Giant Swallowtail

A Giant Swallowtail in Erika’s Northfield garden. They have probably visited before, but they don’t appear every year. They disperse to the North Country sporadically in different years. This unusually hot summer would seem to be a candidate for their appearance. The fly all year in the southernmost United States, but only during the summer further north. Rescently they have become common in the Los Angeles Basin, and are their caterpillars are accused of destroying ornamental citrous leaves (Brock and Kaufman 2003).
