Of Sunshine and Swallowtail Butterflies…
A Perfect Spot for Sampling Lilac Nectar – An Eastern Tiger Swallowtail (Papilio glaucus) on Syringa vulgaris ‘Mme. Lemoine’
Sunshine at last! Finally, after weeks of rain and fog, golden light returned to the garden this week. And suddenly, the sultry air is filled with Tiger Swallowtail Butterflies —bright as the sun itself— fluttering about blossoming trees, shrubs and perennials; looking for a place to rest and a sample of sweet nectar. Here in my garden, the voluptuous French white lilacs —Syringa vulgaris ‘Mme. Lemoine’— seem to be the flavor of the week.
Papillon. Poetry in Motion…
Thank you, sweet papillon, for pausing to show off your bright, beautiful colors
More Information on the Tiger Swallowtail, and How to Attract this Beauty to Your Garden
The Eastern Tiger Swallowtail is commonly found at the edge of North American deciduous forests from early-mid spring through autumn. Adult females lay their eggs on host plants; including Ash (Fraxinius), Basswood (Tilia), Birch (Betula), Black Cherry (Prunus serotina), Lilac (Syringa), Mountain Ash (Sorbus), Poplar (Populus), Sweetbay (Magnolia) and Tulip Trees (Lirodendron). When caterpillars emerge, they hungrily eat their way through foliage, pupate and re-emerge as beautiful butterflies. The entire process takes little more than a month. In springtime, adult swallowtails feed on the nectar of flowers —particularly those forming clusters— such as lilac (Syringa), wild cherry trees (Prunus serotina), phlox, daphne, abelia, and viburnum. Later in the season, they feast upon the nectar of verbena (particularly Verbena bonariensis), butterflyweed and milkweed (Aesclepias), sweet pepperbush (Clethra alnifolia), asters, stonecrop (Sedum), butterflybush (Buddleja species*), Joe Pye weed (Eupatorium), bee balm (Monarda), phlox, heliotrope, pincushion flower (Scabiosa), Queen Anneâ€™s Lace (Daucus carota), gayflower (Liatris), and many other cultivated trees, shrubs, perennials, annuals and wildflowers. Provide a continuous supply of flowers and caterpillar host plants throughout the growing season to keep swallowtail butterflies in your neighborhood.
Sadly, a large number of butterflies are inadvertently killed each year —particularly as caterpillars— through the use of pesticides. Even organic methods of pest control can be harmful to beneficial insects, and should only be used in a targeted manner. Although Btk is an organically approved pesticide (made from a bacterium found naturally in soils), commonly and safely used to control harmful worms, it will kill beneficial caterpillars if used indiscriminately. So please, use organic pest controls sparingly, and with great caution. Familiarize yourself with all stages of the swallowtail butterfly lifecycle and pass along the information to your neighbors and friends.
