Look closely at a patch of California golden poppies and you may see a sweat bee (genus Halictus) collecting gold pollen. The pollen basket is on the hind legs but you'll see "gold" also dusting the head and abdomen.
Native bee, commonly known as "halictid bee." Native plant. In fact, the California golden poppy, Eschscholzia californica, is the state flower.
And the rumor that it's "protected" and you'll get arrested if you pick a poppy along a roadside is inaccurate.
The California Department of Fish and Wildlife sets the record straight on its website: "It is often believed that there are laws prohibiting the cutting or damaging of the California poppy because it is the state flower. While there is no law protecting the California poppy specifically, California Penal Code Section 384a(opens in new tab) requires written landowner permission to remove and sell plant material from land that a person does not own, and removing or damaging plants from property that a person does not own without permission may constitute trespass and/or petty theft. However, these laws do not prevent the collection of California poppies on private land by the landowner. California poppies are a beautiful and easy-to-grow addition to your garden, and although you may choose to pick them from your property, they last much longer in the ground!"
Want to learn more about native bees? California has some 1600 species of wild or non-managed bees. Be sure to read California Bees & Blooms: A Guide for Gardeners and Naturalists. It's the work of University of California authors, all with UC Berkeley connections: Gordon Frankie, now professor emeritus, UC Berkeley; Robbin Thorp (1933-2019), UC Davis distinguished emeritus professor who received his doctorate in entomology from UC Berkeley; photographer Rollin Coville, who holds a doctorate in entomology from UC Berkeley, and Barbara Ertter, curator at the UC Berkeley-based University Herbarium and Jepson Herbarium.
The Bohart Museum of Entomology is hosting an open house on bees, both wild and managed, from 1 to 4 p.m., Sunday, May 19 in Room 1124, Academic Surge Building, 455 Crocker Lane. It's free and family free.

Robbin Thorp (1933-2019), distinguished emeritus professor, Department of Entomology and Nematology.
Leal, professor of biochemistry in the Department of Molecular and Cellular Biology and former professor and chair of the Department of Entomology, said Thorp "epitomizes how emeriti contribute to UC Davis."
Thorp, a 30-year member of the entomology faculty, and a tireless advocate of pollinator species protection and conservation, retired in 1994, but he continued working until several weeks before his death on June 7, 2019, at age 85. In 2014, he co-authored two books: Bumble Bees of North America: An Identification Guide (Princeton University,) and California Bees and Blooms: A Guide for Gardeners and Naturalists (Heyday). He published more than 50 percent of his papers following his retirement."
“Robbin's scientific achievements during his retirement rival the typical career productivity of many other academic scientists,” said Steve Nadler, professor and chair of the UC Davis Department of Entomology and Nematology, at the time of the legendary entomologist's death. “His contributions in support of understanding bee biodiversity and systematics are a true scientific legacy.”

In his message, Chancellor May told the new emeriti: "You played a central role in keeping UC Davis at the forefront of excellence. Your continued engagement through teaching, research, volunteering and philanthropy is vital to our continued growth and success. So I encourage you to stay engaged with campus. The UC Davis Emeriti Association is here with resources and support for this newest chapter of your career. Please take advantage of it. Thank you for our dedication to UC Davis and congratulations on reaching this milestone."

One of them is Robbin Thorp. (Watch the video here.)

It's a celebration of (1) the accomplishments of the faculty entering a new chapter in their lives (2) the extraordinary retirement years of the late Robbin Thorp of the Department of Entomology and Nematology; and a congratulatory message by Chancellor Gary May.

"Summer is nearly over, and the fall quarter begins soon," said Leal, professor of biochemistry in the Department of Molecular and Cellular Biology and former professor and chair of the Department of Entomology (now the Department of Entomology and Nematology). "Let's pause and express our gratitude to our colleagues who transitioned to emeriti status this summer."
"For decades, they strived to make UC Davis a better place, and many will remain engaged with research, teaching, and public service," he noted.
Leal said the late Distinguished Emeritus Professor Robbin Thorp (1933-2019) epitomizes how emeriti contribute to UC Davis. Thorp, a 30-year member of the entomology faculty, and a tireless advocate of pollinator species protection and conservation, retired in 1994, but he continued working until several weeks before his death on June 7, 2019, at age 85.

Get off my turf!
The native bees known as Melissodes, the longhorned bees, start stirring in the early morning. First, they settle on a leaf or flower to warm up their flight muscles. Once ready to fly, they don't let up until late afternoon.
We look forward to seeing them forage and battle one another in our Mexican sunflower (Tithonia rotundifola) patch, a key part of our Vacaville pollinator garden.
The males are extremely territorial and try to bop other insects off "their" flowers. That includes bumble bees, butterflies and males of their species. Sometimes they aim for a spider or praying mantis on their real estate. Sometimes they lose. Why are the males such bee boppers? To protect their turf, according to the lateRobbinThorp, UC Davis distinguished emeritus professor. They are trying to save the resources for the females per chance to mate with them.
If you have a camera that will allow you to set a fast shutter speed, such as 1/8000 of a second, sometimes you can freeze the action. Otherwise, they are an elongated blur as they whiz by, seemingly faster than the proverbial "speeding bullet."
The book, California Bees and Blooms, a Guide for Gardeners and Naturalists (Heydey 2014), co-authored by University of California scientists, offers a closer look at Melissodes.
California is home to more than "1600 hundred species of undomesticated bees—most of them native—that populate and pollinate our gardens, fields, and urban green spaces," according to the authors (Gordon Frankie, Robbin Thorp (1933-2019), Rollin Coville and Barbara Ertter.) They explored 22 most common genera (and six species of cuckoo bees), describing each one's distinctive behaviors, social structures, flight season, preferred flowers, and enemies.
One of them is the Melissodes agilis that we find in our garden.

The English lavender drew her in.
And there she was, a yellow-faced bumble bee, Bombus vosnesenskii, foraging in our family's pollinator garden in Vacaville.
She buzzed from blossom to blossom, ignoring the honey bees, syrphid flies and...the photographer.
Ms. Bumble Bee was on a morning mission--to gather as much nectar as quickly as possible and return to her colony.
Sadly, this year bumble bees in our pollinator garden seem to be as "scarce as hen's teeth." (Since hens have no teeth, hens' teeth are so scarce as to be non-existent!)
This Bombus arrived June 4 and we haven't seen any since.
“Bumble bees provide an important ecological service--pollination," native bee expert Robbin Thorp (1933-2019), UC Davis distinguished emeritus professor of entomology, told us. "This service is critical to reproduction of a huge diversity of plants that in turn provide shelter, food (seeds, fruits) to diverse wildlife. The potential cascade of effects from the removal of even one localized pollinator may affect us directly and indirectly.”
In his retirement, Professor Thorp co-authored Bumble Bees of North America: An Identification Guide (Princeton University, 2014) and California Bees and Blooms: A Guide for Gardeners and Naturalists (Heyday, 2014).
