Swallowtails Everywhere

This year we are seeing large quantities of Swallowtails of several types. We have an abundance of Eastern Tiger Swallowtails in both the yellow and black forms, Canadian Swallowtails [we are in an overlap area of habitat], Black Swallowtails and Giant Swallowtails in the area [although we haven't seen any of the Giant Swallowtails yet this year].
