Pipe vine swallowtails in Pa or NJ?

[Dale Clark]

I've found this *B. philenor* larval polymorphism here in north Texas as
well but as far as I can tell the reason for the difference is where you
find the larvae.  When oviposition occurs on *Aristolochia tomentosa* or
other pipevines found in shaded areas the larvae are dark.  Larvae on
low-growing species of *Aristolochia* such as *A. erecta* or *A. fimbriata*
that are in the full sun will have the lighter colored orange/red variety. 
I've reared them from a single female and get the two coloration
differences by placing one in shade and one in full sun.
