insect biosystematist at CDFA. “They are considered beneficial since both larvae---all aquatic--and adults are predators."
That green darner we saw in Benicia wasn't preying or sewing up people's ears (darners have been called "devil's darning needles") but it was darn camera shy.
Find the green darner!
So, here I am, an Asian lady beetle (Harmonia axyridis) perched on a rose bush in Vacaville, Calif., as dawn breaks. I'm eating aphids and minding my own beetle business, which consists of gobbling aphids and more aphids. And more aphids. Did I say more aphids? More aphids.
Wait, what's that? Something is heading straight toward me, its wings are flapping like crazy. Hey, I was here first. Go away!
Whoa, what are you doing? You've landed and you're licking me. What do you think I am, a honey stick?
That's what happened during a backyard encounter with an Asian lady beetle and a large syrphid fly. The fly, identified by senior insect biosystematist Martin Hauser of the Plant Pest Diagnostic Branch, California Department of Food and Agriculture, is a female Scaeva pyrastri.
Hauser and Lynn Kimsey, director of the Bohart Museum of Entomology and professor of entomology at UC Davis, agreed that the syrphid fly is "going after honeydew on the beetle's head." Honeydew is a sugary, sticky liquid that aphids secrete when they're feeding on plant juices.
"The beetle was full of honeydew from feasting on aphids," Hauser noted, "and that is what the fly was after."
He feuded with fellow entomologists, was a bigamist (married to two wives at the same time) and caused an uproar when a tunnel he dug in a Washington, D.C. alley collapsed in 1924 and some declared it the work of German spies.
All that will come to light on Thursday, April 28 at UC Davis when entomologist Marc E. Epstein talks about his newly published book on Dyar's eccentric life, Moths, Myths and Mosquitoes: The Eccentric Life of Harrison G. Dyar, Jr.
Epstein will present a lecture and book signing from 7:15 to 8:45 p.m., in the International House, 10 College Park, Davis.
The event, free and open to the public, is co-sponsored by Jay Rosenheim, professor of entomology, UC Davis Department of Entomology and Nematology, and by his department. Epstein is a longtime research associate and friend of Rosenheim's.
“As far as how I got into doing research on Dyar, at the onset it was related to my dissertation at University of Minnesota on Limacodidae (family of slug caterpillar moths, so called because their caterpillars bear a distinct resemblance to slugs),” Epstein said.
This led to Epstein and Henson to writing the American Entomologist article “Digging for Dyar: the Man behind the Myth.”
“Since the article appeared in 1992 I've accumulated a lot more information about Dyar, his genealogy, and even more significant connections between him and his favorite moths,” Epstein said.
The book, published by Oxford University Press, will be available for purchase at Epstein's talk.
Epstein is a senior insect biosystematist for the order Lepitopdera (butterflies, moths) with the Plant Pest Diagnostics Branch, California Department of Food and Agriculture. He is a research associate for the National Museum of Natural History (NMNH), Smithsonian Institution.
Harrison G. Dyar Jr. (1866-1929) was a Smithsonian entomologist of the early 20th century. He was a taxonomist who published extensively on moths and butterflies, mosquitoes, and sawflies. As a teenager, he studied insects, particularly moths. He received his bachelor's degree in chemistry in 1889 from the Massachusetts Institute of Technology, and his master's degree in biology from Columbia University in 1894. His doctoral dissertation (1895) dealt with airborne bacteria in New York City.
Oxford University offers this description of Moths, Myths and Mosquitoes:
"On September 26, 1924, the ground collapsed beneath a truck in a back alley in Washington, D.C., revealing a mysterious underground labyrinth. In spite of wild speculations, the tunnel was not the work of German spies, but rather an aging, eccentric Smithsonian scientist named Harrison Gray Dyar, Jr. While Dyar's covert tunneling habits may seem far-fetched, they were merely one of many oddities in Dyar's unbelievable life."
"For the first time, insect biosystematist Marc E. Epstein presents a complete account of Dyar's life story. Dyar, one of the most influential biologists of the twentieth century, focused his entomological career on building natural classifications of various groups of insects. His revolutionary approach to taxonomy, which examined both larval and adult stages of insects, brought about major changes in the scientific community's understanding of natural relationships and insect systematics. He was also the father of what came to be known as Dyar's Law, a pragmatic method to standardize information on insect larval stages as they grow. Over the course of his illustrious career at the U.S. National Museum, Smithsonian Institution from 1897-1929, Dyar named over 3,000 species, established the List of North American Lepidoptera, an unrivaled catalog of moths and butterflies, and built one of the nation's premier Lepidoptera and mosquito collections."
Epstein researches and writes on evolution and classification of moths and their biodiversity, and develops identification tools for moths that threaten agriculture. He served with NMNH's Department of Entomology (1988-2003), co-founding the department's Archives and Illustration Archives. He received his master's degree (1982) and doctorate (1988) from the University of Minnesota.
