Zebra swallowtail butterly/Eurytides Marcellus
Yesterday we took a short 4 mile bike ride along the Susquehanna River on the Enola Low Grade Trail. Paw paw trees are plentiful along trails on both sides of the river, and the Mason Dixon Trail on the west side of the river is a great place to find paw paws and collect fruit, which may be ready in the next few weeks.
Anyways, paw paws are the sole host food for zebra swallowtail caterpillars, and they were everywhere along the trail. They were so hard to photograph, so this pic is from Wikipedia. This time of summer their tails are even longer than this. It was so nice to see so many!
