The area extends over to my neck of the woods.  I've been meaning 
to add a picture of some of the females to the Tiger Swallowtail

I agree.  Just about anywhere will work.  One of the commonest 
female, "non-normal" forms is almost all black with a yellow spot 
midway along the costa of the forewing.
