Wildlife Watch by Marian Harman – April 2018

Now that May has arrived and our spring trees, shrubs and wildflowers are blooming, we should give some thought to bees, our most important pollinators. Without them, we would have very few plants. Or as a recent USDA report states, “The world as we know it would not exist if there were no bees to pollinate the earth’s 250,000 flowering plant species.” You have probably read about the dire plight of the honeybee, a species introduced here from Europe in colonial times. Honeybees are succumbing in large numbers to a mysterious complex of ills called “Colony Collapse Disorder”. But perhaps you have not given much thought to our native bees that may be even more essential for most of our pollination needs. The United States Department of Agriculture reports that there are approximately 4,000 species of bees native to North America. These bees do a much better job at pollinating some plants than do honeybees. Native bees are especially effective at pollinating tomatoes, eggplants, pumpkins and other squashes, cherries, blueberries and cranberries. They also pollinate 80% of our flowering plants, trees, shrubs and wildflowers. Azaleas, for instance cannot be pollinated by honeybees, because of their long calyx. Native bumblebees pollinate azaleas by using an ingenious method called buzz pollination. They clasp the blossom and vibrate their abdomen to shake loose the pollen. Bees also use buzz pollination on tomato and blueberry flowers. Bees eat both pollen and nectar. Our native bees may either be colonial nesters (bumblebees) or solitary nesters (most other types). They may nest in holes in wood or underground. One type of native bee, the cuckoo bee, is even a parasitic nester, laying its eggs in another bees nest. There are fifty species of bumblebees native to North America.  Underground nests of the bumblebee species may be as long as a foot long with several nesting chambers branching off the main tunnel. Native bees come in all sizes and colors. Sweat bees are metallic green and blue or copper or gold. The tiny blue orchard bee pollinates fruit trees. Yellow-masked bees are black and yellow and resemble wasps. All bees, unlike wasps, have at least a little hair on them, and have two fused pairs of wings. Wasps have only one pair of wings. The honeybees’ plight seems to be caused by a combination of disease, nutrition and pesticides. Our native bees, being mostly non-colonial nesters are a bit less affected by disease. But, native bees are also declining, and that decline seems to be related to habitat loss and pesticide and herbicide use. Here are some things we can all do to encourage our pollinators. First, we can plant a pollinator garden. To avoid pesticides, adopt non-chemical solutions to insect problems. You can control aphids, for instance, by spraying them with water from a hose. In your yard, you should provide a source of water and a little bare ground and mud for nest building. Reduce the size of your lawn by planting a native plant garden from your eco-region. Mowing your lawn every other week is a good way to provide the clover, plantago and veronicas that bees thrive on. Standing dead trees also provide homes for many bees and birds. A fun project to do with kids is to make a bee-nesting house out of hollow twigs or reeds bunched together and packed into a container such as a small milk carton. The nesting twigs will be closed at one end and hung horizontal to the ground facing south. Bees will come into it to lay one or more eggs that they then seal up with mud. If you are lucky you may see the juvenile bees hatching in a few days. New England Wildflower Society website is a good source of information. Go to their website www.newenglandwild.org. As part of their new “Pollinate New England” effort, NEWFS is offering a free online pollinator garden course this spring and summer. You can take this course on your own computer and at your own speed. They are also offering free hands-on pollinator gardening workshops at various locations in New England. One of these is offered on June 26 in Wellesley, MA. You can buy native plants at The Garden in the Woods in Framingham, and at some other nurseries. For more information on how to help pollinators, go to the Pollinator Partnership website at www.pollinator.org. At that site you can see all the Pollinator Partner gardens in the country and register your own pollinator-friendly garden. Many thanks to all the flora and fauna reporters for the month of April. Please send reports by May 26 for next month’s column. You can call me at 692-3907, write me at 7A Old Colony Drive, Westford, or e-mail me at MarianCHarman@verizon.net.
