Add "California" to it and you have California Bees and Blooms: A Guide for Gardeners and Naturalists.
It's a book that's well-planned, well-executed, well-written and well-photographed.
Bees are hungry. What plants will attract them? How can you entice them to your garden and encourage them not only to visit but to live there?
The book, the first of its kind, profiles some of the most common bee genera found in California gardens; their preferred plants, both native and non-native; and how to attract them.
Most folks are familiar with honey bees and bumble bees. But what about the other bees, such as mining, leafcutting, sweat, carpenter, digger, masked, longhorned, mason and polyester bees?
Published by the nonprofit Heyday Books in collaboration with the California Native Plant Society, the book is the work of four scientists closely linked to UC Berkeley: urban entomologist Gordon Frankie, a professor and research entomologist at UC Berkeley; native pollinator specialist and emeritus professor Robbin Thorp of UC Davis (he received his doctorate in entomology from UC Berkeley); insect photographer and entomologist Rollin Coville, who holds a doctorate in entomology from UC Berkeley; and botanist/curator Barbara Ertter of UC Berkeley.
“This book is about urban California's bees: what they are, how and where they live, their relationships with ornamental flowers, and how to attract them to urban gardens,” they wrote. “It was written in the urgency of knowing that bees are critical to the health of our natural, ornamental and agricultural landscapes and that populations of some, perhaps many are in rapid decline.”
Frankie studies behavioral ecology of solitary bees in wildland, agricultural and urban environments of California and Costa Rica. He teaches conservation and environmental issues. He is involved in how people relate to bees and their plants and how to raise human awareness about bee-plant relationships.
Co-author Robbin Thorp, who retired in 1994 after 30 years of teaching, research and mentoring graduate students, continues to conduct research on pollination biology and ecology, systematics, biodiversity and conservation of bees, especially bumble bees. He is one of the instructors at the The Bee Course, affiliated with the American Museum of Natural History and held annually at the Southwestern Research Station, Portal, Ariz. The course is geared for conservation biologists, pollination ecologists and other biologists who seek greater knowledge of the systematics and biology of bees.
“The book is profusely illustrated with photos and drawings of bees and flowers, especially notable are the magnificent close-up images of bees by co-author Rollin Coville,” Thorp said.
Ertter thoroughly explores the anatomy of a flower. Bees and flowers constitute what the authors delightfully describe as "a love affair."
California's bees differ in size, shape and color, as do the flowers they visit. “The tiniest bees are ant-sized; the largest rival small birds,” the authors wrote. “Some are iridescent green or blue, some are decked out with bright stripes, some are covered with fuzzy-looking hairs.”
“Nature has programmed bees to build nests and supply their young with nutritious pollen and nectar, and their unique methods for collecting these resources are fascinating to observe. Their lives are dictated by season, weather and access to preferred flower types and nesting habitat.”
California Bees and Blooms lists 53 of urban California's best bee attractors identified through the Urban California Native Bee Survey. Among them: aster, bluebeard, catmint, California lilac or Ceanothus, cosmos, California sunflower, red buckwheat, California poppy, blanket flower, oregano, rosemary, lavender, gum plant, and salvia (sage). With each plant, they provide a description; origin and natural habitat, range and use in California; flowering season; resource for bees (such as pollen and nectar), most frequent bee visitors, bee ecology and behavior and gardening tips.
The book offers tips on how readers can “think like a bee.” It devotes one chapter to “Beyond Bee Gardening: Taking Action on Behalf of Native Bees.” In addition, the book provides quotes on bees and/or bee gardens from Extension apiculturist Eric Mussen (retired) of UC Davis: Ellen Zagory, horticulture director of the UC Davis Arboretum; and Kate Frey of Hopland, a designer of sustainable, insect-friendly gardens throughout California and in some parts of the world.

Give me an "A" (for excellence).
Give me a "B" (for bee).
Give me a "C" (for Cosmos).
Watching honey bees collect nectar and pollen on the showy Cosmos (Cosmos bipannatus) is not to be missed.
As if performing a ballet, the enchanting bees enter stage left and are such show-stoppers that you want to erupt with applause at every precise move. Bravo!
Cosmos is a spectacular annual with saucer-shaped floral heads, ranging in color from white and pink to lavender and crimson. It's a relatively late bloomer. In our family bee garden, they began blooming in late summer and are continuing into fall.
In their newly published book, California Bees and Blooms: A Guide for Gardeners and Naturalists, entomologists Gordon Frankie of UC Berkeley and Robbin Thorp of UC Davis teamed with photographer Rollin Coville (UC Berkeley-trained entomologist) and botanist Barbara Ertter (UC Berkeley) to offer interesting information on bee species and advice for growing and managing bee friendly plants. It's a "must-have" for every gardener and naturalist or would-be gardeners and naturalists. Did you know there are more than 1600 different species of bees in California alone, and some 4000 throughout the country?
One section goes into depth about plants, including Cosmos. You'll learn its description, origin and natural habitat, range and use in urban California, flowering season, resource for bees (nectar and pollen), most frequent bee visitors, and bee ecology and behavior. It's not surprising that the book, by Heyday, is published in collaboration with the California Native Plant Society.
And what are the most frequent bee visitors? "A wide variety of bee species, especially Melissodes robustior, Melissodes species, and Halictus ligatus. In the Central Valley, it attracts honey bees, Agapostemon texanus, Anthophora urbana, Xeromelecta californica, and Svastra obiqua expurgata."
The authors describe all those species--and more. Some we know generally as longhorned bees, sweat bees, metallic green sweat bees, digger bees, and sunflower bees.
Blooms. Bees. Beautiful.

We're receiving lots of inquiries about sleepovers ever since we began posting images of male longhorned bees, Melissodes agilis, sleeping on our lavender.
Boys' Night Out!
While the females sleep in their underground nests, the males cluster on stems. No, they don't have pillow fights or nightcaps but they do wiggle around a lot until they get comfortable.
Now the boys have moved from their favorite spot on the lavender (vertical sleepover) to the guara (horizontal sleepover). We suspect this may be due to several reasons: (1) The presence of three praying mantids in the lavender (2) the lavender is fading while the guara is flourishing and (3) the guara offers a definite height advantage, which may deter a few predators (but not birds).
Nevertheless, the boys start arriving for their nightly sleepover around 5 p.m. and don't budge until around 7 p.m., sometimes as late as 9 or 10.
One reader asked some interesting questions.
"There is a nightly cluster of boys on an aster stem in my front yard and I wanted to find out more about them. In particular, do they/can they/will they sting?"
No, boys don't sting--just the girls. As native pollinator specialist Robbin Thorp, emeritus professor of entomology at UC Davis, explains: "Boy bees cannot sting. They lack a stinger which is a modified ovipositor in their wasp ancestors. Occasionally a girl bee may spend the night out if she is caught by sudden drop in temperature. Usually she will not be part of a group sleep over. So don't attempt to handle unless you are confident you can tell boy bees from girl bees or they are too sleepy to defend themselves."
The reader also asked: "Typically how close to the girls' nest(s) do the boys' slumber? I want to try and make sure I don't touch it when planting at end of summer."
Says Thorp: "Boy sleeping aggregations are based on a suitable perch and not related to where females are nesting, but probably no more than 100 yards from the nearest female nest. Females nest in the ground and have rather distinctive round holes about the diameter of a pencil or slightly smaller, sometimes with small piles of dirt around them looking like mini-volcanos. The holes may be widely separated or clustered together depending on the species, but each female digs her own burrow."
Of course, not all slumbering bees in this area are Melissodes agilis, as Thorp points out. Some may be other species of the genus Melissodes and some may belong to the closely related Svastra obliqua.
The reader also wondered: "When watching the boys tonight, about ten of them started waking up and kicking each other. They finally settled down and started to nestle back in for the 'night'--it was only 6 p.m.--but I wasn't sure if my presence was getting them riled or they tend to act like kids sharing a bed?"
Says Thorp: "The boys usually settle in as the light dims in the evening. Cool, and drizzly conditions may modify bed time. Each establishes his own spot, so there may be some jostling for position initially."
We've noticed that, too. We've also noticed that the early morning risers--the carpenter bees, bumble bees, honey bees and syrphid flies--work around the slumbering Melissodes agilis. All that buzzing must sound like the human version of a chainsaw. "Will ya shaddup, already? Can't you see we're trying to sleep?"
Once the boys awaken, though, watch out! They'll dive-bomb the pollinators or any critter working or resting on "their" flowers. They're very territorial and determined to save the food source for the females of their species. The butterflies, including the Western tiger swallowtail, anise swallowtail, Gulf Fritillary and cabbage whites, don't linger when the boys target them.
And speaking of California bees, we're eagerly awaiting the arrival of the book, California Blooms and Bees: an Identification Guide for Gardeners and Naturalists. It's co-authored by research entomologist/professor Gordon Frankie of UC Berkeley; Thorp (who received his doctorate from UC Berkeley); and their UC Berkeley affiliates, photographer/entomologist Rollin Coville and floral/herbarium curator Barbara Ertter.
More than 1600 species of undomesticated bees call California their home. The authors focus on 22 of the most common genera and the flowers they frequent.
Meanwhile, you'll want to check out Frankie's UC Berkeley Urban Bee Lab website to read more about native bees and his exciting research.

Native bee enthusiast Celeste Ets-Hokin of the Bay Area is on a three-fold mission: She wants to protect North America's premier pollinators; she wants to inspire an appreciation for the importance and diversity of our native bees; and she wants people to create a habitat for native bees in their own gardens.
So, as an educational tool meant for all ages, Ets-Hokin originated the idea of a Wild Bee Gardens app to "show the dazzling diversity of North America's native bees." The app links native bees to many of the flowers they frequent.
The app is a comprehensive introduction to what the UC Berkeley zoology graduate calls "the essential world of native bees." It's comprised of some 300 photographs of native bees and their floral resources (primarily by entomologist/insect photographer Rollin Coville of the Bay Area) plus 100 pages "of extensive background and educational material in the form of guides."
Topics covered in the guides include:
- The role of native bees in our natural ecosystems
- The ecology and life cycles of native bees
- How to create a successful bee garden
- How to identify the native bee visitors that will appear in these gardens
Ets-Hokin also praised the "amazing job" of the design and development team, Arlo and Rebecca Armstrong.
Where to get Wild Bee Gardens? The I-Pad version is now available on the Apple App Store for the introductory price of $3.99. Those purchasing the app will receive the upcoming, expanded iPhone version at no additional cost, said Ets-Hokin, adding that they also will receive free downloads of all future enhancements.
Ets-Hokin devotes her time to the public awareness and conservation of native bees. This includes establishing a native bee demonstration garden with the Alameda County Master Gardeners at Lake Merritt, Oakland; and coordinating the publication of native bee calendars .

It's not your average garden variety calendar.
It's absolutely bee-utiful.
Native bees reign supreme in “Garden Variety Native Bees of North America,” a calendar produced by University of California alumni as a benefit for two non-profit organizations.
The perpetual calendar, the work of native bee enthusiast Celeste Ets-Hokin and entomologist/photographer Rollin Coville, both of the Bay Area, features native bees found throughout North America, including the leafcutter bee, bumble bee and sweat bee.
The macro photography is simply stunning. Through these photos, you can get up close and personal with bees you may never have even noticed. The ultra green sweat bees are especially spectacular.
Native pollinator specialist Robbin Thorp, emeritus professor of entomology at UC Davis, provided “considerable insight into the biology and ecology of several native bee genera,” said Ets-Hokin.
Also contributing extensively were UC Berkeley faculty members Gordon Frankie and Claire Kremen. Frankie shared his extensive knowledge of native bees in urban gardens. Kremen provided crucial information on native bee crop pollination services, based on her studies in Yolo County.
A portion of the proceeds will benefit the Great Sunflower Project, a national pollinator monitoring and conservation program based in San Francisco, and the Portland, Ore-based Xerces Society for Invertebrate Conservation, which protects native bees and their habitat throughout the United States.
Each native bee comes complete with information, such as the genus, common name, pollen/nectar sources, emergence time, nesting habit, and distinguishing characteristics.
For instance, you'll learn that bumble bees are excellent crop pollinators; they pollinate such crops as tomatoes, cranberries and blueberries better than honey bees.
You can attract bumble bees to your own garden by planting such pollen/nectar sources as giant hyssop (Agastache); manzanita (Arctostaphylos), ceanothus (Ceanothus); California poppy (Eschscholzia), sunflower (Helianthus); and beard tongue (Penstemon).
It's all there--all there on the calendar.
Coville, who received his doctorate in entomology from UC Berkeley in 1978, has been photographing insects and spiders for more than 25 years. He is collaborating with Thorp and Frankie on a number of projects, including a book on urban bees. It's due out next year.
Ets-Hokin, a UC Berkeley zoology graduate, devotes her time to the public awareness and conservation of native bees. For the past several years, she has collaborated with the Alameda County Master Gardeners in establishing a native bee demonstration garden at Lake Merritt, Oakland.
Coville takes many of his images there and now he has Ets-Hokin hooked on photography.
