Battus philenor question

It's February 18 and I got six B. philenor eggs on an A. fimbriata in
the yard today. This is kind of odd because if a female bothers to pass
through the yard to lay eggs she'll usually hit every pipevine out there
and leave anywhere from thirty to one-hundred eggs.
Here's my question: Has anyone had any luck with B. philenor larvae
surviving on wild ginger (asarum sp I think)? I'm wondering because
some texts include this as a host for the pipevine swallowtail and since
they rip through my supply of Aristolochia pretty quick I'd like a
backup host. Unfortunately, the bigger, more robust pipevines (like A.
durior) just don't do well here in Central Texas so we are stuck with
the smaller species.
One interesting observation I made a few years ago was that B.philenor
larvae would die if they were given a diet solely of A.grandiflora from
the start. But, after they made it through a couple instars on
A.fimbriata or A.erecta it seemed they would do fine on a diet of about
60% to 70% A.grandiflora and 30% to 40% A.fimbriata or A.erecta.
Strange.
