| Zebra Swallowtail (LEP6) Eurytides marcellus        This
  species has the most pronounced tail of all North American swallowtails.  Black stripes alternate with creamy white
  bands, and a scarlet streak crosses the middle of the hindwing.  A pair of red spots, then two blue ones,
  lead down to the long tail.  This
  striking butterfly is found only where pawpaw grows as the larvae feed on this
  plant.   |
