An eastern tiger swallowtail butterfly fuels up Wednesday on nectar from a zinnia in a Lisbon garden. Although they are solitary creatures, often flying high in the treetops, they can sometimes be seen when a group of swallowtail males come together at damp places in the soil and drink water, according to the U.S. Forest Service. The water contains sodium ions and various amino acids, which appear to allow them to live longer. Adults of both sexes take nectar from a wide variety of native and exotic garden plants.
