Seen any European wool carder bees lately?
European wool carder bees (so named because the female collects or cards plant hairs for their nests) are on the move.
The bees, about the size of honey bees, are mostly black and yellow. The females range in body length from 11 to 13 millimeters, while the males are 14 to 17 mm.
The males are known for being very territorial. They body-slam other insects to protect their turf, per chance to mate with the females.
The European wool carder bees, Anthidium manicatum, are natives of Europe. Their "immigrant ancestor" was first detected in the United States (New York) in 1963, and the species then began spreading west. The bees were first recorded in California (Sunnyvale) in 2007.
The species, according to research entomologist Tom Zavortink of the Bohart Museum of Entomology at UC Davis, was accidentally introduced into New York state. They were not purposefully introduced to pollinate alfalfa, as some reports allege, he said.
Writing in a 2008 edition of the Pan-Pacific Entomologist, Zavortink and fellow entomologist Sandra Shanks, now of Port Townsend, Wash., pointed out that several papers “have documented its spread from neighboring areas in the northeastern United States and southern Canada” and that the species has since crossed the country. It was confirmed in Colorado in 2005, Missouri in 2006, and Maine, Michigan, Maryland and California (Sunnyvale) in 2007, the entomologists wrote. Records show it was first collected in Davis on July 26, 2007.
It was well established in the Central Valley by 2008, according to Lynn Kimsey, director of the Bohart Museum of Entomology and a UC Davis distinguished professor of entomology.
We first encountered the European wool carder bee in Vacaville, Solano County, in the spring of 2010. Its plant preferences include lamb's ear (Stachys byzantine, in the mint family Lamiaceae), a perennial grown for its fuzzy, silvery gray-green foliage. It's also been collected in the figwort/snapdragon family (Scrophulariacae) and the pea and bean family (Fabaceae), according to the Zavortink-Shanks research.
In our pollinator garden, they seem to prefer foxgloves, lamb's ear, catmint and lavender. Yes, in that order...

What a show!
Last weekend we spotted female European wool carder bees (so named because they collect or card plant hairs for their nests) buzzing in and out of our snapdragons.
The bees, about the size of honey bees, are mostly black and yellow. The females range in body length from 11 to 13 millimeters, while the males are 14 to 17 mm.
The males are very territorial. As we mentioned in a previous Bug Squad blog, they put the "terror" in territorial. The males bodyslam other insects, as they try to protect their turf, per chance to mate with the females. We've seen the males terrorize the much larger Valley carpenter bees--bodyslamming them, dislodging them and chasing them away.

Usually the European wool carder bees are hanging around our foxgloves and catmint (neither is blooming yet) and our lavender (blooming but being ignored).
But snapdragons? We've never seen them foraging on snapdragons (Antirrhinum) until now. That's because we've never planted snapdragons until this spring!

Did you read the abstract published Jan. 17 in the journal ZooKeys about the newly discovered and named moth, Neopalpa donaldtrumpi?
No? Well, you probably read the news story. It went viral.
Somewhat overlooked was the role that scientists at the Bohart Museum of Entomology, University of California, Davis, played. The tiny moth was part of a desert insect collection that the UC Davis researchers loaned to evolutionary biologist and systematist Vazrick Nazari of Canada.
In sifting and sorting through the Bohart specimens, the brightly colored miniscule moth drew Nazari's attention. A new species! The yellow scales on the tiny moth's head reminded him of President-Elect Donald Trump's hairstyle.
Like a moth to a flame, Nazari decided on a name: Neopalpa donaldtrumpi.
Class: Insecta
Order: Lepidoptera
Family: Gelechiidae
Genus: Neopalpa
Species: N. donaldtrumpi
“The reason for this choice of name is to bring wider public attention to the need to continue protecting fragile habitats in the U.S. that still contain many undescribed species,” Nazari wrote in ZooKeys.
Bohart Museum associate/research entomologist Thomas "Tom" Zavortink and colleagues collected the tiny moth with the orange-yellow and brown wings in the Algodones Dunes, bordering Arizona and the Mexican state of Baja California. Tiny? It has a wingspan of less than one centimeter.
"We surveyed the insects of the Algodones Dunes for more than six years with a contract from the U.S. Bureau of Land Management," Kimsey said. "It was a really fun/interesting project. We collected nearly 2,000 species of insects from about 200 square mile of 'sand.' Six percent were new to science. The moth was collected in a Malaise trap in one of the washes on the east side of the dunes."
As for Zavortink, he's been a Bohart Museum associate since 2001. He's a former professor and chair of the University of Francisco Department of Biology. His career also includes research entomologist with the Walter Reed Army Institute of Research, Washington, D.C. He holds a doctorate in zoology from UCLA, where he also received his master's degree.
Zavortink is known for his mosquito identification for vector/mosquito control districts, California Department of Public Health, Latin American culicidologists and professional colleagues, and his bee identification for professional colleagues. He completed and published a survey of the bees of the Imperial Sand Dunes Recreation Area, Imperial County, for the Bureau of Land Management.
One of the bees he's researched is the European wool carder bee (Anthidium manicatum), discovered in New York in 1963 and in California in 2007. (See Bug Squad.)
Naming critters for people--from citizens to celebrities to presidents to other public figures--isn't new. President Barack Obama has nine species named for him (more than any other president). His namesakes include a long-legged, resourceful Northern California spider, Aptostichus barackobamai, and a colorful spangled darner, a perchlike fish, Etheostoma obama.
Having your name associated with a new species is considered an honor, scientists say. It's a permanent legacy, unlike the names of many streets, schools, other buildings, and parks, which can be subject to removal.
But here's a good thing: if you're interested in naming an insect for you or a loved one, the Bohart Museum offers a biolegacy program. For a sponsorship of $2000 (which helps fund the museum's research program), you can select a species for naming, and receive a framed photo and documentation (publication).
The Bohart Museum scientists describe as many as 15 new species annually, and their associates, "many more," Kimsey says. "We could use your help with the selection of new species names in the course of our research."
Some of the insects ready for adoption are pictured here. For more information, email bmuseum@ucdavis.edu or call (530) 752-0493.

Whether it's coming or going, you notice this pollinator's presence.
The European wool carder bee (Anthidium manicatum), so named because the female collects or cards "plant hairs" or "plant fuzz" to line her nest, is strikingly beautiful.
The bee is mostly black and yellow. The females, about the size of a worker honey bee, range in body length from 11 to 13 millimeters, while the males are 14 to 17 mm.
The males are very territorial. They put the "terror" in territorial. We see them hovering over the lavender in our yard and then bodyslamming honey bees. This behavior results in very skittish honey bees; no wonder honey bees don't linger on the blossoms long when their cousins show up!
The European wool carder bee, as its name implies, is a non-native. But so, too, are the honey bees, which European colonists brought to America in 1622.
The wool carder bee, according to research entomologist Tom Zavortink of the Bohart Museum of Entomology at UC Davis, was accidentally “introduced into New York state, presumably from Europe, before 1963.” It was not purposefully introduced to pollinate alfalfa, as some reports allege, he said.
Writing in a 2008 edition of the Pan-Pacific Entomologist, Zavortink and fellow entomologist Sandra Shanks, now of Port Townsend, Wash., pointed out that several papers “have documented its spread from neighboring areas in the northeastern United States and southern Canada” and that the species has since crossed the country. It was confirmed in Colorado in 2005, Missouri in 2006, and Maine, Michigan, Maryland and California (Sunnyvale) in 2007, the entomologists wrote.
Records show it was first collected in Davis on July 26, 2007.
The wool carder bee nests in convenient cavities such as old beetle holes and hollow stems, according native pollinator specialist Robbin Thorp, emeritus professor entomology at UC Davis. Its plant preferences include lamb’s ear (Stachys byzantine, in the mint family Lamiaceae), a perennial grown for its fuzzy, silvery gray-green foliage. It’s also been collected in the figwort/snapdragon family (Scrophulariacae) and the pea and bean family (Fabaceae), according to the Zavortink-Shanks research.
And in our yard, it seems to prefer three plants: lamb's ear, catmint, and lavender.

A good time to photograph the European wool carder bee is in the early morning when it's warming its muscles to prepare for flight.
It lies perfectly still.
That's what it did in our yard last weekend. It warmed itself on the sunny side of a leaf.
Not unlike the sunny side of a street...
The European wool carder bee (Anthidium manicatum), so named because the female "cards" or collects plant material to line her nest, is a relative newcomer to the United States. UC Davis research entomologist Tom Zavortink of the Bohart Museum of Entomology says it was accidentally introduced into New York State before 1963.
Writing in a 2008 edition of the Pan-Pacific Entomologist, Zavortink and fellow entomologist Sandra Shanks now of Port Townsend, Wash., pointed out that several papers “have documented its spread from neighboring areas in the northeastern United States and southern Canada” and that the species has since crossed the country. It was confirmed in Colorado in 2005, Missouri in 2006, and Maine, Michigan, Maryland and California (Sunnyvale) in 2007, the entomologists wrote.
The bee is mostly black and yellow. At first glance, its stark markings remind you of a yellowjacket. The females, about the size of a worker honey bee, range in body length from 11 to 13 millimeters, while the males are 14 to 17 mm.
The males can be aggressive in defending their territory, sometimes body-slamming honey bees and other insects to the ground.
Native pollinator specialist Robbin Thorp, emeritus professor of entomology at UC Davis, says that this kind of contact has a purpose. The male wool carder bee is "merely defending its territory from honey bees and other flying insects to keep the area free of potential competitors that might interfere with its mating opportunities," he says.
One thing's for sure: they do move fast!
Except in the early morning when they're warming their flight muscles...
