It's sad to see and say, but like honey bees, the bumble bee population is declining, and that decline is alarming. Public awareness can help turn this around.
That's why we're glad to see that the Xerces Society for Invertebrate Conservation, based in Portland, Ore., has just published a free downloadable booklet titled Conserving Bumble Bees: Guidelines for Creating and Managing Habitat for America’s Declining Pollinators.
The booklet outlines "the important role bumble bees play in both agricultural and wild plant pollination, details the threats they face, and provides information on how land managers can create, restore, and enhance high quality habitat," the authors said. "Importantly, these guidelines describe how land managers can adapt current practices to be more in sync with the needs and lifec ycle of bumble bees."
The booklet also includes bumble bee identification guides to both common and imperiled species in each region and lists important bumble bee plants.
One of the many plants they go for is lavender. In our yard we see as many as 10 yellow-faced bumble bees (Bombus vosnesenskii) foraging at one time. The bumble bees share the lavender with honey bees, syrphid flies, drone flies, blue and green bottle flies, carpenter bees, ladybugs, spotted cucumber beetles, butterflies, katydids, grasshoppers and a few predators, including crab spiders and jumping spiders.

If you've ever been to Angel Island or Alcatraz Island in the San Francisco Bay, you may have seen them.
And sometimes if you're fishing in the Bay, a bumble bee may land on your boat.
That was the case Monday, May 28 when the sportsfishing charter boat, The Morning Star, left its berth at Loch Lomond Marina, San Rafael, and headed out to the Bay to search for what skipper Gordon Hough calls "meals on reels."
The Morning Star encountered the bumble bee about two miles north of Angel Island, near the Richmond-San Rafael Bridge.
Native pollinator specialist Robbin Thorp, emeritus professor of entomology at UC Davis, later identified it from the photo below as a female Bombus vosnesenskii.
Nobody was catching any halibut or stripers at the time, so some of the anglers caught an image of the yellow-faced bumble bee.
"I thought it was remarkable to see a bee flying around in the middle of nowhere," said Hough.
"She was probaby just too lazy to fly the distance and decided to hitch a ride," quipped Thorp. "Wonder if she does a daily commute to find a better patch of flowers."
Thorp says that bumble bees are "larger, stronger fliers than honey bees and can potentially fly for several miles."
"They have occasionally been found on boats off shore, but like honey bees, they tend not to forage across wide strips of water," Thorp says.
UC Davis forensic entomologist Robert Kimsey, who does fly research on Alcatraz, has seen bumble bees on Alcatraz, too. No honey bees, but bumble bees.
As for Hough, he says he has no plans to offer bumble bee charters.

The yellow-faced bumble bees are back!
And amid the throes of winter and the promise of spring.
On a trip Feb. 27 to Bodega Bay, we spotted two yellow-faced bumble bees (Bombus vosnesenskii) about two miles apart.
They were both foraging on "The Pride of Madeira" (Echium candicans) on a sunny, but wind-whipped day in this Sonoma County coastal town.
The camera lens, the strong wind and the erratic flight of the bumble bees didn't allow us to get close, but the purple spiked flowers made a delightful sight.
See more images of this bumble bee, found throughout western North America, on Bug Guide.

The Häagen-Dazs Honey Bee Haven is not only a haven for honey bees; it's a haven for bumble bees and other native pollinators.
A yellow-faced bumble bee (Bombus vosnesenskii) buzzed around in the Bee Bliss salvia today, sharing the blossoms with honey bees.
The Häagen-Dazs Honey Bee Haven is a half-acre bee friendly garden located next to the Harry H. Laidlaw Jr. Honey Bee Research Facility on Bee Biology Road, UC Davis. It's an educational and research garden that provides year-around food for the Laidlaw bees and other pollinators.
On any given day, you'll see honey bees, sweat bees, carpenter bees, bumble bees and butterflies. As the weather warms, along will come crab spiders and praying mantids. Another highlight is all the art work created by the UC Davis Art/Science Fusion Program, directed by entomologist-artist Diane Ullman and artist Donna Billick and the six-foot-long bee sculpture, Miss Bee Haven, by Billick.
The garden is open from dawn to dusk. Folks can stroll the gardens on self-guided tours (no admission) and check out the labeled plants. Picnic tables offer places to have lunch--while the native pollinators have theirs.

So you want to attract native pollinators to your garden.
It offers a wealth of information, from identifying common bees of North America to helping you decide the best nectar-and-pollen plants for your garden.
The non-profit Xerces Society earlier announced that its Bumble Bee Garden Kit is available. The kit tells you how to attract bumble bees to your garden.
First the garden kit, then the book.
Bring on the pollinators!
