Melanie, you mentioned comment on disposal of expired BF from site where you work. Pic is from BF House at Houston Museum of Nat. Sci., they apparently collected the deceased flyers, but then I don't know as this tray was just laying around in there.

I liked your comment regarding Zebra Swallowtails and Paw Paw trees - I also grow Paw Paws, the 2nd year they were there, I saw my first, and only (so far) Zebra ST; as you indicated, its a host plant therefor. Time permitting, I'll try to find pic of the Zebra ST, it's on a separate backup drive, about 9 yrs old.
