(Citheronia regalis overall spotty distribution

I have seen pictures of *Citheronia regalis* larvae on invasive burning


I wonder if this could maybe cause range expansion soon?  Also, I am
wondering if anyone knows if they still can be found in southern NJ (they
could be collected in Cape May County in the 80's I have heard)?
