My favorite butterfly

My favorite butterfly is the Zebra Swallowtail. To me it is one of the most beautiful, etheral butterflies flying. I haven't been too successful in attracting them to my yard (yet), but I did see two different ones nectaring this year. I have a few small pawpaw trees in pots that I kept near my butterfly garden, but I didn't see any ZS eggs. I will order a few more pawpaws this coming spring in hopes of attracting them. Pawpaw leaves are the only plant that the caterpillars will eat. I've heard the pawpaw fruit is also very good.
