"Tiger Swallowtail On Purple Coneflower" by Debbie Oppermann. One of my very favourite butterflies is the Canadian Tiger Swallowtail with it's beautiful, striking, large wings in yellow and black. This boldly striped Swallowtail was feeding,(nectaring) on the large purple Coneflower or Echinacea in my garden in Guelph Ontario Canada.
