Gee, Ive, I really don't know. Let's see ----- let me find the butterfly forum --- they will be able to answer those things. BRB!
Here is the entire forum:

And I think you would just start a new thread there asking your questions OR try posting those beautiful photos on the butterfly photo thread & you might attract more attention.
I'm so glad you have a butterfly friendly garden!
And isn't it cool that you have attracted the lovely Giant Swallowtail & have all the right plantings for it? I just love stories like that!
