This gallery represents a study of what I believe is an Appalachian Tiger Swallowtail (Papilio appalachiensis). The assessment is based on its markings and size. I estimate that it's wingspan is at least 3.7" as determined by extrapolation of its wingspan against the width of the Water Iris on which it is feeding which are 3" from the end of one pedal to the end of another when viewed from the side with the petal ends hanging downward. This makes it significantly larger than Canadian Tiger Swallowtails that have wingspans that are less the 3.125".

Taken on 8-June-2017 in my backyard in Shrewsbury, Massachusetts.
