May 2014: Pipevine Swallowtail Butterfly

     

     

The lovely Pipevine Swallowtail Butterfly gets its name from the plant on which it lays its eggs, the Pipevine (Aristolochia sp.).  Dutchman's Pipe or Dutchman's Pipevine (Aristolochia macrophylla) is quite common on the Wolf River and Germantown Greenway.  If you look closely, you'll probably be able to see the striking black and orange caterpillars munching away, in addition to the unusual flowers which do indeed resemble a pipe!   Pipevine makes a nice native plant for backyards, too, providing abundant shade on a trellis,for example, along with striking flowers and larval food for a beautiful butterfly that depends on the presence of pipevines to reproduce.
