When a sweat bee and a honey bee share the same flower, the size difference is quite distinct.
We took this photo of a honey bee on a rock purslane (Calandrinia grandiflora) blossom.
Above it stood a tiny female sweat bee (probably Halictus tripartitus, according to native pollinator specialist Robbin Thorp, emeritus professor of entomology at the University of California, Davis).
Two bees. Two sizes. One blossom. One native. One non-native. The sweat bee is a native, and the honey bee was brought over here in the 1600s by the European colonists.
Speaking of honey bees, this is the first day to participate in TwitCause. The Häagen-Dazs brand is donating $1 per Tweet (up to $500 per day) today through Nov. 11 to support honey bee research at UC Davis.
Häagen-Dazs joined forces with ExperienceProject.com (EP), a San Francisco-based online community for sharing life experiences.

Bees buzz. People "Tweet."
Well, many people do.
It's generous of the Häagen-Dazs brand to donate $1 per Tweet (up to $500 per day) from Nov. 5 through Nov. 11 to support honey bee research at the University of California, Davis.
Häagen-Dazs, known for its superpremium ice cream and other desserts, is joining forces with ExperienceProject.com (EP), a San Francisco-based online community for sharing life experiences, to help the honey bees via EP’s TwitCause.
TwitCause, which EP launched in August, connects people with causes.
How can you do this--support UC Davis honey bee research by Tweeting?
“The easiest way for individuals to get involved is to visit www.twitcause.com,” said Erik Darby of EP. “There are directions on top of the page that detail how to follow, retweet, and make an impact around the honey bee cause on Twitter. Starting Thursday, Nov. 5, the designated TwitCause will be the Häagen Dazs Help-the-Honey-Bee campaign.”
“It’s an easy thing to do, and you don’t have to buy anything or send a letter to anyone,” said Tonya Iles, interactive manager for Häagen-Dazs.
Honey bees are responsible for the pollination of more than 100 crops, including fruits, vegetables, nuts, and seeds, providing 80 percent of the country’s pollination services, according to Extension apiculturist Eric Mussen of the UC Davis Department of Entomology faculty.
Häagen-Dazs (HD Loves HB, or Häagen-Dazs Loves Honey Bees) is a strong supporter of honey bee research at UC Davis. About 50 percent of their ice cream flavors depend on bee pollination. HD supports the work of bee virus researcher Michelle Flenniken, the Häagen-Dazs Postdoctoral Fellow. HD also supports the Häagen-Dazs Honey Bee Haven, a newly planted half-acre bee friendly garden located next to the Harry H. Laidlaw Jr. Honey Bee Research Facility on Bee Biology Road, UC Davis.
The haven is a year-around food source for honey bees and an educational experience for visitors.
Bees were the original "social network," as Lynn Kimsey, director of the Bohart Museum of Entomology and professor and vice chair of the UC Davis Department of Entomology, says
Now it's our turn to network.
Butterflies, honey bees and hover flies can't get enough of red buckwheat.
Tight clusters of pink blossoms, coupled with gray-green foliage, grace red buckwheat (Eriogonum grande rubescens), a California native.
It's good for the insects and good for the gardener. It's drought-tolerant.
We planted red buckwheat in our bee friendly yard several weeks ago, and among the first to find it were hover flies, aka flower flies.
Hover flies (family Syrphidae) hover over flowers like a sightseeing helicopter. Then they dip down and sip the nectar.
They're often mistaken for honey bees. Many an editor has published a photo of a "honey bee" that was in reality, a hover fly.
California buckwheat is one of the attractions in the newly planted Häagen-Dazs Honey Bee Haven, a half-acre bee friendly garden next to the Harry H. Laidlaw Jr. Honey Bee Research Facility on Bee Biology Road, UC Davis. It is serving as a year-around food source for bees and an educational opportunity for humans. A public celebration will take place next June.
Look for the buckwheat!
Looking for Nectar
Everything's coming up roses at the Bohart Museum of Entomology on the UC Davis campus.
Make that rose-haired tarantulas.
See, the Bohart not only houses some seven million insect specimens in its quarters in 1124 Academic Surge, but they have a few live ones, too.
Such as Madagascar hissing cockroaches, praying mantids and rose-haired tarantulas.
The Bohart, directed by Lynn Kimsey, professor and vice chair of the UC Davis Department of Entomology is one of our favorite places. You never know what you'll find.
We stopped by the museum last week and one of the Bohart student employees, Nanase Nakanishi, a UC Davis senior majoring in animal science, was caring for the occupants.
She and her colleagues were feeding the Madagascar hissing cockroaches, aka "hissers." While they were eating, Nanase picked up the rose hair, a favorite among budding entomologists and pet enthusiasts. On her red blouse, it looked like very much like a beautiful brooch. It's a soft, docile, gentle critter.
Nanase, who has worked at the Bohart for three years, feels very much at home there.
And, no wonder. Following graduation, she wants to study veterinary medicine and become a veterinarian.
Remember the ravenous light brown apple moth (LBAM) and all the controversy?
The invasive agricultural pest, from Down Under, soars high on the agenda at the Northern California Entomology Society’s meeting on Thursday, Nov. 5 in Concord. Also on the agenda: honey bee regulatory research.
The meeting, open to the public, will be held from 9:15 to 2:30 p.m. in the Contra Costa Mosquito and Vector Control District office, 155 Mason Circle, Concord.
Extension Apiculturist Eric Mussen of the UC Davis Department of Entomology faculty and secretary-treasurer of the society, said attendance at the meeting is free. The only fee is the $15 catered lunch.
In addition to LBAM and other exotic invasive pests, the meeting will include a talk on “Honey Bee Regulatory Research” by Mike Beevers of California Agriculture Research, Fresno.
“Mike is involved with research on the effects of pesticides on honey bees,” Mussen said. "Consideration of honey bees always has been important, but colony collapse disorder (CCD) has brought extreme attention to the possible consequences of bees becoming contaminated with insecticide residues, especially the ‘sublethal effects.’”
The meeting begins at 9:15 a.m. with registration and coffee.
9:30 a.m.: “Biological Control Agents for Light Brown Apple Moth,” Nick Mills of UC Berkeley
10:15 a.m.: “New Exotic Pests and Invasives of Regulatory Significance in California,” Kevin Hoffman, Plant Diagnostic Center, California Department of Food and Agriculture (CDFA)
11 a.m. “Responding to New California State Pests: Control Programs and Pesticide Products,” by Duane Schnabel, CDFA Pest Detection and Emergency Projects
11:45 a.m.: Annual business meeting, with election of new president
12 Noon: Catered lunch by Kinder’s Custom Meats ($15 per person, reservations required with Eric Mussen)
1:15: “Update on Light Brown Apple Moth Eradication Program,” by Laura Irons of CDFA’s Light Brown Apple Moth Program
2 p.m.: “Honey Bee Regulatory Research” by Mike Beevers, California Agriculture, Fresno
Those planning to attend should contact Mussen at (530) 752-0472 or e-mail him at firstname.lastname@example.org. For those needing continuing education hours in Laws and Regulations, California Department of Pesticide Regulation, this meeting will satisfy three hours, he said.
The Nor Cal society membership is comprised of university faculty, researchers, pest abatement professionals, students and other interested persons. Susan Sawyer of the Pest Detection/Emergency Projects, CDFA, has served as president for the last two years.
The society meets the first Thursday in February; the first Thursday in May and the first Thursday in November. Membership dues are $10 year.
