Moments after our German Shepherd completely shredded yet another doggie soccer ball, this butterfly landed. Was blown away by how closely they matched in color.

BTW, Google Images was pretty much useless in identifying this. Showed mostly a bunch of Etsy art. Pretty sure it's a Spicebush or Black Swallowtail.

Edit: I'm now convinced that this is a Red-Spotted Purple, or Limenitis arthemis. https://en.wikipedia.org/wiki/Limenitis_arthemis
