Limenitis arthemis
Found in field of grass and wildflowers between hills of deciduous forest.
Spotted at Whitewater State Park. Trailed after butterfly for awhile. When it did land it when down in the brush and was difficult to photograph. Identification reference: Butterflies of the North Woods by Larry Weber.
Hi Tamarac, what it looks like you have here is a female Eastern Black Swallowtail, at least in images 1 and 3. Image 2 is a different butterfly. It may be the same species but the markings are a bit different. It's hard to tell.
Red-spotted Purples are similarly colored but they lack tails, which your butterflies clearly have, and the color pattern is different.
Hope this helps!
