Englewood Cliffs, boat-basin area and stone-step trails
Bergen County, NJ
A long-known locality, with great quantities of Aristolochia durior growing on the cliffs and very steep slopes here, above the Hudson River at Englewood Cliffs. Many paths in disrepair as of this visit, but open. A majority of the Pipevine Swallowtails were females and many seen were in near-constant movement. At least 6+ males also observed, some seemingly attempting to mate with females. Also a few females apparently laying eggs on the Aristolochia vine’s leaves and/or nodes. My first re-visit here in many years, to specifically witness these majestic creatures. My visit also to honor 2 great naturalists of the local area, Nicholas Wagerik and Michael Bonifanti. Almost the only-other butterflies seen were Cabbage Whites which were less-numerous than these swallowtails. No other swallowtail species were noted. Road-access can be somewhat limited at times, and may be from the southward side of site.
