Zebra Swallowtail Butterfly yesterday.

Hi again, While boating with my older son on the Chesapeake Bay near North East, MD ( North East is the towns' actual name) we went ashore to explore the many rocks of volcanic origin. This exposure happens from the cliffs 'slumping' or caving in from erosion. Erosion eats out the bottom and the next layer to fall is the slip plane. Here we usually do see many Zebra Swallowtails and take them for granted. The entire Chesapeake Bay shoreline, minus cities, is usually a good place to see Zebras. Their host plant is Pawpaw, a short (25 foot max usually) tree. Here is a stunning shot of a Zebra Swallowtail Butterfly on the beach. Have a great day. Denis
