Don Torino, who leads so many of the guided walks that the Meadowlands Commission and the Bergen County Audubon Society offer each walk, has a new column on Pipevine Swallowtails on wildnewjersey.tv.
Long ago, this most elegant of butterflies was a much more common sight than it is today. This is because their host plant – the the Pipevine (Aristolochia) – is the only plant that the Pipevine Swallowtail butterfly caterpillar will use!
About a hundred years ago, the Pipevine graced the porches and trellises of many homes, but as it fell in of favor the Pipevine Swallowtail, it fell in numbers. This butterfly has become hard to find and concentrated in small locations, including the Greenbrook Sanctuary in Bergen County.
We also had a Pipevine Swallawtail at DeKorte last summer, in mid-July.
