On the grounds of the Harry H. Laidlaw Jr. Honey Bee Research Facility at the University of California, Davis, something as simple as a freshly watered potted plant will do.
Without water to ventilate and cool the hive, the wax inside an overheated hive on a hot day will melt and the brood will die.
However, if you see a honey bee collecting water, you might also see a European paper wasp (Polistes dominula).
These wasps need water to mix with their saliva and wood fibers to build their nests (right). They also bring back water for the offspring and to cool their nests.
Honey bees stand on the lip of the container or on rocks or sediment. They don't like getting their feet wet. Not so with wasps.

Without this "something," your table fare would be sparse.
And now, there's an official day to celebrate them.
The second annual National Honey Bee Awareness Day is set Saturday, Aug. 21.
The good folks at Pennsylvania Apiculture last year launched the first National Honey Bee Awareness Day to "bring together beekeepers, bee associations and clubs, as well as other interested groups and individuals to connect with communities and advance beekeeping."
They created a website filled with educational information, fun facts about bees, and how to help them survive.
This year the focus is on honey, local honey. The theme: "Local Honey-- Good for Bees, You, and the Environment!”
Of course, bees are more valuable for their pollination services than the honey they produce. Honey bees pollinate about one-third of the American diet. In fact, it's said that "between 50 to 80 percent of the world’s food supply is directly or indirectly affected by honey bee pollination," according to the National Honey Bee Awareness Day website. "Whether it’s pollination of apples, or pollination of the seeds to produce grain for livestock, the food chain is linked to honey bees. The world's production of food is dependent on pollination, provided by the honey bees."
So it was with great concern that we read last week about the killing of two bee colonies at an urban farm in San Francisco. Seems that someone invaded the Hayes Valley Farm--where the non-profit San Francisco Bee-Cause keeps its bees--and deliberately sprayed pesticides inside the openings of three hives. Two colonies collapsed and died--and not because of colony collapse disorder (CCD). The third hive sustained major losses.
Pesticides. Pesticides killed them.
Each hive held between 60,000 and 100,000 bees, so around 200,000 bees died.
Ironically, the bee hives were there not only for pollination, but as educational tools. And the honey was to be sold to benefit more educational activities.
Some theorize that the culprit hates or fears bees, and sought to eliminate them.
Perhaps the vandal would want to exist on foods NOT requiring bee pollination, such as wind-pollinated or self-pollinated crops like barley, corn, oats, rice, rye, sorghums and wheat.
Häagen-Dazs Honey Bee Haven at the Harry H. Laidlaw Honey Bee Research Facility on Bee Biology Road, University of California, Davis, is a study in diversity.
Bees, including honey bees, bumble bees, carpenter bees, leafcutter bees and sweat bees, along with other pollinators, share the pollen and nectar in the half-acre bee friendly garden.
Native pollinator specialist Robbin Thorp, emeritus professor of entomology, has logged some 50 different species of bees in the garden since its inception. He began a baseline monitoring process when the garden was a field of weeds, instead of dreams.
Today we spotted a yellow-faced bumble bee (Bombus vosnesenskii)
and a honey bee sharing a purple coneflower (Echinacea purpurea). Minutes later, a honey bee and a sweat bee occupied another coneflower.
The garden, planted last fall, changes daily, which it is meant to do. When the grand opening celebration of the haven takes place from 10 a.m. to 2 p.m. on Saturday, Sept. 11, expect to see scores of visitors--both humans and pollinators--sharing the garden.
You'll be hearing more about the CP2C.
The first-ever Congressional Pollinator Protection Caucus.
In keeping with 4th Annual National Pollinator Week, June 21-27, the Pollinator Partnership announced today that both parties of the U.S. House of Representatives have agreed to form the first Congressional Pollinator Protection Caucus (CP2C). Co-chairs are Rep. Alcee Hastings (D-FL) and Rep. Tim Johnson (R-IL).
Hastings and Johnson said they will be sending a “Dear Colleague” letter to fellow members of Congress to encourage their participation in the caucus.
As Hastings so accurately stated: “With one out of every third bite of food we humans consume dependent on bees and other animals for their pollination services, legislators need accurate information to help inform their positions."
“The caucus," Johnson added, "will seek out the best of pollinator science, economics and best practices."
Said Laurie Davies Adams, executive director of the Pollinator Partnership (P2): "This bi-partisan effort aims to support legislators’ understanding of the needs of their constituents with respect to pollinators, and we salute their cooperative drive to ensure that this issue gets the attention it deserves."
Kudos to Hastings, Johnson and the Pollinator Partnership.
Meanwhile, in conjunction with the CP2C launch, the Pollinator Partnership will host a briefing for members of Congress, staff, and the public on Thursday, June 24 at 3:30 p.m, at Longworth House Office Building, Room 1302.
Häagen-Dazs ice cream and Burt’s Bees will provide ice cream and lip balm for attendees. Häagen-Dazs, a strong supporter of UC Davis honey bee research at the Harry H. Laidlaw Jr. Honey Bee Research Facility, is committed to strengthening the health of the honey bees. (On Sept. 11, the public will celebrate the grand opening of the Häagen-Dazs Honey Bee Haven, a bee friendly garden planted last fall next to the Laidlaw facility.)
Burt's Bees is also a strong pollinator-supportive business.
Through research, public awareness, and concerted actions, we can all help preserve and protect our pollinators, especially honey bees.

Danger: Poison ahead.
Beekeepers do not like the California Buckeye (Aesculus californica).
Honey bees do, but they shouldn't.
It's poisonous to bees.
The California Buckeye, which grows as either a tree or a shrub 10 to 20 feet tall and can sprawl 30-feet wide, blooms in the spring. its candelabralike clusters of fragrant cream-colored blossoms attract hummingbirds, butterflies and bees.
About a week after honey bees work the blossoms, however, symptoms of buckeye poisoning appear in the hive.
"Many young larvae die, giving the brood pattern an irregular appearance," according to the booklet, Beekeeping in California, written primarily by a team of UC Davis entomologists and published in 1987 by the UC Division of Agriculture and Natural Resources. "The queen's egg-laying rate decreases or stops, or she may lay only drone eggs; after a few weeks, an increasing number of eggs fail to hatch or a majority of young larvae die before they are three days old."
What occurs: "buckeyed bees."
"Some adults emerge with crippled wings or malformed legs and bodies," wrote authors Eric Mussen, Norman Gary, Harry H. Laidlaw Jr., Robbin Thorp and Lee Watkins of the UC Davis bee biology program and Len Foote, then with the California Department of Food and Agriculture.
And, of course, with deformed wings, the bees cannot fly.
Buckeye poisoning can result in seriously weakened colonies or colony death. The authors also point out that "foraging bees feeding on buckeye blossoms may have dark, shiny bodies and paralysislike symptoms."
Solution: move the bees away from the buckeyes.
California Buckeye, according to the Sunset Western Garden Book, is "native to dry slopes and canyons below 4000-foot elevation in Coast Ranges and the Sierra foothills."
It is quite common along Pleasants Valley Road in Vacaville (Solano County), Calif. If you cross the picturesque country bridge, the Edward R. Thurber Bridge, you'll see it.
And honey bees foraging among the blossoms.
