You don't need lots of money and time to help bees, butterflies and other pollinators. One way you can assist them is simply by planting a few flowers. The key, experts say, is choosing varieties that have lots of nectar and pollen. (See "Create a Pollinator Garden.")

"We recommend that people go to local nurseries and look at their regional plant list," says entomologist Stephen Buchmann. "But we don't want people to think they can't plant nonnative flowers. It's just that many hybrid flowers have a nice scent and look attractive but when the bees go down they don't find nectar or pollen."

You don't have to plant acres of seedlings. Even a small border, a few pots or window boxes are helpful. Just plant as many different kinds of flowers as possible to provide a succession of blooms from early spring until the fall. "Any small effort is worthwhile," says Buchmann, "especially if you join in with your neighbors, because although small native bees have shorter flights and won't go far, honeybees, bumblebees and carpenter bees are strong fliers and will fly miles [in search of nectar and pollen]. They will cross over from patch to patch."

If you already have a vegetable garden, introduce some tall plants to attract and slow down pollinators. Sunflowers are good choices, as are climbing varieties such as morning glories, scarlet runner beans, red kidney beans, yellow and purple French beans, garden peas, sweet peas and nasturtiums. Grow them up a fence, trellis or bamboo poles. Bees will also visit plants that require pollination, such as cucumbers, squash, blueberries, pumpkins, melons, tomatoes, peppers and eggplants.

Another method for enticing pollinators is to provide and protect nesting sites, even to the point of encouraging (or at least tolerating) ground-nesting bees and wasps. (See "Build Artificial Nests for Bees.")

Once you've provided a pollinator garden and nests in your yard--or even if you don't--make sure you maintain a safe haven for pollinators. Practice organic gardening methods or use pesticides (preferably those derived from plants or microbes) only when crucial--and then in selective, small ways and always after sundown when the pollinators have retired for the night. Don't spray directly on the blossoms or use systemics, which travel throughout the entire plant. And it's wise not to use dust pesticides, which cling to hairy pollinators and are carried back to their nests. Better to spray bugs with insecticidal soap, or hose them off with a stream of water. Don't use herbicides and insecticides on your lawn, nor water it deeply--these practices can poison or drown ground-nesting pollinators.

It's also important to create a source of food for young pollinators and provide overwintering places for eggs and larvae. To do so, allow a corner of your backyard to naturalize with wild grasses, weeds and wildflowers (including Queen Anne's lace, burdock, borage, milkweed, evening primrose), and plant extra dill, parsley and carrots, which swallowtail butterfly larvae consume in quantity.

During hot, dry summer months provide water in very shallow birdbaths or pools where pollinators can easily alight around the edges to sip. And because some wasps and bees use mud to build their nests and butterflies like to congregate in muddy puddles, Buchmann recommends allowing a hose or faucet to drip.

And what if you have no garden but you would still like to pitch in? Create window-box gardens or plant in containers on balconies, stoops or rooftops. Join with your neighbors to create and maintain pollinator gardens in vacant lots, public gardens or local schools. Or call your local public works or highway department and offer to help establish or maintain corridors of native plants on median strips.

Create a Pollinator Garden

"I plant tiger and oriental lilies. Hummingbirds love them and also the red Philadelphia lilies," says Suzanne Batra, a scientist at the U.S. Department of Agriculture's Bee Research Laboratory. "Later there are goldenrods and asters, which are native--but they only grow in disturbed ground, in human clearings."

Hummingbirds arrive in most regions of the United States in April. When spring is cold and blooms are few, feeders filled with nectar water will attract hummingbirds as well as orioles and bees. (In the desert Southwest, bats will also visit feeders at night.) These pollinators will also be attracted to the native red trumpet honeysuckle.

Trumpet or cup-shaped flowers attract hummingbirds, butterflies, moths, bumblebees, carpenter bees, moths and other creatures with long tongues. These plants include lily, cardinal flower, native red trumpet honeysuckle, bee balm, trumpet vine, abelia, beauty bush, scarlet salvia, blue salvia, flowering tobacco, primrose, evening primrose, wiegelia, lily of the valley, single petunia, morning glory, nasturtium, snapdragon, foxglove, fuschia, pineapple and common sages, impatiens, poppies, red clover, scarlet runner bean, sweet peas, squash. In fact, any trumpet-shaped flowers that are red, orange or hot pink and, of course, high in nectar will attract hummingbirds.

Honeybees have somewhat shorter tongues than bumblebees. Even so, they can work a variety of the above flowers and, like butterflies and moths, also feed on tightly packed clusters of tiny flowers. Such shallow blossoms also provide easier access to the short tongues of the smaller native bees, wasps, beetles, blowflies and hoverflies (wasp and bee mimics). These plants include butterfly weed and other milkweeds, abelia, butterfly bush, Joe-pye weed, sweet William, lantana, lilac, viper's bugloss, hawthorn, hydrangea, spirea, goldenrod, phlox, heliotrope, penta, sweet allysum, yarrow, dandelion, staghorn sumac, thymes, mints, oreganos and white clover.

Other favorites include clematis, purple and yellow coneflowers, coreopsis, aster, zinnia, hollyhock, calendula, native sunflower, Mexican sunflower, cornflower, gaillardia, daisies (gloriosa, painted, shasta, ox-eye), blackberry, chrysanthemums, old-fashioned roses, tomato, eggplant and strawberry.

Trees and shrubs that provide pollen and/or nectar early in the season for butterflies, bees, wasps, moths and other insect pollinators include tulip poplar, dogwood, cherry, plum, pear and other fruit trees, blueberry, barberry, andromeda, azalea, mountain laurel, boxwood, holly, viburnum, daphne, witch hazel, red maple and willow.

Build Artificial Nests for Bees

One solution to managing wild bee colonies is to attract them to areas far from decks, patios and playing areas. You can do this by creating artificial nesting sites out of wood. Biologist Gary Paul Nabhan suggests drilling different-sized holes into blocks of softwoods, such as sugar pine and elderberry. "An astonishing variety of native bees and wasps can be accommodated that way," he says.

Adds beekeeper Raymond Williams: "There are not enough natural holes for wild bees, but you can increase their numbers by providing houses." He takes 4 x 4-inch blocks in lengths of at least 8 inches and drills 6 to 10, 6-inch-deep holes of 1/8 to 3/4-inch diameter. So the bees can chart a steady approach to their entrances, the blocks should be secured in a rigid position and attached under the eaves directly against the house or an outbuilding on the northeast side. They can also be nailed onto a tree in the shade or onto posts under shelters. "You don't want direct sun; it will cook them or they'll hatch too early in the spring when there's nothing for them to eat," warns Williams. He also recommends covering the front of the shelters with bird netting to keep out birds.

Bumblebee nests can be made of Styrofoam coolers or wooden boxes stuffed with upholsterer's cotton, which the bees need for insulation, according to Buchmann. To construct, drill a few drain holes in the bottom of a cooler or closed box, create a hole into which a piece of garden hosing will fit snugly and place the box six to 12 inches underground. Connect the nest entrance hole to the surface with a section of the hose.

One of the easiest ways to provide nests for hornfaced and stem-nesting native bees is to tie bundles of dried pithy stems (sumac, goldenrod, bamboo) or to stuff cans with straws and suspend them five to six feet off the ground in shaded protected sites. "If done in the spring, native bees will find these holey habitats and begin nesting," says Buchmann. "You will reap the benefits of bigger and better-tasting fruits and vegetables."

Bees will also turn stumps, dead branches and rotting trees into nesting habitats. The tunnels created in dead wood by beetle larvae are particularly attractive to nesting female leafcutter and mason bees.

What if you find a bee colony too near the house and need to remove it? Don't resort to chemical warfare--check your phonebook or call your county extension agent for the name of a local beekeeper. Most are willing to remove a colony (sometimes for a small fee) or they'll tell you how to smoke the bees out.
